The Bleep Drum is back!
The first batch has sold out but I’m taking orders for a second, this time with the option for a fully assembled device. Orders will ship sometime in August.
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.
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)
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.
