LM317T Voltage Regulator with Pass Transistor

This is a short video of the early testing of my new GAVR-15 AVR on my ST-10 Generator. You can see clearly it self starts easily with no capacitor or ballast required. The voltage regulation is nothing short of excellent, even handling a large bank of fluorescent lights on their own with no noticeable flickering. The other regulators I have tested have all needed an additional load such as a heater or similar before they could make a stable voltage while running these lights. This shows how well filtered this regulator's circuits are.

I apologise in advance for the shaky video during engine starting. I simply didn't have enough hands! This is the initial test of a boost circuit I made to assist with getting an initial field on my ST-10 generator with its output powered voltage regulator. The 9 volt battery is used to "kick start" the field in the event that self excitation is insufficient. Some ST-10 generators (including mine) do not retain enough residual magnetism to start generating when using an output based voltage regulator such as the GAVR-15. This circuit appears to have completely overcome that problem.

This is a detailed walkaround showing the progress to date of my "Daisy the Diesel Project". It was named by my 5 year old Julian who loves watching "Thomas the tank engine" I bought this wonderful engine in Australia from a company called "Ozlisteroids." Their website address is www.ozlisteroids.com Buying this engine was the beginning of a project that just kept growing and growing. The engine is an indian clone of the famous Lister CS "cold starting" 8/1 diesel engine. This particular one was made by the folks at JKSON diesel. It is an 8 hp model, making its power at 850 rpm. Here is a bit of a rundown of what has been done so far in this project. * Stripped down to every last nut and bolt to permit proper cleaning out of the casting sand that we always seem to find in the indian made engines. * All paint and indian body filler removed, then repainted in colours of our own preference instead. * Built a frame to mount it all on, then set about finding and building on a number of interesting things for it to actually drive. There's nothing more boring than looking at videos of all these beautifully restored engines on youtube, which are doing nothing but turning themselves over and looking pretty! Diesels love to work, don't they? ! Well this one gets to work hard, and regularly. No glazed bores here... The two major objects driven by my engine are a heavy duty 240 volt alternator and an air compressor. The air compressor is a brand new 1950's made Bendix-Westinghouse ...
