arisoturaNot a lot to say, these days.
Minor update about the vintage radio... I was looking at the mystery tube (the one with no markings) and it seems to be an ECH81, or something close. There's an actual ECH81 in the radio, and the construction inside is very similar. I don't really have better ways to tell, though.
I'm still waiting for the correct tubes to be delivered to me, so not much else to say. (amusingly, just as I'm writing that, I find out that my order has been shipped, so it should hopefully arrive soon!)
There are other possible projects with the radio. One of them would be fixing the missing button, which would involve some 3D printing and a bit of cleverness.
I spent some time getting measurements for another hypothetical project, too. It's about the WiiU gamepad.
Basically, the gamepad has a debug serial port, which can be used to boot code. The issue is that it's kind of annoying to use. My idea is to make a small PCB that would replace the expansion port, but have an USB port and a switch for UART boot. The PCB could feature an USB-to-serial chip (FTDI or whatever), which would be wired to the debug serial port.
Maybe with clever wiring this could also enable USB charging. I don't know about running the gamepad off USB power, though. The gamepad doesn't support that, so that would probbly require modifying the UIC firmware...
Regardless, PCB design and 3D printing are things that fascinate me, and I want to try someday. This could be the occasion. It doesn't seem very complicated.
Speaking of WiiU gamepad, I started porting lolSNES to the gamepad, as a fun demo of what is possible. I even had the idea of using the wifi card's CPU to assist with PPU emulation. I did manage to get code running on that CPU... I just haven't worked on it in a while. The usual ADHD stuff...
I also have ideas for melonDS, but ADHD gets in the way too. Same problem, the barrier to actually starting a project, the amount of effort that needs to be invested before starting to see something...
Other than that, therapy is underway, the usual. I have a "skeptic" part telling me that it's fake, but the experience I've had the last time tends to confirm it's very real. This is something I could write more about, in a dedicated post...
