Gadget Gangster Answered
Some time back you offered projects from a GadgetGangster.Com. That link is no longer valid so I'm wondering if you have any further details how I can get in touch with Nick McClink who was the owner and engineer behind their products.
In particular, I'm interested in the 4 Channel DMX Transceiver ( https://www.instructables.com/id/4-Channel-DMX-transceiver/ ).
If anyone has a photo of the back side of the PCB or a schematic of the design, I think I could recreate this project on my own. The Raspberry Pi code would of course also be very helpful.
Thank you in advance for any help you can provide.
