Jasper Synth - EDP Wasp Clone + desktop stand

I finished another Jasper Synth (EDP WASP clone). For this Jasper I'm using a slightly re-designed 3D printed case which fits into a desktop stand. For the first time I'm using PETG instead of PLA for the case. PETG is a bit more flexible and not as brittle like PLA printed items. (link: PLA vs PETG) The Japser comes with MIDI IN and OUT and the switch for 2 different "hold" functions. The Jasper enclosure is 3D printed (glued together) and consists out of the Jasper enclosure and a desktop stand with a wooden element. The Jasper is ready and fully functional but I'm currently waiting for a shipment of screws to finalise the assembly of the casing. The wood on the photo will get a finish with hard oil wax.

Jasper Synth

The Jasper Synth is a clone of the EDP Wasp synthesizer that was made by the small British company EDP (Electronic Dream Plant) for a few years from 1978 to 1982. Credits to Jason from jaspersynth.co.uk.

The Wasp was one of the first commercially available digital/analogue hybrid synthesizers. Designed by Chris Huggett and Adrian Wagner who created it as an affordable synthesizer using the then newly and widely available inexpensive CMOS digital logic chips.
