Boys and girls.....
Who is brave enough to post a good driver schematic.
built around opamps and fet's with analog and TTL input.
With a slow start and TEC function optional.
Let me check the temp in hell... still hot. So NOBODY
not because of some guys here who would make them for their own use but because of many bad guys watching PL who will make money with
with other people work.
It's all here and very old already: http://www.photonlexicon.com/forums/...and-TEC-Driver
Shouldn't be a big deal to adapt this to the current needs. In fact a successor of this old one was made for a groupbuy at LF some years ago and is field proven (over 200 units made in the groupbuy at this time): http://www.laserfreak.net/forum/view...49839&start=75
Any other highside driver uses the same principle circuit anyways, including the badpip driver and many others. The use of the old schematic and layout is free to use for personal use, so get your soldering iron out!

Not everyone can build drivers themselves.
The more electrical schematics are posted .. and the more people who will make them...
Then they become cheaper ....
and the real bad guys do their thing anyway.
let's help each other hre on PL, our hobby is expensive enough.
Yep, another high side driver very loosely based on Andy's design, but with beam supression, startup delay.. Production takes about a month from when I order, which should be soon at this rate.. I just want to run over some more tests before pulling the trigger on a run of 100 assembled boards..
