Yooo everyone, I've been dipping in and out of the chiptune scene, but I'm working on some nifty new products.

The big one is my new Super MIDI Boys. Back in 2014-ish I modded a SGB with an internal ArduinoBoy. It was something I hadn't seen anyone else try, and to this day I have yet to see another. A few weeks ago I grabbed a couple of SGBs from the local retro game store and stepped up the design of these new ones with:
-Internal ArduinoBoy
-DMG Link Port
-1/8" & RCA ProSound
-1/8" Analog Clock Sync Output
-Variable Clock
-Clock Speed Fix

It features my new ArduinoBoy kits, the other mods were made from scratch, no kits. I'm very pleased with how it all worked out.

I don't have a home computer at the moment, so all pics/vids are hosted on my Instagram account (@UncommonElectronics) for the moment. I'm planning to upload multiple demo vids to YouTube, as well as post finalized product pics asap. Both of the new Super MIDI Boys will be available on my site very soon. www.bigcartel.uncommonelectronics.com

Any news on this? I would probably go in for a preorder.


I'm currently working out some bugs in the code for the 2nd revision, but I may go ahead and release the first rev in the meantime since it works and can be retrofitted.

Any word on this? I want this type of thing. I have been a good boy this year.

I have pretty much finished the redesign. Replaced the 5 mode LEDs with one RGB LED, found a smaller power button, and added gnd and power planes. Right now the main showstopper is simply the funds to make a production batch. I plan to make a small sample run next month (hopefully...) and if all goes well, I might take preorders to expedite the process.

Lol good call, I sent the admin an email and got a response in an hour that said they are indeed still selling them!

Saw that mssiah.com has mssiah carts and sid2sid pcbs labeled as in stock. I'd like to order them, but I'm a bit worried the site may be at the WayFar level. Has anyone ordered from that site recently?

Cool, but you may want to reconsider how you describe that power indicator mod... especially when in all caps! wink


It deserves all caps and four exclamations, if not five, because that's the mod that makes this NES stand out. The power indication light emitting diode enhancement modification isn't something you see every day.

I've been working on this project for a while now.

It's a NES with a Gameboy DMG installed with a bunch of other crap. Intended to help develop some stuff.

NES:
-50 pin D-Sub with access to PPU and cart lines for visual glitch effects (via patch bay), audio lines, and various other lines, with plenty of open spots
-NES Stereo Lines (RCA)
-Remote Foot Switch Reset Jack (3/32")
-Disabled Lockout Chip
-WHITE POWER LED!!!!

Gameboy:
-There's a fucking DMG crammed into that NES with the LCD/Buttons mounted up top.
-Cart slot and link port loacated on the left side of NES
-Powered by NES PSU (will power on even if NES is off)
-ArduinoBoy
-Variable Clock
-Prosound (RCA)
-PS/2 keyboard jack



Because, why not?
















I've made some add-ons to this including an Arduino-controlled visual glitch sequencer. I'll update with videos of that soon.

You are correct, the 3rd headphone jack has smt caps and resistors (along with it being a switching jack) so that it can be a filtered ProSound output. And the final design will have ground planes on each of the boards for increased interference reduction.

FYI those aren't resistors on the filter board, they're inductors.


Oh wow, looking back at the schematic, you're absolutely right. Luckily it shouldn't be hard to find inductors with a 0805 footprint. Thanks for the tip!

Will you include some paper overlays that show the DIY'ers where to drill?

The final kit will include drill guides, wiring diagrams, and installation instructions for both DMG and SGB. I will also provide instructions for programming the ATmega so the AB code can be updated/customized if needed.

Looks awesome. Whereabouts in the DMG is it designed to fit?

The LED board goes up top above the LCD and the ATmega board goes in the open space on the side of the battery compartment beneath the speaker.

Howdy everyone, I've been lurking in the shadows for a while, but I return with something nifty.

I've familiarized myself with Eagle CAD for work, and have spent a while working on an internal ArduinoBoy kit. It's designed to fit in DMGs and SGBs. On-board flashing to the standalone ATmega328p. 1/8" Stereo Jacks for MIDI In and Out/Thru, along with a ProSound headphone jack. Final design will include an optional USB for MIDI.

Update 2/23/17 -
Sample PCBs of the new revision have arrived. I worked on this new rev for months and made quite a few changes. I completely started from scratch on the PCB layout for each of the 3 PCBs, rerouted everything, changed parts, and added a couple of new fancy thangs. I modified the ArduinoBoy code to replace the 5 mode LEDs with a single RGB NeoPixel that only requires one data line (along with +5V & GND of course), cutting down the number of wire connections needed between pcbs.
I also added Variable Clock, because, why the fuck not?


Successfully burned the Arduino bootloader to the ATmega328 and uploaded the sketch in-circuit through the programming pins (easy to make programming adapter, allowing people to fuck with the code if they want! You do You!) into a DMG today and will be testing in the coming days.

*(Under Construction)*
Hey everyone, I've been a lurker during the last couple of years, but during that time I've kept myself busy with various projects. There's some big R&D projects that I'm working on (mainly NES related), and I'm also still offering custom GameBoys on my new site, www.uncommonelectronics.bigcartel.com.

I will be posting my current and upcoming projects in this thread, as well as updates for my store.

I farted out this thing. It's a hella legit gameboy synth or some shit.
All dem holes are for individual channel volume, clock sync jacks, master volume, midi controls, lskeyj inspired button layout, and a bunch of other excessive crap. It's a long work in progress, but it's gonna be the bees knees.
