    Mini Kite

    Great Idea!Back in the sixties we used to make fighter kites similar to these.

We used double cotton rag 1/2 inch wide and about 5 to 6 feet long tails. one shorter than the other, about 3:1 relation. Nobody ever explained the reason for a double tail, but it worked!

  • Making a controller for a shower water heater.

    FYI The best part of it is that it works at very low water pressure (7psi and up). The instalation instructions prescribe a flow restrictor (included) for water pressures above 20psi

    Hi! I have been using this type of shower head for over 25 years with no incidents! We use a Venezuelan design - Corona / that relies on water pressure to turn it on and of. This shower head provides two temperature levels (2.5 and 3.0 kw). The switch is actioned by a rubber diaphragm that isolates the switch from direct contact with the water. Both heater elements and the diaphragm switch are available as spare parts. I have gone thru two heads (Actually three, but the third one was destroyed by a lightning bolt that struck about 20 feet from the shower. fortunately nobody was home at the time) We do install them on a dedicated circuit with a dedicated grounding bar! Other than cleaning and inspection about every 6 months, nothing else has to be done. I do keep a full set of spares, AN...
