LM317T Voltage Regulator with Pass Transistor

Part 3 - Be classy and regulate! Using an LM317T based voltage regulator, we'll keep a consistent 7.5v going to that other positive pin. Hang in there, we're almost done...!

Come visit the website: www.h2o2fromh2o.oregonsouth.com Update Original Release The idea is to control the Voltage within the Cell. Using the internal resistance of the cell it self. From my research on neutral plates, it will only have to make minor adjustments to each cell, mostly on the outer most cells. The Zener Diode really represents the placement of a regulator, but is the simplest of the regulators. A Zener will still have to handle some current. Not sure how much. Maybe more then what Zeners are currently made to handle.

Just how different are linear, LDO and switching buck voltage regulators? I'm glad you asked! You might be surprised... It's tutorial time. NOTE: There are many different methods of SMPS control, this is just one of the simple ones, go investigate! The EEVblog Forum: www.eevblog.com The EEVblog Website: www.eevblog.com

This is a video of an LED Lamp Modulator circuit. The purpose of the circuit is to flash an LED lamp such as is used as a brake light or even a turn-signal on a motorcycle in an eye-catching way to increase the conspicuity of the motorcycle. The circuitry is very simple: A 7805 5V linear voltage regulator, a PICAXE 08M microcontroller, a TIP31 NPN BJT power transistor to drive the LED lamp, and a few resistors and one capacitor. All the "work" is done by the program in the microcontroller. This video shows modulation pattern v1. The pattern can be changed by editing the control program using the PICAXE program editor. The 'v1' program occupies about 62 bytes out of the 08M's 256 bytes total memory. Theoretically, I could fit anywhere from 1 to 4 modulation patterns and use a switch or jumper wires to allow the user to select the desired modulation pattern. The circuit is easily modified to operate off of the license-plate lamp circuit. This would allow it to light the LED lamp at 20% or 30% brightness when the brake is not being applied (the behavior of automotive brake lamps) and still flash when the brake is applied.

www.cobalt-minor.co.uk Alternator repair and rebuild part 3 is some footage from the dvd that we film showing 3 different ypes being rebuilt. One lucas alternator, one Delco alternator and a Lucas dynamo rebuild. I show you how to change the alternator bearings brushes rotor commutator casings stator magnet the lot. You will that basically the only "special tool" rrequired is big enough soldering iron which you will need to replace the alternator rectifier and on some alternator the voltage regulator. The dynamo is easy except for a special spring clamp but thats not always needed. We show you how to check the rotor windings without special tools and also you see an accident I have with the hammer so you'll see what not to when you are repairing or rebuilding your rotary components.
