There is no crying in electronics. 2. Sometimes in troubleshooting, you gotta tear down and work your way back up.

I've got about 2 months left to complete them. I'll update you guys. But I am going to start second one and just be more careful with the sewing. I might start with just the neopixels then add the leds afterwards too.

candid cosmos Mar 15, 2018, 2:53 PM

@remote oar Good to see you're getting things to work.

#

in your code, you might need to put the seBrightness command after the pixels.begin if your neopixels have not dimmed to comfortable working brightness.

#

  pixels.begin(); // This initializes the NeoPixel library.
  pixels.setBrightness(BRIGHTNESS);```

light wigeon Mar 21, 2018, 1:53 AM

#

If you build the extra smoke into it you can just spit one off.

#

Can you imagine a special LED matrix where you solder them all in, and the goal is to spectacularly puff one of 'em but none of the others? Like a flashbulb array.

#

Flashbulbs had like a network of tiny filaments (think very fine steel wool, but not near as dense). When you energized the flashbulb, it went off with a very bright light, and maybe made a sound, too.
Then it was toasted -- often the plastic melted a little.
Flashcubes came four sides to a module, and were pluggable.

#

That's for photography; the flash served the same purpose as modern.

On a scale of 1 - 10, how wearable would you rate an arduino mega?

Are jumper cables capable of being permanent cables or no?

static delta Mar 23, 2018, 10:15 PM

#

@brave tendon you can solder them to your "things"

brave tendon Mar 23, 2018, 10:16 PM

#

I heard that male headers don’t connect permanently to female headers, is that true?

mortal edge Mar 23, 2018, 10:32 PM

#

@brave tendon what kind of jumper cables are you refering to?

brave tendon Mar 23, 2018, 10:32 PM

#

The standard premium ones sold on Adafruit’s site.

mortal edge Mar 23, 2018, 10:33 PM

#

correct. they do not connect permanently.

#

depending on your application, you can use them like permanent cables. or maybe semi-permanent is a better term.

#

i've done that. where i've got various modules (pi, sensors, etc) that all have 0.1" header pins, buried in a project.

#

i used those style cables to tie everything together and called it good

#

ok for sits-on-a-shelf like projects, but if you're trying to put these in orbit, then you might want something a little more permanent

static delta Mar 23, 2018, 10:38 PM

#

soldering them, they can work like any other wire. if you are intending to use them in headers, then no, it can be fine for some projects but as @mortal edge said, if you are creating something that is going to be remote and in production use, you want to use a permanent installation.

meager mirage Mar 24, 2018, 12:12 AM

#

The biggest issue I've run into when making the jumpers permanent is the fragility of the junction between the wire and connector (or solder joint if the connector end was clipped). The plastic coating of the wire is very inflexible and can't take a lot of bending particularly where the insulator has been cut. I completely switched to silicone wire instead.

brave tendon Mar 24, 2018, 3:36 AM

#

@meager mirage Yeah, I plan to buy some of those silicone wire rolls. They’re pretty cheap and fit my budget so I might as well try.

We bought a v3 Flora last year, and finally are getting around to trying it. Unfortunately it disconnects from USB as soon as we download the sketch in Arduino 1.8 IDE

#

Any ideas why this might be?

(tried windows 10 and Mac OS 10.13)

#

@fluid adder If you load a simple Blink example on it, does it blink? Not sure what you mean about it disconnecting immediately.

fluid adder Apr 8, 2018, 10:03 PM

#

It disconnects from the available devices when the sketch compiles, and isn’t available when the download starts. I’ll write it up and send it to the support email since that’s probably a better place

Improved heat management by opening a window and add copper heatspreaders , the original design have no vents and run hot as hell after a while . Weight improvement (from 420g to 195g) i barely feel im wearing it . Fit my face with comfort (foam frame)

somewhat a "hardware" hack

these HMD are cheap now (200$) but full of flaws , even if the display and tracking are as good a the last vive pro upgrade .

There is a saying RGB makes everything better

candid cosmos May 2, 2018, 7:11 PM

You need to check your local laws regarding adding lights to a motor vehicle. They probably restrict colors. flashing and brightness so that you don't get mistaken for emergency/fire/police vehicles and don't become a distraction to others on the road. Although, there should be some info in auto forums for aftermarket product installs/mods. Note that autos are usually 12v systems whereas arduino is 5v/3v and have to account for that.

#

but for wearables, there are direction signal backpacks, gloves, jackets, not too many mods on helmets because you don't want to compromise any built-in safety, GPS jackets, haptic feedback, rider communication systems...

@grim cypress There seems to be a recent surge in questions on the UBLOX GPS modules. Is there some school or curriculum that is promoting its use for projects? From what I have seen, it might take some sleuthing to get things sorted out to connect it to an arduino, maybe a little more difficult if for microbit. I don't know if it is similar to anything adafruit has to even start, maybe look in the adafruit forums or post in #help-with-radio. Good luck.

I plan on selling my WIP project, just had too little time and too little money. It’s a WIP Air Mag kit, has the EL lights, 9V or 3V powered, and the shoes. The shoes however requires work such as gutting the sole to place the electronics and restructuring the fabric to appear more realistic. Was planning on putting an Adafruit circuit to make it rechargeable and auto-lacing but ended up being too costly and time-inducing for me. Message me if you’re interested in finishing my project.

I'm guessing, as I don't entirely know what you mean by "sagging", but have you considered adding boning? There's plastic "boning" available that's used in corsets (albeit awful for corsets), but it could add some rigidity to the structure if that's what you're looking for.

canvas with a leather flap

the other bag is all canvas

but thats a backpack and I attach on the diag\anial with that

amber widget Jun 5, 2018, 7:50 PM

Ok, so I think part of the issue is that it has flaps on the end of the matrix bit, so it hangs instead of the clips being right next to the matrix

have you thought about adding grommets to the bag in specific places to have better mounting points?

That would work on canvas or leather

You could add loops to the top of the bit with the matrix in it, and then hook those loops over the carabiners as well to hold it closer, and then the webbing would simply sit there for now...

mint goblet Jun 5, 2018, 7:57 PM

#

the attach to the D rings that the strap is on, I am not sure if there is a better place?

amber widget Jun 5, 2018, 7:58 PM

#

Basically make two new loops but only for the top.

mint goblet Jun 5, 2018, 7:58 PM

#

the loop thing I did consider

amber widget Jun 5, 2018, 7:58 PM

#

Well if I couldn't do any of the other stuff we talked about, that's where I'd go with it

mint goblet Jun 5, 2018, 7:58 PM

#

I have 2 links on each loop for that

#

thank you for being a sounding bard

amber widget Jun 5, 2018, 7:59 PM

#

Seems like if you could attach the top corners of the matrix part of it where the D-rings are now, I don't think it would sag so much and the bottom connections could be left the same just to hold it down a little.

#

Yeah for sure 😃

mint goblet Jun 5, 2018, 8:00 PM

#

?

amber widget Jun 5, 2018, 8:00 PM

#

I was summing up what we already said, that wasn't anything new

#

I may have worded it badly

mint goblet Jun 5, 2018, 8:00 PM

#

I ushaly use the loops on the bottom to the straps that close the flap and the top ones to the shoulder strap

amber widget Jun 5, 2018, 8:01 PM

#

Right, but the matrix seems wide enough that if you put loops closer to the top corners of it, you could still attach them to the shoulder straps, and it would hold the matrix flat against the bag

#

Essentially it's a workaround to shortening the straps.

#

Add another mounting point instead of altering the current one.

#

But what I was saying, was that the bottom ones can be left as-is, I don't think they'd need to be changed.

mint goblet Jun 5, 2018, 8:02 PM

#

heem, not a bad idea

will coating conductive thread strands with fabric paint individually be sufficient insulation to braid them together? will the braid be able to flex and stuff without the coating cracking?

candid cosmos Jul 7, 2018, 4:44 PM

#

@potent valley You are probably better off using the flexible silicone coated insulated wire available at Adafruit. The problem with conductive thread when you try to coat them - like with nail polish at connections - the liquid may seep into the fibers to actually insulate the fibers/contact pad and break the connection. Fabric paint is a little thicker but like painting surfaces that move, the paint will eventually work its way loose and crack. If you've already made your project with conductive thread, you could splice in at the flex joints a braided real wire "jumper" set for durability and reliability. The auto parts store will have some silicone insulated hookup wire if you need to get your hands on some quicker than ordering. Good luck.

The Gemma may be fussy at times when you are trying to upload from the Arduino IDE. Check out the guide for tips https://learn.adafruit.com/introducing-gemma/introduction but the trick usually is to hit the reset button on the board at the right time so that the bootloader can communicate with the PC as it uploads the sketch. Also check in the IDE settings that adafruit Gemma is selected as the board and USBtinyISP is the programmer selected. Good luck.

That's a good question. I know the Teensy boards can emulate a variety of USB peripherals, but while the CPX can emulate a keyboard (https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-hid-keyboard) I'm guessing it also continues to emulate a storage device.

my probleme is only 12 on 16 leds are working... did you know what possibilby can go wrong? The board? the library?

#

thanks for your precious advices 😃

stark storm Jul 19, 2018, 6:53 PM

#

I can think of 4 things: one is that the code is configured for 12 LEDs (an easy thing to check). Another is that there might be a power problem: what power supply are you using? Another is that there's a bad connection between LED 12 and 13 – that's trickier to check, but gently pressing on those two (the last working one and the first non-working one) might shift things enough to make a temporary connection. The last is that one of the LEDs may have failed. If you think that's a possibility, try contacting AdaFruit support.

yes it is the RGBW NAtural Led

stark storm Jul 19, 2018, 7:03 PM

#

Oooh, good catch! I forgot those were out there.

amber widget Jul 19, 2018, 7:03 PM

#

The code is different for RGBW than RGB because of the extra bit needed to talk to the fourth LED in each pixel.

#

So since you're sending 3/4 of the number of bits you need, 3/4 of the LEDs work.

light wigeon Jul 19, 2018, 7:04 PM

#

🤔

amber widget Jul 19, 2018, 7:04 PM

#

For CircuitPython, you can add the fourth bit easily by changing the color tuple to (r, g, b, w), i.e. (255, 255, 255, 0). I don't know how to alter the code you're using though.

light wigeon Jul 19, 2018, 7:05 PM

#

well actually i wanted this first project to work and see all parameters one by one because at the moment i dont catch all the code language 😃

#

i even dont know yet how to change the color or frequency

#

for the moment i hace for exemple :

#

case 0: // Random sparkles - just one LED on at a time!
i = random(NUM_LEDS); // Choose a random pixel
pixels.setPixelColor(i, color); // Set it to current color
pixels.show(); // Refresh LED states
// Set same pixel to "off" color now but DON'T refresh...
// it stays on for now...both this and the next random
// pixel will be refreshed on the next pass.
pixels.setPixelColor(i, 0);
delay(10); // 10 millisecond delay

amber widget Jul 19, 2018, 7:06 PM

#

I don't know Arduino, so I can't tell you how to alter the code to work with your rings, but from what I can tell the project is designed to work with RGB rings. So something would need to change.

Multitasking in microcontrollers is an interesting exercise. I have one implementation of a 24-channel phase control dimmer in a Teensy 2, and I'm working on another one to draw text on a CRT by decoding the old Hershey vector font, transforming the coördinates, queueing them into a buffer, and then clocking them out the DAC pins at a regular rate. It's kind of hairy code, but it seems to be working.

#

@candid cosmos thanks. i actually start by the project on the LEARN section. as im started im not aware yet what is up to date and what need some extensions... but if i need something i might ask you... verry soon :p

stark storm Jul 20, 2018, 4:38 PM

#

When multitasking, I like to factor out repeated stuff like the call to millis() and subtraction. So at the beginning of loop(), I'll have something like unsigned long curtime = millis(); and unsigned long schedtime; for each thing I want to schedule.

#

Then a simple test for curtime > schedtime will detect when it's time to run something, and in that block, I'll use schedtime = curtime + interval; to reset the time for the next time around.

light wigeon Jul 20, 2018, 4:41 PM

😄

candid cosmos Jul 20, 2018, 6:05 PM

#

When you get into programming neopixels, it helps to get into the mindset/paradigm of what a stop motion animator does. You have to structure your sketch like it is working frame by frame. Because the Arduino is essentially a simple one-tasker and takes some time to execute a command, if you are making the lights go through a rainbow fade it may never get around to sensing your switch to change the animation or move the servo. You use the big loop to go frame by frame - maybe calculate a color change, set the pixel color, sense switch, move servo a tiny bit and move on to next step, all hoping that you can squeeze in all that to make the animation look nice and not awkward.

stark storm Jul 20, 2018, 6:39 PM

#

Yup, that's how my Hershey font code works. Each loop, it checks to see if it's time to emit a sample via the DACs, then it checks to see if it's in the middle of drawing a segment, if so, it calculates the next position, if not, it looks for the next segment, or the next character.

candid cosmos Jul 20, 2018, 6:55 PM

All that ties in well with the "state machine" concept...and switch debouncing. Some basic concepts that are never taught to beginner programmers...like flowcharting to better understand what you are doing or attempting to do.

Hi everyone, I would like to create some workshops with wearables to teach those who don't usually use technology in this way how easy it can be to get going. I have a gemma v2 from the sequin starterpack but to be honest, uploading from my macbook to this board is touch and go and not something I feel would give beginners confidence - which board would be the best to start with? I am looking for 1. small board 2. easy to program (makecode looks good for this I guess, but easy upload?) 3. cheap 4. low power requirement. what do you think?

stark storm Aug 3, 2018, 1:34 PM

#

I'd suggest a Gemma M0. The genuine USB support makes the loading process much smoother, it's more powerful, and isn't expensive. I've never used MakeCode, but it's easy enough to program with Mu (which handles the upload for you). I taught a class of kids using Mu, and they got the hang of it pretty quickly.

candid cosmos Aug 3, 2018, 1:48 PM

Hi @light wigeon, welcome. For beginners to coding, electronics, and wearables, my recommendation would be the Adafruit Circuit Playground Express board.(CPX). It may be a bit more expensive but worth it in terms of ease of use, has sensors embedded in it that you would want later on and the learning "ecosystem" that exists for it. In actuality, small tiny boards and conductive thread are really for more advanced users who know how quirky they can be and can use them without getting frustrated. The added cost is more of an investment that pays back in a better starter experience. Most of the time I just run the electronics off of a battery pack with standard AA or AAA batteries . For wearables, using the CPX means users can jump right in and create that LED blinking garment which responds to sound, light, touch, or temperature without needing to buy and solder on additional components. Browse through the Learn section on the Adafruit site to get an idea of the vast wearable projects you can do as well as all the starter tutorials. Maybe you can get some sponsorship for your workshop, there are educator packs that are sold by Adafruit. Good luck.

light wigeon Aug 3, 2018, 2:31 PM

#

Thanks so much @stark storm and @candid cosmos I will try mu, and have ordered a CPX to see if I can make a good experience with it. Will definitely have a look at the educator packs too.

Hi Gang!

#

Is there a page or some tutorial where i can find a way to learn how to code the LED for NEOPIXEL RGBW with a GEMMA v2?

#

Im trying many thing and i still have the demo code working... i really would like to know how to control each parameter and do my own animation.

#

thanks

#

and to continue, can someon explain me how to fix this kind of problem: whiteOverRainbow' was not declared in this scope! i get a lot of those lately

candid cosmos Aug 6, 2018, 5:59 PM

#

@light wigeon In arduino, coding for RGBW neopixels is the same for RGB neopixels except there is an extra parameter in the color statement (R,G,B,W) and the specification in the setup line.

#

the error message you get probably points to a whiteOverRainbow function not properly coded or if that variable is not defined for the loop it is used in.

Just a quick check, there's a way to wire up people as capacitive touch sensors, right?

#

The problem I'm trying to solve is having people high-fiving or bumping butts or otherwise bouncing off each other while dancing act as a trigger signal.

#

Or would accelerometers be a better idea?

stark storm Aug 9, 2018, 9:37 PM

#

My guess is that it's theoretically possible, but would require some tweaking of thresholds, as different people have different capacitances. Further, if they're bumping each other with clothed parts of their bodies, it may not be workable.

ancient flame Aug 9, 2018, 9:38 PM

i have a stupid question, i can connect strands of neopixels together via jst connectors to power them all via 1 5v trinket pro/power source with a powerboost correct, provided theres not too much distance and im not using a crazy amount of neopixels,?

candid cosmos Sep 14, 2018, 4:23 PM

#

@queen inlet I don't use powerboost modules so I don't know if your setup will last long or the neopixel load at full brightness will tax the powerboost but basic wiring is ok with jst connectors if you want to put in a break. They will be more resistant to pulling apart than other connectors available and used in wearables. Just note that if you have factory installed wires and jst connector already on the neopixel strip, they may be wired up to the input or output end of the strip and you will have to connect to the correct end for things to work. Good luck.

Hello Adafruit Discord community! I am working on the mad scientist goggles project as sold on the Adafruit website. I am trying to recreate a similar look to the DJ Rezz. In addition to the kit, I ordered an addition a pair of 24 x RGBW in order to create two circles of light over each eye, one 16 and one 24. A few starting questions:
I'm totally new at this so I am not sure how to wire the 24 neopixel rings to the smaller 16 ones.

Can I use the trinket that came with it to program all four neopixel rings? I also ordered a Gemma v2 to have for other projects so would this be better suited to handle this instead?

Similarly will the 3.7v battery be enough to power them?

@lime kite To get familiar with neopixels, look at the following guides https://learn.adafruit.com/adafruit-neopixel-uberguide/the-magic-of-neopixels , https://learn.adafruit.com/sipping-power-with-neopixels?view=all and the guide for your goggles https://learn.adafruit.com/kaleidoscope-eyes-neopixel-led-goggles-trinket-gemma A Trinket and a Gemma V2 are essentially the same under the hood. So here are a few things: The googles kit may come with RGB neopixels and not RGBW and when the different kinds are both connected together may produce some unexpected colors, flashes, no lights. What you can try is to connect each kind to a different pin and code accordingly - chaining the rings together data out to data in to act as one long strip would not be good with the different kinds. The Trinket/Gemma should be able to drive such a relatively small amount of neopixels - under 100. Set the brightness to low to start out with to see how the battery can handle the load - usually when neopixels all turn red or dim, they are underpowered and when your animation freezes up.... When you get all your parts, come back and we can guide you along.

I'm planning to make twinkling Halloween dresses for my girls and the idea of exposed conductive thread between the pixels has me nervous. In fact I'm convinced i'm going to either ruin some components or have a battery fire the first time they sit down... Has anyone had luck sewing enameled wire? I want to put 20-30 pixels on each dress and want the fabric to flow as naturally as possible all things considered.

candid cosmos Oct 2, 2018, 3:10 AM

@sand willow You are better off using silicone insulated wire https://www.adafruit.com/product/3164 Enameled wire is kinda stiff and brittlely when flexed too much. You may need to learn to solder but that guarantees less of a headache when trying to connect and troubleshoot the entire setup. Btw, you could probably wind a lower bobbin with enamel wire on a sewing machine and topstitch it with regular thread. You wouldn't pass that through the needle if you wanted to experiment. Good luck.

radiant bay Oct 3, 2018, 10:24 PM

#

@sand willow Id trust your intuition and second the suggestion from @candid cosmos to use wire. I’ve used it for a maximum 25 pixels and seen significant drops and inconsistencies in performance to the point where I’ve changed direction on using it to keep a piece alive. The thread is fantastic and exciting for small projects but I am in love with that silicone wire. The thread can also be a pain to sew, to be honest. The 30awg is super tiny and amazing and you might be able to weave it through mesh fabric like thread.

#

@candid cosmos i dont think I’ve used enameled wire, tbh, unless I’m totally blanking on it. If there’s an issue of being brittle, it would probably also work well to keep it out of the machine and sew a zigzag stick over it to make a channel - i think Becky did this with the chameleon scarf.

@radiant bay magnet wire - enameled wire - getting brittle might not be the best term to describe it, it's extremely thin - from motor windings, wirewrapping to transformer thickness and is useful in some applications like those eyelash LEDs and covering with makeup.

@lilac axle I'll say anything is wearable - making it wearable is just a means of mounting the hardware... But bluetooth, wifi, radio, and cellular modules can be added on to arduino boards like FLORA or an UNO R3. If you are concerned about size, they are all pretty small but you have some that are built into the board like the ESP8266 or the Adafruit Feathers and the add-on wings. Depending on the project, you will find that you might need a controller app on a smartphone or some kind of connection to a "cloud" service like for IoT(Internet of Things). Good luck.

I have some basic BLE questions. I'd like to get started on a project that uses BLE, but I have very limited needs. I really only want something that can detect IF a BLE connection is made (GAP?), and I don't want to send any data, but just have an ACK of the connection (1 I/O pin?). I'm using the CPX now, so not sure if Adafruit Bluefruit LE UART Friend would be the way to go (if I could use it with the CPX), or if something like the Adafruit Feather 32u4 Bluefruit LE is the way to go. I really like having the speaker on the CPX to use, and the LED's aren't bad. Or is there some other kind of "beacon" I can use to detect my phone? I've read the new "How to Choose a uC" that was just put out, and I know it states "If you want wireless communication between microcontrollers, you almost certainly do not want BLE.", but that's not what I want to do. I only want to use BLE to detect the presence of paired connection. Comments? Thanks in advance.

@livid basin you may want to look at the new CircuitPython Library https://github.com/adafruit/Adafruit_CircuitPython_BluefruitSPI that should supports a BluefruitSPI Friend.. I have been playing with one attached to am ItsyBitsy M0 Espress. It should work with a CPX as well as long as the SPI pins are available. I assume you can do the same type of thing via Arduino with the BluefruitSPI friend or UART Friend but I have not tried. You can also use the Feather nRF52832 https://www.adafruit.com/product/3406 which has BLE support in Arduino and is "comming soon" via CircuitPython.

@grim night Thanks...I'm getting confused. I posted this question on the forum as well and was told it is not possible. Also, I'm seeing that the SPI pins are not available on the CPX. I haven't tried this yet, as I have not tinkered with BLE myself. It seems like it should be possible if the uC device acting as a peripheral can 1) initially get paired to a central device (cell phone), 2) can send out advertising packets after being paired and 3) acknowledge that the pairing was established. Still trying to see what the best solution for this simple task is.

I am not sure of the status of BLE on the ESP32 in Arduino. I have not tried it. It is not yet supported in CurcuitPython and I think is still a work in progress on Micropython.

#

@grim night Ok, so it looks like the BLE modules, like the Adafruit Bluefruit LE SPI Friend do not have any I/O or "connection estabilished" capability other than the SPI interface. So I would have to go with the Adafruit Feather nRF52 Bluefruit LE to act as a detection device.

grim night Nov 12, 2018, 3:11 PM

#

Cant you just set a GPIO pin yourself to report the status?

#

that is query the BLE device for connected status and then set a GPIO pin on your board.

#

Just to clarify, you need a microcontroller and the BLE SPI Friend or one fo the feathers with both on one board.

livid basin Nov 12, 2018, 3:19 PM

#

Yes. Seems like the way to go. Still not sure what BLE device to use....guess I just need to pick one. Looks like $9 for a dev board
ESP32 WiFi-BT-BLE MCU Module / ESP-WROOM-32 , up to $25 or more for a feather.

grim night Nov 12, 2018, 3:22 PM

#

what development environment are you using? For the ESP32 would you use the ESPRESSIF SDK or were you planning to use Arduino?

#

There are a lot of option -- same for the nrf52832 and also for the nrf52840 chips -- like this $10 nrf52840 "dongle" https://www.mouser.com/ProductDetail/Nordic-Semiconductor/nRF52840-Dongle?qs=gTYE2QTfZfTbdrOaMHWEZg%3D%3D&gclid=CjwKCAiA5qTfBRAoEiwAwQy-6TMMl1icHtONr48lPJdfF7bjHTyLB4DI_QmEH3TU-FDR0d2qNlR4JxoCQI0QAvD_BwE

#

or this 52832 board https://www.espruino.com/MDBT42Q

If you are familiar with javascript, the espruino may be a simple way to go.

@light wigeon https://learn.adafruit.com/adafruit-gemma-m0/windows-driver-installation It looks like windows 10 doesn't need drivers but try changing the port you are connecting to, USB3.0 has affected other things in the past, you might need a usb2.0 hub as a passthru if you do not have older ports on your PC. Good luck.

I working with the Flora, Gemma and the Playground Express with no issues at the end. I hope the CRICKIT will be delivered in some days todo more crazy stuff. It was a little bit of nightmare on W7 Pro to get it working under A-IDE 1.8.7. After 2 hours i got it. Stupid driver handling on Windows. It's a genewric issue to life with.

I came here to find some stuff and ideas and i hope i will find some. 1st i do that for my kids in the dark light time of the year and it works amazing.
Normally i work for tasmota on github. Writing diver and help people as admin on discord.
I also working on a wearable human monitoring device with muscle sensor, heartrate and oxygen value, GPS and multigas sensor. All hardware is in house and it needs time but the playground classic is my favor in this. I have a sonoff sv too with wifi on board. So have to see to get wifi on the classic going. For that i need some ideas or a hint which hardware can be used.

BTW: i saw the Adafruit Circuit Playground Express Enclosure. Which is a very good idea to isolate the electronics a bit. Very well done Adafruit! And now one for the Flora and Gemma, then Adafruit is a master of design 😃

I have an idea for a project that would involve raising/lowering layers of fabric in a costume. Any ideas? Maybe a small, wearable motor?

woeful comet Nov 22, 2018, 6:21 AM

#

Maybe I just need to do some experiments with a micro servo. Hmm.

candid cosmos Nov 22, 2018, 5:48 PM

#

@woeful comet You are probably crossing into the realm of robotics when you develop your system. Fabric can be heavy and it drags along or gets caught up when it moves. Know that if you are using a microcontroller board you will have to make special consideration for driving and powering motors. One of the adafruit boards paired with a CRICKIT would work nicely. Also think about how to use pulleys or screw drives for your actuators. Hobby servos are strong but not really suited for heavy lifting. Did you have in mind moving a hoop of a garment? I've seen use of salvaged electric drill motors to serve as a winch in some costume expanding wings. Good luck.

#

@next zephyr Welcome! Be sure to look through the Adafruit Learn section on some great projects. Their blog is also great for browsing to get ideas, especially wearables(not to mention some of the things I've got mentioned there...)

woeful comet Nov 22, 2018, 7:32 PM

#

@candid cosmos Thanks! Good food for thought. I'm still brainstorming so I'm not sure what the final might look like, but I was imagining raising and lowering sections of fabric like a stage curtain. You have some good thoughts for me to chew on though. The crickit seems kinda big and I was hoping to keep the tech as small as possible, but I actually have a crickit and haven't played with it yet so maybe this is a good reason to give it a try. crickit

stark storm Nov 22, 2018, 7:43 PM

#

It might make sense to do just as you said: do some experiments with a micro servo. It's not much investment, and you'll learn the sort of things servos can do, and how to work with them. Then you can consider scaling up to bigger servos or motors like @candid cosmos describes, if needed for the effect you want.

candid cosmos Nov 22, 2018, 9:15 PM

@woeful comet You could take a look at this https://twitter.com/sophywong/status/1017301647855214592 She also does work in costuming so you might be able to ask @indigo fern for ideas.

@candid cosmos thanks for your advies. I had read some but found nothing new for me. Have to say that i have more then 30 years of industrial coding experinece (Port of Rotterdam (main coder), Satelite communication, Chip production machines, Food industry, Medical industry, robotics, water barrier technics (deich, dijk) and so on...). But i will have an eye on it to see some new things.

@drifting sorrel Badly enough we can't get all new hardware from Adafruit in our local store. Ha, ha, they say Ada has to edit here web page (the one from the local store) so new things can be ordered. Fools, that can't be possible they think we are stupid here. I had written an eMail to Ada and the answer was foolish too, have to say it because they did not understand what's going on. So the sales team is not the lightes one i think. Sorry to say but i'm not alone with that...

But in any case it is good to have hardware that works and a good community that exsists here!

@grand owl sorry but I think autocorrect got to your comment. If you think you have usb3.0 issues, sometimes it helps to connect through a USB 2.0 hub to the computer. Mac stuff is more sensitive or has more issues with using USB 3.0 on these microcontrollers.

@next zephyr Thanks for stopping by. I usually check all the channels but I originally suggested this as a locale that would welcome others just getting into electronics or where other categories were just too technical. Wearables is a pretty open category which I guess a lot of my projects fall into. I'm trying to bridge the creative types with the new tech.

@candid cosmos possible you can help because i'm a little bit irritated about the information from learn.adafruit. Different pages and different defines. Which one is the right one?

Some little question i have:

Which is the external NeoPixel pin number on the Playground Express. I think it is A1 but did not fimd it on learn.adafruit

Which pin number is it? 6 or 8 or?

I would use the seeaw library for the crickit and that are two questions:

1. when using not seesaw lib the A1 on playground is the neo pixel output. Is that pin 6 or 8? Looks like my 1st question at all.
1. when using seesaw the the solderpoint under the crickit has to be changed to 'ss' but first cut the A1 connection. Then pin number 10 should be used. Is that the right one for seesaw?

I found some hints on three different locations under learn adafruit, but no place where all in one is defined. Something that can possibly done for the furure?

I ask only because i have used the different example but nothing works. The rgb leds are working on the flora with external use, so the leds are ok.
The internal rgb leds from the playground express are working too? So i'm in the define war 😉

"If you have a Circuit Playground Crickit then the NeoPixels are driven by the Circuit Playground A1 pad by default. This way you can use the MakeCode emulator and built in Circuit Playground CircuitPython library. However, if you want, you can cut the jumper underneath the Crickit and solder closed the ss pad so that the seesaw chip controls the NeoPixels (for advanced hackers only)."

@robust aurora
1st thank you for your answer.
I used A1/D6 defined as: #define PIN 6

But it won't work so that's a little bit strange. On a Flora all is working. Will take the playground express away from the crickit board and test it standalone.

About pin 8 you are right:
#define CPLAY_NEOPIXELPIN 8

I don't code in makecode i use arduino ide and notpad++. Arduino ide for debug and download only ;-)

Ok will do the test again and report back. Possible i have overseen one thing.

@next zephyr I don't have a Crikit so I can only point you to the learn guide. I think using Arduino programming may be a little more involved, especially for a beginner since the focus is to wean off of Arduino and go to CircuitPython which is developed to work well with it. Even with the Circuit Playground Classic and it's arduino library, pin names had to be referred to as board.A1 The Crickit guide has a step to install the Seesaw(I2C chip) arduino library which you may not have done. Feel free to ask in #help-with-projects for others to chime in.

next zephyr Nov 29, 2018, 11:07 PM

#

@candid cosmos Thanks for your answer.
BTW: i'm not a beginner at all. I know about the difference in the pin naming. At the end i had read the *.h files and it was clear after all.
The issue itself was different because the learn sites name things sometimes so and sometimes so. I will write it down and send it to the guys who manage that stuff.
After some tests i took what i think it was right and it was working at all.
The other point is the pin 6 is overall the same it likes. So next step was to use and change the sample in Arduino to get it work with seesaw.
BTW: i soldered a switch for the solderpin A1/ss under the crickit board so that i can switch from one part to the other when it is needed.
Last point is the installation process. I do that by copy the needed things into the Arduino folder and it works everytime. The Seesaw lib was already installed because i needed servo and motor tests. So as i said i'm not a beginner in all that. I working on the esp8266 core to fix things and i'm writing drivers for the alternative iTead's sonoff firmware for Tasmota on github. You can find me there as a admin with the same avatar name ;-)

@verbal hatch Nice. You'll get hooked on adding neopixels to everything. The trick to videoing or taking pictures of LEDs or neopixels in action is to turn down the brightness to very low. The camera will thank you for that. You can then turn the brightness up for regular use after filming your demo reel.

verbal hatch Dec 6, 2018, 4:10 PM

#

I think at one point in filming, caitlinsdad, I set ISO to 100 on my Samsung J7. I'll try to do more with an oldie iPhone 6 that we only use for videoing now and on a DJI Osmo mobile. Yes, neopixels are not easy especially with sparkles in the code. I need to find a way to make an RGB LED extension for block coding the BrainPad by Gus Issa at GHI electronics. Do you know anything about adding extensions for non -Adafruit Cortex M (x) boards? I think his is M4. Thx. (or where I might go or who I might ask to get info . on this, like the "light" extension on Trinket M0)

candid cosmos Dec 6, 2018, 6:22 PM

@verbal hatch That behind the scenes coding stuff is beyond me. You might want to wander into the #help-with-makecode channel and ask to see if MakeCode can be used in a similar fashion or if the mechanics for block code can be applied. Good luck.

verbal hatch Dec 6, 2018, 8:08 PM

Looks possible, @candid cosmos, see the latest post at MakeCode. I too know nothing about the programming part but kids just love LED light shows and learning how to change them up with instant feedback. For Trinket M0 this coding with MakeCode is so much easier than Arduino which is easy enough for teens. We'll see how this progresses. BTW, how old is Caitlin? We are working up projects based on Music and wearable electronic fashion , especially to connect with girls. I'll have more designs to feature all this as things progress in the new year...unfortunately, Adafruit seems to be out of the Trinket M0, my new go-to board for block coding with MakeCode. I have 3 but now am hesitant to give them away in kits. I did ask Adafruit to contact me when the board comes back in stock..let's hope soon.

candid cosmos Dec 6, 2018, 10:58 PM

@verbal hatch The kid is in college already...time flies. Hmmm, some places you might want to look for ideas or inspiration for wearables and wearable/music is instructables, adafruit blog and Learn sections. Smore magazine(new mag geared to ramp up girl's interest in STEM), Hackspace magazine(free pdf download) or even ask @indigo fern , she just made the cat meow glove. There was a youtube video of Ariana Grande using the glove music controller that was developed by Imogen Heap which was pretty cool. I guess further down the road with more advanced boards you can do all the NeoTrellis music stuff that John Park is working on for his show. I have found the Circuit Playground Express board is great for making since a lot of the basic sensors you want to use are built in and don't have to deal with the complication of adding them on to something like a bare Trinket.

but when they are older i think it will be the next step to go to java or c/c++. These are the most used languages in the industry and badly enough we all have to live with it. Before that all changes hundreds of years have to go i think...
For now and my last 30 years in industrial coding and project mangament i have seen so many things that went wrong and good things too in different coding languages. So lets hope that people and the industry wakes up fast to get a good and well designed standard so that everyone in the world can contribute to the community. And when these MakeCode is a way to it then be it. We need only a way from that to the next standard i think...

I'll make a video of this and the code for it; not especially complex or novel but I flatter myself that this is a contribution to the community because the coding to drive the dual neopixel rings on the hat was done entirely off-line but using a $79 Chormebook (E-Bay) and an $8,95 Adafruit Trinket M0 ; wearable with a $5.88 5volt battery pack. It will take me several minutes to make up the vid. and give links to parts. MakeCode used for programming. Chromebooks are said to work only on-line with the Chrome OS. ; proven here not true with MakeCode.

So all CPX are mounted on the Crickit's and nicely coded in C++. All works fine with my own new test program. Test is the real code, LIPO's with adafruit lipo loader and some clear instructions for loading. Next step is some toys for kids in wood for them.

I'm guessing you could simply digitize the audio and write it to the SD card, but I don't know enough about the keyboard to suggest more direct methods. I'm surprised a roll-up keyboard even has a hard drive.

I used the term "hard drive" loosely , madbodger. I mean , as opposed to a removable micro sd card or some such. It just has a 'record' function with a ticking metronome that is almost as annoying as my piano playing !

@alpine hollow Definitely not, but just grab a cheap gps module online 😃 Screens are fairly cheap as well, depends on what you want to build

#

*What are you trying to do?

native loom Dec 21, 2018, 1:38 PM

#

To take the recorded output tune, which can be recorded by pushing the 'record' button on the electronic keyboard and which I show in the vid. can be played back via wires into the remote speakers (ear rings) ; record that digital output onto an SD card ,which the read/write module of the card is plugged into the 170 tie hole solderless breadboard shown attached to the mannequin's back (could be 400 tie hole). This then makes the music portable using 5 volt battery pack. Hence the neopixel pendant and music are wearable. Just wondering what code or system could be used to program the Trinket M0 on the breadboard to record the incoming signal from the keyboard's recorded output ?

stark storm Dec 21, 2018, 2:34 PM

#

It's probably worth looking at whether the M0's ADC is fast enough to do so (I don't know offhand).

Playground Express:
found some funny code about sound by notes. Good idea so far. I'm a big fan of Lordi and Classical Music. Why use notes only when you can use a MP3 Player.

A while back i wrote/updated a MP3 Player driver for the iTead's sonoff devices for the tasmota firmware to be more conform and that peace is working very well (xdrv_14_mp3.ino). You can wakeup with music or add music or sounds to actions via web, mqtt, HA and other inputs.

So why not use a Flora or a CPX?
Easy...DFRobot has a tiny little board that can work between 3.0 and 5V and has a serial in and output, Mono and Stereo speaker output and a DAC output.
Had done some little test with serial out on the CPX and the serial input only on that tiny player. It works..
Connected the two tiny Adafruit speaker on it (ID 1669) and voila, stereo sound. Yeah, no hifi but that is the next step in a backpack, ha, ha.
So now some sensors to the CPX (GPS, light, Heart sensor, XYZ, and so on). The heart sensor is funny because our heart reacts on moods from our self. I know because after my 4th heart attack in 2017 march 30, many things and me are very changed. So i copied some music on the SD card for happy mood, mid mood amd sad mood. Yeah the sad mood happens when you had 4 HA's. Unbelievable it works. While 24 hours i had the senosors connected and were gone trough the day and in 90% the sensor was right after 20 times fixing the code, ha, ha. Mood tracker..
Next step will be the 100% wearable with sound and mood light (led's on board).
Bad thing is we can't get the new case from adafruit here. That transparent one for the Curcuit Playground Express.
Ada ID 3915
The Lipo (in a small lipo safe case),the player and the breakoutboard forr the heart sensor can be put in a pocket.
the speaker i had placed a little top and front of the little holes of the shoulders.
In that project i will put a lot more work in to get it perfect. Possible i will publish it on my web page so everyone can do it's own.

Hey all, I've been looking into buying or making a device with the form factor of a wrist band or wrist watch that can communicate over bluetooth to a PC and can send customizable keystrokes when buttons are pressed.

#

Does something like this exist already? If not, what's a good way of going about getting parts that would compliment this form factor? I looked at the feather but it's rather large for what I'm wanting to do

#

I also realize I need to power the thing somehow. What's a good way to power something using bluetooth compactly?

#

I guess I'm asking for recommendations on two things:

A small micro controller board capable of communicating over Bluetooth and is low-power
A way of powering the device in such a way so that it's not bulky, preferably self-containable

#

I have soldering equipment, a 3D printer, access to a laser cutter, and access to a mill, and I'm going to design the wrist... thing in Fusion.

The Nordic PCA10059 dongle is even smaller, but you'd have more work to do rolling your own software. If the software was careful to do power management, you could power it with a coin cell.

@fair needle You should look into one of the Feather boards with BLE. They are small enough for wearables and you don't need to wire up an external module to the Flora. You would also be able to add on the Feather wing accessory boards for things like a small display or LED matrix.

I think your idea of LEDs and diffusers is likely more practical for that use. You could also use electroluminescent panels (which are flexible), but they require high voltage which you may not want in a costume.

I think in general if you are considering using solvents to clean the entire garment, your own setup would be more expensive than a trip to the dry cleaners. A lot of wearable electronics are embedded in costumes and the materials or finishes on them may not tolerate the use of solvents, even a weak solution of rubbing alcohol. Soap and water probably work best to get out playa mud and dust.

I could just use a normal sized ROM

Right. For illustration, here's a nice little computer built out of through-hole DIP format chips in a credit card form factor http://www.sunrise-ev.com//membershipcard.htm

Interesting

#

I could just go full on surface mounting

Try to make the computer a bit bigger then a credit card

That should be completely doable, and would probably fit on a single board. I did a quick look around and Zilog still makes Z80 chips, and offers one in a 44-pin PLCC just 16.5mm on a side.
