I banged my head against the wall for about an hour until I was able to get the desired output of my nerf scope killcam function. I have tested the function before with video files, this was the first successful test with the camera. It trims the video down to 10 seconds and slows it down to half speed and applies a cv2.HOGDescriptor()

Doesn't matter as much at nerf ranges as much as longer range situations

Yeah but what if someone use someone else body as cover and you have to apply more force to reach them or switch to and penetrate the body with AP nerf ammo ?
lucid bloom
Usually when I use my old one it's all vs me cuz I'm basically cheating. I have my single shot pistol and I can take on a much larger force with better arms.
The opposition strategy is to bumrush me

Also noticed you don't have thermal / flir so how do you know a target has been destroyed without the body heat? (I assume this is for some kind of automatic track and engage turret?)

My home made "weather indicator" iot device. Based on api calls to openweather, it indicates current temperature and wind speeds on the bottom row, max heat index and wind speeds on the left, and chances for rain on the right for the next 4 hours. RGB values are customized for how I perceive heat and cold. It's based on the ESP32-S2 QT Py running circuit python, and the 3d printed case from them that I've mod'd in tinkercad to snap together the acrylic cover and LED strip holder. It was fun working on an interface that didn't use word or numbers to convey information.

I designed an octopus that makes use of: a distance sensor, 2 LED rings, a QTPY RP2040, and a 1w speaker. I saw mark's insect bot last week on show and tell, and realized I may have been inspired by his use of a distance sensor for eyes. I printed the base in TPU with channels in the legs to insert some brass wire. So the legs are posable. A simpleio.tone uses the distance sensor for note pitch and duration, except for the “close up” sounds where I'm mixing 2 sine waves. https://youtu.be/3FeENYyghFc

Oh boy, finally figured out a solution to what I need. This is an RP2040 running CircuitPython using I2C to read output from an RP2040 running C/C++ which is importing Arduino's Wire.h library using pico-arduino-compat. This is a first step of many after so many hours of troubleshooting, all because I require usage of an Airlift ESP32, TinyUSB host mode, and stubbornly not buying the Arduino RP2040 Connect after it came back in stock 2 days into the project.

I made a Sonos Port alternative out of just a Raspberry Pi Zero W and a USB ADC/DAC. It can stream an audio input from a turntable, cassette deck, etc. to a Sonos system.

That'd depend on the details of the design. Often it's more complicated to coordinate and make efficient use of multiple chips versus just upgrading to a single more powerful processor.

??? isn't the black thing pro photography lenses ?
Nah, just a C-mount lens from Arducam that I got on Amazon for about $65. It's not a very good lens - massive distortion - but most C mount lenses are built for use on CCTV cameras where it'd be fine.
https://www.amazon.com/gp/product/B088GQHVY3
Either way its fun to play with! tbh though the lenses on Adafruit are a lot easier to work with and are a lot smaller. In retrospect I should've just stuck with this one. 🙂
Nice thing about the HQ cam is that it works with all kinds of lenses and adapters, although the small sensor size means it'll "crop in" on a just about any sensor not built for C-mount or small sensors (like 1/2.4" or 1/3")
I have a bunch of Nikon pro lenses for instance that "work" on the HQ cam with a simple mechanical adapter and some shims, like these from Fotodiox: https://fotodioxpro.com/collections/lens-mount-adapters/camera-mount_c-mount

I did the math a bit ago (Since I'm building a camera based on the HQ camera). The Pi HQ camera has a "crop factor" of something around 5.5
whole brook
Arducam is one of the few companies marketing a wide range of C/CS-mount lenses, which is nice. Mostly they're just rebadging stuff from dozens of manufacturers of inexpensive CCTV gear, which is cheaper to get direct on Aliexpress/Alibaba if you're into that kind of thing. Either way, Arducam's product listing offers a nice overview of what's available out there.

Looks like a (nice) CCTV lens to me.
...although I do have a couple of "X-to-Y" adapters which work well for adapting old photo lenses to C or CS mounts. Now that the majority of cameras are auto-everything, you can find some really nice old glass for peanuts. I've picked up old Nikon zooms that I drooled over as a kid, for less than $10, and they work great when coupled with modern electronic imaging elements.

Yeah, tons of options for C/CS-mount, plenty out there with IR capability too I think.
One thing about working with the HQ cam that I noticed though is that lens focal distance is a bit weird, depending on the lens/adapter, so its always good to have a set of shims of various lengths (2mm/2mm/4mm/5mm/etc) ready to go.

The back focus adjustment helps with this. I'm going a bit further (Since I'm designing around an M42 mount) and the original mount won't be there, but I fully expect to have to shim some things.

What often stop me for a camera project unless it's one with long-exposure or under things I can't see because of where my eyes is - is often that it is expensive to see what my eyes can already see

I don't know about the mounting etc, I'm Canadian, so I can use a scope without a firearm I guess 😄
Never seen a mounting from a scope in person obviously except at a canadian army stand when they show their gear
but they didn't detach the scopes, so no idea how they mount and if civilian even have the same mounting
lusty siren
Well, you'd want to put a camera where your eye goes, and eyes notably don't have screw mounts.
solar yew
why? Like a scope show the view from a couple of inches under it ?
I always thought that with a scope you have to adjust the height in your head or something
since it's mounted a few inches above the barrel

it's always a good feeling when people like and use something that I made to be helpful. I live in a touristy area and the bridge traffic is the literal tourist trap which is why I made this. I used to go over the bridges and back every weekend for quite a few years to visit my grandmother so I made something to help myself avoid the traffic. It's like the weather radar apps but for bridge traffic, it really helps being able to see the last hour of traffic to determine if I should stay or if I should go, my original version was not shareable so I made one that is. I use some R code to capture google maps images with the traffic layer, then I use ffmpeg every 5 minutes to redo the gif. I had more than 1000 users over memorial day weekend.

So, I dont have many flashy photos for this but I completed something that Ive always wanted to do: A Buck Converter based Lithium battery charger! I failed once before at this years ago, when I did a first rev of a buck smps that used a synchronous fet. It just never worked correctly. I shelved it until I started up a few months ago and made a boost SMPS based on a few app notes. Then from there, it was easy since I got that running :). This is part of a larger project. Lithium battery SMPS's are a tad expensive, and micro controllers are cheaper. The best thing is, I can also use this for LiFePO4 batteries as well!

Feather M4 nrf52840 Sense with 3.5” TFT featherwing and 3x 18650 battery. Just tested it for battery longevity, made it about 30 hours before cutting off . Values only update every 60 seconds.
Might be able to squeeze out a little more battery by removing the background image and updating labels every 5 minutes?
I’ve recently learned if I add an airlift featherwing this is basically a PyPortal. The bluefruit sense has a few more onboard sensors which can easily be added to a PyPortal with STEMMA connectors. The 3.5” TFT featherwing and bluefruit sense board continue to be out of stock while there are plenty of PyPortals.
If you want to make something like this just go with a PyPortal. The PyPortal costs much less because it’s all in one board vs multiple parts used in my project and the specs of the parts are practically identical.
PyPortal is in the $50 range while my project cost over $100 to make. The choice is simple right now, you get a much better value with a PyPortal out of the box. However, the major benefit of using modular components is you can upgrade in the future to more powerful feather boards.

Had to have surgery on my right arm recently. Its my mousing arm and computing has been hard while I have a splint and sling (only a few more weeks!). Over the weekend I added a trackball to the right side of my trackpad to make only using my left hand easier. I also added macros for mouse related things (clicking, shift-click, copy/paste, scrolling). Holding down the trackball mouse button brings up a menu that lets you lock the press until you click again to make dragging easier.
I'm working on adding t9 support to it. Had a few failed attempts due to memory constraints but found this great project by Guy Dupont that puts the data structure on disk: https://t9-library-generator.uk.r.appspot.com/ He has a full implementation that already works on rp2040 pads but I need to refactor it to work as a mode with my existing code and UI/UX.

nice job. I have one of the 4x4 trellis to play with but since we were going for BIG custom keyboard for the art install the arcade buttons work. Really like the i2c board for this - greatly simplifies soldering/wiring. I have other project where I hacked neopixels inside the buttons.

I've been writing an OpenSCAD module that will construct a enclosure based on a list of specs. You specify the size of the box, how the top and bottom connect, and the location and type of any addons or cutouts. It takes that, creates a model, then lays it out for printing. This one's a custom case designed to hold a set of earphones and a USB dongle. The contours in the bottom of the case are created by taking an SVG image and extruding it upward from the bottom.
Right now, I'm seeing if I can used the same module to generate, say, a custom Raspberry Pi case.

I'm going to try to implement a forecast similar to the hourly overview but goes much farther into the future

What are the nodes going to be used for? Looks like remote LED stick display with 4 key input?
gusty shard
I'm building a multi-processing system. This is just to figure out the inter-processor protocols, based roughly on token ring networking.
The TFT panels track individual frames as they move through the system. The LED stick shows which nodes are in the cache. Each node has a three byte MAC address, so I use that to set the color on the LED. The bottom two track the last node heard and the current receive status.
My next task is to distribute code to each node over the UART link, so I don't have to switch to each node to update the software.

Spent a long time trying out different ways to make masks for my macropad keys... 2 sided laser printing won but i think 3d printing would have worked better if I had resin. Its in T9 mode but it fast switches between that and mouse mode and can still use regular macros via the knob.

This just made sense to make this morning... sending in my JLC order as soon as they fix their website. Guess I'll design a couple extra boards real quick in the mean time.
And a Universal Stemma Adapter board, just solder the jumpers you need in the 4x4 jumper grid. Little bigger than I wanted, and routing was a pain, but I'm going to enjoy using these.

Probably my final iteration of my weather station (code wise)
Four frames in a carousel, which can be switched by touching the yellow wires below (using the touch hardware of the ESP32) which could be hooked up to something metal to act as buttons (I think these are cooler then tactile buttons 🙂)
Unfortunately, I was unable to get the resistive touchscreen to work while also using WiFi (I didn't have enough analog pins)
First frame: Weather today plus 4 days into the future
Second frame: Hourly forecast, 11 hours into the future
Third frame: Daily forecast, 7 days into the future
Fourth frame: Miscellaneous stuff like sunrise/sunset, moon phase, etc. Plus system stats for me to monitor

You know those plastic LED candles online that come with the plastic remote? Well I've had some on my back porch for years and the internals rusted out. So I got a Gemma M0 in today and went looking for a basic 2-pin candle flicker example and came up empty. Jon Park has an example that uses an RGB led which I don't have and Becky Stern has a hair bow example that uses a special flickering LED which I also don't have. So I created an example with a plain old single color LED using random() functions and no external libraries. I think something this basic should be included in a learn guide somewhere.... if one exists I didn't find it. The Gemma and an 18650 battery pack with an on/off switch will get stuffed into the bottom of the candle.

This is the Peaucellier–Lipkin linkage. It moves the end effector in a mechanically perfect straight line perpendicular to the support arm. You can attach a servo horn to the shorter dark grey arm. Great for moving things in straight lines.

Started playing around with printing keycaps in translucent black filament. I want to do my own design so I can control the thickness and make the light go where I want it but they look pretty cool. I'm going to make some masks that let me paint them to reveal glyphs when the LEDs are on.

My friend Markus had grand idea for a party here on Maui last weekend. We built a large rear projection 'TV' with a big remote control that switched different video clips. The remote was a Midi keypad built using 30mm Arcade buttons, a raspberry Pi Pico and 5 Adafruit LED Arcade Button 1x4 - STEMMA QT I2C Breakout boards.

I understand on a better level how capacitors work now! One LED is attached to 5V through a button and ground through a 2kohm resistor. The other LED is attached to an RC circuit with another button. That makes it get dimmer over time unlike the other one that turns off as soon as the button is released. Also on a scale of 1 to serotonin, how clicky are my buttons!

This is a project I have been growing for 3 years or so. We call it the piSwitch. The Christmas tree has 20 different 100 led strings. This has a web server gui.

That looks mildly terrifying, like a portable electric chair. I think it's the vertical ac switches in a box that does it.

I wrote up my explorations of the Adafruit Neotrellis 4x4 keypad with neopixels over on Hackaday.io https://hackaday.io/project/186327-neotrellis-explorations The basic examples in the adafruit_neotrellis library dont go very far. An incompatibility between the seesaw.neopixel and adafruit_neopixel precluded the use of the rather nice adafruit_led_animation library. @solar wadi made a fix to the seesaw library and now its NeoPixel derives from the PixelBuf class, same as regular NeoPixel and DotStar. Using his branch, I was able to get things working. Then I modularized the code a bit, and added MIDI NoteOn NoteOff sending. See the project logs for those enhancements.
mild blade
I wrote up my explorations of the Adafruit Neotrellis 4x4 keypad with neopixels ...
there are still some questions about how well the seesaw.Neopixel branch will work across multiple neotrellis boards (like the 8x8 keypad kit). I have a 2nd 4x4 kit with acrylic, pad, etc. I might put an i2c extension on them so one Feather M4 Express could access both neotrellis. Or now that it works as a midi device, I might leave it for a while and work some other projects.

8-bit parallel ST7789 240x320 LCD paired with a RP2040 MCU
time to parallel "everything" 🙂
exotic sierra
Does it run faster on the 8-bit bus than SPI?
exotic sierra
I thought about using the 8 bit bus but I wasn’t 100% sure if it made a difference in terms of speed.
How did you wire it up?
ruby ledge
DMA hardware driving it. Adafruit PyPortal has the same capability
This is a Pimoroni product - premade that way
exotic sierra
Ah
ruby ledge
They only have a MicroPython lib to talk to the display, so I wrote a native code one. Actually added support for that combo to my bb_spi_lcd library
exotic sierra
I’m making a watch with a small 1.3” st7789 display so the 8 bit bus seems like it would be a cool way to make it faster
ruby ledge
definitely - if you have the spare IO
exotic sierra
I’ve got plenty of IO on my RP2040
ruby ledge
240x240 can be driven pretty fast with SPI, but more speed = less time waiting for the data to transmit
exotic sierra
ruby ledge
max possible framerate for full screen 240x240 w/40Mhz SPI = 43fps
parallel bus running at 20Mhz = 4x faster
Does your board turn off the enable on the LDO to save power during sleep?
because the RP2040 sleep current is a bit high for battery powered devices
exotic sierra
No, but I’ve considered it
ruby ledge
The Pimoroni RP2040 boards use the user buttons to toggle a bit which turns on the power supply
exotic sierra
I added a load switch for the display to turn off power to it when not in use
ruby ledge
ST7789 doesn't draw much while asleep
UnexpectedMaker (Seon) usually has 2 LDOs on his boards to allow selective shutdown of devices
exotic sierra
I’m just basically doing everything to disable power draw like pwm’ing the back light, disabling the power ti the TFT, etc..
ruby ledge
that's a good start. The RP2040 draws a bit over 1mA when in deep sleep. It's a shame because it could be great for low power/low cost projects.
exotic sierra
Currently the design is a 2 layer board with only the FPC connector in the back
ruby ledge
it's a nice looking board
exotic sierra
I could make a separate LDO for the RTC to keep it alive. It uses 350uA during time keeping operations
ruby ledge
that sounds like a lot
exotic sierra
Then disable the LDO for the RP2040
ruby ledge
which RTC?
ruby ledge
is that easier to get than the ones from Maxim?
ruby ledge
I've only played with the DS3231 and PFC8563
exotic sierra
It’s weird to work with. I’ve been trying to get it to send back seconds accurately but it jumps around a lot
ruby ledge
another option for just seconds is a 32768hz crystal

It has one integrated and delivers a clock output
I’m counting roughly 28900 clock edges for a second. I haven’t quite figured out the frequency compensation yet
