Ok been searching for a while in the forums, no answer. Why is my test load giving me stange readings? Have I somehow messed my driver up? I have this driver: Variable Current Step-up (Boost) Laser Driver 405nm | eBay and it will either run from a 18650 or 3 aaas in series (calibrated with...

OK i have a small problem, just received this through the post: 405nm 300mW Blue-ray Laser Diode 6x Diode Sled | eBay After setting the driver 2pcs adjustable current laser diode driver 80-500mA w/TTL | eBay to ~250mA and connecting all the wires together I switch on my laser, and for the 30...

Ok so I am trying to design a circuit that controls an LED, and I need a way to disable the circuit if a voltage spike happens. The problem is I cant find an MCB that goes down to 0.1amps lol, the LED needs to remain active until the voltage running to it spikes by say 10%. Anyone have any...

As the title really, if some interest was generated I bet we could get a stupidly good deal on a big ol box of decent li-ions for maybe the same price as cheaper cells if bought individually. Was thinking some high quality sony, samsung, sanyo or similar. Pipe up if u r interested, and dont...

OK, so I have a battery question about Li-ions. I have a battery pack with a charger, from a makita 10.8v (this one Makita LCT204W 10.8v Cordless 2 Piece Drill Driver + Impact Driver Kit + 2 Lithium Battery 1.3ah : Tooled-Up.com). The batteries in the unit are dead; they are SE US18650VT (second...

OK so after the delights of a PHR-803t build, which was deliberately oversimplified (i'm a noob lol), but turned out well and taught me a bit. I.E. heat produces artifacts on the diode..... :beer: I am now going for a more complex BDR-S06J build (gonna keep it <500mw I think, but with a three...

OK so after ordering a load of 650nm diodes from ebay (china...), i decided to bite the bullet and just go for a setup from the UK based sellers: - a 100mW 405nm thingy (PHR-803T Sled Containing 100mW Blu-ray (405nm) Laser Diode - UK Stock Item | eBay), technical term sled ;), interestingly has...

Hey, I am new and almost clueless about lasers, good start? I have just got a batch of 650nm 5mW 5v 6mm diode/module thingies from ebay, 50pcs 5v 6mm 650nm dot Laser Dot Diode Module Head Red | eBay that I can use and abuse before I spend the same amount on a single diode. If I am right, I need...

Hello all! My name is Adam and I live in sunny England (sorry its July and the weather is shite...). I am interested in high power lasers, in fact anything with the potential for a little destruction :drool:. I am a novice with laser tech, and slightly above novice with my electrical skills, so...
