Wireless glue gun?

Question

Had a quick thought. If you abandon the retractable stand idea and instead create a wireless charging base for the glue gun. A wireless glue gun would be really handy to have, in my opinion.

Anyway just a thought.

Clayton, This could be quite doable. I worked on some hand-held laser products where we would use a lithium-ion battery (2.1Ah @ 3.6V). We could pulse the lasers with approximately 100A peaks of current. We would PWM the laser (~50% at 20-30KHz) to create high energy bursts which would average out to about 50-60A for pulses of about 500-750mS with a pulse repetition rate of 2-3 pulses per second (allowing the battery and electronics to cool a bit). Worst case, this works out to about 30W, which is almost in the middle of the range for common glue guns (10 to 100W). A 2.1Ah @ 3.6V works out to about 7.5Wh, so at 30W watt rate you could get about 1/4 hour of on-time. Not great, but doable. Some cautions here, drawing this amount of current is possible, but you really have to watch the battery temperature. Our products would monitor battery temperature and limit pulsing to keep the battery in a safe range of operation. Play carefully! Gene
