LM317T Voltage Regulator with Pass Transistor

If you want to give your 8800GT the "silent treatment" a good option is the $30 Accelero S1 Rev.2 - When I researched this cooling option one of the few recurring complaints were about the lack of a provided heat sinks for the voltage regulators. This mod shows how to use the provided sinks to work for the 8800's regulators.

Hope this movie will sort of show how easy it was for me to wire this Taylor Dunn Electric Car (EV-electric vehicle), itself run by six 12 Volt each, true deep cycle batteries. They are connected by thick stranded wires about 10 inches long, which any golf cart dealership can custom make for you (cheaper), or you can order them online I suppose. Welding shops are great sources for heavy duty electrical cables. I hope I've explained how the solar PV (photovoltaic, dang it google spell check; the word, photovoltaic, is gonna triumph over the needlesly long, separated form goog wants, "photo-voltaic") gets wired the same way, in SIERIES, as opposed to parallel. Sieries connections between batteries, or PV panels ("modules" they are called in the trade) go from positive to negative and negative to positive, yielding double the voltage output. For example, if all six, 6 volt batteries from a golf cart battery bank, were wired in parallel, hooking together positive to positive terminals six times, the out put would still only be 12 volts; sieries gets you a 36 volt output, or 6 volts X 6 batteries = 36 Volts. This Taylor Dunn warehouse type EV, is like almost all golf carts, 36 volt DC current run. the "Neighborhood Electric Vehicles too function, you just add more batteries and panels is all. Or if they get wierd, install a voltage regulator-controller. Once you own the car paid up, they can't stop you from altering the thing any way you want. Banks don't control the laws of ...

You probably are aware that you can use the LM317 adjustable voltage regulator IC as a constant current source, but did you know it can be used as an audio amplifier? Watch the video to see how I made a very simple class A amp.

www.electronicthinking.com Follow along as I show you step-by-step how to solder surface mount devices onto a printed circuit board using just a hotplate, solder paste, toothpicks, and tweezers. If you ever felt that surface mount soldering was too difficult, watch as I position a TQFP44 ATMEGA644 microcontroller, 0603 resistors and capacitors, an SOT223 SMD voltage regulator, and an 0806 SMD inductor onto a PCB and use a hotplate to reflow the solder. Learn how much heat you will need, what to look for to know when it is done, and how to avoid getting burned.

Well we had a little set back but still found time for some fun... the tow truck driver wanted to see what all the fuss was about so we showed him. Little Demoing for the guys at the shop and showing the car up on the lift that i got my new rims and tires from... the guys at the shop were nice enough to let me take the wheels evven though they didnt have replacements. he left the car up on the hoist untill they could get some. not to mention this was taken an hour after they closed...

IN ITALIAN AND ENGLISH ----------------------------------- Semplice regolatore di tensione valvolare, che sfrutta una valvola 6S33S-V (6C33C-B) prodotta dalla Svetlana nel novembre 1970. La 6C33C è un quadruplo triodo (una coppia di due triodi in parallelo, a sua volta in parallelo) di produzione sovietica, utilizzata come regolatrice, con anodo in grafite. Dissipa ben 60W. Ho realizzato questo regolatore (in modo volante) per provare la mia "nuova" lampadina d'epoca OSRAM marchiata Ferrovie Dello Stato, funzionante a 50V. -------------------------------------- Simple voltage regulator using a 6S33S-V (6C33C-B) made by Svetlana in the november 1970. 6C33C is a triode used as a regulator, with a great plate dissipation (60W), the plate is made with graphite. I made this regulator to the test out my "new" antique lightbulb made by OSRAM for "Ferrovie Dello Stato" (our national railroads) working with 50V.

88flak RC infra red gun diorama, 1/18 scale. Using Mitosal mini-ACT-A01 with Tamiya protocol, ELV mini-USB soundcard, 2ch radio, 7.2V battery pack and a voltage regulator circuit (5V for the sound card and receiver). Visaton FRS5 speaker. Impact receiver apple and IR led. The sound samples are triggered using a microservo operating 2 microswitches. The sound card triggers the miniACT to fire. Set at 2 Lives, fires every 3 seconds. The gun rotation is operated through a microservo put inside the gun base. The IR led is in the recoil absorber under the barrel, while a flash led is in the muzzle. Sorry for the poor video direction and shooting, I had to control too many things by myself. rctankir.forumattivo.com

The controller is regulating battery voltage now. Target voltage has been set at 14.2 volts. The display LED shows a PWM simulation when target battery voltage is reached (this doesn't show up too well on the video), and a series of flashes when it's below target voltage. 1 flash for 11 volts, 2 for 12 volts, 3 for 13 volts etc. It also shows a series of rapid flashes if voltage drops below 10.5 volts. The LED can be turned off altogether if desired to save power. With the LED turned off, the controller takes very little current - about 0.5 milliamps, that's just 500 microamps! Future developments will include detection of excessively long cables between the battery and the controller or excessive current flow. Also voltage measurements will be more discriminating to get a more precise, more stable feedback control. Part of 'designing a solar charge controller' at www.256.co.uk

www.vintagecollectiblememorabilia.com has acquired a 1920's Master Violet Ray. This medical therapeutic device is also called a Quack Medicine Gadget, for reasons of having special effects but no medical healing powers. Unique and hard to find in working order in this condition; all parts are present and both clear glass tubes are in perfect condition. The main body, massage unit, plugs into a 110 volt 20 amp. outlet, (household plug) and has a voltage regulator knob on the bottom. Adjusting the voltage knob increases or decreases the neon violet ray's intensity. Resembling lightning or sorcerers magic ball, as seen in science fiction movie, this gadget would be a great piece to add to your collection.

Variable Power Supply using lm317 adjustable voltage regulator and lm7805 5v voltage regulator (for digital read out). Homemade printed circuit board with transformer in mineral oil bath. Made for an electronics class using parts mostly from Radio Shack. The printed circuit board was made using a presensitised board and positive developer. A standard acid etchant was used after that.

Help! I've been bitten by the vintage stereo equipment collecting bug...here is another 1980s Technics stereo receiver in good working condition. From the looks of it, this was a highly basic model. It offers only 25 watts per channel of output power into an eight ohm load, tuner, tape play/record and turntable inputs. There is no AUX input, although the tape playback input can be used as such. I need to clean up the tuner memory backup battery holder. There is also a capacitor on the main board that looks to have been a little warm, as it was leaned up against a very hot voltage regulator. I may replace it. I also removed a ton of dust from the inside.
