Jasper Construction Guide, FAQs to follow. The original thread is here: viewtopic.php?t=151625īOM, PCB and Panel measurements, Enhanced mode PCB construction guide are posted below. This is the build thread for the Jasper, EDP Wasp clone PCBs.

Or at least it shows how I make up the PCB. The construction guide is quite large, and illustrates the construction of the PCB and panel set. I built a PCB just using the silkscreen values, not referring to the BOM at all and everything works fine.įinally an updated build guide attached below covering the second version PCBs!įor the second PCB run, an updated BOM taking in account the differences between the second version and Jasper from the first run.įinally completed an initial version of a construction guide, and a FAQ document. It doesn't affect the operation of the rest of Jasper - which still sounds great. If you're not using the 3.5mm jacks then this is academic anyway. I've attached a note to this post describing the issue and fix. It's not obligatory as the amplified 'phones output is designed for older style high-impedance phones or equipment needing higher input levels. It still works, only affects the 'phones output.Ī fix is easy, if you wish to do it. So when a stereo cable is plugged in, signal is only output on one channel, not both as intended. A very simple change to swap the speaker output to the centre pins on the socket. Anyway the 4th run PCBs are ready to be shipped.Įssentially the PCB is the same as the previous versions - but I wanted to update the silkscreen to match the current BOM.Ī Mea Culpa - I was also tempted to adjust the 'phones out to enable the use of mono Cliff jack sockets as well as the stereo ones used. 25 January 2017 - 4th run PCBs - ready to ship
