The ATX power supply can be found in many old desktop computers.  Mine came from an old PC that was running windows ME.  The ATX has 12Vdc, 5Vdc & 3.3Vdc terminals ready to go.  It also has built in overload protection, making it an ideal power supply for prototyping.

I decided to integrate a old multimeter I had laying around Into my power supply.  This will be handy when troubleshooting new circuits.  I was able to salvage the origal connector from the PCs motherboard.  To attach both the multimeter and the connector to my project enclosure, I used an old tip on my soldering iron and welded the plastics together.

To make the most of my power supply, I decided to add some AC voltage as well.  I included a 120V to 24V AC transformer and a 120V outlet connected through a dimmer switch, which gives me a range of about 80V-120V.  Finally, I squeezed in a couple of USB ports connected to the ATX 5Vdc terminals and a 12Vdc automotive power socket connected to the 12Vdc terminals of the ATX.

With this power supply voltage is adjustable from 0-23Vdc and amperage is adjustable from 0-3 amps.

With the ability to dial in voltage and make adjustments to amperage this power supply is a huge improvement over the ATX power supply, although both have their place in my workshop.

I came across the InMoov project while I was browsing Thingaverse for something to 3D print and knew immediately I would have to accept the challenge of building the hand.  If you have never heard of InMoov you can check it out Here on the InMoov Home Page. To get started, I decided to try the finger starter.  I figured if I could get the index finger to work then the hand should be doable.  I had the parts for the index finger and the finger sarter base printed and I set up an Arduino Uno with a servo.  I was able to thread fishing line through the finger and attach to the servo.  With a simple sketch uploaded to the Arduino, I had the index finger working with three types of control.

With the index finger a succes, it was time to move forward with the hand.  Since I have no 3D printer, I had to use a combination of 3Dhubs.com and the local library MakerSpace to get the parts printed.  I've found 3Dhubs to be a great resource for affordable printing services, with hubs in my local area and more than 10,000 hubs globally to choose from.  However, I had the parts for the right hand printed for 5 cents a gram at the MakerSpace in my local library.  Keeping the parts organized is key here.

After hours of careful sanding and drilling, I had all the parts fitting together nicely and moving freely.  A little epoxy and 100lb fishing line and the hand was taking shape.  I don't have the forearm and servo bed printed yet, but can't wait to start animating the hand.
