Hi, im 35 and am (at the time of writing this) a 3rd year student at my local JC working towards an AS in Industrial Electronics. Ive always wanted to make toys or electronic gadgetry. My time at college motivated me to pursue buildable ideas I would have never pursued before. A whole new world for me.

    Thanks again Allen Pan for this amazing project. It was a real journey for me figuring it all out (read comments below for dramatic effect). I was able to pick up a pipe wrench with no ease of pulling it off. Totally awesome!

    You need more voltage. Try using the 4x 12v lead acid from the instructable or 4x 11.1v lipos.

    Made the same mistake myself. The primary is thick and light producing only about an ohm of resistance which is way to much current draw, dont use it. Just very carefully remove the varnish from the ends of the thin secondary coil wire. Youll be able to get an ohmic reading and solder to them then. High heat can cause the thin wire to snap off, so be carefull about doing that as well. Hope this helped.

    I was doing it all wrong. When prototyping, it would be wise to set your meter on continuity and connect it to the load side of your relay before adding the 44v load on. Then grab the handle, if your meter starts to beep scan your thumbprint until it stops beeping. If it stops your in business. Ive gotta re-center the handle and then imma finish this bad boy.

    I tried the example code with GT511C3 libraries again and was able to enroll and verify my thumbprints. Also the mjolnirb.fzz code was verified and loaded into the Arduino mini pro. However digital pin 10 isn't staying on HIGH when I grab the handle and scan my thumb. I've tried many line changes and at one point was able to get the relay to stay on but wasn't able to turn it off. I'm so close to getting this made. Can someone please help!!!!

    Tried the code again today and again the FPS zip library isn't being added to the Arduino list. I keep getting a "no valid library exists" error. Not finding much help online either. I tried to get the library from another source and was able to find one the Arduino would add, however when I tried to verify the code I got an #include "application.h" error. How do I add the FPS library if its not recognizing it as valid? Please someone respond.

    Why does the conductak image show 9 wires connected to the arduino and the fritzing shows 8? The gnd wiring for the relay, fps and arduino look like they all cennect to the same arduino gnd pin in the fritz diagram as well. On a side note lipos really made it roomy. And im nixing the touch sensor power system, i used insulating varnish on the pipe opening and around the fps along with electrical tape for good measure. Crossing my fingers i get the wiring right.

    How can i get the LCD display to show the the distances more clearer? Mine seems to be pretty dark even with the 10k trim pot adjusted the best it can be.
