I found some cheap clear 1" heat shrink on ebay. Interestingly even though my cicuit board is 1" square, it fits in 1" wide heat shrink. Trying to allow the battery to still be changed, after being encased in heat shrink, i found a cr2032 holder...
This has been an ongoing project for over a year before being added here, so in addition to the overall design here, I will merge everything done so far into a the first log rather than trying to separate everything as it happened. Several years ago,...
I've created a fairly detailed bill of materials that details everything you'll need. You'll also need to solder some unique USB cables together. See the pictures.The power supply board turns on when the power button is pressed, and stays on for a bout...
Keyboard with color keys.... consists of two 74hc595 and one atmega8. Firmware does keyboard scan and acts as an SPI slave to the Raspberry Pi. Commands are 1 byte long are used to report state of the keyboard, four keys per time.Userspace keyboard driver...
Current Features: Record's videoCan stream video to outside source like TwitchCan switch between being a WIFI client device and acting as a AP Host to connect to the pi directlyPI can server a web UI to interact with the device and edit various settingsRealtime...
We were not sure if there was going to be an In-Person version of DEFCON this year so we had nothing prepared. This badge was literally started in early June! Talk about rushing things.This time the badge is simpler, with no sound, no RGB LEDs (just...
Putting things together was straight forward. I took the code from Adafruit: Multi-tasking the arduino part 2 which I modified for 1 servo and 1 LED only. Moreover, since I use an ATtiny85, I had to call the SoftServo library instead of the normal servo...
The size of the board is the standard size business card 8.9 x 5.1 cm. On it there is 2.7" GDEW027W3 e-paper display from Good Display (2 or 3 colors both work just fine). One thing that is very important to me is that the device is very slim. This is...
Board Specifications This Panel meter uses the SSD1306 OLED display and INA226 power monitor IC. The INA226 can measure voltages up to 36v and currents up to 5A with the 5mΩ high-side current sense resistor. The INA226 has an offset voltage max...
The Flea-Scope User's Guide (including some "how it works" internals and full specifications) is here: https://rtestardi.github.io/usbte/flea-scope.pdf A preliminary video introduction is here. BTW, I just got assembled boards back from pcbway.com...
So, we're going to need to do some CAD, therefore we'll need some CAD software. There are some nice free-to-use choices out there: tinkercad.com, easily accessible on the web and runs in your browserMicrosoft's 3D Builder, built into Windows...
Project goals:* make a keyboard which is sufficiently thin to fit inside steamdeck official case* experiment with making flex PCBs using copper tape and a vinyl cutter (both as cheap flex PCBs and rapid PCB prototyping in general) Keyboard stackup:*...
The DevTerm keeps popping up at my feet at regular intervals. It's beautiful but it comes at a price - $339 is a bit much for a toy and not in the budget here. If you don't have the budget, you'll probably have to build it yourself. Devterm didn't invent...
There it is - we are live on Kickstarterexactly as planned the campaign launched a few minutes ago. Make sure to grab your board as long as the early birds are available.https://www.kickstarter.com/projects/pascalwistinghausen/sigmoid-s7p-closing-the-gap-in-3d-printer-controlIt´s...
This began as a hackathon entry but is evolving into something more mature. I have selected components for prototyping but will eventually need someone with hardware expertise to help with preparation for mass production. The MCU used has way too many...
