Took a bit to figure out but i reckon this is a goodish way to gauge speed.

Oh yeah. Much faster. Reckon itd be even faster if using PIO to stream commands and data in.

Thinking on the next revision of my conbadge atm... Wonder if i should add the df player mini to it to add music capabilities. There are spare pins on the pico for uart.

Mistakes in code here and there, fixed =~=

Lcd arrived. Porfed testcode for it into fhe arduino ide. Works! Though i needed to bodge the backlight control. The distance between it and the board concern me a lil. Need to look into it to design a sort of spacer.

MS Flip Flop using the CMOS logic gates I made a while ago. Since it works, time to make a PCB with it all in one :p

So close to getting my Otter x16 somewhat luggable...

Is there some sort of list of popular and cheap components that hobbyists tend to use? I need to find power mosfets, both p and n channel, that can do 1a at least, whilst in preferable sot-23 or to-92 packaging. And probably able to be bought in bulk on aliexpress.

Ok so, I hooked up my inverter board to the wave generator on my scope. It's alot faster than I thought. Adding a capacitor across the power rails made it significantly less noisy too.

Seems like the rise/fall times of my CMOS inverter is slow at about 800us. Should mean I could only run them just above 1khz. Ah well.

YESSSSS

Agnus. Transforming Protogen design. Will have to polish her up soon.

Nand gate soldered and tested. Works!

Proved to work with the inverter.

Status LED works.

More of the boards arrived NAND and revised NOT gate are good, though I just realized the footprint I used for the led module is... Not the handsolder one. Balls.

I wonder if its possible to build a 65c816 computer on par with the C128, but with 74xx/4xxx logic... already trying to make a VGA card, once that's done its just the Sound, Peripherals and the chipset itself...

@popeyeotaku.bsky.social Yessss
