A treasure trove of maker goodness (Hording Trigger Warning)

Neither an isolation transformer nor a GFCI (GFI, RCD, etc.) will help if you get between Hot and Neutral.

The isolation transformer allows the circuit to float the potential of whatever your other hand happens to be sitting on when you touch the wrong thing inside of the chassis. No current (or very little) flows and you are safe.

A GFCI doesn’t float the circuit, but does detect that current on Hot and Neutral differ by more than the trip current, and then pop the internal breaker.

The mechanisms of operation are quite different, but the protection afforded by either solution is roughly equivalent.

Can we expect another visit this weekend? I’ve been twice and always find something interesting. Fred is responsive to emails if you have questions.

I have rented a box truck w/ a lift gate for this weekend. Primarily this is to get the 2 H.A.S.T. chambers for the Machine Shop and Science committees, but if anyone else needs help moving large items from MilTec to DMS this weekend we can try to fit those in. I will likely be making the trip(s) Saturday and/or Sunday afternoon.

@artg_dms perhaps this would be a good opportunity to get the cabinet of drawers over to the electronics room?

#85

And where is this supposed cabinet of drawers gonna go? We have too much stuff from MilTec as it is. If you find room great but don’t just dump it in the middle of the room. Pretty Please :wink:

Art would be better to answer, but the thought we had was that we could replace much of the existing parts storage with these cabinets. And we were talking about constructing a platform with castors for them to rest on so they could be moved about (less of an obstacle then the existing tower of parts).

#87

Awesome, BTW the tower of doom and the cart need to go. If the cabinet then fits great, all for it.

#88

Heading over this afternoon to check out scrap and such, should anyone wish to join me.

Any idea on what your schedule is? There arr 4 cabinets that go to DMS. They can be moved w/pu, but the box truck would probably make it a lot easier.

#90

Damn I’m in Oklahoma or I’d be there to help move Machine Shop’s and CA’s cabinet. Will you be doing it on Saturday or Sunday - may be able to cut trip short and make it Sunday.

#91

That would be a great help in getting the Teledyne wafer probes out, especially if I can then store them at DMS for 48 hours while I make necessary arrangements.

#92

CA would like to see if a vacuum pump is available at the space to be used for several different things. Please let us know.

#93

There is a vacuum pump on the bottom right auto shelves, not sure on its state, never tried to use it.

#94

I have a vacuum pump in my personal stash … pre-Treasure Trove. I’ll bring it in.

#95

I’m picking the truck up in the morning, but I have class until 3 on Sat & until 1 on Sun, so it will have to be after that.

Did you make the trip today? I am sorry I didn’t see this earlier; I would have liked to help!!

#97

A trip to the Science area will answer your question.

#98

The Science Committee H.A.S.T. chamber is in Science.
