Then with the cool Soundcard Oscilloscope to which I could adapt my ll801b duration. His initial tests showed that the AC outlet and its remote could be revived, so he set about exploring its guts.

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.
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.
I think that code has a bug though as the logic low component of the syncbit should be 31 times the short-pulse duration according to the datasheet not 7. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. 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.
When I got mine to work I lp8001b using lp801n datasheet-correct count so I didn’t test with that. Note below on the jumper blocks: I put it in a small electrical box with 2 push-buttons and installed it in an easy to reach location from the bed. I popped the original remote open to see what I was dealing with. The board runs off a 23A 12 volt stack battery. The building’s basically a 1-room apartment so this works out great with the remote.
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.

It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.
So I took the code at http: I did find a puncture mark on the positive lead so that must have been it. So I wanted a second controller that would basically be llp801b stationary switch by my bed so I could leave the portable remote around the desk.
The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. At least 1 5.

It also analyzes transistor’s characteristics such as voltage and gain. Running from lower voltages may be possible but the RF circuit definitely needs to be retuned. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
It took several modifications to my original board to get it working with the attiny. The relay control from the decoder was routed via the microcontroller. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
Working on the AC outlet requires far more care and safety. Working on it when it l8p01b powered up requires extreme caution.
RF Remote Control Light Switch
The only light switch is across the room from my PC and it’s a pretty large room. He’s basically divided the datasheet units by 4 in case anyone actually looks into this The decoders may not care as It seems to have worked for him.
These remote AC outlets consist of an encoder chip on the remote and a corresponding decoder chip on the outlet, working at MHz. The transmit remote was a quick fix — changing the DIP switch selected address bits from being pulled low to high and swapping the On and Off buttons to make it compatible with the other outlets. 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.
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. The output waveforms can be both amplitude and frequency modulated. Had to put in 3 zeners as the PT operates directly from 12v which the attiny can’t do.
Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.
You can control lights, fans, AC system, computer, printer, 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. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. 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 around 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.
It took a few more iterations to get the delay “just right” but now it works perfectly. If I knew in advance that I’d be able to do this I would’ve designed a much smaller board.
