Alan's Variable Voltage Phaser

Well, not exactly, but I don't know how to describe it exactly. Ergonomically-designed, how's that? The Dollar Store loves me. When we go shopping I always look for something moddable.

Last night we went to "the big city" for a meeting. Of course, that means a stop at Dollar Tree ... I looked in the hardware dept and the cutest little personal fan caught my eye. It was love at first sight!

I originally planned to make it into a bottom feed 3.7v, but discovered that I didn't have any bottles that would fit in place of a 14500. Guess I need to make another Madvapes order! Anyway, since that was out, I decided to make it into a VV, using the "poorvari" LM350T circuit. Here is the result.


It's a variable voltage 801 mod. It's voltage range is 2.9v to 6.9v. It is adjusted with a multi-tun screwdriver-type trimmer pot accessible from the side of the unit.


I used a concave 6amp horn button I got from Goodprophets.com


Here is a view of the 801 connector. Since it is transparent, I took special care to keep the components installed as neatly as possible. Also, since you can see thru it, I did not hot glue anything like I usually do.


The pic doesn't do it justice, but the entire unit glows when you're hitting it, thanks to an internal hi-output white LED


Cost to build:
Personal fan, $1 Dollar Tree
Horn Button, $1 Goodprophet
801 Connector, $1 Goodprophet
LM350T VV regulator, $1 Ebay
Resistors and LED, already had them in my parts bins, $0

Total cost: approx $4

Not bad for another good working (and cool looking) variable voltage mod.
