- Валерий Бабанин.. A homemade optocoupler (Figure 4) with a GL5506 photoresistor (peak spectral sensitivity is 540 nm) and a green SMD LED (510-555 nm) of 3014 footprint (3.0 mm × 1.4 mm) is used. Such a pair effectively performs its function at 100 ...
.. Yellow and white LEDs have been successfully tested. Don't forget to shade the optocoupler in bright light. Figure 4. Design of a homemade optocoupler. The filter capacitor C3 can be omitted when working with frequencies above 1 kHz; ...Nov 20, 2024
- .. is the 9 volt GS transmitter which does not use a crystal. This clever design allows only two transistors to generate both the ...Mar 8, 2005
- .. This circuit will power a 6 inch 4 Watt fluorescent tube off a 12 Volt supply, consuming 300 mA. It may also be powered by a suitably rated universal AC/DC adapter. Advantages of the ...Nov 5, 2008
- .. FET, which can turn on a beeper or activate a relay. If a low power voltage comparator is used, such as the LMC7211 , a 9 volt battery will power the circuit for many years. The more popular LM358 would also work but would draw more ...
.. David Johnson P.E. Challenge: Design a battery powered circuit, which can turn something on or off, with the wave of a hand over a surface. ...Mar 31, 2009 - .. at 325 RPM, making it excellent as an electricity generator. However, pretty much any permanent magnet motor with a good volt/RPM ratio will do. Keep in mind that if you want to generate useful electricity, you will need to produce at ...
.. (to measure angles for the hub) Sandpaper (various grits) Parts Required I wanted to be as minimal as possible with my design (I'm a poor college student), so I took the already simple designs from around the web and made them even ...Oct 19, 2009 - .. tape drives). The best apparently are a couple of models of motor made by Ametek. The best motor made by Ametek is a 99 volt DC motor that works great as a generator. Unfortunately, they are almost impossible to locate these days. There ...
.. out with complex issues, teach you electronics theory, help you locate parts, build a charge controller for you, or custom design a system for you. There just aren't enough hours in the day. Sorry. Update: Here is a video of the wind ...Oct 26, 2009 - .. temperature and pressure sensors as well as to monitor the battery voltage. To maximize accuracy I used an external 4.096 volt 0.1% reference from National Semiconductor. With the 10-bit A/D, this provides a resolution of 4mV per count. The ...
.. the airport or some other remote location. But, what are conditions like in my backyard? To address this, I embarked on the design of the Wireless Weather Station. I had meant to do this project many years ago but two bits of technology ...Dec 22, 2009 - .. a Savonius rotor. At 200 RPM the output is only about four or five volts. While this is obviously not enough to charge a 12 volt battery by itself, a bit of clever circuitry solved the problem. Some time back a circuit was published in one of ...
.. shaft! The rotor slides directly onto the end of the motor shaft, and is held in place with a stainless steel bolt. In this design, I decided to see if I could do away with having a top bearing. The bearings in the tape drive motor are at ...Nov 1, 2010 - .. off and there is absolutely no current drain from the battery. When the sun gets up and panel starts producing at least 10 Volt, the LED lights and the two smalltransistors switch on. This powers the regulator circuit. As long as the battery ...
.. one has to choose the most appropriate type of regulator. In most solar installations I have used my linear solar regulator design, which has the advantages of smooth voltage regulation and undervoltage load dumping, at the cost of higher ...Dec 5, 2010 - .. Figure 1. Dual-output hybrid SEPIC-Ćuk converter. To find out the output voltages we apply the principle of inductor volt-second balance and capacitor charge balance. To simplify the calculus, we neglect the voltage drop over the ...
.. EDN Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC-Ćuk converter whose positive output voltage can be lesser or ...Aug 10, 2017
