Screen shifting
Log from HACKtablet: Crestron TSS-752 Teardown + Rebuild
I manually merged in some of the recent updates to the ESP-IDF for the ESP32-S3 LCD peripheral by @suda-morris and that seems to have banished the screen offsets. Here is a link to the issue requesting a back port of these fixes to ESP-IDF version...

GamePad module and Trinket M0 Haxpress
Log from PewPew FeatherWing
My pull requests just got merged into CircuitPython. One is the for the Trinket M0 with a hacked on flash chip — it's now called Trinket M0 Haxpress, and the other one is adding a gamepad module with functions for scanning and de-bouncing button presses.I'm...

The Look-up Table Holds the Secret
Log from CircuitPython Badge
I spent half of the last night poring over the datasheets and wading through horrible C code examples, but finally I managed to find the code that was used to make this example:Inside I found a lot of scrambled code, unused files, copy-pasted fragments,...

Example of Project

Badges in Vegas, Challenge on boards
Log from A DC27 CircuitPython Shitty Add-On V1.69BIS Totem
DefCon is here! And so are most of the badges. Nothing like a little last minute hotel room soldering sessions to help justify the TS80 purchase and finish off some of the boards that didn't survive the journey. We're starting to hand these out at the...

NKRO and BOOT
Log from Kleks Keyboard
I took the opportunity with this new keyboard and worked a bit on my uKeeb CircuitPython library. With the custom HID descriptors we can have an NKRO keyboard, but there is a small problem: the bitmap device that this uses won't work in BIOS or with...

Published
Log from PewPew LCD
With the second version being pretty much where I wanted it, I decided to go ahead, publish all the designs and code, and once I had done that, apply for the open source hardware certification. The PewPew LCD is now officially certified open source hardware,...

The Stage Library
Log from µGame
The hardware is just a very small part of a project like this one. Of course in the game console the most important part are the games that you can play on it. And the most important part for the games is the development environment and libraries available...

As seen in show and tell
Log from Braille Featherwing
Back in October, I was in Adafruit's Show and Tell, to demonstrate the pre-featherwing version.As you can see in the video, the pre-featherwing has a lot of cables running around, so this was only valid for a prototype useful to develop the HID-Braille...

Important Links
Log from Bats 'n Gons
Soundboard in 10 minutesBOM Github How to build Circuit Python. Hint: look at Trinket config file to configure external flash.

Third Live Stream!
Log from Serpano
The solder party is not stopping until the board is working! Make sure to join Part 3 of the Serpano solder saga as we solder and bring-up the MCU and hopefully get UF2 and CircuitPython working.The stream starts on July 21st at 8PM CEST (~22h from...

first commit
Log from Raspi-Grow
I hooked up the raspberry pi to a monitor mouse + keyboard for first time setup. I followed the steps on the adafruit setup guide for circuit playground and it set up a lot of what I needed it to.

Fluff M0 Micro
Log from Chocolad Keyboard Hacking
Since I wanted to program this keyboard in CircuitPython, I needed a development board that would be compatible pin-wise with the Pro Micro, but use a bit more powerful microcontroller. So I designed this version of #Fluff M0:

Dynamic USB Descriptors
Log from Chocolad Keyboard Hacking
A new feature landed in CircuitPython recently, that allows us to do a neat little trick: we can show the CIRCUITPY disk and Python REPL console, or not, depending on whether a certain key is pressed when the keyboard is powered up or reset.Why is this...

Great Success
Log from PewPew OLED
Version two has the battery holder tabs longer, and they work just right without breaking!I also left out one of the capacitors — I guess the displays works without filtering its power.The latest CircuitPython flashed, now time to write some sprite libraries....
