I plan to build some vacuum gear and have wondered about using a vacuum pump to maintain vacuum after using a shop vac to remove the bulk of the air. Plan would be both connected with a check valve on the shop vac so it can be shut off.

The tower easily absorbs what appear to be full effort movements while trying to to dislodge the Venus. It must be an interesting sensation. Have you ever lifted the frame or had a platform for the feet that can lower to leave the 'victim' fully suspended?

This was the main problem. Water got into the battery control board. Fortunately the battery did not overheat. Wow that could have hurt. Both batteries did puff up.

Yes. So yes.

There was not a large amount of water but you can see the rusted screw and there were corroded components on the bottom of the board in areas that are constantly powered. The large coil is for the wireless charger. Hopefully the Cellblock 3 I've ordered will be better.

..... from the force of the lever arm pushing up on the cover at the top right of the image. The battery must have shorted because it was completely dead. Connecting the charger would allow Bluetooth to connect but would not unlock. I had to use the emergency release.
