I found this board had poor video quality, but Olimex make a compatible FabGL board which has much better video output.

It’s become a favorite for friends to play, everyone loves that dart board. And considering I paid like $75 for it. ;-)

Ah, good to know, I thought I saw it somewhere at one point but I’ve never used it, good to know it works. It’s a great little project, I recently came in possession of the MT-32 Librarian/Editor software for the C64, on floppy, and really want to see if it’ll work against this.

I like this, but I am allergic to the idea of using an entire computer (the ESP32) to do something so trivial. (If you're going to use a complete computer, just use a computer, you know?) This seems much more like the kind of thing where an FPGA would really be ideal, though an FPGA would certainly not be cheaper or easier to implement. It really feels to me like an FPGA is the right tool for this job. FPGAs handle RS232, VGA, and HDMI with ease, and can go all the way up to resolutions like 1920x1080 and beyond, though not all the way to 4k. On the other hand, you would probably need to implement a CPU to handle all of the terminal compatibility and features that something like a DEC 525 terminal would support, so what do I know?

@technicallyworking4real 4 ай бұрын

You’ll love the video on using an ESP32 just to turn on a light bulb then. Granted, it’s on a C64, but still relatively useless. Possibility for the sake of possibility is what inspired us to build the Internet.

Very nice project. I wonder if with enough effort, a Pi Pico could pull it off.

@technicallyworking4real 5 ай бұрын

I’d think maybe, especially via USB, and not using a standard MIDI jack. Much of the PCB deals with the 5-pin DIN MIDI interface, the remainder are basically pass-thru for the DAC and OLED. The only part I’d wonder about is if the base image handles the architecture of the Pico. I might give that a try and see, think I have some left around and a USB hat for them.

It's too bad it's not easier to do the reverse of this (ie. VGA-to-serial). Anyway, pretty cool! Pine died some 20 years ago and mutt took over. Then there was Alpine but I stuck with mutt even though I preferred Pine. They were all relatively dead anyway once webmail and HTML made it so difficult to use old-school mail clients. I still send text-only even from web clients, ha.

@technicallyworking4real 5 ай бұрын

Wow, thanks a lot for that, I tried to “get to the point” as much as possible so others could get something out of it quickly. I’ve been using it for a while now, having a dedicated terminal sitting there is massively helpful, especially one that you KNOW works. I’ve since put 3 of them on a small KVM and hooked up an old serial switcher to one so I can bounce around between them and various inputs. You know that old manual RS-232 switcher we all had years ago? The ones we all said we’d never need again? Yea, one of those. ;-)

One of my first “real” jobs in tech had VT420’s connected, via DECServer terminal servers, to many VAXen, they’ll always have a sweet spot for me. I’m still on the search for an LK-451 keyboard for this one, the 471 there is a decent stand-in, but I really want that Do key. ;-)

I built a battery powered dedicated 'terminal' using the Lilygo board and a MAX3232 for my RC2014. It isn't documented anywhere, but if you attach a battery to the board,, there is a charge circuit built into the board (via the USB socket). One 18650 will power the terminal for days!

To get a color capable console, ensure your TERM variable is set to ansi… ‘export TERM=ansi’ To check, ‘echo $TERM’. You might be able to set the default TERM type in the getty service config.

It really is, the same project, FabGL, has a VIC-20 “emulator” example, I’ve toyed with picking up a VIC-20 case and keyboard and using the ESP32 VGA to build one. Zero useful value other than “this is frickin weird”.

I had heard about FabGL but wasn't aware that LILYGO had a board for that. I've been using and developing a terminal based on the RP2040 and the PicoVGA library, an advantage of the RP2040 solution is support for USB keyboards. Will try to get one of thes LILYGO boards.

Just looking for recommendations.....just find one of these it was missing the power supply I bought a 9v power supply it has power coming in but nothing on the screen. Does it work with just av or does it need rf? The board has power any info would be great thank you

@technicallyworking4real 8 ай бұрын

It’s composite video out, if you have a tv that does composite, it’ll work on it. I started with tearing it all down, cleaning the board, removing all the chips, de-oxit’ing them then putting them all back in. After that I checked all the chips for what they had for Vcc and scoped out the cpu and video chips to see if the signals all looked right. I was able to get signal into a tv at that point, re-assembled it all then found the AC adapter voltage issue. It’s all pretty typical 8-bit stuff inside, the processor, memory, TMS video, etc so similar troubleshooting methods work. Good luck! It was fun, a pain, but fun. Kids love having it around to play.

Thanks for the video. I got mine put together, and it's making sound, but it's there's no overdrive to it. It boosts the amp, but it's like a clean boost. My gain knob seems to weaken the output the more it's turned up. This stuff's harder than it looks!

Sounds like maybe something in the diode clipping circuit section, check and make sure they’re all in the correct direction? And yea, it’s not quite as easy as it looks. ;-)
