Running from lower voltages may be possible but the RF circuit definitely needs to be retuned. You can control lights, fans, AC system, computer, dataeheet, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

It also analyzes transistor’s characteristics datasheet as voltage and gain. Then with the cool Soundcard Oscilloscope to which I could adapt my pulse duration.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. It is datawheet irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. After some wasted time I caved and connected the original remote’s encoder chip data output pin to the microphone input of my netbook.

Note lp80b1 on the jumper blocks: It took a few more iterations to get the delay “just right” but now it works perfectly. I was trying random numbers for the pulse duration and randomly tuning the white variable capacitor but with none of the parameters actually being correct this method was never going dataasheet work. When I got mine to work I was using the datasheet-correct count so I didn’t test with that.

If I knew in advance that I’d be able to do this I would’ve designed a much smaller board. The only light switch is across the room from my PC and it’s a pretty large room.

It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Dataeheet Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.


Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

It took several modifications to my original board to get it working with the attiny. So I wanted a second controller that would basically be a stationary switch by my bed so I could leave the portable remote around the desk.

The building’s basically a 1-room apartment so this works out great with the remote. I think that code has a bug though as the logic low component of the syncbit should be 31 times the datasheft duration according to the datasheet not 7.

After reseating the board in the box and making sure the battery wires don’t pass under any component legs it hasn’t happened again. I popped the original remote open to see what I was dealing with. Of course since I’m using the remote to cut the lights when I go to bed I’m basically using the remote from two places which brings with it the unavoidable annoyance of the remote being in the wrong place all the time. Has a few address and data pins and generates a signal on the output pin based on the configuration of those at the time the enable pin is connected to ground.

This is datashret remote controllable light switch that comes with an RF remote. He’s basically dstasheet the datasheet units by 4 in case anyone actually lp81b into this The decoders may not care as It seems to have worked for him.

It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. At first I didn’t think much of it and ordered some PTs and made a PCB which is basically a clone of the original remote adapted for components I had lying dstasheet or just stupidly large pads where I had no idea what I was going to use when I made the board Not being patient enough however I started looking around to see if anyone’s emulated this chip on a microcontroller before.


Which means I have to get up and look for it which is effectively as much of an annoyance as it was meant to solve. Turns out, several people did. At this point I tested my board and while tuning the variable cap it suddenly became dark in the room: Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may dataasheet supplied from a single 9V battery.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. I did find a puncture mark on the positive lead so that must have been it. So I took the code at http: The board runs off a 23A 12 volt stack battery.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Some component leg that I forgot to cut probably a resistor must have punctured the battery wire though as it drained to 10v by that night and since the circuit is basically open when none of the buttons are pressed that shouldn’t happen at all.

Had to put in 3 zeners as the PT operates directly from 12v which the attiny can’t do. The output waveforms can be both amplitude and frequency modulated. I put it in a small electrical box with 2 push-buttons and installed it in an easy to reach location from the bed.

The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. At least 1 5.
