Hey,
These are two builds that I made early on in my testing of the Open Boost Driver project. I built them to test how well the boost would hold up in different scenarios, with different currents set, and various degrees of heatsinking.
These were really "test builds", and they aren't perfect builds. I hadn't planned to sell them. But they may interest the right buyer, and I'm pricing them low at $75 each plus shipping, and also plus a $25 donation to Rob (pheonix77 - see this thread). I wouldn't ever want these considered "RHD builds", especially if you sell them on down the line. These were test builds. Hence them being priced so low. They're still cool, but you need to be mindful of their faults, which I'll lay out.
Here are the limitations:
- They will only fit very short 14500 cells. Protected cells will not work, and even slightly long unprotected cells won't. AW IMR 14500s will, and it's still tight.
- They work great on a full cell charge, but as the battery's voltage drops, it becomes too much for the drivers at the current they were set for (which was too high - 1.4A if memory serves). As a result, the builds pulse.
- On a full battery charge, I don't run into the pulsing, even after 2 minutes of use. But as the battery's charge drops, you'll find that the driver starts to pulse sooner and sooner into your usage (because the driver is having to draw more current from the cell, and do more work to boost the voltage).
The Black Build puts out 1300mW+, and the Silver Build puts out 1400mW+, both tested on an Ophir. Both use H-series diodes, and come with glass 3-element lenses.
You MUST NOT be a resident of Canada
You MUST own laser protection goggles appropriate for this wavelength, and
You MUST be over 20 years of age, and
You MUST be familiar and experienced with the appropriate safety precautions to take with lasers of this power.
