My two new red laser builds

[ReNNo]

This time I managed to make two red laser builds that are smaller than one I made before.

First build uses two 10440 batteries and LM1117 as driver and everything is assembled in pen host (from DX green lasers).
Current is about 390mA and stays stable.





My second build uses one 14500 battery and AMC7135 chip.
Yeah, these chips are very small and perfect for small builds.
With small magnet from sled that acts like heatsink AMC7135 stays just warm.
This build works stable at 333mA.





These builds are as the cheapest as they can be and price is at first place.

I hope this can help someone to make similar laser that is not expensive.

Nice builds man... Any burning power?

Nice builds man... Any burning power?

probably as the currents are at 390mA and 333mA

Nicely done! Looks good and not a budget breaker.

And I'm still unable to disassemble DX pens without hardly damaging them -.-

Nice work!
