Projecttitel: DINSYNC RE-303Status:Startdate: 2016Duedate: 09/2018last update : 02/2023Manufacture link: http://privat.bahnhof.se/wb447909/dinsync/re-303/Forum : http://23.235.199.139/~re303c5/forum/ |
The Founder Paul Barker developed in 2016 the RE-303.
the "internal Name" is Space Cadet.
few different case types are avaiable/fits with the pcbs: TT-303 (old version),
you find a german article from me, about the RE-303 here:
https://www.amazona.de/test-din-sync-re-303-die-beste-tb-303-ever/
RE-303 v1.2 main-board and switch-board PCB.
Sumida coil and adapter.
3pc set of power transistors.
8pc set of potentiometers (tune, cutoff, resonance, env, decay, accent, tempo and volume with switch)
2pc set of rotary switches (pattern/mode)
3pc set of 6.3mm jacks (mix in, headphone, main out)
2pc set of 3.5mm jacks (cv/gate)
1pc DC jack
1pc waveform switch
Parts what you have to source:
the following files are based on the same version but with different office formats:
MOUSER BOM project card: https://www.mouser.at/ProjectManager/ProjectDetail.aspx?AccessID=0324e99177
plus tactiles: 688-SKQEAA
ift(y): yellow coil for the original cpu clock |

ID | Issue | Issue/Mod Description and fix |
---|---|---|
1 | Gate | in case you hear the gate signal - attack clicks - you can try to connect a 100nF polar cap** between GND and Trigger. Measure with an scope to find the best value - maybe you need a bigger value 220-470nf |

Sonicpotions CPU: (deprecated ) pls. use the Pixie CPU
Julian from Sonic Potions developed a CPU for the RE303, this CPU is also an replacement for TB-303

Forum about the CPU: http://23.235.199.139/~re303c5/forum/forum/7-re-303-cpu/
different cases are on the market:
Alu case in black, silver, white, gold..

Available in my shop: (shipping starts end of June 2020)
https://www.diysynth.de/pcbs-panels/re-303-pot-adapter.html
no wobbling potentiometers anymore !!!
you also need for the Midi Jacks an adapter.
BOM:
you need one of this Stereo Pot: (VR4 in the 303)
VR4 B50K Stereo !! (linear stereo)
VR2, VR7 = 50KB (lin)
VR3, VR5 =50KA (log)
VR6 = 1MA (log)
in total 6 potentiometers
https://www.thonk.co.uk/shop/alpha-9mm-pots-vertical-t18/
and you need:
pinstripes as shown above in my pictures.
2x 3.5mm (1/8inch) stereo jacks Lumberg KLB-4 which is available worldwide in hundreds of shops - its a quality part.
2x Adapter for the Midi holes to use the 3.5mm jacks - ONLY if you use the RE-303 Aluminum case - this are included with the PCB order in my shop !
2x 3.5mm (1/8 inch) plug to MIDI Cable - thonk or make your own.. https://www.thonk.co.uk/shop/alm-midi-trs-cable/ or DIY: NYS322 + 172-7435-E (mouser)
update 01/2020: ground the MIDI IN port too, that's needed because the acrylic's adapter to the stereo 3.5mm jacks are isolated
in case you use silver knobs: they are metalized and make grounding issues, you have to remove from the bottom the paint with a cutter knife.(easy)
the blue cable connects ground from MIDI out to the MIDI IN jack.
You will need 5x 1.2V AA batteries, get the ones from IKEA, they're from the same factory as the Eneloop ones but for a fraction of the cost.
Unless you can find a 5x AA battery tray best bet is to 3d print your own.
Then follow the official guide for installing the battery tray.
It is important to fit a 10 Ohm resistor as in this photo.
assembled versions are here:
Switching+DIN+Sync+Jack+Assembly+&+Installation.pdf
or create your own by 3D print it (SLA)
Switching DIN Sync Jack - housing.stl
Switching DIN Sync Jack - actuator.stl
- Switch: Alps Alpine SPVQ910205
- DIN 5 Jack: Multicomp PSG03463
the underlined lines are the value which I installed, you should use milled ic pins to make testing and replacement to your favorite sound easier
