Battery Charging Board
- Made this to charge multiple LED hula hoops off one USB. Charge rate is slow (100 mA per output) so usb load is also relatively low.
- Uses Freescale MC34671.
- Five (5) outputs.
- USB Micro power in.
- 2.5mm mono RCA socket for each output. I use a double ended 2.5mm cable and a 2.5mm socket on my hoops.
- 3 Status LEDs per output. PWR, FAST, CHRG. They are labeled for 1kOhm but probably use 10k on PWR and FAST to make them dimmer.
- Resistor labeled on board is for 100 ma charge rate.
- This has been assembled and is functional.

This is a simple traffic light bord based on a ATTINY85, 3 resisors and 3 leds (Red, Yellow, Green). The ATTINY is pre-programmed. Used as a soldering project
