Hi there
My first homemade flashlight. :twothumbs
This was a project just to gain some experience with leds. Before I never did anything with leds. Next summer I have a rc car project to build with leds in it so I don't want to start testing when I need to know how it works. I don't like to break expensive stuff because of not knowing what I'm doing.
So by the way I needed a bright flashlight that can light up a whole room for min. 1 hour in candle mode.
Parts I used:
15 Year old Ucar flashlight 0€
Old AMD Athlon CPU cooler 0€
LED Boost driver LED Senser V2 30€(The original setup had 3 drivers each with its own switch but that didn't worked because those ebay drivers flickered and didn't got more than 680mA)
3x CREE XP-G R5 on Star 19,50€
1x CREE LXP Optik 10° 2,49€
1x CREE LXP Optik 26° 2,49€
1x CREE LXP Optik 46° 2,49€
2x 4*AA Battery holder 3€ (I accidently destroyed 1 with my chair so I had to improvise :shakehead)
1x Mighty Mini Blower 15€ (When I saw it while I was looking for the battery holders I knew I have to buy it no matter what it costs (planed setup had an old Radeon 9600XT fan))
Some cables and stuff like that... 2€
Tools I used: (This should be an experiment so I didn't even looked at the lathe)
Knive
Pliers
Soldering iron
Hand saw
Electrical grindstone
Screwdriver
Beer
Cordless drill
The screw in the middle is battery + for the LEDs. The spring is 4xAA + for the fan. Yes I know those batterys should get empty before the other 4. But the fan only needs ~45-50mA so that doesn't matter. Also I put in those 4 slots the batterys in which have more charge than others. Those 2900 Ni-MH have +-200mAh when I take them out of the charger.
That copper plate on the back is battery - for LEDs and fan. The copper plate is cut of from the CPU cooler... :devil: ...I still have lots of them... :naughty:
You might say those edges from that copper plate look very sharp... ...I can tell you they are very sharp. I was just too lazy to get a file from the basement. :sick2:
There you can see the mighty mini blower. I love that fan. Such a nice piece of fan-technology... :naughty:
