Why buy a UL Listed iDevices Switch when you can potentially electrocute yourself or start a fire with a self built alternative instead?
Here’s how!
First, you must install HomeBridge on a Raspberry Pi, and configure it as a HomeKit bridge device. Instructions below.
Once you have HomeKit / HomeBridge working on your Pi and your iPhone, we can build a wireless power switch that can be controlled by Siri and the HomeKit app.
We start with a PowerTail2, and use the ESP8266 to control the on/off line.
We power the ESP8266 with a AMS1117 3.3V Power Supply Module. This brings the 5v from the charger down to the proper 3.3v that the ESP8266 needs.
We provide the power with a used cell phone charger. 110v -> 5v. This is wired directly to the ‘Line’ side of the PowerTail2 circuit board. It is always ‘Live’ or ‘Hot’ and will shock you.
We Load the code into the ESP8266 via your favorite USB/Serial converter (FTDI).
We plug it in. Homekit sees the device via the HomeBridge configuration file addition (accessory) on the Raspberry Pi.
You control the device on your iPhone, and turn electricity on and off at will.
Step 3: ESP8266 Arduino Code
/* * This sketch demonstrates how to set up a simple HTTP-like server.
* The server will set a GPIO pin depending on the request
* http://server_ip/gpio/0 will set the GPIO0 low,
* http://server_ip/gpio/1 will set the GPIO0 high
* server_ip is the IP address of the ESP8266 module, will be
* printed to Serial when the module is connected.
*/
// Start the server
server.begin();
//Serial.println("Server started");
// Print the IP address
//Serial.println(WiFi.localIP());
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
//Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String req = client.readStringUntil('\r');
//Serial.println(req);
client.flush();
// Match the request
int val;
if (req.indexOf("/gpio/0") != -1)
val = 0;
else if (req.indexOf("/gpio/1") != -1)
val = 1;
else {
//Serial.println("invalid request");
client.stop();
return;
}
// Set GPIO0 according to the request
digitalWrite(0, val);
digitalWrite(LED_BUILTIN, val); // Turn the LED on (Note that LOW is the voltage level
client.flush();
// Prepare the response
String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n\r\n
\r\nGPIO is now ";
s += (val)?"high":"low";
s += "
\n";
// Send the response to the client
client.print(s);
delay(10);
//Serial.println("Client disonnected");
// The client will actually be disconnected
// when the function returns and 'client' object is detroyed

EvilRuxpin – The Chippy Ruxpin Alternative – Hacking a Teddy Ruxpin with Next Thing Co. C.H.I.P $9 Linux Computer to Play Heavy Metal
So, I modified a Chippy Ruxpin into a more ‘evil’ form as a gift for a coworker.
1. Build a Chippy Ruxpin out of a C.H.I.P. and an old Teddy Ruxpin
2. Make it evil. Make it say random evil scary things every few minutes, and make the eyes glow red with an LED
3. Make it wifi. It is now ad-hoc so no keyboard is needed. Smartphone controllable!
4. Add DHCP server, so your smartphone can connect and pull an IP, so you can load the web gui over wifi
5. Add an 3W stereo audio amplifier. Stock ruxpin speaker + CHIP audio is kinda wimpy. DC 5V PAM8403 Audio Stereo Amplifier Board Volume Control Class D Kit Module
6. Add a big battery, maybe a 5w solar panel to charge the battery.
7. put a heavy metal t shirt on Teddy.
8. option to play stored heavy metal .mp3’s using mplayer in linux, controllable on the webgui page from a smartphone.
I chose Blackened by Metallica as the first Heavy Metal song played thru a Teddy Ruxpin ever in the history of the Earth. Yes my Teddy Ruxpin plays Metallica in stereo on command via wifi from my smartphone.
Dont’ forget to put an .mp3 file in /home/chip/Desktop/m.mp3. Obviously we are going to change this to play many many metal .mp3’s. ‘Cause that’s rad. Teddy Ruxpin Metal Beats Pill. If only I could figure out how to make the mouth/eyes move while mplayer plays an .mp3…………hmmmmmmmmmmmmmm
9. do it all as a boot script so no user input is needed after power on.
I’ve done it! (except the LED/GPIO part)
More to come! to do:
to do: integrate amazon echo hack, so that replys move the mouth and eyes of Ruxpin.
So, here are the basic steps (updates to come):
–flash CHIP with 4.3 headless. 4.4 wifi? doesn’t seem to work even if you modify the GPIO variables in the .py script.
–enable a wifi connection, apt-get update and apt-get upgrade
–install all the chippy crap from the link below
-get chippy working
–apt-get install isc-dhcp-server, again see link below
–apt-get install bc , this lets ./battery.sh work, so you can monitory your LiPo 3.7v battery from linux
–apt install wireless-tools(this step may break your normal wifi managed mode connection setup. its ad-hoc w no internet from here out, so if you want to install more software from the internet, do it before this step)
edit /etc/NetworkManager/NetworkManager.conf: wired device not managed
Most probably your interface appears in /etc/network/interfaces. By default, NetworkManager does not manage interfaces that appear in /etc/network/interfaces. You can change this behaviour.
To do this – in a terminal:
sudo nano /etc/NetworkManager/NetworkManager.conf
change the line managed=false to managed=true
Save, stop and start network manager:
sudo service network-manager restart
-configure that bitch /etc/dhcp/dhcp.conf
-configure /etc/network something/ interfaces to use 192.168.1.66 ip and dns, see links below
-configure wlan0 to always use 192.168.1.66 because we are evil
-config wlan0 as ad-hoc wifi on channel 6 see just below this
-config /etc/rc.local to do all this crap at boot, no login needed to turn on wifi and dhcp, and python script
edit /etc/network/interfaces make the ip 192.168.1.66 cause we are evil:
source-directory /etc/network/interfaces.d
auto wlan0
iface wlan0 inet static
address 192.168.1.66
netmask 255.255.255.0
gateway 192.168.1.1
edit /etc/rc.local code:
iwconfig wlan0 mode ad-hoc channel 6 essid “EvilRuxpin”
ifconfig wlan0 up 192.168.1.66
sudo service isc-dhcp-server start
cd ChippyRuxpin cause i installed under root
python /root/ChippyRuxpin/chippyRuxpin.py
after a editing /etc/rc.local, /etc/network/interfaces and /etc/dhcp/dhcp.conf, reboot.
once booted up, you should be able to connect to ad-hoc wifi “EvilRuxpin”
it should serve up a DHCP address between 192.168.1.10-20.
goto http://192.168.1.66:8080 or 80
page should load
note: my stupid dell laptop would not connect to the ad-hoc wifi, but my iphone 5s would.

The original code is for an Arduino YUN. The YUNs have built in ethernet and some code had to be changed to get it to work with my standard Uno with an ethernet shield.
Basically i had to strip out the Console.print and the Bridge.h commands, changing them to Serial.print . Also ,I had to shift the response string lookup digits a few places, because it was offset with the original YUN code. I just copied the RESPONSE from the serial monitor into Notepad, and counted the digits by using the right arrow key, taking note to count the spaces as well.
Here is the modified code that works on an Arduino Uno with an Ethernet shield. Dont forget to get your TembooAccount.h file from the temboo site.
Also, I had issues with the header code box not populating correctly while following the instructions. Try hitting refresh, switch between Arduino YUN and Arduino code using the box at the top of the temboo website.
You will need to edit the code below to include YOUR twilio auth code and ID. This code will turn a LED on digital pin7 if you send a text as “lights on” and turn the led off if you send “lights off”

I decided to keep the J1 resistor and C114 capacitor as they orignally were after reading some comments suggesting the signal strength would be better leaving them alone.
Step 3. Solder on Antenna Pigtail Cable. My cable was scavenged from a broken cheapie $5 USB Wifi adapter. The soldering was hard. It is just really small down there. Here is a trick: put a blob of solder on the tip of your hot iron. Now smear that melted blob OFF onto a dry sponge. Now you should be able to PICK UP a SMALLER BLOB of solder and place it where you want.
I used tape to hold down the wire. As you bend the cable, it puts a lot of tension on the two little solder points. If you do not hold down the wire somehow, your precious little solders will eventually break off. Since the tape will eventually fail, it would be far better to hold the wire down with a blob of hot glue gun stuff.
Step 4. Insulate, Assemble and Test.Make sure you insulate the two little R82 resistors under the antenna fitting metal. You do not want to short out the circuit board with the metal from the antenna screw fitting inside the case. A small piece of sturdy electrical tape under the brass nut should cover and protect R82.
This updated code removes the switch seen in the video and makes the motor spin automatically about .5 degrees every second. Here is the beta Arduino code sketch:
#include <SoftwareSerial.h>

I’m building the circuit now. Got the Teensy micro controller for the prjc store. The capacitors and resistors I got off eBay for less than $5 delivered. I will note that I should have bought a half sized breadboard, this one won’t fit in the USB hub case I’m going to use to encase the 3dpVert circuit.
