The heart of the LED chaser is the PIC 16F628A microcontroller, IC2. The program that runs on this chip controls the LEDs attached to the output port pins. Resistors R1 thru R8 limit the current through LED1 - LED8 to a safe level that won't damage the PICs I/O ports or LEDs. Resistor R9 provides a pull-up for the input connected to switch S1. R10 holds the PICs MCLR reset signal high. Capacitor C1 is used to decouple the 5 volt power supply to the PIC. The voltage regulator used is a LM2931-5.0, low-drop-out regulator and will maintain regulation with an input voltage down to 6 volts. Input voltage for the LED chaser should be between 6 volts and 14 volts to ensure power dissipation remains within limits. The LM2931-5.0 regulator is designed for battery powered and automotive applications and includes internal current limiting, thermal shutdown, as well as reverse battery connection without damage to itself or the circuit behind it. Capacitor C3 is important and must be fitted to prevent instability of the regulator output. i got this from: picprojects.biz

This is more work with Jonny Davro's "Voltage Regulator Oscillator". I show it here running a spinning magnet on a mirror.

I bought this cb750 in a bunch of parts in 6 different boxes. Slowly putting together something i never took a part is what i have come to in the videos. It is about 2 months of building at this moment. I used a few different parts from different cars like the ignition coil from a dodge stratus, and an Su Carb off a British MG car. I had to weld up a new intake manifold for the carb. The wiring harness was destroyed after i got done putting the bike together, so I built my own on this bike.

I built a wireless USB tether out of a battery grip, check it out! I used one half of a Cables Unlimited USB-WR2000 kit, a switching 5V 1A voltage regulator, all powered by the batteries inserted in the battery grip. All sewn together so I can run iPad based DSLR remote trigger solutions.

This video continues from a previous video on setting up a simple battery power supply on a breadboard. This video uses a mains transformer 9V Power Supply Unit (PSU) that allows us to power circuits without the need of a battery. However, the supply is noisy and could lead to difficulties. A diode is added to protect the circuit from reverse connections. A switch is added to simplify usage. A PTC (Positive Temperature Coefficient) Transducer is added to protect the circuit from short connections and Capacitors are added to smooth the supply. We use the oscilloscope to examine the quality of the output supply.

Homemade: A simple tester for Electronic Air Pressure Valves. Easy to make with a few components like: 1 LM317T (to get +10V) 1 Potmeter 10K (to regulate 0-10V to the input of the airvalve) 5 Resistors 3 Leds All the written on the front is just a remembrance of how to adjust this particular valve, and what the alarm codes are. For people that want to make this: Setup a LM317T circuit with an output of 10V. Connect the wiper of the potmeter with pin 2 (Left of notch) of the valve. The remaining 2 contact of the potmeter; 1 to mass and 1 to 10V (output 317T) Other pins of valve socket: Pin 1 +24Vdc-----( Right of notch) Pin 3 Mass--------(Left under notch) Pin 4 Analog output (Right under notch) connect a led with resistor Pin 5 Digital output (Center) connect a led with resistor

This is a DIY solar powered USB charger with schematic that you can build to charge your ipod, blackberry, iphone, camera, or any other electronic device that you can plug into a USB port. There are 2 (in quantity) 5 volt solar panels connected in parallel to a 12000 uF capacitor. The positive is then connected to pin 1 of the voltage regulator (low dropout), pin 2 connected to ground. Pin 3 and ground are then connected in parallel with a 470uF cap, which is then connected to the USB port.

I thought it might be helpful to see how the Relay installs on the TM Series markers. The v1 TM-7 has an Air Transfer Tube that adds some complexity/problems to the install, so you might consider purchasing the latest version when you buy the Relay. The TM-15 is a much easier installation following the included instructions.

My k2 1000 blew a fuse so I took a look at it...every new fuse I put would instantly be destroyed and some smoke would come out. To isolate the problem, I hooked the power brick straight up to another battery. Good ol smokey. SMOKE AT :18

Here is a Losi Micro SCT modified for 3S operation. a 7805 voltage regulator was added on the switch terminal to trick the esc board of a continuous 5V supply thus disabling the over voltage cut off. Only the FETs and the voltage regulator is directly connected to the battery thus allowing full 3S operation on the motor and the usual 5V operation on the micro controller, AM receiver and the servo. The above video shows board power-up using multiple batteries - Stock NimH, 2S lipo, and 3S Lipo
