Putting Every Chiptune Ever In An FPGA

Finally one device combines the power of the Commodore 64 SID, Atari ST YM2149, and Amiga MOD audio into one awesome box. It’s called the RetroCade Synth, and there’s a Kickstarter that is perfect for starting your chiptune composing journey.

[Jack]’s RetroCade synth is connects directly to the Papilio One 500k FPGA. All the classic chiptune ICs can be emulated in this FPGA including the Commodore 64 SID chip, and an Amiga MOD player. Being a follow-up to [Jack]’s previous FPGA YM2149 project, he also threw that chip into the project for good measure. While the RetroCade doesn’t ship with every old chiptune IC – there isn’t support for NES, Atari, GameBoy, or SN76489-based chiptunes yet – that is something [Jack] will add once the Kickstarter is completed.

After the break you can see [Jack] jamming out on his RetroCade project playing a YM2149, SID, and Amiga MOD sounds simultaneously. For $100, it’s comparable to the venerable MIDIbox SID, but also allows anyone to play whatever genre of chiptunes they desire.

Cardboard Kinetic Creatures

Browsing around today, I saw this little kit on kickstarter called Kinetic Creatures.  These flat packed models are made from cardboard and can be assembled without tools. Their mechanical legs are operated either by a simple cam that you turn by hand or by a motorized attachment. I love the basic idea here. This is the kind of thing that my 6 year old would really enjoy doing that also serves to get him into making things (he’d probably insist on motorizing it with scraps, he collects dc motors and has quite a collection).

I did notice that they mentioned using it as a robotic platform, adding custom electronics to the empty space allowed in the body of the animal. This initially got me quite excited, thinking that I could, for $30 have a 1 foot tall quadruped platform that looked awesome, then I realized it can’t turn. I guess I’ll have to hack it a little bit to put separate drives in for each side. That would be a cool upgrade they could offer.

Have any of you tried to do turning with a set of only 4 [jansen] legs before?
