Entry 044: Zipping Up the Axle Boots

When the teardown stops and things start going back together, you know you are making progress. I am definitely at that stage now.

Entry 043: Painting the Small Parts

I have been sandblasting like crazy. That sandblasting cabinet I paid too much for is so convenient. I guess it was worth the money. The only problem I have with it is being able to see what I am doing inside. I have a vacuum set up to suck the dust (created from the break down of the sand) out of the cabinet, but it doesn't fully solve the problem. In fact, I have to clean the filter of the vacuum after only a few minutes of sandblasting. I should build a cyclone filter to take the fine dust out before it gets to the shop vac, but for now I will continue plodding along this way.

Entry 042: More Coats

I put a couple more coats of paint on the chassis. I think it looks pretty good, especially considering a farm boy was holding the paint gun. I'll let you judge for yourself.

Entry 005: Testing the Whichamathing

Now that I had the probe stuffed into the cistern and the connector soldered on, I figured I should connect up the whichamathing and try it out.

I connected the power cable as well as the DE9 connector.

Entry 004: Installing the Thingamabob

The side deck on our house covers the cistern. There is a hatch in the deck over the pump casing so we can pull the submersible for maintenance without moving the deck.

Entry 003: Building the Meter

Since the prototype was a huge success, I got to have some fun burning myself with the soldering iron.

Entry 002: Prototyping the Circuit

I went to my local industrial electronics supplier and picked up a few things. He had the NTE4066B quad bilateral switches in stock so I picked up a few of those. Since the schematic calls for a +6V supply rail, I grabbed a NTE962 fixed 6V regulator. I also got a few other odds and ends that I didn't have lying around in my junk pile.

Entry 001: An Intricate System of Pipes

As mentioned earlier, we get raw water from a local reservoir at a slow rate. For water storage we have a cistern that holds approximately 12000 imperial gallons. From there the water is pumped into an intricate system of pipes running all over the place. I am sure you don't want to listen to me rant about our complex water system. I think my father is the only person who really understands what every valve does. Anyway, we needed a way to tell how much water was in the cistern and just like that this here project was born.

Entry 041: Painting the Chassis

Painting has to be the thing I dread the most. (Sandblasting would be the only other contender.) It is a skill that requires a great deal of patience and sometimes I am just not patient at all. My lack of patience causes me to put too much paint on, causing it to run. At that point I think, "I can fix those runs if I spray a little more paint to smooth it out." You can imagine the runs just get progressively worse. Phooey!

Entry 040: Chassis Reinforcing

Since the chassis still has no paint, I figured now would be a good time to do a little welding.
