Step 35: Powering the Electronics

The entire thing needs to be powered from one plug, and all the electronics were on top of the sculpture in the crown. These things need powered:

The inspiration for routing power through the metal bars was from a suggestion by a fellow AiR, Paolo Salvagione. He suggested I explore converting the signal to 12v DC and run them up the metal support rails. I had to tap threads the threads in the top and bottom of two of the bars so I could use molex connectors to wire them to the power supply in the base, and connect them to an inverter in the crown.

For the power chain I used:

  • Generic 12v DC 60a 720w Power Supply (found on eBay)
  • 750w A/C Inverter w/2 outlets (found on Amazon)
  • 12-gauge insulated cable
  • Molex connectors

At first I was actually wary of pursuing this method because I couldn't help but to think that someone would get shocked when touching both the bars at the same time. It wasn't until I physically tested it and touched both bars at the same time that I confirmed for my brain that you won't get shocked, and the entire thing works flawlessly. The human body is an insulator and can't complete the circuit better than the metal bars can. Also, if you were to somehow short the circuit, the fuse on the power supply or the inverter would blow before shocking you.

<p>amazing, me and my friend are going to make it at our school</p>
<p>Amaizing project. </p>
<p>Whoa. Interesting bit about the sun-bleached ABS -- it's quite beautiful!</p>
<p>truly amazing process. </p>
<p>congrats Gabe! Looks so great man! Love the design &amp; process!</p>
so difficultT_T
this is so beautiful
<p>Very, very cool project! I really enjoyed reading your process in making this. </p>
