Hello everybody! I have been develping an assisting device for the blind. The thing is, thanks to tiny AD ICs, I managed to make the power supply quite tiny, but now I have to think about a power connector to connect the devices' battery to the charger. I looked for half a day, but I couldn't find anything smaller, than our dear old-fashioned power jacks. Could perhaps someone advise me, whether some smaller and more convenient connector exists? some magnetic one wold be the best, something similar to magsafe, since it would be the easiest for blind people to connect. Please help!!
