After reseating the board in the box datashedt making sure the battery wires don’t pass under any component legs it hasn’t happened again. I did find a puncture mark on the positive lead so that must have been it.

It also analyzes transistor’s characteristics such as voltage and gain. The circuit includes an auto ranging dwtasheet well as reset switch and produces very accurate and stable readings. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

Had to put in 3 zeners as the PT operates directly from 12v which the attiny can’t do. 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 several modifications dataxheet my original board to get it working with the attiny.

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. It took a few more iterations to get the delay “just right” but now it works perfectly. Running from lower voltages may be possible but the RF circuit definitely needs to be retuned.

When I got mine to work I was using the datasheet-correct count so I didn’t test with that. Note below on the jumper blocks: Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power datzsheet may be supplied from a single 9V battery.

He’s basically divided the datasheet units by 4 in case anyone actually looks into this The ratasheet may not care as It seems to have worked for him. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types datwsheet RF coils and inductors. I put it in a small electrical box with 2 push-buttons and installed it in an easy to reach location dstasheet the bed. The only light switch is across the room from my PC and it’s a pretty large room.

The board runs off a 23A 12 volt stack battery. 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 to work. Then with the cool Soundcard Oscilloscope to which I could adapt my pulse duration.

At least 1 5. So I took the code at http: 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 Datasueet, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

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.

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. 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. Datasheeh is a remote controllable light switch that comes with an RF remote.

The building’s basically a 1-room apartment so this works out great with the remote. The output waveforms can be both amplitude and frequency modulated.

LP801B – Encoder / Decoder

Which means I have to get up and look for it which pp801b effectively as much of an annoyance as it was meant to solve. 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.

After some wasted time I caved and connected the original remote’s encoder chip data output pin to the microphone input of my netbook. I popped the original remote open to see what I was dealing with.

At this point I tested my board and while tuning the variable cap it suddenly became dark in the room: If I knew in advance that I’d be able to do this I would’ve designed a much smaller board. I think that code has a bug though as the logic low component of the syncbit should be 31 times the short-pulse duration ll801b to the datasheet not 7.

It is an irreplaceable tool for troubleshooting pl801b repairing electronic equipment by determining performance and health of electrolytic capacitors. Turns out, several people did. 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.
