Adjust the boost converter to output 12V.

Since all the components run on 12V take the output of the boost converter and connect all the negative and positive wires to it, this way, when the switch is pressed all the components turn on.

The output of the boost converter is connected to the three pumps and the solenoid valve.

Many materials were used to make the gasket that creates the vacuum, foams, silicons... Surprinsingly the one that worked best is gecko tape, which is relatively cheap and readily available.

To make the gasket, stick a 100mm long strip of gecko tape to the plate vertically, this should cover half of the plate since the tape is 50mm wide, stick another 100mm strip to the other side. Use an x-acto knife or similar to cut the shape of the gasket leaving about 5-7mm from the edge and leaving the screw holes covered.

Repeat the process except this time the tape is placed horizontally, this gives us a 4mmm thick gasket for the vacuum to form.

The tape will get dirty and less sticky with use, do not worry, from experience this doesn't affect the holding power of the glove.

To use it put on the glove and make sure the straps are secured to your elbows.

Then place your hands more or less at the same height on a flat surface, use your thumbs to power the glove and wait a few seconds for the vacuum to form (usually you will hear a change in the sound the pumps make), then raise your feet and you should be stuck. YOUR WEIGHT GOES TO THE STRAPS, NOT THE GLOVES.

Technically you can't climb since you need both gloves to stay stuck but I have been thinking on adding some suction shoes, suggestions and advices are welcome.
