Frame Drum, analog drum/percussion module for Eurorack systems

Frame drum is a eurorack 4 channel pure analog percussion instrument in 8hp. It is based on the Gamelan Resonator concept first utilized by Paul Demarinis in his ‘Pygmy Gamelan’ pauldemarinis.org/Circuits.html . I’ve been kind of obsessed with it …

Four inputs drive 4 resonators which can each be switched between two pitches (or flatted vs. resonant tone). Each input can be taken out individually or a mix taken out. In practice, the deepest bass needs to be taken out separately since it's too weak in the mix. The resonators are fixed to two possible pitches each. For the adventurous, one can solder on more capacitors to get different tones :)

You can find some more information at which demonstrates some of the features. This is also open hardware and as such you can find design documents and produce your own if you would rather DIY ... github.com/poetaster/frame

The top panels are pcb material but top and bottom are copper filled. So they are almost as stiff as pure aluminum.

The unit is 8hp wide and 6hpdeep.

Power consumed on +12 is approx 30mA.

Includes a power supply cable.

I made these for my own use, but always make more, since buying materials for only 2 units makes no sense. So, these are the overage out of my production for my own use.

#USA Important! message to buyers in the United States of America.Due to a recent executive order issued by the U.S. government, customs regulations for imports into the United States have changed. Private senders can still send gifts to private individuals valued up to $100 per shipment and documents via regular postal mail to recipients in the U.S. and the US customs territory of Puerto Rico. Please make sure that:

- the total value of goods does not exceed $100 / €85

- the contents of the shipment are clearly marked as “Gift” accordance with U.S. import regulations, or as "Documents” if applicable.

Due to the new U.S. customs regulations, sending gifts valued over $100 or commercial goods via regular postal mail is no longer possible until further notice. In such cases, both private and business senders can use DHL Express via the DHL online postage service for shipping. You can find official U.S. government information on the background of these changes here (Executive Order) and here (Fact Sheet).
