Thanks for the answers :D One of my worries is the power output, even if i buy it there's no way to know if it's up to spec as I don't have a LPM. About the power supply it don't seem to be included, other sellers have it with a 5V supply but without the fan. The power supply seems to be very...

Hi everyone, today in ebay I found this, in the first and third pic it says that it is from MTO-Laser. I was wondering about the quality of the laser but I found nothing about MTO using the LPF searchbar. So I'm here asking if anyone owns a laser made by MTO or knows something about the...

I'll be sending the laser to DTR so he can check it but when it comes back I'll try this method, by ramping the voltage I hope to say goodbye to any nasty transient.

I don't belive beeing a student today is as hard as in 1982, instead of oatmeal I have tons of noodles :D I can't thank you enough for that help, it really made my day (or night considering it's around 00:40 here). Tomorrow after I check if the driver is still alive I'll PM you all the details.

I paid 118$ + shipping (don't remember exactly how much) for the whole pack. I aprecciate the intention :thanks: it's hard to find kind people in the internet, but since I'm in Chile the shipping (asuming the guy you know lives in Alaska) might be as costy as purchasing another diode from DTR...

Comparing the two approaches I think I'll start powering on/off before conecting, even if it gets some bounce it would still be in the 5V range keeping the input below the boost's output voltage. Tomorrow I'll desolder the diode and make a test load to check if the driver is still alive.

I thought about the connecting and power on/off order before making the tests, if I connect the driver to the PS with the voltage already in 5V it will still receive some spikes due to the connection bounce.

That's a fast reply :yh: I didn't touch the driver setting so it should be at 600mA (DTR's default for this pack). And the power supply is set at constant 5V.

Hi everyone, today I killed a BDR-209 and I'm not sure what actually killed it :yabbem:. I recently got it from DTR (the one with the copper module + driver + G2 lens), I was doing the first tests to see if it arrived ok, in the picture is the setup used. The procedure was the following...

Mainly because it's hard to suggest places to buy pieces when people don't know if the store ships to your country/city. When it comes to prices your country/city is important because you can save some buying from a local store to avoid the shipping expenses.

Hello and welcome to the forum! I'm new around here but i can answer a couple of your questions. First people usually introduce themselves in the Welcome forum and tell a little about why are them interested in the hobby. You already said that you wanted to make a 100mW green handheld so that...

Please forget my question about the safety goggles, i looked it up myself in the forum and it has been stated several times that cheap safety glasses from ebay shouldn't be trusted :tsk: I will play safe and buy an Eagle Pair from Survival Laser instead.

Thank you all for your answers. Everyone seems to agree that the 405nm diode is the best option so far. I have to wait till monday to make the order from my job so i'd love to hear more people agreeing with this. Also which safety goggles will be best for the the 900mW@405nm diode? i've seen...

For the moment i pretend to use G-code as i'm not familiar with other formats yet. The process i want to follow is in this post ( Making PCB's with a diodelaser ) so the black paint is mainly to coat the copper that i don't want to etch, and after etching the board the paint can be removed with...

Hello to everyone, i'm looking for advice concerning the selection of a diode. I want to make isolation routing for small PCBs primarily for prototypes. My plan is to paint the copper with black paint then burn some of the paint away with a laser to make the routes and pads and then etch the...
