Scribbles is a handmade synth with a chalkboard.

My friend was showing me some neat synthesizer ties on Etsy. For those who don’t know Etsy is a great site where people sell their hand made goods. I decided to search further on the site and see if there were any handmade electronics for sale and I found Scribbles. This hand made synthesizer has a most unique feature: a built in chalkboard!

The synth is based on Ray Wilson’s Sound Lab Mini-Synth design which you can find at

The oscillators are tuned to 1V/octave, so it will track with other 1V/octave keyboards. There are inverting level shifteres on the ramp oscillators, and a sawtooth wave output on each. There is an additional square wave output on VCO 2. One of its special features is the pre-amp on the main output- you can listen to Scribbles on your headphones.

With the Sample & Hold, you can play melodies that sound like a sequence and is especially fun to play with the LFO’s triangle wave as its input source. With a square wave, the result is more calculated and more random sounding, depending on the pulse width and sample rate. The Attack-Release envelope generator has an internal loop option, which makes it repeat and play like an LFO too. If you switch the loop switch down, the envelope generator repeats on the Sample & Hold. The blue arcade button on the corner is a manual trigger button for the envelope generator. Adding to the main output’s pre-amp, there is another pre-amp on the audio input, which turns up the volume but can also make distortion. And to add to this mix of making a variety in tones, there is another pre-amp circuit after the filter, but before the VCA. –

The Scribbles was listed on Etsy for $380 USD. I believe it sold since I saw it last night because I can’t find the listing again. Luckily I remembered the website mentioned in the listing so you listen to some MP3 samples: If your in the spending mood you can see if they are making more for sale. Oh by the way while you are there check out their Swing Step Sequencer: niiice.

What would you write on the Scribbles chalkboard? Patch ideas? Lyrics? Inspiring quotes? The grocery list?
