Re: PCB designer? Weight issues.
toggle quoted message. . .
Thank you for the offer. It sounds like this board is being designed, so that should be taken care of.
To answer your questions though, I'd want anything on the thinnest PCB board readily available for weight savings, though Express PCB looks pretty slick.
I'm going to try out this solar upconverter/charge controller - https://www.tindie.com/
I'd be happy to hear any thoughts on whether you think this is a good idea or if there's anything I'm overlooking. I mostly need to ensure that there's enough juice between the smaller solar cells and the supercap to get through each transmission.
I'm at 5.8 grams for my 9 solar cells, so going to 2 cells should save around 3.5 grams. The charge controller is only .7 grams (around .4 grams if I order the thinner board from OSH Park and assemble it myself), so that's a savings of around 3 grams.
If my first flights work, I might try designing and fabricating my own custom payload boards - one tiny board to handle everything would be VERY small and MUCH easier to put together on a payload - and more reliable too without all of the wiring. This is what most of the very successful (global circumnavigation is a good measure) floating balloons go with. Some are as low as 6 grams (the weight of one US quarter) for the entire payload!
