Yes. If it's working for you, you're fine. Your rubber shim is doing precisely the same thing, keeping the lens still/stable. Just make sure the rubber shim doesn't dry up or flake off small pieces over time as you adjust it from time to time. So FYI, here are a couple pics showing teflon...

Survival Laser sells springs as well as other places. You can use springs that go inside the laser diode's holder/cavity like this or ones that fit around the threaded lens holder like this (they also sell a 5-pack). I also use teflon tape (find at any hardware/plumber store) which also...

You are right, it is a schottky diode. I thought I had screened out the low Vf parts but missed this one. Thanks.

If I go down to around 50V, they're about half as much. And I'll probably get 10 for the price break (instead of just 8) so I thought I'd save around $10 too by getting the lower voltage versions.

Are you talking about something that looks like this? Those are available lots of places like here. It may have simply unscrewed all the way. It'll look like a flashlight until you get it in the position that focuses its.

You'll be duly impressed. Play safe.

Wait! 30W laser pointer for $367.16. Reduced from $3,671.60. Buy Now!

I found the DSE160 comes in a TO-247AD package. And the board is designed for a TO-220AC package. So did you mean "DSEI60 ... have 430 mil pin spacing where this board is designed for 200"? EDIT: NEW QUESTION The 20ETS08 diodes on the Survival Diode Test Load can withstand a VRRM of...

Yes, I know this can be a touchy subject. I do appreciate everyone's input. This is the first decision kids on both sides are facing for our parents (my dad remarried some 30+ years ago). He was at the hospital that performed his surgery for ~ 1 month. It took him 3 weeks to wake up and...

Thanks. I floated the idea of a broker to her/him. Waiting on a response. My dad is in the hospital right now. He's 80 and suffered a subdural hematoma (bleeding between the brain and skull). Wouldn't wake up for 3+ weeks so all his muscles have atrophied. We're coming up on 6+ weeks now...

Can you tell us what the diode part number is on the ones that work?

:bumpit: Is this allowed to get Edits to an existing post (#13) to cause the thread to reappear with added info?

OP's schematic in the above link (and the first one) doesn't show up in my browser for some reason ... :thinking: Agree with paul1598419's comment, configure as a constant current source instead of a voltage source. And if this part works like the LM317 configured as a constant current...

Great ideas and fast replies, thanks everyone. I've bought stuff from Rick before too but through eBay. Taylor was getting his hosts, heatsinks, and some other stuff from Rick I believe. In fact, as part of these latest transactions, I sent Taylor two of Rick's hosts and 1 or 2 heatsinks, I...

TaterMay has three lasers of mine that I purchased in Nov 2015. I created a thread here. Taylor became severely ill ~Jan/Feb and it took me until now to make contact with his wife, Anne, who finally located them and sent me pictures to prove they still had them. I managed to get some of my...

She says she is talking with him but he gets stressed about it which triggers the problem which hospitalized him in the first place thus tries to minimize bringing it up. As others here have posted, he must have a few of these problems brewing. She did finally ping me today about trying again...

You're pretty spot on. She got involved because he fell ill. She doesn't know a lot about these and had to find them. I sent her pictures to help. She contacted me using his email and phone so I wasn't really sure if it was still part of an elaborate scam. I asked for info to contact her...

PayPal ruled in my favor on three disputes. So that's ~$700 recovered but they still have a fully built laser with a custom Eghemus host and a Kryton host that I paid for. They are worth another $400-$500 I think. But I have not been able to get her to send them back. His wife texts me but...

Nice build. Have two questions. What's an AWS battery (couldn't find it on Google)? I'm not a big fan of the cone heads. Can you post a picture with it off? I have a few FA that may fit or maybe I could get one made. How wide is the host?
