Just finished my first puck, which is my first box mod. This thing is great. I drip into a SmokeTech 2 ohm atomizer. Made just a few changes though. I put a coaial power plug on the top edge, along with the atomizer connector, pushbutton switch and 2 led's. The sides are clean. One AAA box houses the 4 batteries, 1000 mah, and the other AAA box holds the goodies and the battery charger circuitry. One led shows when the master switch has 'armed' the unit, the other shows when I press the button for a puff. Was thinking about a third led for a low battery indicator, but there's just no more room on the top edge. The total cost including batteries, using all Radio Shack parts was 28 bucks...not bad at all.
I'm so impressed with my first box, I'm beginning work on my superpuck!
Mirror finish aluminum housing with black trim
6 AA 2500 mah NiMH batteries
0-6 volt variable voltage, 6 amps max
LED's for Activated and Low Battery
3 digit voltmeter display
10-turn, knob adjustable voltage
Tactile feel, silicone actuator switch
I'd like a slightly higher voltage, but there's just no more room for another battery. Must maintain 1.2 volts between batteries and output. If I've left anything out, let me know. Maybe a feeder mod in the future, but again, with this much power and frills, it just can't fit in my hand.
