Codepope’s Development Hell

So, something short to update folks. Circle 1 - Hacking on MQTT, Go, Python and Swift I’ve been currently playing with a polygot project with MQTT. It started with the MuteSync, a button which is wired up with software to mute all your conferencing apps at once. Well, it’s neatly done but I always like to hack into things to make them work more like I want. And actually muting is overrated for me.

So, 2022 eh. Better start doing something here which you may want to read. So this is Circles, a weekly round up of things on my radar. This week, some physical Pi hacking, waiting for a 2.5Gbe PC, some Swift coding, 3D printed stands and a site to check the Prime Ministerial status… Pi hacking (Circle 1) Over the festivus and merinium, I was doing various bits and pieces. The one I’m oddly proud of is also the hackiest.

I was going through the drawers in the lab when I happened across a Kim Uno that I’d put together a long time ago. It’s an Arduino Nano emulating the 6502 at the heart of the Kim-1, one of the classic early microprocessor machines from the late 70s. The board is super bare bones, and with the arrival of a Flashforge Adventurer 3 it was time to get exercising the new printer to make the Kim Uno more finished and all boxed up.

So, what do you do with old Pi projects? I had a Pimoroni Keybow on the side and thanks to RedRobotics’ tiny Pico2Pi board, I had the chance to breathe life back into it by replacing the controller board. Drawing back the Keybow Back in the day, the original Keybow was an interesting little beastie. A 3x4 keyboard of clicky switches with RGB LEDs as a compact keyboard; add your own Raspberry Pi Zero underneath and use a bare metal Lua implementation to configure the keyboard to send codes.

The Dazzler boards have arrived in my Development Hell. These boards, from James Bowman’s Excamera, are a continuation of the Gameduino family of devices which strapped a GPU and a Touchscreen to an Arduino to make a more than functional, graphically rich hand held games device. With the Dazzler, James has taken the Gameduino-3X GPU and moved it to a standalone board which also has an FPGA programmed up to manage more of the work and generate an HDMI signal.
