The Edison is named after the well-known scientist. Now you might be looking at the module and wondering what the link is to the scientist but Edison is the man who patented the Phonograph, a device that could be used for the recording and playback of sound, just like this module! You can record audio into the internal recording buffer, via the built-in microphone or the jack input, and play it back. It's a 6HP-wide module and is built around the ISD1820. It can produce a wide spectrum of sounds ranging from tasty lofi to absolute glitch fests.

All SMD components are already soldered onto the board. To finish the build, a number of components are required:

• 6x Thonkiconn mono jacks
• 2x 100kOhm potentiometer
• 1x 3mm LED (color of choice)
• 3x sub-miniature toggle switches
• 1x 2x5 pinheader (for eurorack power supply)
• 1x ISD1820
• IC socket for ISD1820
• 1x electret microphone (make sure to buy one with long enough leads, in order to mount it level with the frontplate)
