Hey guys/gals I'm building a custom minty with a custom NIMH charger all rolled into one package, home built so it wont be so tiny
and I was looking at voltages. I'm using a home made solar panel to charge the battery and power the minty/charger during the day. From what I understand its not safe to run the LT1302-5's input at or near 5v, but from the datasheet if you add a 10ohm resister before the caps at the Vin it will work. Has anyone tried this? I'm getting the last of my parts in next week and was trying to figure out what size solar panel ill be making and a few small pieces, I would rather not have to add extra diodes to drop voltage in between the battery and the LT. I'm an electronics student at the local ITT Tech so I have access to silly scopes and power supplies during the week. But since LT1302-5's are hard to come by (as in buy 100 from LT or pay $8 each and $20 for under $100 orders) I figured I would ask for input before I burn one trying....
I'm using a low power version of the 555 charge controller from Michael Davis. http://www.mdpub.com/555Controller/index.html
I'd like to thank Linear Technology for the free samples now, just encase I kill them before I get done
also Cadsoft EAGLE FTW
