I turned down two sponsorship opportunities for the podcasts last month and now qualify for ads from my podcast host. I’m not going to enable them, but I’d love it if you supported the show: www.thebootloader.net/support/

Looking for a fun time in LA tomorrow? Come to the 12th Annual Bob Baker Day all day carnival! Cirque School LA will be there with our outdoor aerial rig performing at 11AM, 12PM, 1:30PM and 2:30PM, I'll be doing my aerial straps act along with other variegated shenanigans. bobbakerday.com

Incredible that this is all running on RP2350, amazing work!

New episodes of The CircuitPython Show and The Bootloader are out! Both shows feature The Bootloader's CircuitPython Day 2026 live stream from the Adafruit YouTube channel. @todbot.com and I share some of our favorite CircuitPython things from the last year. www.thebootloader.net/episodes/202...

can I run Pico-8 on an ESP-32 Pico being emulated on a Raspberry Pi Pico?

I was discussing my love of Toyo steel boxes with @brentrubell.bsky.social I like collecting parts for my current project in them for moving between my studio and workshop.

I was just chatting with @johnpark.bsky.social yesterday about making a modern take of the Model 100, maybe using one of those weird narrow 1280x400 LCDs

this is super helpful, check it out of you need a pin name reference for any CircuitPython board!

Here's a demo of the Attachécade I designed to repurpose a portable phonograph case. @adafruit Learn Guide coming soon.

Coming Monday on a new episode: @todbot.com returns and shares how to build CircuitPython firmware using GitHub Actions and his latest synth board:

It's official: @todbot.com and I will be hosting a LIVE edition of The Bootloader for #CircuitPythonDay2026! We're on at 3pm EST / 12pm PST on Friday, August 21st. Details here: blog.adafruit.com/2026/07/28/c...

Coming Monday on a new episode: it's the return of @todbot.com! Tod shares how to create your own custom CircuitPython firmware without a build environment using only GitHub Actions. Find the show wherever you get your podcasts.

We don't define the feminist games canon — nobody does! So we asked our contributors to share the games that have shaped their feminism. By @exalclaw.com @amandatien.bsky.social @applecider.bsky.social @nicoleclark.bsky.social @candemald.bsky.social and @saoirsestone.bsky.social!

July marks @adafruit.com #FruitJam 's 1st birthday! I've been having a lot of fun creating projects for it. There are tons of things you can do with it, including programming it with @circuitpython.org . Here are just a few examples (incl. my Zork game emulator): learn.adafruit.com/search?q=fru...

Catch a new episode this Monday! Here's a clip of @todbot.com sharing @smallrun.bsky.social, a new selling platform for makers, and one of his favorite features:

I want to boost this again and specifically highlight the fact that this is entirely open source, including detailed schematic notes on the design and component choice. It's a brilliant piece of engineering that gifts so much knowledge to the world.

WIP on #ColecoVision cartridge reader shield for the @adafruit.com #FruitJam: Success! PCBs arrived, parts soldered and initial cartridge reading @circuitpython.org script works! (I can see the game title in the raw data.) Next up is enhance code to write the cartridge data to an SD card.

STEP 1: Dismantle Atari 2600 cartridge.

why would you emulate your sports drink in software when you can instead use a Field Programmable Gatorade?

I live this! Cartridges make me happy.

See, you could get DuPont cables from Digikey, or you could get Dubang cables from E-Simpo. The choice is clear.

Catch Tom on this coming Monday's episode of The CircuitPython Show!

It's been 6 months since I released Zork for the @adafruit.com #FruitJam . If you own a Fruit Jam, you should definitely check it out. If you don't own one yet, Adafruit just released a bunch in their store today so you can buy one. www.adafruit.com/product/6200

SerialPlotster! I miss the Arduino serial plotter when doing CircuitPython / MicroPython, but it's too greedy with the serial port. I wanted a tiny stand-alone data plotter app, so I built one (w/claude's help). It's pretty flexible on data input and fast to launch github.com/todbot/Seria...

I'm delighted by the resurrection of Neo Geo AES using re-engineered ASIC chips (not emulation or even FPGA) and it'll include analog video out + "low lag HDMI". plaionreplai.us?country=US

Another stupid MacOS 26 Tahoe change making my life harder. In Tahoe, several USB tools I use are broken. They call `system_profiler SPUSBDataType` internally to get USB info. In Tahoe that's gone, replaced by "SPUSBHostDataType", which returns not enough info #macos #tahoe #USB #macos26

I had a fun time chatting with the lovely @paulcutler.org for the latest episode of his excellent Circuit Python Show podcast! Check it out here: www.circuitpythonshow.com/@circuitpyth... or wherever you listen to your podcasts. Thanks Paul!
