Cheese-Wiz for cold weather dog training

use canned squeeze cheese as a dog treat to avoid bare hands in cold weather

I take no credit for this idea. It comes from the Training Director at Fieldwood Dog Training Center.

Positive dog training means always being ready with a reward to the right behavior. If your dog is food-driven then you probably carry treats. Most treats are small and that means using your fingers to dole them out one at a time.

When it’s cold outside, gloves or mittens keep your hands warm but make doling out treats a real challenge. Using canned cheese is easy and can be done with gloves on!

If it’s really cold out, the can will gradually become slow to dispense cheese so keep the can in a warm pocket.

Lightning at 240 frames per second

I took a few moments to watch some exciting lightning the other night. Without much though and even less effort, I whipped out the iPhone 6 and switched it to slow motion video and was lucky enough to capture a couple lightning strikes.

After seeing the results I wished I’d been more involved and fetched the tripod and waited for some of the more spectacular events.

A $35 paint gun that’s good

good HVLP paint guns need not be expensive

Three years ago, I walked into an automotive pain shop and asked if they could recommend a good paint gun. I’d been using a cheap one and my results showed. I decided I’d better get a good one, even if it would cost me $150 or more. I’d read the reviews and most were suggesting a $210 spray gun.

The older gentleman at the shop said, “I can sell you an expensive gun but this is what we use” and he pulls a plastic wrapped run off the display sales shelf. The AES 507 was just $35.

The man also asked how I cleaned and maintained my paint guns and then showed me a simpler way. I took the gun home and used it for EVERYTHING.

I shot lacquer and urethane and epoxy and even latex. The results on everything from wood to aluminum were great. The latex took its toll on the gun and while it still works well, I decided I may as well pick up a new one for the next project. (I relegate the old one any latex paint projects.)

I prefer an aluminum hopper and will likely transfer it across to the new gun but the plastic works just fine.

The quality and quantity of the air supply is important as is the condition of the space you use to spray. All those being equal, you don’t require a high end big ticket gun to get great results.

What’s It #21 – an RF dummy load

RF dummy load for transmitter testing
RF dummy load for transmitter testing

I’m about to start testing a remote COMM radio. To verify the radio it will need to transmit.

Given these tests, the general convenience of having a transmitter test load, the relative easy of acquiring parts ( & assembly, I decided to build rather than buy.

The design consists of 20 1K ohm 3 watt resistors all in parallel. This total 60 watts at 50 ohms. This is submerged in a quart can of oil to dissipate heat. The effective rating is safely 120 watts and higher loads for short transmission.

The total cost was $12 for one hundred resistors, $7 for five BNC connectors, $1 for each of the quart paint cans, $9 for a 6″x6″ sheet of 20 AWG brass, and $2.75 per quart of light weight motor oil. While the two dummy loads technically cost me $17.75 each, the next two (if I needed them) would only cost me an additional $3.75 each.

What’s It #21 ?

I need two of these and rather than spend $40 – $50 each I decided I’d build them. Here is one.
