My boards arrived today so I have assembled a few of these drivers. Unfortunately I am still waiting on the correct rated sense resistors as I only realised afterwards that I ordered 1/8W resistors and not 1/3W resistors. But tried it for a few seconds and was giving me a solid 0.88A set to low...

It's even worse in Australia. Shipping from Digikey is $30 and our Australian version is $13 for anything

Yeah thanks, might try that. I tried it like this because I honestly didn't know what to ask, I paid $125 last year but I know that the release of the radiant X4 means that it's not going to be worth nearly that much. But might put it up on eBay tonight

Saducees was selling one here. Don't know if viper bought it or not though

Yeah Aussie Laser Laws are another reason that I'm considering just selling them as JAD kits. If I did end up selling them as complete lasers, it would most definitely be only to people that I trusted. Thanks for your input

TO ADMINS: Sorry, clicked on the wrong sub-forum :oops:. Could someone please move this over to 445 lasers? :thanks: Hi Everyone, Just looking for some input on what you think people would be more interested in right now. Very soon I will the parts for 20 C6 M140 @ 1.2A lasers, except the...

Seriously, any offers considered. Also updated to include the diodes that I am selling too

Yeah Australia doesn't care about diodes or modules as long as its not in a handheld laser that you just need to add batteries to

Selling my 1W Laserbee I with Ellipsis firmware. Bought this from Trevor 1 year ago, but am now selling to upgrade to an ophir based LPM to measure the higher powered lasers I will soon be building. The difference between original Laserbee firmware and the Ellipsis firmware is explained well in...

I'll take 2 diodes at that price. 1 in module and one as bare diode. Both with lenses in holders. Added it to the drive document (pretty sure I did, never done it before though). Thanks for organising this

Re: OPEN SOURCE: New Boost Drive, 2.4A capable from one cell, tested and working I've got an order on too for 12 drivers worth of parts to give my toaster oven reflowing a go and test out how well I can make them. If all goes well I should be making a run of about 50-100 soon. I've also got...

Re: OPEN SOURCE: New Boost Drive, 2.4A capable from one cell, tested and working Looks like it'd be closer to $5 per driver than $10. Cost of components from digikey plus the FP6298 from aliexpress would come to $4.69 USD at the 50 unit price break. Plus whatever the cost of the PCB would be...

Thanks for the link. That thread was actually what stopped me buying the head immediately, where ultimatekaiser mentioned the coatings might be wrong. I've read through it a few times but just wanted to see if any other members had experience/knowledge of that specific head.

Just wondering if anybody knows much about this OPHIR head? The part number is 170298 and has on back 150W-A-.04-Y. Was told that it is for CO2 and YAG lasers. My main interest is if it could be used in a LPM for visible spectrum? And how much do you think it would be worth?

Yeah it is wirewound. I couldn't find the proper test load that I made so I just threw one together. But thanks for the warning anyway.

Looks like there was a short within the pill that caused the problems. But now I think that I have probably killed the driver. My test load shows .08A with 5 diodes, .47 A with 4 diodes and .36 A using an LED'd diode as a test. I have tried hooking it up to a diode, the first on LED'd in less...

I'm in the process of my first real laser build. I had hooked up my BlitzLinear driver across a test load, but measured no voltage across my 1 ohm resistor. I tested the voltage across the input of the driver and only saw .4 volts. The voltage at the output is around .2 volts. I know that the...

Re: Osram diodes 520/450 GB I'm in for 4x 515nm if someone drops out or if a lot 4 opens up

Re: 18650 Battery for $0.01 at TMart.com Just did it from AUS and it worked. AU$3.93 discounted to AU$0.01

Thanks for your comments guys. I'm glad you liked the beamshots, I'm actually really happy about the way that the second one turned out. Anyway, today I added the diode and heatsinking that I said I would and I have updated the OP with the new graph. I seemed to get a higher average value but...
