405nm vs 445nm comparison

I’ve been a bit disappointed by the 445 nm diode so far. It’s not really burning as well as the 405nm diode. So I decided to put down some estimates to see what is happening. I was unable to focus … Continue reading

445nm 1 Watt monster diode

The 445nm diode came in and I’ve hooked it up to the CNC. This diode is a multi-mode laser diode. This means that the dot will not be nice and round as with the 405nm diode, but it has some … Continue reading

Stanham driver

To run a CNC laser you’ll need a laser diode driver (current source) that can be modulated. I wanted a driver that can be modulated with an analog voltage as well in case I want to give EMC control over … Continue reading

Laser530 paper stencil cutting

I finally received the BDR-S06J sleds and extracted the diodes from them. These diodes emit light at a wavelength of 405nm and go up to at least 500mA, where they put out about 600mWatts of power! That’s not bad. To … Continue reading

Seed studio PCBs arrived

Well that took a while. But the PCBs made by Seeed studios arrived today. I didn’t get a chance to populate them yet. Maybe I’ll get a chance to work on that tomorrow.

LPC-815 Diodes

The LPC-815 sleds and goggles arrived today. This guy made a great video showing you how to extract the diodes without harming them. Note that these are LOC (long open can) style diodes. That means the internals are not protected! … Continue reading
