TV-B-Gone Universal TV Power Remote Control Keychain

Product Information

Most TVs will turn on or off within a few seconds. But it may take up to 69 seconds for your TV-B-Gone® to reach the POWER code for your TV in its extensive database. We organized the codes to put the most popular ones first. http://www.mouser.com/search/ProductDetail.aspx?R=30310-6002HBvirtualkey51750000virtualkey517-30310-6002

For a TVb-Gone I can imagine one wants more range as the TV in question might be further away or behind glass or whatever. In v1.1 kits two pins on the microcontroller each control two transistors each (4 total) - this increased the base current to give better range. Because watching TV takes time, and time is precious. There are so many things to do that are fun, healthy, relaxing, and good for your social life! Some people find themselves watching TV when they don’t really want to. Have you ever found yourself doing this? Next I wrap the MOSFET gate drain and source with some heat shrink and then use a big piece to cover the entire MOSFET. The MOSFET then gets wired into the Arduino and connects the power source to the LED.http://www.mouser.com/search/ProductDetail.aspx?R=1-390261-2virtualkey57100000virtualkey571-1-390261-2 Next up is [Benjamin Kenobi] with TV Remote Control, Limited. Not everyone can operate the tiny buttons on a modern remote. [Benjamin] built this device for Easton, a special kid with a disability that impairs his motor skills. The 3D printed case holds two buttons – one for power, and one to change the channel. An Arduino Nano running [Ken Shirriff’s] IR library is the brains of the operation. The IR signal timing is hard coded for simplicity. One problem [Ben] ran into was the Nano’s high current draw, even in sleep mode. Batteries wouldn’t last a week. A simple diode circuit with a reed relay keeps the Nano shut down until Easton presses a button. I’ve created a schematic and added it to this project as well. All there is to it is a mosfet attached to an arduino, driving an LED. The dc voltage booster just steps the voltage up from 3.7v to the 5v that the arduino and LED needs. Mitch Altman http://www.pbs.org/mediashift/2006/04/digging_deepertvbgone_device_s.html (inventor of the TV-B-Gone) and his company Cornfield Electronics http://www.cornfieldelectronics.com/ worked together with me (Adafruit Industries) to develop a kit version of the TV-B-Gone. Mitch thinks open source kits are awesome!

How much of the TV that you watch do you really like a lot? If you could choose whatever it is that you’d like to be doing right now, anything at all, what would it be? Was your answer, “Watch TV!”? Whatever your answer was, my wish for you is that you have time in your life to do it. Please make time in your life for what you really like. Better yet, please make time to do what you love. Wouldn’t that be great? Don’t know what you love? Try out a few things, and see what happens. What would concern me is that for whatever reason the transistor (and thus the diode) might be switched on continuously for even a short while by e.g. a hanging program or testing.v1.3 - Semver versioning implemented; various code updates, clarifications, & comment additions, and changes to fix PROGMEM incompatibilities so it will now compile with latest versions of gcc compiler; also improved blink indicator routines & added the ability to stop the code-sending sequence once it has begun; by Gabriel Staples ( http://www.ElectricRCAircraftGuy.com) Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane]. TV-B-Gone remote controls mimic all of these different ways that manufacturers have of pulsing IR light. And it does it in the same way that almost all other remote controls do it: by a small computer chip sending out the correctly timed pulses from information stored in its own database to the IR LED. But unlike most universal remote controls, TV-B-Gone only emits pulses for POWER, which, of course, is the only important function of any remote control, since this will put televisions in their most beneficial state: OFF. Another difference between TV-B-Gone and most other universal remote controls is that it sends out its code for virtually every manufacturer of televisions. Since tv manufacturers often use different POWER codes for their North American televisions than for their European televisions, we make 2 different models of TV-B-Gone universal remote controls, one with a database of North American POWER codes, and one with a database of European POWER codes. The POWER codes for most Asian televisions are almost all the same as those for North American televisions, so the North American model is also the same as the Asian model. The PROGMEM tells the compiler to store it in ROM. This is important because there is only 512 bytes of RAM but 8192 bytes of ROM (flash). By default the compiler thinks we want to store stuff in RAM because we can then change it easily. ROM cannot be modified by the chip itself easily.

From our research, we found we could put in two 2032 batteries instead (one in the B1 position and one in the B2 position), which are bigger, longer-lasting, and almost the same price. So we will be putting these in the new models and recommend it when replacing the batteries in all TV-B-Gone models.You can measure the frequency of the IR pulses. As you can tell by the cursors and the measurements on the side, the frequency is about 37.04KHz Whenwe were putting together the TV-B-Gone kit,we started imagining a dystopian future, filled with televisions, where this kit would be super useful and we'd be a hero for having one. And while maybe that's dramatic, the TV-B-Gone is perfectfor playing pranks on your friends during the Super Bowl or getting some peace and quiet during dinner. There are three main video formats currently in use: NTSC, PAL, and SECAM. If your country uses NTSC video, then the North American/Asian model should work. If your country uses PAL or SECAM video, then the European model should work. The TV-B-Gone is a kit that, when soldered together, allows you to turn off almost any television within 150 feet or more. It works on over 230 total power codes - 115 American/Asian and another 115 European codes. You can select which zone you want during kit assembly.
