The Bleep Drum is back!
Preorder a kit now for shipping in June. (See production timeline below).
Kit includes everything you need to make your own drum machine. All you need is a soldering iron and some tools. No Arduino board required.
This kit is designed for everyone and is a great for learning how to solder.
Full educational materials explaining the code and hardware will be available when the device starts shipping.
This run is almost full. Another one might be done in September. Sign up for email updates here.
New in this version:
– Click track – Hold shift for 4 seconds to turn on and off click while the device is playing.
– Improved stability – Fixed an issue where the sequence could slow down if too much was happening.
– Better noise mode – Greater range of distorted sounds (hold shift while turning device on)
– Easier to solder PCB with better LED.
Upgrade chips are available for older Bleep Drums or you can download the code here.
The Bleep Drum is an Arduino (ATmega328) based lo-fi rad-fi drum machine designed by Dr. Bleep. It was originally sold from 2013-2016, first for Dam Funk as the Dam Drum, then as the Bleep Drum.
– Four sounds, two with pitch control
– Wonderfully crunchy 8 bit DAC output at ~10kHz sample rate
– Available with and without a MIDI input (implementation info)
– Four selectable sequences with 32 steps each.
– Record patterns just by playing them. The built in quantizer keeps hits where you want them.
– Click track
– Tap tempo
– Reverse mode
– Noise mode (expanded in new version)
– 9V battery powered
– “Stereo” 1/8″ output (see “How do you listen to it?” below)
The circuit boards have arrived. Just waiting on a few more parts which should get here next week. If they do kits will start shipping first week of June.
New PCB: Complete and tested
New Code: Compete and tested
Instructions: Underway. Will be completed by the time it ships
Parts: Some can arrive in days, others will take 2-5 weeks.
I made a new version with a much easier to solder and more even LED in 2018 for a school so an updated board is already ready to go. I just need to order it. Turnaround time on that is currently less than 2 weeks.
Most parts are available in the US but a few will take 2-5 weeks to get from China. In the past it’s usally only taken 2 weeks but things are obviously complicated right now. Once I get an idea about how many orders there might be I’ll order these parts. Probably around May 6th.
All the rest of the parts and the PCBs will arrive well before then so most things will be prepped and ready to go.
if things take 4 weeks to arrive from China I will start shipping units around June 10th.
I’ll update this info as things progress.

How do you listen to it?
The Bleep Drum has a phased stereo 1/8″ output. This means that through headphones it will sound nice and huge even though it’s really just a mono signal that’s phase is flipped on the other channel.
To plug it into a mixer, amp, USB interface, etc, a mono cable must be used.
Midi implementation guide here.
The device can receive MIDI notes to trigger the sounds and other options as well as MIDI CCs to change the pitches but it can’t do MIDI clock unfortunately. There’s only so much the little chip can handle.
See this guide. It’s a pretty simple circuit that will allow you to activate the sounds using your modular.
