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

Liverpool VVR Test

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

Afroman goes over some basic information about capacitors: Capacitance, voltage ratings and polarity. Once you know what you are doing, you can replace faulty caps on your circuit board and bring your electronics back to life! Don't forget to vote! Panasonic FM series capacitors are usually a good choice.

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 ...
