I hate it when that happens!
**** Or anywhere else either! ***** Awesome hack, not too safe, no backup rope. I wouldn't do it without a belay. Impressive!
MIG and/or TIG can be a very awesome welding system. MIG is a little cheaper welder, and thus more popular, there are things you can do with TIG that won't work with MIG. First time I tried a MIG, I sat down and signed my name in a piece of steel, I bought the used rig right then and there, probably my most expensive impulse buy ever. Never regretted it.
I've been involved in some rockclimbing, and also adapting rockclimbing equipment to building inspection/safety. Two things make me nervous about this. First, in ladder safety they insist three points of contact at all times. Only move one point of contact (hand/foot). In this case we're moving two attachment points. It would be safer if the hand and foot were independently switched. That way only move the hand, then switch the left foot and move it, then switch the right foot and move it, etc. Second, what about battery/electronics failure? Pretty much catastrophic. We do something similar in climbing with ropes and a gizmo called a jumar. It only takes two jumars to climb a rope, but there is always a third that simply attaches to the harness. I used such a rig just yesterday to climb a tree - the third attachment point was needed just to have a rest every once in a while. Many ladder systems on tall objects like power plant stacks have a rail in the middle where a simple ratcheting safety cam attaches. You can't fall even if you let go of both hands and your feet slip out, the cam on the third rail stops your fall. If one of the steel rails you are climbing is such a rail, (or both of them) then a mechanical safety could stop a catastrophic power failure. Nice hack guys!

Hello!I building a battery with these cells Samsung ICR18650-26F 2600mAh (Pink) http://lygte-info.dk/review/batteries2012/Samsung%...With a pack with "7S4P" I get a nominal voltage 3.7V x 7=25.9V and nominal current 2.6A x 4 = 10.4 A.I´m thinking to use 3 Power Supply in serie with 12V each, with total 36V, to charge this pack I will need 4.2V x 7 = 29.4V, I will use a Buck Converter Step-down Power Supply Module, like this one http://www.ebay.co.uk/itm/DC-DC-CC-CV-Buck-Convert... to give only 29.4V.I read that for give a bigger live to the pack I should charge only 80%.How I can do to control the max. current, for example 3A?You have any sugestion how I could stop the charge when I have 80% already charged, I can use a current sensor to stop the charge! what you think about it?In this case the charge should stop with how much current? I don´t see how I can calculate the current value to stop charging. Any sugestion?thanks a lot.
