I like it better with the logos. Gives it a bit more character. Might see if I can get the apple logo in color. Unfortunately my printer only does 4 colors. And I've already spent way too much money on this project!

OK, got a replacement LCD controller and this one seems much better. I did, however, change how I was powering everything . I now have it set up with a 12v DVC jack as input, split into two buck converters to drop the voltage to 5v. One to power the LisaFPGA and one to power the new LCD...

Started trying to chip away at the USB support, and have something to test, but for some reason I can no longer connect to the LisaFPGA over the USB-C port to push software changes to it. It sill powers up and seems to run fine from the port, but when connected with a USB-C data cable, neither...

I'm hoping to keep it cheaper and people can use a sufficiently rated 12v power supply. I think the 5v controller board that came with my 11.6" LCD is garbage, so I have an alternative controller board coming that is 12v. My plan is to splice the 12v input with one line directly going to the...

You could try grabbing my fork of Alex's repo and installing the version I have that allows you to run 1024x768. The image isn't quite as good as the 1080p output, letterboxed, because the scaling isn't perfect so I had to use dithering, but it would at least get you an image on the Eyoyo...

Well, I tried putting something together today that involved a usb-c breakout board type device, some resistors and a capacitor to try to reliably power the LCD and the LisaFPGA and I think I fried my LCD controller board. :( I may try to get a replacement and go down the route of using a...

Yeah, that’s way better than mine! I like the light pipes, so I might need to see if I can print those and incorporate it into the back of mine. Work has been crazy lately, so I haven’t had time to resume work on this, but I did pick up a K2 Plus printer which can print the case in one piece...

So, I'm not sure if my Color Classic degauss coil / circuit is bad, or if the magnetic disruption was simply too much for it, but multiple cold boots with cool-down time between didn't fix the problem and didn't even seem to make it better. But, I did manage to get a manual degauss coil from FB...

I wish I could take credit. I have zero experience programming hardware via FPGA. I used Claude and guided it to update the HDMI output. Basically the Lisa emulation portion is outputting the standard resolution (depending on the ROM) and I just adjust the HDMI output to shift the output of...

OK, I pretty much have the case design finished, with versions of the front piece for either an iPad 1024x768 LCD or the 11.6" widescreen 1080p LCD. And versions of the back case for either a LisaFPGA or a Raspberry Pi 4. I struggled a bit with my above mentioned LCD location adjustment...

Made some more progress on the case. I think I'm going to try to make two case fronts, one for the iPad screen and one for the 11.6" screen. It should give flexibility. I also posted about this on the main LisaFPGA thread, but I added the ability to control the output resolution at...

OK, I've been working on a 3d printed case for the LisaFPGA - something I could stuff an iPad or similarly sized LCD in and make an all in one, flat screen Lisa. The design is coming along, but the challenge I faced with my original plan of an iPad screen. The good: 4:3 ratio, readily...

Finally got the Logitech M185 in and did some tweaking of my design. It took a few tries but I was able to get it to fit. Still tweaking the right mouse button but should have it ironed out soon (sometimes it seems to get hung up on something). Overall, though, it works well. The two...

I believe it is 3x the original vertical 360 pixels tall, which would be 1080. And 2x wide which would be 1440 (rectangularn” pixels are weird) I spent some time tinkering trying to get it to output 1024 x 768. Shockingly, with no experience programming FPGAs, I was able to get it to display...

I've got some software changes I want to try to make on the LisaFPGA, but it is apparently quite involved trying to compile the software for the FPGA itself, and seems to be something not possible (or at least not possible reliably) on a Mac. I tried an old Lenovo laptop but it was not up to...
