Hey backers,
A month in electronics quickly goes by…
You design a new version of a PCB, send them to the manufacturer, goes back & forth with design modifications.
Once agreed, they start the job and finish it within a week (which is super fast, normally +2 weeks).
You then assemble manually the PCBs, instead of going with a PCB assembly factory, since it’s faster and cheaper for prototyping. That takes usually a week if you don’t have any problems.
We’re at the end of this cycle and got great results. Probably going to be in pre-production in a few weeks. Sylvain tried it and it worked almost perfectly (9 out of 10), there were very few cutouts. He then recharged it and… it stopped working as it should :/
That’s the price to pay when you assemble the PCBs yourself vs automation, you are more prone to slight imperfections in the assembly process.
We think it’s because of the bandpass filter chip that was not correctly soldered. Only a slight misalignment of 10 microns is needed to malfunction. 10 microns is extremely small, a red blood cell is 5 micron and a single hair is 75 microns thick.
We will have to do a new PCB manual assembly again. We have the most recent stencils so it should be more reliable. He shall recreate the great results he had, but let’s not get ahead of ourselves 🙂
We are officially requesting beta testers. It will be in Montreal and the date has to be fixed, but that would be in the middle or end of April.
