I usually don't have hundreds of dollars to spend on lasers but (because of that) I decided to get some kits as gifts for myself
first up: PHR @ 105mA in DildaV2 kit from Odicforce lasers. Nice little burner with unusual beam color that fits in pocket and still isn't too dangerous for eyes. Powered by 2x 3V CR2 batteries.
BTW this PHR looks a bit freaky to me - I think it has a bit higher wavelength, because it's a bit brighter to me than other PHR's I've seen yet.
This was my f1rst kit
But that was just some kind of heat-up, before some real build :eg: Now it's time for first 445nm
Originally, I was going to use microboost but I had some problems with it. But then I saw this thread:
and I remembered that I've got one of these drivers, so I quickly hooked it up on test load and discovered another problem. The driver would only go up to 450mA
Now it's running at 450mA, doing about 300mW. I ordered another NJG-18 driver from DX (and I hope it will go up to 1A)
I also put a 100nF capacitor in paralell to diode to prevent short spikes.
these were still pretty cheap builds:
PHR: $15 shipped (modwerx)
DildaV2 kit: about $22 shipped (odicforce)
CR2's + charger: $9 shipped (o-like)
Host: Guidesman $15 shipped (from mohrenberg) (what a deal! )
Diode: $56 shipped (from DTR)
445nm lens: $11 (from jayrob)
NJG-18 driver: $4.26 (DX)
Total: $86.26 (I don't count the non-working microboost)
Special :thanks: to jay, moh & DTR for the parts!
