Thanks that thread is very useful and the use of the zener is very clever.

Thank you. One question, what is the zener for? Why would you want the FB connected to the V+ like that?

It takes me a while to make boards though. I'm just looking to see if anyone who has experience with this kind of thing can tell me if everything checks out before I do make some pcbs.

So it's time for me to try to build a smps driver. I've been working on a design with the tps63020 and lt6106, but I'm still not sure if I've got the math and schematic right. So if you look at my schematic, from looking at the data sheets for the two ICs, I think the equation would be...

I recently bought this http://http://cgi.ebay.com/new-150mW-650nm-Burning-Red-Laser-Diode-profession-/270785571982?pt=LH_DefaultDomain_0&hash=item3f0c13ec8e actually I bought 2. For 4 bucks each I thought might as well. Well I've never used a diode like this and looking on sam's laser faq it...

how about ir1,2,3,or 4?

I recently accidentally smashed my laser goggles :cryyy: Unfortunately until I get a new pair I can't test the 1w 808nm laser I'm working on. However, I don't have a lot of money to spend on goggles at the moment and I'm unable to find any for <20 usd. I have found welding goggles that claim to...

Yes, I'm aware of that so I always make sure I wear laser glasses to protect from reflections. I used to use 100mw greens without goggles and the brightness of looking at the beam on a wall would almost be too bright to look at so I'm sure that 1 watt or more reflected would be very bad for your...

Thanks, I'll stick with 9mm for now. I already have a nice module, costed about 6 bucks including shipping on ebay and came with a nice glass lens and spring. Press fit is great because you can press it all the way in with your fingers. And yes, I am looking for a burner and I want to build a...

So I'm interested in building something like this www.rayfoss.com I'm wondering whether that would contain an overpowered 9mm or a c-mount. Any guesses? By the way, anyone know a good sight(s) to buy high power 9mm, c-mount, or bar diodes?

Thanks, I'll probably buy some and run them at 2 amps to start. Yeah, I added an led indicator to the driver I made and I have glasses rated for 808nm.

I've bought 1 watt diodes off ebay but I'm looking for a little bit more power. I found these Amazon.com: HIGH POWER Burning Cutting Laser Diode 2w 9mm 808nm: Electronics but I'm a little suspect that they really can put out 2 watts. Anyone know where I can get some legit higher power ir diodes...
