This is demonstration video of homemade red laser. It uses high power LOC diode, LPC-815. I'm using an LM317T driver to supply 410ma to diode and delivering about 200-250mw (or more, don't know) with acrylic lens in axiz module. This laser cuts, melts, burns and more. And beam is great !!!

This video explains how to build a simple regulated power supply for a digital camera. It can be built to run on 120/110Vac or 220/240Vac. The voltage for the camera being used is 3.15-3.25VDC using the LM317 voltage regulator. Voltage calculator link: www.cpemma.co.uk

Marine Diesel....with starter-generator. This Starter-Generator Combo unit is very simuliar to a golf-cart starter-generator. It's a Bosch Unit very much`like the ones used on early Harley-Davidson Gas powered 3 wheel golf carts. It came to me a mess. All the wires were twisted inside from miss handling of the main terminal. I restored the unit to like new condition and adapted a New Delco 12 volt Regulator to control it. A Ford Starter Relay works the "Start" side of the circuit. (Thats the bigger Red wire running behind the unit. This is a great addition to any small engine up to 20 hp not equipped with a starter or charging system. This little diesel has`a compression release to allow you to 'spin' the motor and use the heavy flywheel as help in starting an engine with 450-500 lbs compression as a diesel has. I can design these systems. Shop at 535 W Broadway Myrtle Beach SC 29577 843-455-8062

This is the standard Ramsey TFM3 Tri-Field Meter, with my own custom additions to it. First is an LM317 voltage regulator circuit - I misspoke in the video - in fact it now runs on 9Volts (6 AAA batteries) regulated to about 5.5 Volts for proper power esp. in RF mode which tended to drain the battery too low. Next is an extending 1/4 wave antenna such as found commonly in an AM/FM radio - this was to enhance the RF pickup - which is broadband - as such it now picks up even footsteps across a rug, or you petting your dog or cat, and picks up my FM radio transmitter with no problem at all (which was an issue for some people I noted). And last I added a two-transistor sound generator circuit connected to ground and to resistor R30 which is the common input to the LM3914 IC chip in the unit. This video shows it picking up RF easily (probably my wireless network) and also an example of it picking up some RF when petting the cat. (Electrostatic action gives off RF.) Also shows the Electrostatic still works fine, and though I did not show it here, the Magnetic works fine too. Voltage Regulator: ( www.national.com ) Sound: ( www.instructables.com )

Police Siren Emulation. 12vdc input from battery, that's fed into a 555 timer which makes the BLUE LED Blink, I then have a 1k resistor from the output into the transistor which inverts the signal to switch the RED led on. I have a 2nd feed into an lm317t which knocks the voltage down to 2volts which gets fed into a CMOS Oscillator which is then boosted by a transistor which gets fed to the speaker to ground. End result is this...

Using an audio transformer to boost up the audio signal and using a laser diode to transmit audio signal to a solar cell. The laser diode has it's own voltage regulator built from LM317. Audio signal originally change in term of voltage( and frequency) becomes changing in term of current( and frequency) before entering the laser diode. Current is propotional to the laser beam intensity. Subsequently, the solar cell reveicer the laser beam with a varying intensity( and frequency) and produce a audio signal change in term of voltage( and frequency). This improved version has a adjustable pre-amp which amplifier the audio signal before it reach the speaker. Using a low power Op amp LM324 instead of LM741 which only need a power supply of minimum 4VDC only. The improved version has enough power to drive a large variety of headphones and speakers wihout addition power needed. Pre-amp: Ultilizing a non-inverting amplifier configuration to prevent loading effect.

Information On Building This at www.h2o2fromh2o.oregonsouth.com Update 1/212/2009: The Plans are ready come and check them out. This is the first DIY project to the h2o2fromh2o website. A Simple Voltage regulator. Based on the LM317. Great for the bench to power projects while still on a bread board. Use as a bench Variable power supply. Have more then one to power your voltage hungry prototype 5V, 3.3V, 2.5V and so on. Use it on the production line to power your device under test, That's what I made the powerstick for. Vary cost efective when you need 10 power supplies and many diferent voltages. Photos avalible for V1.1.1 www.h2o2fromh2o.oregonsouth.com

Here is video of Adjustable Regulator using LM317(3-Terminal Adjustable Regulator).The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range.Here is very simple circuit having Two Capacitors , One Register Pot and LM317.The value of Pot is chosen so that my output voltage vary between 0V to 0.55V (DC).

High copper prices have a great impact on power cable prices, especially for larger sized cables having long runs. Prices have sky-rocketed over the last few years and it is with this in mind that Ashley-Edison developed a product to "compensate" for the problem.

Many owners, developers and contractors have to suffer this expensive problem, but by incorporating a "Constant Voltage Compensator" an installation cost may be drastically reduced.

When the voltage across a cable drops to a low value, the "Compensator" is able to detect this and compensate by boosting the voltage to a preset value - of say 400V. Using an "output sensor" it will continuously monitor the output voltage, which is checked against a "comparator", and if there is any shortfall it will instruct the transformer to add (+) or "boost" the voltage to its required value by means of a servo motor. In this way, the output voltage is continuously monitored and maintained.

This system does not emit any harmonics and has been a well proven voltage stabiliser design, in use for many years.

The "Compensator" is very suitable for use on Golf Course Lighting/Equipment, Perimeter Lighting applications and Farm/Estate Buildings etc. where long cable runs are an issue.

Both Indoor and Outdoor enclosure types are available to suit a variety of needs.

Alternative "Booster Transformers" have a main disadvantage as their output voltage is "following". This means that whatever the input voltage, the "transformed step-up" output voltage will not remain constant - fluctuating according to any load changes which will transmit to the load where it may be too high or too low. The voltage from no-load to full-load will cause the voltage drop to change drastically, which will not help improve the voltage drop. The "less than 4% volt drop window" is still not fulfilled and it is required to use a larger than necessary cable size. In fact, this does not help resolve the problem of expensive cables!
