Gecho and Friends
Gecho is a collaborative lizard
Kickstarter has been fulfilled, shops open and recently sold out as I've ran out of certain material. There are still some boards left so the plan is to re-open early next year.
This allows me to get back to expanding the firmware for the time being. The list is quite long, but one feature that you guys were asking about a lot was syncing with other devices. I'm starting experimenting with my humble but growing collection of prevailingly DIY synths, most of them have some kind of clock input or output.
The results of this effort will be demoed and published on my channel.
Please shout if you think something is missing here, a device that will feel at home in this companion, I've actively hunted these for months but there must be more of them hiding in the depths of the Internet!

Yowler is sadly missing from the picture as I've misplaced it somewhere. There are also simpler boards from eBay - FFT matrix, ICL8038 oscillator and NE555+CD4017 driven "sequencer", and some new pieces we will talk about later - stay tuned! :)
