Mannequins RIP module by Whimsical Raps is now open source. EXI[S]T is an adaption thereof and can be configured in several ways. The name is a tribute to Meng Qi's module "Please Exist".
The main PCB – the transformer board – is meant to be mounted inside the case. The inputs and outputs can be connected in serveral ways. Any configuration of the listed options below is possible.
Input option A:
The inputs are conncted to the transformer board via 16 pin ribbon cable from the 1u EXI[S]T module. The 1u modules are available in Intellijel (12HP) and Pulplogic (10HP) format and house the input jacks, lift switch and an attenuating volume pot.
Input option B:
An Intelligel Mixup module can be connceted directly to the transformer board via the molex 3pin output bus connector. This configuration makes the 1u module redundant and ground lift may be engaged directly on the transformer board with two jumpers.
Output option A:
TRS Jacks can be connected to the transformer board with wires via the "TRS" pads.
Output option B:
The 6pin header can be connected either to an Intellijel Audio Jack rev2 board or an Intellijel Stereo Line Out Jacks module via 6 pin ribbon cable.
PCBs: All eagle files can be found in the repro in case you wish to have PCB's fabricated.
BOM: Here is the OCTOPART BOM. Please note that the silkscreen of the mixup header on the transformer board should be rotated by 180° (rotate the header before soldering, otherwise L and R channels will be swapped). The silkscreen has been corrected on the Eagle files.
Thanks to Whimsical Raps for designing RIP and making the files open source, and to Meng Qi for the name inspiration.
