Lab Power Supply

this is a homemade lab power supply. 2 - 32 volts 4amps. it is based on the lm723 regulator on a home made printed circuit board. the transformer and caps came from axeman surplus store. the meters came from some really old equipment. the amp meter has a homemade shunt. the case is made from the shell of an old microwave. a shot goes out to my uncle that helped with the case. here is the schematic i based it on. hmin.tripod.com

steam1

A view of my steam powered USB charging device powering my iPod. This is a Jensen #75 connected to a lego Technic motor via a rubber band. The motor is being driven and so it acts like a generator which feeds into a voltage regulator circuit to give a continuous 5V to the iPod (or any USB device).

Building a variable voltage mod personal vaporizer (e-cig) is easy using a pre-built module. Instead of showing you how to do it with individual components as on my last vv video, this one uses such a module. My original video was 50 minutes!! I had to cut it way down so you wouldn't get too bored watching it, lol. Here's the parts list of what I used to build this mod and the links to get the parts: Elmo Light Chaser toy - I got it for $1.00 at my local thrift shop. Variable Voltage Module - DC-DC IN 3-30V OUT 1.3V-18V 3amps 20watts 1.5"x1.5" .6" - ebay $9.99 cgi.ebay.com All the rest can be bought at madvapes.com: Battery connector 510 with big hole $1.99 Battery Voltage Indicator $6.99 SPST latching switch for LCD, different than what I use in the video but probably nicer $0.99 Uses two PROTECTED 14500 3.7v 900maH Lithium Ion batteries. The ones I'm using here are the Trustfire brand. ALWAYS USE PROTECTED BATTERIES. Intro music by Kevin MacLeod - Thank you Filmed with two Kodak Zi8 cameras Edited in Windows 7 with Windows Live Movie Maker Thank you very much for watching.

If your bearings, housing, or spindle are not messed up then just replace the regulator and points! This has worked for me at least 6 or 7 times. I hope this works as well for you guys as it has for me!

Typical surge strips may offer some protection from small surges and spikes, but they can't protect from catastrophic surges or sustained overvoltages (commonly caused by wiring faults). See how a Furman power conditioner with EVS protects and what happens to a typical surge strip. More information available at www.furmansound.com

Bridge rectifier is an electronic component which converts an input AC current into a DC current as an output. Electronic devices, and particularly portable electronic devices such as portable computers, cellular phones, and personal digital assistants (PDAs) typically make use of alternating current to direct current adapters (AC adapters) either as a direct source of power, or as a source of power to charge on-board batteries. Bridge rectifiers are used to rectify current output from alternative current sources, such as an alternating current generator. Three-phase bridge rectifiers have been provided for rectifying a three-phase alternating current to convert it to a corresponding direct current. The rectifiers generally comprise a three-phase rectifier circuit including six three-phase bridge-connected diodes and a smoothing capacitor connected between DC output terminals of the rectifier circuit. The six pulse bridge phase controlled rectifier is a widely used type of solid state power converter which is used in industry for converting a three phase ac input voltage to a variable dc voltage. The six pulse bridge phase controlled rectifier uses six thyristors as controllable power devices. Bridge rectifiers for motor vehicle alternators generally include two metal parts used as heat sinks that are electrically insulated from each other. The Bridge Rectifier When four diodes are connected as shown in figure 4-8, the circuit is called a BRIDGE RECTIFIER. The input to ...

Amorphous crystal solar panel provides superior performance in bright sun and in partial shade. Use this solar panel to power an appliance, light, small motor, or battery, but you must use a voltage regulator (not included) between them to prevent overcharging the battery and consequent damage. This solar panel may also be used to maintain the charge of batteries which are powering other items such as a car radio while the car engine is off. www.harborfreight.com Harbor Freight Tools Quality Tools At Ridiculously Low Prices Sign up to receive our special promotions and coupons pref.harborfreight22.com

Model No. 15A:- The main objective of the project is designing an automatic washing machine for programmable sequential switching of motors using embedded system based micro controller concept. The development of this application requires the configuration of microcontroller architecture that is the selection of the machines, and writing debugging of the application program. In this project, the clock plays an important role, where it is used in the following mode ie, the set mode, auto mode and manual mode for controlling different machines. In set mode, through the digital clock the machinery will run based on/off and on time where as in auto mode they will run by default settings and finally in the manual mode the real-time systems. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

with Henry Zhang, Applications Engineering Manager - Power Products video.linear.com Current sharing performance is critical for PolyPhase® DC/DC converter to balance the thermal stress and properly size the power components. The PolyPhase converter can be controlled by either voltage or current mode control scheme. With voltage mode control, the active current sharing is achieved with a complicated external current sharing loop, which is usually slower than the inner voltage feedback loop. With current mode control, such as implemented in the LTC3731 or LTC3850, the current sharing can be implemented very easily with its fast current loop.

The EZ-B Robot Controller was designed by Canadian Roboticist DJ Sures, who is the creator of popular robots: Autonomous Wall-E, Award Winning 3-D Environment Mapping K-9 and the Autonomous Cookie Monster. Combining his robot knowledge and experiences, the EZ-B was designed as an all-in-one solution. The circuit board contains a powerful voltage regulator, a bluetooth antenna module, digital I/O, ADC, servo control, serial ports, MIDI connection, TellyMate interface, and more! This robot controller supports the EZ-Builder software interface to control your robot, without even needing to program! Watch the EZ-Builder Video and see how easy it is to add Camera Color Recognition to your robot without writing any code! For those interested in programming, the .Net EZ-SDK exposes the EZ-B features. Including color camera recognition, voice recognition, voice synthesis, midi control, and more. You can quickly recognize how the EZ-Robot Project was designed for reusable flexibility. Build many DIY Robots with a single EZ-B Controller by simply moving the board between projects.

This is an 8-bit ALU that I created by connecting two 4-bit ALUs together. There are 48 plus a few more operations available (I don't know how to use the comparators). There are 16 logic functions and 32 arithmetic operations. Components used (excluding the voltage regulator): 2x 74LS181 - 4-bit ALU 1x 74LS04 - Hex Inverters 2x 8 position DIP switches 1x 4 position DIP switch 1x 2 position DIP switch 9x LEDs (1 Green, 8 Red)
