hmn everyone seems to be recommending ltspice on the electrical engineers forum though there are mentions of more user friendly solutions. *shrug*
I’ll try it and see how far I can get.
Electrical engineers: what Spice program do you guys recommend that is easy to use for simulating analog circuits? (opamps, sallen-key filters) ?
Literally a disaster.
Wow. Never have I had second-hand embarrassment like this
Anon: if you can’t seem to quite follow: feel free to ask more questions even if they might sound stupid. A question answered is always better then leaving something unanswered resulting in confusion at a later time.
Every human being “can” be loaded with a small electric charge which is really really small. Maybe you remember the trick where you’d rub a balloon on your shirt and your hair would stick to it or when you once got a spark from touching something? This Static energy can be really small or fairly large.
Touching an object where it can discharge is called The ElectroStatic Discharge. Some electronic components can in fact fry or die from this discharge (some components being way more sensitive).
Once installed the laser is a lot less sensitive since I install a lasorb which protects it.
Here have an example of an unprotected laser diode dieing with just one small ESD pulse (which can be generated by humans easly)
You’ll see the laser suddenly is a lot less bright when the pulse gets fired and the laser diode goes LED (yes it turns into a very expensive LED which emits no more collimated light).
This can be a very expensive LED as some diodes cost 160$ A PIECE and in some projectors there can be about 5 or more of those (just for one color).
I should add that a way to avoid ESD is to ground yourself so you cannot discharge. Something like this will do: http://www.ebay.com/itm/W3LE-New-Anti-Static-ESD-Wrist-Strap-Discharge-Band-Grounding-silicone-bracelet-/310816568526?pt=LH_DefaultDomain_0&hash=item485e1c74ce
Do NOT wear latex gloves EVER while handling electronics or laser diodes (they generate static electricity (think back of the balloon)).
These schematics look interesting. http://www.pangolin.com/resguide03d.htm
Replacement LPC-826 open can laser diode recieved!
Now I can finally replace the one in my graphics projector.
(The LPC-826 is extremely ESD sensitive)
ESD from your hands/fingers can easly kill it.
Been practicing more and more analog circuit design.
(Still am) It’s going really well.
In a few days I might be making a fully analog laser color correction board.
Red laser diode went led. Order an new diode by express post and it should be here in 2 days.
Then the graphics projector is fixed!
I really hate mechanical probs especially when you want to make a comeback on youtube asap
