2014-07-30 (Tha) Sous Vide Oven V2.0 COMPLETED




To waterproof the temperature probe a ½” copper pipe, two fitting copper caps, and a 7mm hex nut were purchased. A ¼” hole was drilled in the center of each cap end. One cap was held against a board for stability and four more holes were drilled perpendicular to the hole in the center of the cap end. The burrs from the drilling were cleared out with a 5/8” drill bit inserted into the cap and spun. A piece of ½” copper tubing was trimmed with a pipe cuter. The smooth factory edge of the copper pipe was left exposed while the sharp, freshly cut, end will be kept near the end cap instead of reaming the inside.

The temperature probe was pushed through the pipe. Silicone was applied to both sides of the hollow bolt to seal it and keep it stationary. The sealed probe was inserted into the holes of both caps, held end to end, so the single-hole cap could be attached to the pipe still covering the probe. The 7mm nut was attached on the five-hole cap side and tightened with a hex socket. The single-hole cap was filled with silicone, touching the edges and covering the probe, before being pushed onto the pipe. No solder was used but a lead-free solder could seal the copper to copper seals.

2014-07-29 (Tu) Charged: DesertIrish

Dawson doesn't find out what Shana hears on the phone but she agrees to leave with him in The Flying Machine. Dawson demolishes the abductors' van by flying through the windshield with The Flying Machine and lifting the van by the roof. Once clear of the city Dawson allows the van to fall onto a stretch of desert. A confusing flight is made to Canada before traveling back east and south to North Carolina. Dawson makes a supersonic maneuver but passes out from the resulting boom. Beforehand he instructs Shana to cover her ears so she is fine. When Dawson wakes up Shana is flying them to North Carolina while steering clear of seaward ships. Her notable vision is hinted at. They safely return to the dock after dinner, North Carolina time. Jason says The Flying Machine was only tracked as far as Montana. Dawson is exhausted but resolves to get Shana sorted out first. This is not the first hint toward Dawson's indomitable will.

2014-07-28 (M) Charged: DesertIrish



Dawson woke up before everyone else at Heather’s hotel room. He fetched breakfast from the hotel’s continental breakfast and asked everyone to meet at the dock in two hours. He and Head shared a cab and left Motor and Heather. Heather’s mood darkened and she snapped at people. Dawson talked to her and found some common ground for a little while. For the point of the story she was sick of being the only woman in the group despite being the center of attention which she usually enjoyed. Head and Jason worked in the sub all morning taking measurements while Jason constructed a 3D model visible on a computer running near the flight simulator where Motor, Heather and Dawson were working. During lunch Jason privately told Dawson that Shana, Exposure, needed to go into hiding. Jason’s kind nature urged Dawson to ask everyone at the dock if they would accept Shana there. Heather was the first to agree, to Dawson’s surprise. Head was the last to agree and only did so when Jason assured him she wasn’t spying for anyone. Dawson left in The Flying Machine, took a circuitous route, and landed in Arizona where Shana was sleeping in her escape van. At Jason’s advice Dawson slipped his cell phone through an open van window so Jason could speak with Shana.

2014-07-27 (Su) Conductive Paint Experiment


The response to my conductive paint experiment on sites like Hack A Day and Instructables.com has been phenomenal so I have kept experimenting with different parameters. Today may be the last day but then again someone may suggest something else that makes me want to pick up and try some more. I won't force it either way.

Someone on Instructables suggested mixing graphite powder with paint medium which eliminates paint pigments which may interfere with the resistivity. As it would happen, my roommate, who gave me the idea to start this experiment, had some gel medium which she donated to the experiment.

Enough background.
----------

Black acrylic paint was purchased but the pigment is unknown. Ideally the pigment would be carbon. A swatch was painted on Friday and allowed to dry. No measurable resistance could be measured on the pure paint. The goal is to test two more substances with graphite powder in the same manner as the first three experiments.

 Materials for this experiment

Graphite powder was added to two jars. Black paint was mixed into the first jar at a ratio of approximately 1:1 by volume. The mixture was stirred with a toothpick. Once mixed a single heavy line was drawn before the toothpick was wiped off in the jar and allowed to dry next to the sample.

Gel medium was added to the second jar at a ratio of approximately 1:1 by volume. The mixture was stirred with a toothpick. Once mixed a single heavy line was drawn before the toothpick was wiped off in the jar and allowed to dry next to the sample. The gel medium and graphite powder required more laborious mixing than the black paint and graphite powder.

The samples were allowed to dry for five hours. No resistive reading could be taken from the gel and graphite powder after hours of drying. The black paint and graphite powder had acceptable readings.
