I'm now working in a prototype of a switching driver, boost only and blu-ray only (because it needs 2.6V input to operate), which can boost a single Li-ion to about 7V @ 400mA, or to 5V @500mA, and it's capable of doing up to 12V but with less current. it'll be finished this summer, when I get...

I will take one for 6€ shipped, and once received i'll give you reputation and positive feedback so you can be more trusted here and sell more PHR's. What do you say? I've already had 5 transactions with members of this forums (rkcstr, hitechdealz, daguin and charlie bruce x2) and I had like 6...

Sometimes the bigger doesn't mean the better. With computer case fans you are going to deal with brushless motors, which are controlled by electronics that can't operate at low voltages, so you'll have a limited speed range. They also won't go very fast, only about 3500rpm max. And they are not...

Would you trade for laser diode drivers?

Big forums, BIGGER ONES end switching to a fully customised PHPBB system. It always happens...

Okay, then i'll use 3mm acrylic. It's rigid. I prefer plastic mirror because it can be drilled and it's light. my motors are 7mm coreless motors. Or i could buy styrene mirror and stick it to 1.6mm thick FR4, from PCB cutting scrap. That IS really rigid and stable.

Same here, bought two already

Thanks!!! Solved

"I"'ve found this great deal on first surface mirrors: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&Item=390052802400&Category=26258&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2 But the porblem is that they only send directly to the UK. I'm in spain so I can't buy this directly, and that's why...

I want the link for that flashlight, I just can't find it. And also for the heatsink.

Links!!!!

I think I had 6 rep points...

It's big. Very Big.

I bought 5 of them from daguin and they withstand 50mA perfectly. It's color is an orangeish-red

nah, no more than 2 at this moment. Better in heatsink. It's just to have some spare diodes to use as victims. If I don't blow any of them I won't probably need more PHR's for a while. Okay, I buy one right now!

Reserve me another diode or two. Gonna buy them... soon (probably by the end of next week) PS: this monday my exams end, and i have nearly all required parts for my driver... I hope I can get the high capacity ceramic capacitors soon, and build the first prototype It will finally be capable of...

I use 60/40 rosin core solder, and an adjustable temperature soldering station. Nothing resists to it. The sponge pad of the soldering station is used to remove residual flux after every solder, so the tip doesn't coat with burnt flux, which is like a black coating where solder doesn't stick...

link not working :(

Okay, no problem :) It's nothing innovative, as now electronics tend to run at lower voltages (3.3V instead of 5V) and this devices are prepaired to run at those voltages. Oh, and you'll see two innovative designs from me this summer, that now are at "simulation stage" with awesome results...
