Great Amplifier with Ample Cooling for a Good Price
One of the things I like the most about this amplifier is that it comes with forced-air cooling not only on the main heat sink but also into the chassis and onto the circuitry. One of the biggest problems with VHF and UHF amplifiers when used at continuous duty is the fact that all of the heat sinking in the world cannot cool off some of the inner LC circuitry. I have bench tested amplifiers at continuous duty, and, using a laser thermometer, was able to monitor temperature rises of the LC filter circuitry. Even with forced-air cooling of the main heat sink, these capacitors and coils easily and quickly shot up to 130 degrees. I'm sure they would go higher, but I would always stop the test at 130 degrees. Forcing air straight onto the hot part of the circuit is the only way to keep these amps cool for when the repeaters will be keyed for long stretches of time.

Best and Most Accurate Rain Gauge for the Money
Most accurate rain gauge for the money. The only reason I bought it recently is that my old one has had it after 13+ years and over 600 inches of rain in SW Missouri.
The electronic tipping rain gauges are convenient, but, in my opinion, this is the only guaranteed 100% accurate way to measure rain. Period.

Awesome little camera for the money.
You can't beat this little camera for under $20! Grabbed it to keep an eye on pets in a heated shelter that they use during the cold months, and it works great. Documentation is decent, but most of it is self-explanatory.
I couldn't figure out where to find the PC app needed to watch the stream via my PC. There is NO website printed in the manual. Turns out the website address is given when you scan the QR code on the manual and/or the box. On a smartphone, it will automatically lead you to the appstore where you can download the app. But, if you look closely, you will also see it refer to av380.cn and that is where you can download the PC app. I tried to do a direct stream on VLC, but I couldn't do it. So, you will need their PC app. Good news is that it's a very lightweight PC app, and it's very fast-loading and easy to use. It's about 7 or 8 seconds from clicking the app to watching the live stream on both PC and my smartphone. (Slightly longer on the phone when away from the local network - depends on location and bandwidth).
Video quality is decent. Not going to win any awards, but, then again: less than $20, so I'm happy.
The black and white nightvision is amazing considering the price of this thing.
All in all, you can't go wrong with this little camera. Just remember it's not waterproof. And you can't aim it out a window at night because the nighvision LEDs will reflect making it useless. But, for indoor use, you can't beat this little thing.
This is a great little "project" camera. I'm probably going to grab a couple more to allow me to monitor the inside of my garage and an indoor storage area should I need to.
Enjoy!
