Please note: this listing is for people who want to do the AstroNoise workshop at Knobcon 2016. If you want to purchase the AstroNoise kit and have it mailed to you, check it out here.

Knobcon 2016 bonus! The AstroNoise at KC can be built as a Eurorack module OR as a standalone circuit that you can wire into a case later. In the past it has just been a standalone circuit, but the lofi wizards of Synthrotek have modded the board to fit in a 10HP DIY Blank Panel. All kits will come with the parts needed for both the standalone circuit or Eurorack mod, no extra charge. The PCB will be cut ahead of time as needed for the mod, and the DIY Panel will be pre-drilled. The jacks provided will be 3.5mm.

The workshop will be taught by Scott Rise of Division 6 fame. Soldering irons, solder, and other necessary tools will be provided. You can check out the assembly instructions ahead of time here (the Eurorack mod is at the bottom of the page). 

This circuit requires a medium-ish skill level. Have you soldered something successfully before? Then you're good to go.

Please purchase this workshop ahead of time so we know how many kits to bring!

Info on the AstroNoise:

The AstroNoise is a massive vintage video game-inspired noise-making machine! Shape the galactic frequencies with 4 onboard controls. The "Oscillator Rate" controls the master frequency. The two LFOs and the LFO pitch modulate that frequency and together allow you to make rhythms, video game motorcycle sounds and more.

The AstroNoise whets your appetite further by letting you choose between 3 different radical vintage tones. The adventurous user can use it to make beats, lead lines and noise swashes by connecting other devices into the LFO input and the Control Voltage input (optional). The fun doesn't end after building the circuit! Take your creative skills further by designing your own custom enclosure out of an old cigar box, lunch box, doll head, etc!


  • Tone Select Switch lets you choose between three classic sounds: bleeps and bloops, 8bit explosions and razor-edge squares
  • Oscillator Rate Control ("Rate" on the PCB) changes the master frequency and rate
  • LFO Rate 1 Control (OSC1)
  • LFO Rate 2 Control (OSC2)
  • LFO Pitch Control (OSC_LVL) 
  • Volume Control 
  • Oscillator On/Off switch (turns off LFO Rate 1/OSC1 and LFO Pitch/OSC_LVL)
  • LFO Input (OSC_IN): use for external control of LFO Rate 1 with an input of 1-150 Hz
  • Control Voltage (CV) input (disables LFOs)
  • Power on/off switch
  • 9V DC jack and battery clip
Please note: The AstroNoise takes 5 seconds or so to warm up when turned on. If you don't hear any sound after a few seconds, toggle the tone switch back and forth a few times and it will come to life. This only happens when it is first powered on.
