Hello all, I am an electrical engineer joined the forum today.
Here are some pix of what I do on a daily basin

I design and manufacture circuit boards for work, and do a little machining as well as automotive work for hobbies. My biggest laser/LED projects are:
An old helium neon laser with XY mirrors for light shows
A 6D maglite with a luminus devices SBT-90 LED soldered to a solid copper base, screwed to an aluminum cup to move heat into the body of the flashlight.
A 6D maglite with a CREE XHP-70 LED mounted the same way as above.
Both of those use real constant current drivers, the Luminus takes 9 amps so it uses 8 sub C drill batteries while the CREE takes 5 18650s
I'll upload some pics of those tonight.
I am excited to do some 18650 teardowns to help the other forum users identify batteries to avoid, also I am planning on starting to collect some rare wavelength lasers soon!
