from pedalpowergenerator.com Pedal Power experiment conducted on the Leeson M1120046 DC permanent Magnet Motor to find out how fast a person needs to pedal to get 12 to 15 Votls DC output needed to charge lead acid deep cycle batteries or powerpack. Experiment performed by Brad at pedalpowergenerator.com This DIY video shows you how to create a DC Voltage output curve of the Leeson Model M1120046 permanent magnet DC motor used as a bicycle generator. Data is collected on a test fixture with a 1 horse power variable speed drive motor that simulates a person pedaling a bicycle at different speeds. The speed is measured by a tachometer and DC volt meter and then put into Microsoft excel to create a generator voltage output curve vs. pedal speed Miles per hour MPH

Using a P90 in the Neck of a Tele, we show the volume change that the VVR will do. We start in this Trainwreck Liverpool clone with the voltage normal and the VVR off. Then you see that guy with the guitar turn down the voltage to about 1/4-1/3-ish voltage

Sketch can now be found at: gist.github.com Components used are: - Arduino Uno - Prototype Shield - BC417143 Bluetooth module - Generic brushed ESC - 1602 LCD Screen - HTC Inspire 4g running Android ICS The electronics were pretty straight forward. I was originally planning to build a electronic speed controller from scratch but after pricing all of the parts needed, it turned out to be A LOT cheaper just to buy one already made. Another problem I had to address was getting power to all of the electronics. The Arduino requires 5v but has a built in voltage regulator that can accept a source up to 12v. The servo needs 5v and the ESC can handle anything from 7.2v-9v. Aside from the different voltage requirements, powering the Arduino from the same source as the servo and ESC is bad practice as it could cause cross-talk interference. With that said, using 3 separate power supplies is not practical by any means either, so I would need the ESC and servo to be powered by the main battery pack and I could then use a separate 9v battery to power the Arduino. Now, in order to power the 5v servo from the 7.2v battery pack, I ended up using a LM7805 5v voltage regulator which is wired to the ESC and mounted on the bottom of the prototype shield. Now that the electronics were taken care of, the next step was programming the Arduino. For the most part, this was pretty straight forward as well. Interfacing the Bluetooth was really easy. The module I bought communicates via serial and ...

Super Car Utilizes an Arduino and is controlled via a Wireless Playstation2 Controller. Also controllable via Serial and TV Remote as demonstrated in my other videos: Video Dialog: The car's original remote is inside this Altoids Tin. This is the wireless receiver for the Playstation 2 gamepad. Here are the connections for the PS2 controller as well as the voltage divider for the battery gauge and other power wires. (This is the gear control switch, rigged for LOW currently.) The horn, digital potentiometer chips for the car remote and the voltage regulator for the car remote are here. The LCD screen displays 3 screens with current internal program values as well as the fuel gauge. A quick demonstration of how to control the car via the PS2 gamepad. Now for a drive! This car was designed with digital proportional drive controls and I have been able to replicate this control via the analog joysticks of the PS2 gamepad. Thanks for watching!

This is a very simple oscillator which uses a TS 2950 3.3V voltage regulator to light an led and charge batteries.It takes advantage of an unwanted characteristic of some voltage regulators which is oscillation or noise and i use this to pulse a coil.A more complicated setup with a 1:1 bifilar coil is also shown and this produces a higher voltage (even above supply voltage) than the voltage regulator supplies under normal operation.

Order the KZX1250 at www.adicorp.net The KZX1250 is a brand new PWM, not to be confused with any other PWM; The KZX1250 has an on board computer with advanced features that make it virtually bulletproof and safe to use, no other PWM can match it. Don't trust any PWM under your hood. With the KZX1250 you know you are safe and that your PWM is designed to handle tough situations that most other PWM's were never designed to. Start out with a computer that digitally generates the pulses. Send the output through Schmidt triggers to get a sharp squarewave which is then fed to a high speed MOSFET driver and finally to 8 PowerPak MOSFET's through their own individual driving resistors. The efficient design means it runs super cool. How cool is that? The KZX1250 does not have a heatsink because it just doesn't get very hot; just a small 40mm fan. With 50 amps going through it at max frequency, the KZX1250 enclosure doesn't even get warm and the protruding circuit board gets luke warm, you can squeeze it between your two fingers without getting burned! As you'll see in the video, the KZX1250 has short circuit protection. Automotive fuses can take up to 100 miliseconds after its rated current is reached before opening. That's a tenth of a second; which might seem fast to you, but to semiconductors, it is like a year! Fuses are activated by heat and the same heat that the fuse sees is the heat that the MOSFET's see as well. The KZX1250 opens the circuit in less than 1 millisecond so ...

aka Magnetometer-Barometer Board ;) This is just a little video of me populating the board that will be used in my UAV project. Hopefully, the magnetometer will make the orientation sensing work properly. The chips used are the HMC5883L 3-axis Compass (magnetometer), BMP085 Pressure Sensor (barometer), and the TC1015 LDO Voltage Regulator. I have already done a basic communication test and both chips are responding with acknowledgments so I guess I didn't fry them!

A simple useful implementation of the low powered toroid oscillators shown recently. 3x 1.8W solar panels are connected to a rejuvenated car battery (was completely dead, sat outside for a couple of years and a homemade Bedini wheel knocked the sulfation off). The battery connects to a LM317T circuit, which converts the power to a constant 1.2V. The circuit is within the datasheet.for the LM317T. Out then, to a 1200 turn approx 1" ferrite toroid, with approx 70 turns as the Primary. A 2SC2655 then supplies the switching to power the mains rated LED night light. The light can be left on 24 hours a day. It uses only 5mA. The best running brightness can be regulated with a pot on the LM317T circuit (20K). The 3 homemade battery cells run 'Penny' oscillators, see Lidmotor's channel for the circuit diagram for that circuit. Note - Zinc Oxide not magnesium oxide is used within the seashell cell. All 3 were stovetop type cells, see IBpointless2's channel for a video where he shows how to cook down the ingredients

**Always follow the instructions in your repair manual when doing repair or maintenance work on a motorcycle. Manuals can be found at the dealer and online.** To check the regulated charging voltage on a 2009 Kawasaki KLR 650, requires a voltmeter, ratchet, extension, and a 8mm and 10mm socket. The first step is to warm up the motorcycle to operating temperature. After the bike is warmed up, remove the side panels and seat to get access the the battery terminals. The battery must be in good condition and be fully charged and the battery terminals should be clean and making good contact with the battery. According to the Clymer manual a fully charged battery must measure 13 or more volts, but I think anything over 12.6 volts is fully charged. After determining that the battery is good and fully charged, run the motorcycle at 3000 rpm and turn the headlights on bright. Place the meter leads on the battery terminals and measure the voltage. You should get a voltage between 13.8 and 14.8 volts. If your measured voltage is out of range, than obtain a wiring schematic for the motorcycle. If the voltage reading was low, than check for a open or short circuit in the charging system wiring, and also check the alternator stator, and condition of the regulator/rectifier. If your reading was high, than check the condition of the regulator/rectifier, and check all connections related to the regulator/rectifier. A bad battery can also cause a bad reading, so its very important to make ...
