Gameboy Analog Sync Adapter
This is a simple little analog (CV) sync adapter for use with LSDJ and Nanoloop on a Nintendo Gameboy. The 3.5mm jack can be used as either an input or an output, selectable with the on board switch.

I've launched a new site! Instead of living on my personal site, the shop now has it's own place! http://catskullelectronics.com/
To celebrate, I'm offering 10% off everything until March 5. This is seriously the only sale or discount you'll likely ever get from me, so take advantage while you can!
Arduinoboy kits from $16
Frustrated by the limited availability of Arduinoboy kits and the high cost of those that are available, I've produced my own.
Prices are as follows:
Unassembled kit: $16
Assembled kit: $26
Arduino clone: $5
Shipping CONUS: $5
GBC link port for easy use with a dual DMG/CGB link cable.
Headers for MIDI jacks and screw terminals for those that want to put it in an enclosure.
Three power options: gameboy 5v, Arduino USB, or Arduino 9-12v wall adapter.
100% through hole for easy assembly.
An arduinoboy for $16!
NEW! Revision 1.0.1 fixes the link port pinout issue on the last batch.
I've priced this as low as possible so I'm not looking to make a fortune here, I just hope this will get arduinoboys into more hands.
More details and purchasing is up on my shop at

I've been a little bit frustrated with the lack of a good ready to buy Arduinoboy kit. The only US based seller I'm aware of is Xiwi, and it seems like he no longer sells them. The idea is to get an easy to assemble PCB, and all the various parts and sell them for as little as possible.
Here's what I'm looking at right now:
"Shield" Kit (unassembled, no Arduino, no link cable): $15 shipped
Image for reference only
Pro Mini/Micro Breakout Kit (unassembled, no Arduino, no link cable): $15 shipped
image for reference only
Add an extra $5 for an Arduino
Add an extra $10 for assembly
Add an extra $4 for 1/2 of a link cable
That would total $24 for a kit unassembled or $34 for a ready go to aboy.
So my question is, would anyone be interested at that price point? If not, is it too expensive? Am I an a-hole for even considering selling arduinoboy's?
Have you ever wanted a dedicated cart for all the random music roms you use? Things like mGB, shitwave, and death ray?
Soon, you’ll have the option.
How much will it cost? $10.
Stay tuned for more details.
The boards finally showed up! Just waiting on a few final details before they go on sale. In the meantime, here's a quick demo video I made to show it off!
Super simple PS/2 adapter
Here's a little thing I've been working on. It's just a super simple (and cheap) PS/2 adapter for a DMG.
The video says it all:
What do you think about it? Stupid? Cool? Boring? Let me know!
min64: A tiny Commodore cartridge
I'm happy to announce that the min64 is now for sale! It's tiny! The idea is that you can leave it in your Commodore all the time. Oh and the best part? It's only $10 with a flashed ROM!
Limited quantities available, so order sooner than later!
There's not a whole lot to say about it really, just a little eprom cart.
Thanks to Jazzmarazz!
Interest check: MIDI thru box with channel manipulation
I just wanted to see if there was any interest in a MIDI thru box that's capable of adjusting which channels the data is sent on. Here's what I'm thinking:
One MIDI input
Four MIDI outputs
Each output will be able to select which channel it outputs on. So say you input on channel 1, you could have the through box output on channels 2, 3, 4, and 5. Or, you could leave them all on the same channel it came in on, 1.
A MIDI panic button. Kills the note on all four outputs.
That's basically it. How does it sound? Are there any features you'd really like to see it have? Does that sound dumb? Let me know!
