How to wire a GY6 scooter regulator / rectifier and how it all works (Part 2 battery connections)
0 comments Posted by shopping-team at 11:30 PMokay first we take a look at our battery, the fuse and how it's connected up, also we check the voltages and what you should be getting.

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

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.

Electronic measurement equipment and multimeters - Part 8: Oscilloscope
0 comments Posted by shopping-team at 9:45 PMIn this video I do a basic demonstration of the Hantek DSO-1200 oscilloscope as well as the Fluke 43b oscilloscope function. I demonstate some of the functionality and trouble shooting around my solar powered Kindle DX project. I talk a about supercapacitors and show a nornal capacitor working in conjuction with a voltage regulator. Details: www.kmeasure.co.za Digital Oscilloscope Specifications: . Dual Channel oscilloscope . 500 MSPS sampling rate . 200 MHz bandwidth scope . 8 bit resolution . Isolated ground Digital Multimeter Specifications: . Multimeter Testing modes: Voltage, Current, Resistance, Capacitance, Diode and Continuity . Max input voltage: 800 VDC & 600 VAC . Max input current: 10 A (AC&DC) . Max input impedance: 10 M? .

Charging light on and battery going flat? It might be as simple as this repair....new brushes and regulator, easy to fix and only £16 ...no need to remove the alternator either!
