This isn't something new. For a while I was planing to make third-hand, so I came up with this... You can say that is a multifunctional third-hand.
p.s.: I'm very sorry if some words are misspelled, english is my second language.
Step 1: 5V Regulator
I made 5 volt regulator with 7805 regulator and put it all together on a small circuit board. I was thinking it will be a good ideal to make it portable, so I made a switch to chose between battery or power supply.
Step 2: Housing Aka. Weight for a Hand
I made housing fro plastic an put some metal bits inside to make it heavy (I glue them together with super glue).
Step 3: Making a Hand
For I hand I use a body from I old microphone. Thought I pul 3 wires (Ground, 5V - from regulator and voltage from input).
And I put everything together.
Step 4: Making a Handle
With some plastic I made a handle so that I can "connect" different things on the top of the hand. Then I use some rubber and straps to mount the handle to the hand.
Step 5: Making Things for the Handle
For example I made motor (I will put some fans on It and use it for hot days :) ). In the future I'm planing to make fan to suck smoke from my soderiron and some bright LEDs to serve me as a nightstand light.
Step 6: More Things for Handle
- fan for sucking smoke from the soldering
