LM317T Voltage Regulator with Pass Transistor

Schematic used: www.uoguelph.ca Servo used: Yeah Racing SV-0006 Micro Servo Notes: - 850k substituted for R2, that's all I could find - 0.0271uF substituted for C1 (was unstable at 0.027uF; 273+101, again, all I could find), works fine but as you may be able to see/hear, center is offset to the right (100% right in servo is 80% or so right in circuit) - Diode is to prevent reverse polarity, and also used to clip negative to (crude on/off switch) - 7806 voltage regulator underneath servo plug - We got a coqui frog in our backyard ):

This is my "Table Candle II". It is a small battery powered flourescent light. What is different about it is that it uses a regular inverter circuit with an adjustable switching voltage regulator. This regulator allows for better control of the light output and power consumption.

Cb350 Honda Chopper My son and I built. This bike began as a stock 1973 Cb350, with both kick and electric start. Stats include: Twisted 12 over twisted springer front end with modified rockers to give proper trailing. The springer nuts have been replaced with saints crosses that use to sit top of fenses in old grave yards. The tank is made from 16 ga. steel with 20 ga. hammered steel skull molded to the top. With an old school filler bung. And an old school spiked fuel cap. The torque bar on the rear wheel is made from a stainless steel sword. Rear brake pedal( only brake) was made from a pair of brass knuckels. The sprocket cover was made from a skill circular saw blade. The shifter was made from a 1947 fleetline aerosedan parking brake lever inverted. With the top controls being from a 1978 YZ650 handelbar set. The dice on the top belonged to my father, probaby one of his old sleds in the 60,s. (RIP pop) Also this shifting setup incorperates the clutch on the actual shift lever. This way the clutch is actuated with the same hand that is shifting and not with the left foot that is common with jockey (suicide) shifter setup. The frame was fabricated by my son and I using the original CB350 engine cradle. The neck was the original from the CB350 inverted 180 degrees which allowed me to weld the neck stem to the top springer plate and put the nut on the bottom. Trick was putting the bearings in because I used the original loose bearings. However leaving part of the ...

electrionic dice, made on a pcb. Shortly described it consists of 9v battery, the TS7805 Voltage regulator, the ne555 astable multivibrator to produce a clock signal, a Xilinx XC9572 CPLD (Complex programmable logic device), 7 diodes, a push button, and a couple of capacitors and resistors. The CPLD is programmed with VHDL from Xilinx ISE.

My 1970 Opel GT. I have had this car since 2000 and have since redone all the suspension with urethane bushings and sway-bar ends. Installed electronic ignition. Replaced the transmission with a BMW 5 speed. Replaced the carburetor with a 2 barrel Weber. New muffler and resonator. Replaced alternator and voltage regulator. New master cylinder and vacuum brake booster. Installed CD player and stereo speakers. Replaced all window seals, door panels and carpeting.

Test flight of a backup FPV twin boom all weather camera plane. Used the video gear from the original Grey Ghost including the antiquated ACT-Labs Black Box OSD. The airspeed pitot isnt installed and the altimeter wasnt set, I was overloading the voltage regulator it would only give me 10-11 volts. I think I will eliminate the black box osd all together. This is a mix of two flights, the first one I was staying just below the cloud deck, the last one the rain started coming down pretty good so I landed quickly. No gear got wet, the camera in the nose is siliconed good. During the landing you can see the big drops starting to fall.

Riding my bandit 400 at a HRC Rider Development Day at Taupo on the 20th August 2007. First time back on the track since May 2006, heaps of fun. :) The trackday is split into 3 groups, fast, medium and slow. I was in medium. Apologies for the audio. I didn't have time to sort out a microphone and didn't expect it to record any audio, but it did. I'm not sure how. The camera is a no-brand cheap CCD security bullet camera. The guy I bought it off isn't selling them anymore, but www.viewtech.co.nz looks pretty much identical. The video from the bullet camera was recorded on a jxd900 portable media player. In later videos I used a mic made from approximately this circuit: www.reconnsworld.com The jxd 900 is the limiting factor in the video quality, it only records 320x240 pixels. camera is good for more. I also made a small voltage regulator to run the camera and mic off the bike's electrical system (not sure if that was needed).

Digital Voltage Selector www.jakeselectronics.net I wanted to write a program for a 16F84A to be able to select different voltages by the press of a button. How it works, Each time the button is pressed the PIC scrolls through output pins (putting them high, one at a time. I'm using 3 pins) Each pin is connected to a transistor. When selected, the appropriate transistor pulls a resistor into play, with the reference pin of the LM317 (variable voltage regulator) and in turn changes the output voltage. At the same time as scrolling through the 3 different outputs (or simply setting one of the 3 output pins high, the chip tells the LCD to display the set voltage. (In the video the LED's up the top of the board are simply showing which pin is high, RB5,RB6 or RB7)

Disclaimer: unfortunately I cannot be responsible for damages to your equipment as this is not a common rapier or service procedure and you will be using non original parts that said if you follow the video to every step and make sure you are confident you have the correct parts youll be fine. (Sorry just covering my ars) This is a video showing you how to replace the little pop up target light on the front of your Technics SL MK2 turntable to an LED. the advantages to this are, the leds draw less power, they are brighter, they have a longer life span and as an added bonus they work out cheaper in the first place. By the way the leds on my decks look blue but they are actually white, they look blue on the camera because they have a high colour temperature. Order codes: Order code for maplin led: N28BY = WHITE. N30BY = GREEN. N33BY = SUNSET ORANGE. N31BY = BLUE. N32BY = YELLOW. Order code for maplin voltage regulator: QL31J = (PART NUMBER: TS7805CZ) OR UJ54J = (PART NUMBER: L78S05CV) When ordering the voltage regulator be sure to check the part number on the part its self to insure you are getting the correct part. Order code for Radioshack voltage regulator: 276-1770 = (PART NUMBER: ML7805A) WANINGS: Dont have the turntable plugged in while you have the plastic case off, i did the test with the multi-meter so you dont have to. Check and double check that there are no short circuits before powering up your turntable, and never allow a short circuit to occur in the lamp ...

Using the LM317LZ 100ma adjustible voltage regulator and one resistor, you can make a constant current source. With the LM317 1.5 amp version, you can make one with higher currents. I made an error during the video: I said volts when I mean milliamps. (you probably figured that out though).

This is my homemade miniature elevator controller, using relays! it drives a TEMIC 24VDC motor, and its runs on a HP 18V 1.1A power supply, from an junked inkjet printer. The motor runs on the full 18 volts, and for levelling it runs on 5 volts, using a LM7805 voltage regulator. the levelling switch will be replaced with some more microswitches when i begin building the real elevator shaft. the buttons are : up to floor 2, down to floor 1, emergency stop.

Designers of today's systems with battery supplies and common 3.3V and 5V rails are faced with the challenge of powering devices that require higher voltages to operate, such as displays, line drivers, rotating media, RF amplifiers and backlights. For example, some peripheral displays in portable applications use backlighting with 5 leds that need 15V to 20V to power the string, but a typical battery configuration may only provide 4V to 8V. Nationals latest boost and buck-boost regulators give designers the ability to achieve the output voltage necessary for these peripheral devices. In addition, with excellent performance-to-power ratios, the high-efficiency boost and buck-boost regulators fall into Nationals powerwise® family of energy efficient products.
