Little Bedini motor and BIG solar panel running indoors with just ambient light and no batteries. Light energy is being controlled by a "step down adjustable voltage regulator" which allows energy to build up in a large capacitor before it feeds the motor. Energy coming off the collasping magnetic field of the motor drive coil is recycled back into the motor.

Please watch this in the highest quality, as it shows much better detail. This is just a preview of my on screen display project in progress. I will have a better video uploaded soon, I just wanted to show people it is not vaporware ... it really works. In this demo, text is drawn and a logo is blitted. All of this is dynamic; it's being drawn at approximately 20 frames per second. As the processor only has 3 MIPS or so of its 39.7 MIPS available for drawing graphics (read: the rest is dedicated to the TV output stage) I think this is very impressive. But look out for even greater performance increases in future versions where I implement a few additional speed ups. The glitch at the top is due to a bug in my OSD, which I hope to fix in the first release. It is just reading the memory before the video RAM and you are seeing the SFRs and line data. Nothing to really worry about. It is helpful as an indicator of frame rate. Super OSD is a free, open-source (GPLv2)** graphical on screen display for PAL and NTSC video signals. It is primarily designed as an alternative to current model aircraft OSDs, which are usually too limited, WAY too expensive, or closed source. It is based on a dsPIC33FJ128GP802. This device has 16K of RAM and 128K of FLASH. Almost 94% of the RAM is used but only about 17% flash is used, this includes the logos you see. An LM1881 is used to sync and a LM317T is used to generate a +3.37V supply for the 3.0-3.6 volt dsPIC. 256x192 pixels are drawn, and ...

Here in my first robot which has the ability to detect laser light or a particular coloured ball and can be calibrated to get attracted or repelled by it accordingly. It has light sensors (ldr nad led) a microcontroller , 7805 voltage regulator IC , L293D motor driver IC AND LM324 comparator IC. It is the simplest combination of the given IC'S and one of the most basic robots and is ideal to learn for anyone interested in learning embedded systems and VLSI design in robotics.

I did not do anything fancy as I just got it and am still playing with it before I do some serious 3D with it:) But anyway, I just landed turned it around and took off again in the video, sorry for the camera blurr, I don't really know why it didn't want to focus on the plane, so that is why I cut the video where I did (because the rest of it was even more out of focus). Like I said, this is me flying the Kat, and my dad took the video. I plan on posting more videos of this plane on youtube, and getting a better, closer up video of it, as well as some videos of me flying 3D with it! And PLEASE rate and comment!

with Eddie Beville, Design Manager - DC/DC uModule Regulators video.linear.com There is an alternative solution when deciding between a step-down switching regulator and a linear regulator. Switching regulators dissipate less heat than linear regulators especially when the input voltage is much higher than the output voltage or the output load current is relative high. On the other hand, linear regulators are very simple and dont require inductors. What if there was a switching regulator circuit could be simplified and fitted inside a surface mount package and the complete solution became as simple as a regulators circuit? No inductors, no MOSFETs, no difficult calculations for compensation circuitry. On paper, it is a simple square box with a few resistors and capacitors. On a PCB, it is also a simple square box with a few resistors and capacitors.

Picked up a M&S 20 inch TV from the garbage last week and since I was with a friend I lugged it home. It didn't turn on but I could hear the main relay clicking inside when I pushed the power button, so it was clear that there was standby voltage but no B+ This TV sports a very prehistoric power supply design, using a STR50103 linear voltage regulator with a honking power resistor in series in order to step down and regulate the incoming rectified and filtered line voltage. No transformer here. Turns out that a 470k 1/2 W resistor was open and the 130V protection diode was shorted and disconnected from the circuit, replacing the resistor got the TV working again but with a craptastic picture and the shaking you see in the video. The higher the brightness of the picture content, the stronger the shaking. Replacing a couple of electrolytic capacitors around the flyback area improved the picture considerably. As for the shakes, it turns out the regulator was defective, providing an excessive B+ of 125 V while the nominal value for this particular regulator is only 103 V. Needless to say, replacing the regulator got me a correct B+ and that stopped the shaking altogether. After adjusting the static convergence and the cathode levels I got a much improved picture, almost perfect from a TV that was salvaged from the scrap heap. I love electronic challenges like this one but I don't really need yet another TV set, so I gave this one to my mom after fixing it so that she can ...

All about what's inside AC Power Adapters. First I break them open, then I disassemble the components, and then I back engineer their electrical and electronic design. Learn to identify, test, and repair AC power adapters. They power your computer peripherals, cell phones, battery chargers, and gadgets? The purpose of wall transformers is to step-down residential AC voltage to a much lower voltage, typically between 3 and 36 volts. Some adapters have an AC voltage output while others have a DC voltage output. Find out if your ac adapter is good or bad.

Hi, My latest mod, working stable so far :-) I don't know why but I can get only x5.5 multiplier for PPC :-( I will fight with voltage regulator to get x6 multiplier working. By doing so I can get more than 400MHz CPU speed in Classic Amiga :-) RAM is VERY critical here, must be really good. Pictures: picasaweb.google.com I must put clean install to get reliable benchmarks ;-) Now it's complete mess; sorry, my fault ;-)

Kohler 10 HP driving a eBay 7.5 KW 4-pole generator. The engine is set at 3400 RPM max torque curve, generator is running 1800 RPM for 60 HZ. A homemade voltage regulator is installed not shown. The generator does pretty well, so does the engine. It looks like we are able to get about 5000 watts, stable. At 7500 watts, the voltage falls too low and the frequency falls to 42 HZ. At 10 KW the engine is totally overloaded. 5KW is respectable. Generator has about 50 hours on it and seems to be holding up okay.

Ford 400 - Part 2

My Ford Bronco Ranger XLT with Ford 400 engine in it. I've since pulled this engine and replaced it with a moderately built Ford 460. This 400 has an Edelbrock Streetmaster 400 intake manifold, Holley 4 barrel 650 CFM carb, full-length headers, dual 3" exhaust, and an otherwise stock engine / drivetrain. Stock ignition, distributor, C6 automatic transmission, NP 205 transfer case, heads, cam, etc (As far as I know). This video is part 2 of 2 - see part 1 for a shorter video of just the engine running - no electric radiator fan noise.Note: this video was created primarily for myself as a comparison between engines (Before and after the swap - I'll post the new engine videos as soon as I can). Also: if anyone is interested in purchasing this engine (Minus headers, ignition, A/C, P/S. Intake, carb, alternator, voltage regulator all go with engine), please send me a message! Yes, the engine rattles at certain RPMs - I think the main bearings are shot. Engine runs fine otherwise - no oil leaks and doesn't burn oil.

DMX 12-24v Lighting Controller with manual control mounted in a military case with bulkhead or chasy mount style connectors. Manual control circut switch is intigrated into the "pluging it in" so theres no switch to break. You plug it in it powers the voltage regulator on to give proper voltage to go through the pot and then returned for the analogue control. This is just a prototype there will be future revisions such as making it better looking inside mabe even multiple units in a larger housing weel see where it goes.
