Vibe with the Feather RP2040 video synth
The Feather RP2040 and a FeatherWing Proto sit next to each on the FeatherWing Doubler. The potentiometers and buttons are wired via the FeatherWing Proto. This nice show-and-tell will help you do the wiring. The Feather RP2040 powers everything via its USB port and runs Arduino code from the PicoDVI library. All the project code is up for grabs here.
There are five animations coded onto the video synth. Twiddle the potentiometer knobs to alter each animation like a visual DJ. Three of them adjust the colours, and one changes different visual aspects depending on which animation is playing.

Messing with the Beepberry
The keyboard feels almost as good as any old Blackberry, though it doesn't have full support from behind—I think a good case design could provide a tiny bit more structure behind the left and right side of the keyboard. The center keys feel great, the outside keys have a tiny bit of flex to them. Ctrl is mapped to the little 'pick up phone' icon (which looks more like an empty bowl to me), and you can hold down the 'hang up phone' (the park bench on the right) to safely shut down the device. There's also a power switch on the bottom.

How I Hacked my Car Part 6: Nothing to it but to Doom it.
There is a long standing tradition among hardware hackers and tinkerers. Once a platform is hacked, once a gadget is tinkered with, once a device is understood there will always be someone who asks a certain, specific question. And that question is: “Can it run Doom?”
