Working on the Potato Gun

Yesterday, Andrew called me and he wanted to finish working on the fuel meter for his potato gun. This fuel meter allows a precise amount of propane gas to be injected into the potato gun. The response of several people when they heard we had made this was "You guys are idoiots, that is not safe!" Right there is where they are dead wrong. Using propane in a potato gun is much safer than using household aerosols, gasoline, etc.

• Propane burns to produce only CO₂ and water. Aerosols with all kids of chloro-this and fluoro-that produce nasty organic pollutants when they are burnt.
• It is more efficient - The propellant in aerosols is propane and butane anyways, so there is no difference.
• Many of those aerosols may degrade the PVC gun making it weaker. Propane isn't going to do that.
• Metering the gas through a special device makes sure that only the necessary amount is put in.

Anyways, we took some pictures...

The first stop was Cole's Hardware and Lowes...to get the few remaining items we needed to build the propane injection system.

We came back from there, with what we bought among these items:

After the propane injection was built, it was time to go Southwest to Freeburg...where there is much open space. On the way out, we encountered a telco crew in the process of stringing fiber optic cable, probably to bring them DSL.

Now It's time to test the thing, plus a few other devices...

They switched to DirecTV a few months ago. DirecTV's free installation included removing the old dish from the house, throwing it on the ground, then connecting the cables to the new dish but just leaving it sitting on the roof without bolting it to the house.

The old dish was still laying around, so Twity decided to beat the crap out of it...

A true Via Cable Moment!

Being out in the middle of an open field, there are many spiders near the house...
