https://stream.echo6.co/videos/watch/4ceacb78-a833-463e-bb09-72eaa91a443e I love this unit. It's very clearly a low volume hand-made electronic product for a very niche market. It shows the quality results that can be achieved when somebody inventive uses a 3D printer. The circuitry also has a very distinct hand-rolled feel to it. I'm not going to go too deep into it, because it would be unethical to reverse engineer such a specialist product. And a huge amount of the work is done in the software locked in the microcontrollers anyway. Subsequent to the video I stripped the battery holders that had been damaged, neutralised the alkali damage with vinegar, rinsed them off with isopropanol, cleaned the contacts and then reassembled with fresh batteries and a note to the owner to remove batteries when in storage and use a complete fresh set for all major events to ensure reliability.
