Good idea to pull the batteries. Didn't work, though. Not sure what the right way would be to discharge the alleged capacitor. I might try to remove the batteries and then short the DC + and - together. Otherwise, I'll have to take a look inside.
"I've noticed at our local Walmart that as I push some of the carts, I get a static discharge through my hands. It's really uncomfortable. Have other's noticed this same problem?"
Often you will see some versions of shopping carts with a discharge strap or small chain hanging down rubbing the ground. This also seems to be a greater problem with the newer plastic carts than the older metal carts... There has been alot of info about this problem with a specific retailer which you can find by searching: Wal-martshopping cart static electricity shock.
I once worked for a contract ICT test house developing test programs and fixtures. Our test head (HP3065) and debug bench was in a "static controled" room with a disapative carpet. One day durring the winter, I walked accros that rug, reached down into the empty patch bay of the test head and drew a 1" arc to one of the test card connections; it hurt like heck and I jumped back. I immediatley grabed the diagnostics fixture, and found that we had a dead analog card. It took two day of down time for HP to find the problem and get us a replacement card. So much for the anti static carpet. We got a lot more serious about wrist staps after we learned that we could not rely on the carpet any more.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
