The red diode (LPC-815) is all ready to go, but unfortunately, I don't have a working driver. I thought that these would work, but on second look (i.e. after I had already bought them), they use TTL modulation. Normally, this wouldn't be an issue (I would just use it without the modulation), but I'm pretty sure the opamp on there requires 5V input, so an 18650 won't work in this case. I'll have to buy another driver before I can get this laser working.
Okay, after several weeks of procrastination and waiting, I've finally built the last laser in this set. After discovering that the driver that I originally purchased wouldn't be useful, I ordered a FlexDrive and set the current for 420mA.
Unfortunately, after installing the drive, that's as far as I got. The diode refused to power up. So, I had to order another (and wait until I went home, where I had left all my diode extraction and press tools). But, things worked out nicely in the end.
Instead of soldering little wires between the diode and the driver, I decided to try soldering the pins directly. Because the diode and driver is encased firmly, I don't need to worry about the solder joints breaking. Can you spot the ridiculously stupid error in this pic?
Yeah, that's right; I had the pins swapped, so I had to resolder it. Luckily, the diode wasn't damaged.
