hi roboRad

how big would the charger be.:D lol.

I want to see the 6 foot Jd, when will it be completed?

Are you going to 3D print all the JD 6 foot tall pieces?

Sealed lead acid batteries for the win , 2-4 12v 35 ah batteries will keep it powered for hours. I recommend power sonic brand , fantastic quality to money.

Are you set on a certain way to construct him? I would say your quickest and most accurate option would be to 3D print just the edges of the model and then glue dowels as a temporary frame. Stretch fleece  cloth and hot glue will make a skin, then apply resin epoxy or polyesters when your happy with the outline of your shapes and when they harden you have a large, light and fairly hollow part. You can add fiberglass, Kevlar or other woven cloth to reinforce corners.

Sorry Josh, the comments at the beginning of this thread were referencing the Astro Boy project since I was originally going to Hack Astro. I then switched this Live Hack to the 6 foot JD project half way through Friday. The 6 foot JD is commissioned by EZ-Robot, I am contracting for them. It is built with foam pieces that will be sealed and painted after the dimensions are right. It will be run with a 5V 20A power supply.

Hey Nomad I just use a universal battery charger,does every type of battery,usually takes all afternoon to do them all but then I can go 3 or 4 days before recharge again.

Any new pictures of the Giant JD? Human sized robots are the future by the way
