Musings and comments about our common interest
First finished prototype of AAA classic charger. Back and front pictures of the part. The mid battery is a tight fit since it has compression on both sides. We have not received yet the adhesive flexible circuit that will make the contacts, so we have substituted it for adhesive copper foil. There will only be electrical contact in the angled parts - the other contact will be masked in the flex circuit. I expect to receive in the next 15 days. I am optimistic about the piece. It will be a nice companion for all classic users. If you use rechargeables AAA batteries you will be able to recharge them outside your calculator!
