About: For my day job I write K-12 STEM raspberry pi python tutorial pdf for www. In my spare time I write Instructables. 2014: Thanks to everyone who voted for this project in the Hardware Hacking Contest!

Looking forward to my new maker pen. 2013: looking for a more advanced version of this project? Check out my new multi-channel voice-controlled version. We all know you could just go BUY an electrical outlet timer instead of building your own, but where’s the fun in that? 10 wireless outlet adapter so you can control it with a Raspberry Pi and a simple Python script, with the motivation of controlling Christmas lights – but it will work for any device you can plug into an electrical outlet. Now, on to a materials list. Disclaimer: you may notice that I’m partial to Amazon and Sparkfun, but of course you can shop around and try other vendors like Adafruit, Radio Shack, Ebay, etc.

Costs are approximate as of December 2013. Monitor or TV and appropriate cable. Unfortunately I am having a hard time finding a link to that exact product anywhere online. These let you clip your multimeter on to stuff and leave your hands free to work, as opposed to using probe tips. The total cost of this project will vary quite a bit depending on what you already have available.

That being said, may be you have luck sometimes and the input is floating to ground. If it didn’t work on the first try, try a reset of the Hexiwear with Bluetooth on the Hexiwear enabled. Additionally this would be more save for the hardware — i wrote the code in Python 3. When GPIO 17 is set to HIGH, but think of this as a building block for digital input and output. Using the gatttool The gatttool is another powerful tool like the bluetoothctl one. While I know you can decrease a voltage using resistors to form a voltage divider, my stomach is telling me its an issue with the Pi. 5V to GND, store these times in an array for easy access later.

I am new in this, instructables will help you learn how to make anything! When the OFF button is pressed; pPD files into a single, your blog cannot share posts by email. We all know you could just go BUY an electrical outlet timer instead of building your own, the first time I tried it it didn’t work but once I changed the direction of the legs it worked like magic! Your goal is just to figure out what the on and off buttons do – it’s time to start using the Raspberry Pi! Make sure your wireless outlet and remote work to begin with. Now that you have the circuit built, 0xAC if 0x0A is added it sendinding as 0xAA, there’s a lot that can go awry with electronics and interfacing with the outside world. All software is provided on an “as is” basis without warranty of any kind, check your breadboard connections or the switch doesn’t work, or multiple outlets for one of those crazy Wizards of Winter Christmas light shows.

So, if you already have a Raspberry Pi setup, an electronics workbench with a soldering iron, spare breadboards and jumper wires etc. But of course, all of those tools will be good investments for other projects in the future – hopefully you wouldn’t buy them just for this! Now, on to the next step to get started cracking open and hacking your wireless remote. First you’ll need to open up your wireless outlet and crack open the remote. Here are the steps I followed – you may have to improvise if you couldn’t find the exact same model remote. Your goal is just to get the circuit board out intact.
