Thank you for your interest, but I stopped selling on this lovely platform. Most of the designs are open and I'm happy to answer any questions here or even better on twitter.

Inspired by the Logic Noise tutorial by Elliot Williams on hackaday.com, I created a sequencer box that made quirky noises with CMOS 4000 logic chips. The joy of people twisting the knobs at faires for makers and a public interest made me design this minimal PCB.
The CD4028 makes this stand out from 4017 based sequencers, as it is possible to go forwards and backwards. When you set the IC to count to 10 instead of 8, the first and second steps are getting played twice. For every step you can set a tone or a modulation of a synched tone, depending on the sync mode of the board. The board is 2.9 x 0.8 inches in size, so easy to hide away in a box with many knobs.
You will receive the printed circuit board and all the SMD parts (plus headers) needed to populate the PCB directly from aisler.net. Because of recent changes in shipping laws and to hopefully make selling and sharing projects easier for makers in the future, we are working on this together. Think shirt production company where you upload your design and customers can order it, but for pcbs.
This is far from an all-in-one kit, since you need to buy extra components to make it work. People tend to buy the following parts from different sources, some order ten packs from China, others prefer to order quality components from distributors. To keep the price of this kit minimal, I left them out so everyone can buy them on their own terms. Be aware that the values of the potentiometers are important, as the resistance range and the fixed capacitor form the frequency.
You need to buy these things separately:
