Or one half

lost condor
#

If you want it to go eye-blinding, there's a setBrightness(64) in setup() you can change

#

Change it to 0-255

#

Yep, I need to fix the math, hang on

indigo jetty
#

Let's see what this baby can do!

lost condor
#

The startup pattern and second pattern shold be the "best" looking

#

Second should be stripes

#

Well, wavesish

#

If it's weird and blue, that's the wrong direction

indigo jetty
#

I hadn't commented out glitter

#

Just did there

#

Looking much more patterny

lost condor
#

Yeah, meant to mention that

indigo jetty
#

let me add a serial print for the pattern name

#

I see you have a nice getName method ๐Ÿ˜ƒ

lost condor
#

Yep. ๐Ÿ˜„

#

It uses a four char buffer because of display size. ๐Ÿ˜„

#

Generating the new config, hang on

indigo jetty
#

SEcond one seems to be VERT unless my encoder is skipping

lost condor
#

That should be right

#

Drat paste is too long for in here.

#

That should fix the center

#

Since there are n-1 spaces between n objects.

#

(cough)

#

I guess I need to make it more modular for controls and displays, huh.

#

I have a single button interface as well for the hat. Quick press changes the pattern, long press toggles glitter.

indigo jetty
#

thats a cool idea

#

just trying now

#

I was worried there for a minute it stopped working just a dodgy connection to the power supply

lost condor
#

Yeah, my heart always skips a beat when that happens

#

Mainly because I don't want to solder all that again.

indigo jetty
#

ESP8266 has no hardware SPI pins, but it seems to be keeping up fine

#

(FASTLED compains)

lost condor
#

Oh, heh. It probably complains because it doesn't recognize the hardware

indigo jetty
#

yeah thats perfect!

lost condor
#

Awesome!

#

It's probably reverting to the slowest version of everything. Not sure how smooth it is for you

#

But, still, glad it works

indigo jetty
#

its pretty smooth

lost condor
#

It runs at >60fps on my trinket. ๐Ÿ˜„

indigo jetty
#

The esp8266 does Wifi stuff inbetween loops and I thought that would impact but it seems to be fine

lost condor
#

But FastLED is super aptimized for AVR

indigo jetty
#

I dont notice anyhting

lost condor
#

Cool

#

APTIMIZED

indigo jetty
#

Let me very slowly upload to GFYcat or something

lost condor
#

Apparently I'm a minnesotan

#

Cool

indigo jetty
#

I barely even now Miinesota (sp?) is a place

#

know

#

This is one of the examples that came with fast led that I uploaded earlier

lost condor
#

Neat

#

My patterns are slightly less optimized than that one because they are designed to run on an arbitrarily shaped display

#

So the pattern render function takes the x,y,r,and theta of the pixel

#

When you have a square, you can skip a lot of that

#

Though, you can still see some rounding errors in that gif that my technique avoids (at the expense of storage space)

#

The rounding errors look like "flickering"

#

Looks like the only one that shouldn't work is the audio burst pattern, but that's OK because it'll take some doing to get a mic hooked up with that 1v analog pin

indigo jetty
#

Challenge accepted ๐Ÿ˜›

#

I may aswell try it

#

just to see

#

but ya the range is surely terrible

lost condor
#

I assigned row and column to "ring" and "ring_pos" respectively for each LED

indigo jetty
#

Thanks so much for the help

lost condor
#

So I think it'll just end up looking like a big bar graph

indigo jetty
#

I didnt know what I was going to go for the patterns

lost condor
#

Glad to be of help. If I may suggest, try the "clouds" pattern with the "rainbow" palette.

#

That's my favorite ambient display

indigo jetty
#

I think i might mess around with the encoder code

lost condor
#

It's like a tie dye lava lamp

indigo jetty
#

so that it changes with a spin

#

and pressing the button switches between the encoder being for pattern or pallete

lost condor
#

Yeah. Or, you know, use the wifi. ๐Ÿ˜„

indigo jetty
#

I'd love to ๐Ÿ˜›

#

but i think doing anything that listens for connections will mess up the animations

lost condor
#

So, the nice thing about these animations is they're all time based

#

So while the frame rate may slow, the animation will still be accurate

indigo jetty
#

very interesting!

#

must play around with it so

lost condor
#

And if you use MQTT, then no need to listen for connections

#

just a poll here and there

indigo jetty
#

my end goal for this is going to make a front end hosted on a server that communicates with the ESP8266, probably via MQTT ok where you can draw on it

lost condor
#

(well, every loop)

#

Neat

indigo jetty
#

I threw it in the frame there just to see what it looks like

#

(although I'll probably use a white frame)

lost condor
#

Nice!

#

That's ROUT or RIN

#

(Radial Out, Radial In)

#

New as of last week, really like how they look.

#

Going to add the rectangular code generation to my pregen script now.

indigo jetty
#

Yeah the are awesome

#

They#

#

I owe you some consultation some time anyways! I have moderate esp8266 knowledge and not a lot else whatever that's worth to you ๐Ÿ˜‚

lost condor
#

It looks like you're getting some flicker there

#

I think you mentioned you weren't using a logic shifter

indigo jetty
#

I think it looks better than that IRL

lost condor
#

OK

#

As long as you're happy with it. ๐Ÿ˜„

indigo jetty
#

I can try a level shifter when I'm working on it again

lost condor
#

Thanks for the catch with the #include. I was stuck in dynamic code land I guess.

#

But yeah, glad the math worked out (and it only took two tries) ๐Ÿ˜„

#

Well three, if you count the one that I caught ahead of time.

indigo jetty
#

After I'm finished making the project I need to make a video for it

#

I have hours and hours and hours of footage

#

I dont know what I'm going to do with it

#

I normally make videos on small projects!

lost condor
#

I need to start working on my learn guide for my project too

viral spruce
#

How's everyone's friday eve. going?

#

(depending on what timezone you're in)

lost condor
#

The usual

indigo jetty
#

It is almost 4am

lost condor
#

Taking care of all the stuff I haven't had time for this week

indigo jetty
#

Tomorrow Brian is going to pay for today's brians mistakes

lost condor
#

Cleaning house and organizing code. ๐Ÿ˜„

#

Man, what has tomorrow Brian ever done for you, really?

#

All he ever does is make you feel guilty about today

indigo jetty
#

Nothing yet anyways

#

I would have liked to have finished the LED matrix but I'm out of Neopixels

#

I gave the left over ones from the one I bought to a buddy at work so I wont get them til Monday

#

(I broke 3 of them)

lost condor
#

Yuck, that sucks

indigo jetty
#

Ah its ok

#

I need to release a youtube video this weekend anyways

#

I havent released one in about a month

#

I dug this bad boy out of storage there, I got a new soldering wand for it

#

I bought it from China nearly 10 years ago now

polar wraith
#

Aaaaaah! Dozed off in an awkward position and woke up with a cramping right hamstring....

indigo jetty
#

Not a good way to wake up!

stuck moth
#

@indigo jetty and @lost condor seeing you two work together makes me so happy we made this discord. ๐Ÿ˜ƒ

lost condor
#

Haha

#

I'm just happy to have people to geek out with

#

My daughter and I just adapted the tuba code to her Uke as well

#

It needs a better name than "RGB Sousaphone" because it's rather general purpose.

stuck moth
#

@lost condor I can't wait to see claire on the show and tell more. ๐Ÿ˜ƒ

#

names are hard too

#

the testing software I did is still private because we haven't settled on a name

lost condor
#

There are two hard problems in programming. Naming things, cache invalidation, and off-by-one errors.

stuck moth
#

๐Ÿ˜„

indigo jetty
#

@stuck moth probably not as happy as me about it!

indigo jetty
#

@lost condor i think that project being called Rgb sousaphone is right, but I think you could extract the led stuff into a library and name that something else

#

Maybe "LED Smart Patterns" or LSP for short

#

The only thing I'm unsure about is how to pass the config in

#

Also I think you are right about flickering, it seems to flicker the further away from the psu it goes so my gut is it's power related

#

Starting the vcc at the center of the matrix will hopefully help

spice moss
#

insulation is the key for it

indigo jetty
#

As the ledInfo is just a const it could be passed in from userland on setup

spice moss
#

does it draw too much power?

#

or is the current for it const as ledinfo is const

#

could be that power is in the treshold when it go on and off

polar wraith
#

@indigo jetty Hey, late to the party here. How about using a JSON formatted file for the config? That way, if you or anyone wants to extend it to be web-controllable it's all ready for the user input....

indigo jetty
#

The config is an array of structs that represents some form of witch craft that @JonXP created

#

That may not be the technical explanation, but it's the best I got ๐Ÿ˜‚

#

The patterns are relatively short functions that use that data to decide what colour they should be

#

Based on said witch craft

#

I will be developing a type of something to fast led converter alright

#

For the Web control

#

Normally I would use json, but it's probably a lot more memory hungry than an array of structs

#

Will have to see though

polar wraith
#

Yeah, it would be. I was just thinking of simplifying the back end-to-web-service interface.

indigo jetty
#

Yeah I think it will need to be sent as json

#

But on a as needs basis

#

So only send an update for changed ones

#

And the uC updates its struct array

#

Not sure though

#

Will have to see how it goes

polar wraith
#

Makes sense. The devil, as they say, though, is in the details....

indigo jetty
#

Yeah, I think it was Mike Tyson that said everyone had a plan till they get punched in the face

#

Will have to see what punches are waiting for me ๐Ÿ˜‚

polar wraith
#

LOL. The Marines say something similar - no plan survives first contact with the enemy.

indigo jetty
#

Awesome looking! Is it diy?

polar wraith
#

I don't think so. If it is, they did a fabulous job. I was looking at the ight sockets....

spice moss
#

well technology can be seen as magic

indigo jetty
#

Here's a note i created for myself

#

Check the date, my project has been a long time coming!

spice moss
#

long time but it's good

viral spruce
#

I think I just found my inspiration for the 2018 BSides Boston badge

lost condor
#

@polar wraith @indigo jetty The array is position information about the LEDs stored in PROGMEM. It includes the cartesian and polar coordinates for each LED in both real and 8-bit scaled space. It's precalculated for speed reasons (inverse tangents aren't super fast on AVR ๐Ÿ˜„).

viral spruce
#

@lost condor good idea storing positions in flash

lost condor
#

@viral spruce It was a necessity ๐Ÿ˜„ 144 * 13 bytes is a lot of RAM.

#

This project has been a fun study in memory management. Like when I found out C++ inheritance wouldn't work for me, since virtual functions add 4 bytes per function per instance

#

I was really surprised about that

#

Though I'm basically violating YAGNI right now. I can get by with five bytes, and the targeted project resolution is too low to make the 8-bit rounding errors apparent.

indigo jetty
#

@lost condor would you have interest in putting the led code into an Arduino library? I wouldn't mind doing/helping with the work around it if you wanted. There isn't much to it

lost condor
#

That would be fun. I'd need to do some work to make it more general purpose.

#

Like have the option for the PositionInfo to not be in PROGMEM

#

And make the code proper C++, not my insane version of it.

indigo jetty
#

Haha

#

If it works it works ๐Ÿ˜‚

#

As the old saying goes, if you aren't at least a little bit embarrassed by what you are releasing you are releasing too late ๐Ÿ˜‹

lost condor
#

Haha

#

Well, honestly, I want a better way to manage the code in palettes.h and patterns.h

#

I'm using typedefs, macros, and static class members when I'd prefer to be using inheritence.

#

However, the memory overhead was surprising and significant doing it the "right" way.

#

This leads me to believe that I'm fundamentally misunderstanding something about the right way to do what I'm doing.

indigo jetty
#

@lost condor just a thought, you could maybe store reference to a function as a pointer for each pattern

#

So rather than it be a class, it could be a struct

#

Don't know if that makes sense

#

Not sure on the impact of memory of doing that

lost condor
#

That's what I did. ๐Ÿ˜„

indigo jetty
#

Are they not each a class?

#

I'm cooking at the moment and just was thinking about it so I didn't even check! ๐Ÿ˜ฑ

#

I thought they were each a class with static methods

runic elbow
#

I hate everything about this situation.

indigo jetty
#

Ide cables, Rocking it old school

runic elbow
#

Yep.

#

I don't understand how this didn't make everyone go insane.

#

I can't figure out how to put th drive in slave mode.

#

All I wanted was an extra drive.

#

Ok, I think I got it.

lost condor
#

@indigo jetty They are each a class for organization reasons, but the array is actually just function pointers to the static methods.

#

There's a macro and typedefs handling all that.

indigo jetty

Wide angle lenses defintely make the job easier

#

My problem is always getting decent sound.

#

I don't want to spring for Adobe Premiere, but I've yet to find anything else that was any good at syncing up off camera sound

polar wraith
#

Yeah, @jaswope, I'm trying to avoid spending a mound of dollars on video equipment and software. I'd rather spend those funds on electronics....

abstract violet
#

@polar wraith cool video! and yes, lenses can cost ... $$$$$

#

@polar wraith I have a Lumix with a Leica 24-70 f2.8 that shoots 4k, that range is good on wide / 75mm for portrait stuff. Have you looked at mirrorless cameras? (Sony etc)

thick ibex
#

Hey guys

#

On a website I am building, I have this element with a specific color
http://rgb.to/rgb/0,255,55

It looked really good, but only when nightshift is turned on to full warmth on the mac. Is there a way I can find this color but with nightshift turned off? Thanks.

abstract violet
#

oh you shoot nikon too @polar wraith ๐Ÿ˜„

polar wraith
#

@abstract violet - not yet (mirrorless cameras) though I'm going to start looking. My entry cost is about 600, apparently, since that's how much the 18mm lens would cost.

abstract violet
#

yeah, my wide angle is 1.3k...

#

for video though, have you not looked at the older non-af lenses?

polar wraith
#

Oh, didn't even think of that. As long as it has the F bayonet I'm good.

abstract violet
#

you'd want it manual anyway and some of the lenses from years past that are made of metal can be had for less than a price of a new ED lens

#

yeah! thats whats cool about nikon vs. canon, is the backlog of lenses you have access to

polar wraith
#

I have a ton of glass (I used to shoot sports professionally). My favorite is the 70-200 AF VR.

abstract violet
#

Sigma's ART series has been getting great bang-for-buck reviews but those arent in wide angle yet...

#

yeah my favourite and also my least favourite to carry is my 70-200 VRII f2.8

#

I had to wear wrist braces to sleep after a day of shooting with it

polar wraith
#

It gets heavy but it's a fabulous lens!

abstract violet

I do portraits, prolly my most flattering portrait lens

I shot the Volvo Ocean Race for Volvo using a 200-400 ED AF VR I got from NPS.

that thing was very over engineered, but it was super impressive

I think it cost that at release, yeah.

indigo jetty

insane

viral spruce

It's been lowered to $400, though.

Harbor Freight is a great weekender warrior tool supplier. Most of their stuff is...adequate. At a reasonable price. I like to say, it's a great place to first buy a tool you're unsure if you'll be using it a lot.

If you wear out a HFT tool, then it's usually worth getting a better model. Otherwise, if you use 2-3 times a year, you saved money instead of buying contractor's grade.

#

Personally, I love yard sales, flea markets, and Craigslist. Usual "buyer beware" applies, but you can find some stellar deals if you're patient and willing to haggle.

Got a 1970s Craftsman table top chop saw with beefy stand for $5. No, that's not a typo. Five smackeroos. Person selling it knew what it was worth, but didn't have the physical strength to lug it around nor the desire to use it anymore.

polar wraith

Nice! I have no place to put a chop saw, but nice!

Neither do I, but Dad does ๐Ÿ˜‰ Made his day, that's for sure. And I always can come home to use it.

But yard sales are great like that....but you can be taken for a ride, paying more than retail for something beat up -- or worse, stolen. Gotta be smart about it.

@polar wraith how are you finding the new multimeter? I'm thinking of getting it maybe

#

There seems to be a version with a thermometer attachment too which looks interesting

polar wraith
#

@indigo jetty I haven't actually fired it up yet. I've been getting ready for my Hack A Thon project.

indigo jetty
#

No problem, when is that starting?

polar wraith
#

This morning. The team is designing an open source radio interferometer (radio telescope)

indigo jetty
#

Exciting!

#

Sounds like a much more exciting day in work than mine

#

At least mind is nearly done

abstract violet
#

@indigo jetty is your new video up?

indigo jetty
#

Nope!

#

Ran out of time!

#

I'll probably try do some tonight but I really doubt I'll get it done either

#

I got the project done (at least a first version) but I haven't started putting the video together at all

abstract violet
#

Oh I thought you had one for Sunday, thought I missed it

indigo jetty
#

I had permission to make one but i didnt get it done in time

#

"permission" isnt quite right

indigo jetty
#

I fixed the AnalogWrite issue I was having with the ESP8266

#

It looks like to use it like a digital pin after you do an analogWrite you first need to analogWrite 0 to it

abstract violet
#

@indigo jetty what were you trying to do?

elfin wave
#

Python and Go have ruined me. I keep forgetting my semicolons in the Arduino ide

viral spruce
#

@elfin wave YES! I've been doing the same

#

although, you can do semicolons in python

hollow oasis
#

O.o you can?

elfin wave
#

Made some good progress on the code I was working on. Taking the streaming radio project from Adabox004 and adding the LCD from 003 to display song info. Except that's actually kinda involved, so it's been baby steps.

#

I'll write something up somewhere once it's done but you have to pass a header saying you want the metadata, parse the header for a value N and then every N bytes read in a metadata string instead of audio data, then start the count over.

lost condor
#

Cool stuff. I started down that path for a javascript thing at one point, but realized after a bit that my source wasn't actually setting the metadata. ๐Ÿ˜„

abstract violet
#

what are you working on @lost condor ?

#

the new name thing confuses me xP

Haha sorry. The new name matches my githubbing (rather than my gaming)

@lost condor haha I like that, "Githubbing"

indigo jetty
#

It's a Web remote for the lights in my Daughters room

#

Dim want working before, if I set analog write the value on the pin wasn't changing when I did a digital write

hollow oasis
#

Oooh!

#

Nice

#

@indigo jetty I wonder if it is possible to set up a server so that a url resolves to the ip address?

indigo jetty
#

There is a couple of different ways you could approach that

#

There is a multicast Dns library (that seems to have originally been written by adapeep Tony D!)

#

But it seems like it requires you to have something installed on your device

#

(bonjour on a Windows machine)

hollow oasis
#

Or connected to a router that you control

#

Like a Raspberry Pi 3

indigo jetty
#

True actually

#

My router is very flexible, I never thought of that

hollow oasis
#

I think there might be DNS settings in the router that you can set

indigo jetty
#

It's not a pi, it's a Mikrotik, but you can set it up to do all sorts of stuff

#

It's not exactly consumer grade

#

Let me check

hollow oasis
#

Seems like setting up a static DNS is a single line!

indigo jetty
#

Yeah!

#

Perfect!

#

Will try that later

hollow oasis
#

Yay!

indigo jetty
#

Thanks for the suggestion @hollow oasis

hollow oasis
#

You are welcome

indigo jetty
#

This was my previous solution ๐Ÿ˜‚

#

I had it sending me a telegram message on start up

hollow oasis
#

Gotta love that Telegram bots

#

*those

indigo jetty
#

It does get the same ip all the time, but i was trying a couple of different devices

hollow oasis
#

Hahaha that's a pretty smart solution actually

indigo jetty
#

Have you used Telegram on the esp8266 much?

hollow oasis
#

O.o you got it on the ESP8266?

indigo jetty
#

Yeah!

hollow oasis
#

I was using it to listen and run on my Raspberry Pi server

#

How?

indigo jetty
#

This is my baby (don't tell my human baby)

#

It's on the library manager too

hollow oasis
#

Ooooh dang!

indigo jetty
#

If you are used to telegram bots its a little slow compared to one running on an actual server

hollow oasis
#

Well that solves the problem of needing an interim server for the bot

indigo jetty
#

But for sending a message on an event or messaging it a command it's really good

hollow oasis
#

Very very nice

indigo jetty
#

Let me know if you have any questions on it

hollow oasis
#

I definitely will

indigo jetty
#

It's pretty easy to set up I hope

#

That's one of my first videos, the pace is a little slow but it gives an overview of the libraries features

hollow oasis
#

You should link it on the github page!

indigo jetty
#

I should

#

I'm making a new one soon

#

And writing it up as a learn guide

#

It was the first thing I tried to do when I got an esp8266

hollow oasis
#

I like you have push notifications. I remember that the python library for telegram broke if you listened for too long > 1h

indigo jetty
#

I've had it running for weeks on a devices without issues, but I'm definitely using too much Arduino strings

#

So it could be made more efficient

#

Yeah for the project in the pictures I'm not even listening for messages, I just send the ip in the setup and that's it

hollow oasis
#

That is really neat though

#

Like usually I have to discover it either on an OLED or through Serial

#

Or peer into my router

indigo jetty
#

Thanks!

hollow oasis
#

I would say that's a use case you can point to ๐Ÿ˜‰

indigo jetty
#

Yeah

#

Do you use Telegram much? Most people don't or haven't even heard of it!

hollow oasis
#

Pretty much. It really depends on where you are.

#

Those of my friends who use it have me as the only contact, since it is the fastest way to reach me

#

:p

indigo jetty
#

Haha

hollow oasis
#

But in other places the use is almost like 50%

indigo jetty
#

I did a bit of work on bots on it using nodejs, I think it's such a powerful interface

#

Some of the things you can do with it are amazing

#

I was backing up a database using a bot for a while

#

I had a cron script that would tar up the dB file and send it to a chat using curl

#

Worked amazing

#

And they are all still there ๐Ÿ˜ฑ

#

If you are into UK soccer I wrote a bot that would take all the goals clips on r/soccer and post them to a channel

#

I hacked it together as my first bot and it's still going strong ๐Ÿ˜‚

hollow oasis
#

Hahaha wow! That's a lot of work

indigo jetty
#

It actually wasn't bad!

hollow oasis
#

I only wrote one bot in python

#

Used it for room voice control.

indigo jetty
hollow oasis
#

But turns out that since the switch is two steps away, I never really used it

indigo jetty
#

Haha

hollow oasis
#

I wonder if one can write a news aggregator bot and feed you news in trickles

indigo jetty
#

I spent a good bit of time making a game for it, that was pretty fun but it was too complicated to play

hollow oasis
#

Oh?

indigo jetty
#

It was basically cards against humanity with gifs

hollow oasis
#

Hahahaaa

indigo jetty
#

I doubt it's still uo

#

Yeah seems to be not running

#

You nearly needed me in the game with you to explain it all ๐Ÿ˜‚

#

I must open source it actually

hollow oasis
#

Sounds pretty complex!

indigo jetty
#

You would add the bot to a group, and then open a chat directly with the bot

#

It would post "my reaction when I get the latest Adabox" or Something

#

And you would message the chat directly a gif

#

And when everyone had submitted it would anonymously post the gifs in the group chat

#

And you would vote for your favourite

#

We even built a site that would display the top used gifs and most recent winning combinations etc

#

It was a real lesson in get some feedback early on before committing

#

3 of us spent the cuts of 2 full time weeks on it

#

And had about 20 users ๐Ÿ˜‚

#

We had done some play testing, but always with one of us

indigo jetty
#

Sigh, I can only imagine the crappy comments someone popular gets

#

It would be OK other than the "..... WHY"

hollow oasis
#

Aw man

#

Hey 20 users still pretty good!

indigo jetty
#

@hollow oasis the static DNS entry works!

#

one problem with it is Chrome doing a google search if it doesnt recognise the URL

#

so it needs to be a valid URL basically to trigger the DNS lookup

elfin wave
#

are you mucking around with hostfiles?

#

(I used to work with the guy who wrote that. Gasmask is a good OS X alternative, and then if you're on linux and need one I can find that too)

indigo jetty
#

A level beyond that I guess, I'm adding a static entry to my devices Dns server (my router) to resolve a specific dns request to an internal ip address

#

That way any device on my network will have that mapping

#

I love the name of that website though!

elfin wave
#

I assume it was a github auto-suggestion

#

but that sounds really cool!

Is adafruit using discord for internal chat as well ? we (as a company) are looking to get off hipchat

#

and while slack is better i'm not married to it...

upper fox

^Agreed

elfin wave
#

and you can't host your own, right? I think that's one of hipchat's pros

this is already leaps ahead of hipchat

A decent working app doesn't seem to be either ๐Ÿ˜‚

#

I am very surprised how feature full it is though

grave crest
#

Well, to be fair, discord works rather well on my android phone and ipad... far better than skype -ever- did

indigo jetty
#

It's not a million miles away from being a slack competitor

upper fox
#

As soon as they figure out how to monetize it within that market

indigo jetty
#

A couple of things, the repeating message bug when in low cell coverage is awful. Losing your input if you rotate your screen is kinda bad

#

Also related to low signal, I'll have a push notification that somebody said something and I'll open the channel and it takes ages to load what that person said!

grave crest
#

Ah i haven't hit any of them, mainly because i never rotate :) nor do i get into low cellular and open discord. But yeah, that could be a huge pain

What IDE for embedded dev do you guys use @night crescent ?

stuck moth

@hollow oasis I use atom for everything. not really an IDE though

#

I prefer separate tools rather than one monolithic one

lost condor
#

I use VisualMicro for Visual Studio. It doesn't actually provide too much help, but it prevents having to wait till compile time to catch simple mistakes.

#

I still use the Arduino IDE for programming though, it seems to produce smaller binaries out of the box, and I don't have any issues writing the program.

#

Not that I'm at adafruit, just thought I'd chime in. ๐Ÿ˜„

indigo jetty
#

I mostly use Arduino ide too, but I really shouldn't

#

I use atom for everything else

#

why is compressing a gif so hard?

indigo jetty
#

(just about)

polar wraith
#

@indigo jetty I started using vi in 1984 when I was helping write the TCP stack for BSD 2.9....

stuck moth
#

its a screencap so it should be super straightforward

polar wraith
#

@stuck moth What's the problem with compressing?

indigo jetty
#

I was minus -3 at that time, not overly concerned about tcp

polar wraith
#

LOL

stuck moth
#

the gif size is either gigantic or has artifacts

polar wraith
#

Ahhh. Perhaps the GIF is already at a high entropy, so "compressing" actually expands the file size

#

(compression algorithms tend to take advantage of entropy "space" in the source file....)

stuck moth
#

its 1.03mb mov file. the gif shouldn't be any larger than it

indigo jetty
#

Gif is a bad format for compression right?

polar wraith
#

Hmmm, not that familiar with the MOV format. I know that compressing a jpg, for example, will make the compressed file larger.

indigo jetty
#

I know very little about it, but if a you had a 10 second video that was all black, the video would realise nothing had changed and it would be tiny

#

Gif is just a collection of images

stuck moth
#

yeah, thats kinda what I expect here. most of the image is identical in all of the frames

indigo jetty
#

They don't know about each other, so each frame needs all the story

polar wraith
#

Interesting. It should be compressible, then.

stuck moth
#

gif can do diffs across frames

indigo jetty
#

Unless I'm mistaken

#

Oh ok

stuck moth
indigo jetty
#

I thought that was the advantage of the newer html5y formats

Oh well, next one!

@indigo jetty , good video.

#

Thank you @hyp3rMC

stuck moth
#

@abstract violet I think you are thinking of @dry sphinx mouth joystick

abstract violet
#

@stuck moth ah thanks! yes! One of the things I appreciate about getting into electronics is a new perspective on technology in regards to hardware. The face of an ultrasonic sensor is a familiar one (wouldn't have recognized it a few months ago...) so its funny to see on a commercial product and go, "hey that's something anybody could make for less!" --

stuck moth
#

@abstract violet totally! I find I am more willing to fix things too

#

I actually resoldered the usb connector in my kindle ๐Ÿ˜ƒ

#

fixed the charging issues I was having

abstract violet
#

@stuck moth Yeah, I feel more confident about fixing my own devices too! Even those with literally zero documentation/support/replacement parts glares at my pebble watch

stuck moth
#

yeah... I bailed to apple watch but am still hoping fitbit gets its act together

abstract violet
#

@stuck moth yeah I love the apple watch, esp the bluefruit app -- i may have used that as a reason to get one XD

stuck moth
#

๐Ÿ˜ƒ collin woul dbe happy to hear that

#

Hello people. I was up till 1am with Adam and his Scanning Electron Miroscope. That thing is amazing. I highly recommend checking out his pics and gifs he posted.

abstract violet
#

@stuck moth pebble released an update so you can run it without their services, but it was cool that they even had a web-api to create watch apps using javascript i think.. wonder if fitbit will have this sort of functionality in their future line

#

@pallid pivot g'morning!

pallid pivot
#

@abstract violet And a top of the morning to you too.

stuck moth
#

@abstract violet I wish they'd make something cheaper and not do apps. I want a watch with notifications for cheap

pallid pivot
#

@stuck moth I have a "Notifier" that never fails. Her name is Ann. ๐Ÿ˜ƒ

abstract violet
#

@stuck moth have you seen the screens on pebble devices? are they available for consumer purchase -- I think it'd be a great Gemma M0 project.. seems like a good size.

polar wraith
#

@pallid pivot totally agree. The SEM was just amazing.

pallid pivot
#

@polar wraith Wasn't that the coolest thing you ever saw. And to think he's doing it in his garage. Ya gotta love it...

stuck moth
#

@abstract violet I've never seen them separately. it would be super cool

polar wraith
#

@pallid pivot and the Z Machine was pretty cool, too. But yeah, Scanning Electron Microscope ... in the garage.

pallid pivot
#

@polar wraith Oh yeah, The Z maxhine, I allmost forgot about it. Got google that for my SHBB, (Steamy Hot Bubble Bath), they're very thareputic.

#

@stuck moth would be cool if adafruit stocked these displays โ˜บ๏ธ the watch thickness is like 7.5mm, the display-- even thinner

#

30mAh battery lasts 2-3 days without charging..

stuck moth
#

know where to get them?

indigo jetty
#

@stuck moth check out the xaomi smart band, it supports basic notifications (not reading them) and it's only $20-25

abstract violet
#

@stuck moth its a sharp display! apparently available on mousser

indigo jetty
#

Smart band 2 sorry

stuck moth
#

@indigo jetty that sounds like what I'm thinking

#

@abstract violet why not just buy it from mouser then?

indigo jetty
#

Iirc The notifications require an app called my bands tools

abstract violet
#

would take a lot more resources and time out of me to create the ribbon connectors/pcb etc.. and write the drivers etc...

indigo jetty
#

But it's a really nice device for the price

stuck moth
#

ah, so we'd need a driver fo rit

@stuck moth ever had a fuelband?

#

Say, has anyone done a comparison of Ultimate GPS vs. the other popular ones like UBlox? I didn't find anything in blogs or the learn system, but I figure I should ask....

abstract violet
#

@polar wraith ublocks which version? IIRC, ublox neo6 has 6 North American Sattelites, neo7 has access to both north american + russian sats.. and the ultimate gps has access to 22...

polar wraith
#

@abstract violet I have (naturally) a number of Ultimate GPS boards, but I also have the UBlox 6N, 7-something, and now an 8 something, so I was going to compare them all.

abstract violet
#

@polar wraith I think all of them are within 10 meter accuracy, with the ultimate being more accurate..

polar wraith
#

Yeah, it's the accuracy I want to write about.

abstract violet
#

@polar wraith could you use wifi to help with accuracy in combination with the ultimate gps?

polar wraith
#

I don't know. I was actually just thinking of doing differential GPS in software with them....

abstract violet
#

@polar wraith may not work if your application is in the waters away from wifi too xD

polar wraith
#

Well, true, but I was going to test on land. ๐Ÿ˜ƒ

stuck moth
#

the newest ublox stuff uses a fourth local distance measurement to get really good accuracy I think

polar wraith
#

Oh, that'll be interesting. My UBlox8 is literally sitting in ESD packaging on my bench, so I just got it. It will be interesting to see what kind of non-GPS satellite coverage I can get.

stuck moth
#

it requires a separate base station though

polar wraith
#

Thanks, @stuck moth. I'll check into it. Don't be surprised if I show up at lunch with a bag full of GPS devices collecting data. ๐Ÿ˜ƒ

stuck moth
#

๐Ÿ˜ƒ I won't be

pallid pivot
#

@stuck moth Howdy, quick question for ya. You know the Circuit Playground right? If you place it on its edge and roll it across the table and knowing its circumference, can I use the data from the Accel to figure out how far it rolled???

stuck moth
#

@pallid pivot probably. seems like a sound idea

pallid pivot
#

Tapeless Measure 3 going on the Drawing Board. Thanks Scott.

stuck moth
#

๐Ÿ˜ƒ awesome. np

#

Question for the floor: if someone were trying to get a battery for an ANCIENT MacBook, does anyone have recommendations for names which to look for / avoid like the plague?

indigo jetty
#

I think most of them at this stage are going to be sourced from China if you can get them at all

indigo jetty
#

@pallid pivot you would have to try ensure no slippage, a bare PCB board would be kind of slippy

#

Maybe a rubber band or something?

#

What would you rotate it around?

pallid pivot
#

@indigo jetty Oh, I know, your right, my idea is to 3D print a wheel big enough to hold the CPExpress, battery, Emic2, and small speaker and then put a rubber tire onto that wheel. It would probably be at least 3 inches in diameter.

indigo jetty
#

Yeah cool

#

Sounds interesting!

#

It's a good idea using the accelerometer

#

There was a tv show from the UK and Ireland where there was a joke product of sellotape (sticky tape?) dispenser that called out how much you used, I've been meaning to make it, sounds like you are almost designing it for me ๐Ÿ˜‚

pallid pivot
#

@indigo jetty I just needed a project for the CP Express I received compliments of Adafruit. My Tapeless Measure now has the Show and Tell sticker on it. My Tapeless Measure 2 is off the drawing board and onto the breadboard at about 20% complete. So this would be Tapeless Measure 3. Simply roll it over a surface and it will speak its distance traveled while traveling. I know, I have big grandiose ideas, but hey, why not?

polar wraith
#

@pallid pivot most rovers use a camera that physically looks at the wheels turning in order to do that. I wonder why not use your method, or rotary encoders....

#

I like your solution better, provided sufficient update rate.

pallid pivot
#

@polar wraith Yeah, it sounds doable, but is the Accel acuracy enough. Lots of question to investigate, but that's half the fun.

polar wraith
#

You should have a consistent acceleration of -9.8m/s^2 "down", so you can track that acceleration as it moves "around" the sensor.... It should work as long as the wheel isn't turning faster than the device update rate.

pallid pivot
#

@polar wraith Yup, nice work man, thinking like a true technologist. Thanks for the info.

polar wraith
#

LOL. No worries.

dusty citrus
#

Wild guesses (only):

Kepler noted that the planets in their orbits sweep out equal areas in equal times.

The CPX won't be mounted exactly centred on another wheel -- the axle goes there (if there is one).

A highly eccentric curve described by the centre of the location of the sensor on the board might give a much higher resolution of the displacement distance between the sensor and the tabletop -- caused by mounting it way off centre.

#

I'm thinking an array of sensors spread near the perimeter of the contact wheel.

#

Each one probably loses accuracy/resolution during some part of its journey about the centre of rotation of the pilot wheel.

#

So, like a motor's armature, each one is on-duty for high accuracy, part time. This also gives more time for computation during a single rotation of the pilot.

#

The CPX zeroes out the z-axis sensor when it is rolled on edge as described.

#

When you get such a null on the Z, that leaves X and Y to report differences.

#

I'm guessing they report orientation, not displacement from any surface. how could they. really.

#

So range information (to the tabletop) would be computed values from physical constants (primarily: dimensions of the wheel and distance to the edge of the wheel of the sensor, which would be taken as a fixed value (constant).

#

the value of g does not range much in the distances involved.

#

And I'm back quiet.

Way off topic, but ... Soyuz MS-05 has docked with the ISS and they're about to open the hatch. You can watch on nasa.gov and follow the links to NASA TV.

Neither have I been to a launch. Pretty exciting stuff!

dusty citrus
#

SpaceX is particularly interesting.

polar wraith
#

Yes, I'm a big Elon/SpaceX fan...

pallid pivot
#

Rockets? Did someone say Rockets???

polar wraith
#

Indeed, @pallid pivot ! We did bring up rockets.

pallid pivot
#

@polar wraith I see, ummmm, I'm sort of addicted to rockets so when I see or hear anything about them, well, I sort of got to know what's going with them. It's a life long passion since watching Neil and the guys go to the moon when I was a young kid. My "Dark Blue Yonder" flew to over 10,000 feet more than once and broke the sound barrier twice. I was maybe 6 months away from Level 3 Certification (M, N, O motors) when 9/11 happened. Consequently, this resulted in the end of my High Power Rocketry days.

pallid pivot
#

She's a small rocket but was quite a "Hotrod" in her day...

polar wraith
#

@pallid pivot Why did 9/11 put an end to your high powered rocketry? Tripoli is still around, isn't it?

#

(and I started thinking about sticking my toes back in it. Was looking at some E and F series engines and rockets today.)

pallid pivot
#

@polar wraith Oh yes, Tripoli is doing just fine. But when they allowed us to launch again after about a year they added a bunch of rules and regulations and fee's and and required a Warrentless search and it just got to much to deal with and besides, at that level, it's very expensive. So, I just never got back into it. And, I had pranged my booster that I built for Blue on that final August launch. Blue staged and flew great, but the boosters altimeter didn't breath and it came down fast and hard. That was a $500+ loss which needed to be rebuilt anyways so I focused my interests elswhere.

polar wraith
#

Ugh. What a pain. I'm sorry to hear that. Particularly the "warrantless search" part.

pallid pivot
#

Well, they just want to make sure the magazine used to store the APCP fuel is up to standards. But still, your right, I didn't like that.

polar wraith
#

I mean, I'm pretty sure FFLs have to deal with the same thing with the ATF....

#

Nonetheless....

#

I'm just sensitive about surveillance states for ... reasons.

pallid pivot
#

Yes, however, there is more to the story. You see, they new the hobby was growing and that more of us would want to store our own propellent and they were right. So they said they would make it ewasier to get the peopellent but we want to make sure it is stored properly. Sort of a give and take.

polar wraith
#

Hmmm. Would be fun to make a liquid fueled engine. I wonder if that's even legal....

@pallid pivot you should upload it to YouTube. I'll take a look it when I'm not on my phone, looking forward to seeing it!

#

Very nice @pallid pivot... these days, add a neural net and she can figure out what to pick up and everything...

#

I'm amazed at the tensorflow recognition stuff getting squeezed down into mobile sizes.

pallid pivot
#

@dusty citrus Ya know, I've spent a lot of time studying ANN's and tried a few in C++. But I found a book that decribes a thing called "Reflex Arc's" and using that along with "Natural Language Analysis" for spoken sentence understanding in order to have ROSIE respond in an expected manner may work out rather nicely.

#

Right now, my main concern is the interconnection between the various processors used to contruct ROSIE. Consider this, a Mega 2560 in the arm, a pyBoard brain, an UNO w/MOVI for voice in/out, another pyboard on the OpenMV camera for sight. How do I have all these guys talk to each other?

@hollow oasis Since I only memorize it for the current year (Tuesday in 2017) it's little work for me to use it. Instead of finding a calendar and consulting it, when someone mentions a date (but not a day of the 7-day week) I pretty much instantly know the answer to the question: What day does that fall on.. Thursday? Friday?

I always know.
