I purchased a non-working Motorola R2210B/HS service monitor just to take a look and see if it was repairable. Part 1 of the video is the teardown of the basic unit and troubleshooting the LVPS section.
I put this together for testing. Package download is below (At Very BOTTOM). You will need to homebrew a non-standard ngspice (doesn't have ngspice lib by default). Its avail here https://raw.githubusercontent.com/jmaibaum/homebrew-core/8ac02ae933c4cd5d1f661b6a2bda2f429d5f1e87/Formula/ngspice.rb . Note the NGSpice homebrew is in flux and this version is done jmaibaum.
Operation and Teardown of a Motorola R-1150A 1980's Tone Synth.
How-to get a great soldering system setup. Buying used Metcal and Thermaltronics to assemble a great soldering system. I've been over my Metcal setup in an older post but this a video of the setup and how to get what you need for a great setup.
Video of how to take the Wouxun apart, complete down to the board level. Overview of repair areas.
Long term review of the Grizzly G4003 Lathe and some bonus footage of the 3617 Mill.
How-to build a parallel cable and accepting the danger of a dead man's cord. Understand this and its risks if you decide to build it! Best rule of thumb everything stays connected when any of the generators are running. Always shut down all generators before making connection changes.
I needed a generator for a weekend camping trip and after some quick research located a locally sourced (Walmart) unit that would be somewhat of a gamble. It is a Powermate 2000i. Specs show output to be 2000 watts surge and 1600 watts continuous. I couldn't find much info other than a pulsar brand review which appeared to be the same unit. After picking it up and getting oil in it (they even gave me a funnel) I was pleasantly surprised to its quality, low sound, and output. I've used it now for 2 weekend trips and have purchased another unit that I'll be operating in parallel now that its A/C weather. The parallel connections are standard banana jacks but I'll likely rig up a dead man style direct to 50A plug for convenience and keep a sense of danger with me while camping. I'll likely show that as well but its a use at your own risk type of thing.
A quick how-to on changing oil for a Polaris RZR S 1000. Big improvement over the 800 S models.
Installation and review of the Polaris RZR S 1000 Heat Shield Recall. Overall it appears to redirect any fuel spilled in the bed. The shield behind the seat is improved with a rolled edge where the old shields tended to melt the interior foam.
