I got a Bambu X1C and did some test prints of the dock shell. Ended up adding a ridge alongside the Kawaii and tweaking the internal mechanics a bit. Then I started working on testing the internal Kawaii PCB! I ordered the wrong size level shifter, so I'm unable to test the addressable...

Sorry to hear that! @Teatimetim had a similar issue and it ended up being a wiring mistake. Gotta be the case here. Some things to check: Triple check the pinout of your controller cable with a continuity meter. Each one has different wire colors, so you can't trust online pics or guides...

Quick and dirty 1200DPI PSOne PM-41(2) motherboard scans. The existing scans from the PCB Strip Club had scaling issues. 7964x6292 TIFFs and PNGs are included. GOOGLE DRIVE LINK BITBUILT MIRROR LINK

I'll DM you!

Hey man! Glad you're getting on the MaplePad train. It's super simple to program the Pico. Go to the Releases section on the righthand side of the repo. Download the maplepad_v1.5.uf2 file corresponding to the controller type you want: standard for HKT-7700, or arcade stick for HKT-7300. Hold...

Thanks, dude! That one was hand-soldered (T15-BCM2 for AVE and T15-JS02 for passives). I hit it with some SMD291 and hot air afterwards to get everything shiny, then threw it in the ultrasonic cleaner for 10 minutes.

The ninjas can't stop this portablizer! I received the anodized aluminum prototype shells from @Ding earlier this month. In person, they actually look better than the renders. The pogo pin connector slots into the shell like so. It's held in place very securely. I also received the...

Don't buy from Wisecoco, they charge a ridiculous amount for the 3.5" 640X480 LCD. Also, not all the driver boards configure the 3.5" panel the same way, so buying a standalone driver board is risky. You can get a full LCD + driver board combo for 28USD here...

The 12v regulator PGOOD can easily be bypassed (as seen here). The issue is that the two core regulators are designed for 9V - 18V input: This is very normal for wall-powered devices. Computers use the 12V ATX rail to feed their VRMs, too. Using a higher voltage like 12V means the power...

I have confirmed that both of the custom modelines work perfectly on PS1. The 3.5" LCD is difficult to photograph. Hopefully the sharpness comes across in this 4K recording. The motion clarity and crispness are truly unbelievable. Close-up of scanlines on the 3.5" LCD: 800x480 LCDs also...

I have an update regarding a minor "bug" @loopj and I have noticed with Thundervolt. The risk to end users is low, but just to be extra safe, I have released new board revs and firmware to address the issue. ~ During Thundervolt testing, I noticed some strange behavior with the U10 emulation...

GCVideo DVI already outputs 480p HDMI, but you'd need to adjust the reblanker to output the 800x480 modeline the LCD requires, and probably tweak some other stuff, too. The Xilinx toolchain is pretty nasty and I wouldn't recommend going that route. Fujiflex uses 1.8v to power the FPGA 1.2v...

You bring up some good points! Hopefully I can clarify some things and answer your questions. Direct Drive does have quite a few benefits over GCVideo DVI (FujiFlex) plus an HDMI driver board. The big one is power consumption: DD draws ~350mA @ 3.3V (1.15W) A typical RTD2660 driver board...

I received the Kawaii PCBs in the mail this week. Just waiting on some components to arrive before I can begin assembly. And here are the latest photos of the laser engraved shell, courtesy of @Ding! Looks just like the renders Next steps include trimming some OMEGAs, assembling and...

Yup, that should work!

The sensor bar GND is PWM'd (pulsed on and off) to limit the current through the LEDs (this is called low-side switching). Early sensor bars have more LEDs (5 per side) and need the ~7V or so that the motherboard's circuit provides. Later sensor bars only have 3 LEDs per side and can run from...

I'm a little wary of messing with the video levels in case it impacts the colors or contrast. But I found a workaround for now. Increasing the backlight current by ~1.75x makes the brightness in scanline mode good enough. The stock boost converter is unhappy outputting this much current, but...

My 2X-SCART arrived! I like the silk labels for the input pins. The PCB has a couple mystery ICs; one seems to be an LM1881, and another is probably a THS7374. Not sure what the others are yet, but it'll become clear once I generate a schematic. The FTDI chip can definitely be yeeted once I...

Quick and dirty scans of the HKT-7700 Sega Dreamcast controller PCB. The existing public scans were not a known DPI and therefore unsuitable for reverse engineering. GOOGLE DRIVE LINK BITBUILT MIRROR LINK Folder includes 1200DPI TIFs (6629x4157px, 80MB each) and 600DPI JPGs. Preview images...

This stuff is really challenging, but you make it look trivial! Awesome work. If you want to be extra safe, you can also tie Wi-Fi pin 9 to 3.3v, the way Cafeflex does. Just to ensure it's in the correct state.
