Summary

For many small electronic projects, a 5 Volt (4.5) power source is required. Small microprocessors like ATtiny become very portable with this device. It is a simple rectangular block with a button cell shaped cavity and a small hole at the two ends. Two push pins take care of a proper connection and can be soldered to the curcuit. When the cells are inserted, the box deforms a little, taking care of stable clamping of the batteries.They print in a very short time and more of them can be printed in one run.
