O-Like laser drive PCBs

First 2 on the left(without a spring) are identical IR/Red drives(only different side) and the third one is a bluray(PHR type) driver.
With the one without a spring and 2AA/AAA rechargeables you can get about 120~160mA of current for your Red/IR. Depends on the state of those batts. With 5V of input voltage you can get the 22x dvd burner diode to its maximum optical power output! Quite good actually, I'm pleased to get 2 of these for only about $5!!! btw. This driver has a TTL input.
The other one, I would call it a PHR/spring driver, is a bit different story. 2AA rechargeable batteries simply aren't enough. Fresh ones may work well and probably be able to get you around 90mA for your violet diode. Remember bluray/HD diode unlike dvd red is kind of voltage hungry and needs around 4.5V. So the driver is actually boosting voltage from only 2.4V into like 4.4V. That's really great, but doesn't help it much anyway. xD You can still burn electrical tape slowly, but the dot is dim and the beam barely visible. Try replacing 2.4V with 5V let's say from a USB port. Suddently you'll get the driver's top at like *143mA(my sample).
The PHR drive costs 10$. And you'll get only one.
In the end, I would say, power both drivers with one 3.7V battery. Get a nice host and go burn your house down. LMAO



*I don't recommend this high current though, the laser module gets hot really fast, untouchable. I measured maximum current with my laser test load. You should do it too before hooking your expensive diode up with any driver! To set the driver for your diode, you can adjust output by turning a mini pot on the PCB with a little screwdriver.
