The Starter Kit: Hardware Hacking is currently not sold due to the unavailabilty of simple remote control mains switches.
The Starter Kit: Hardware Hacking is about hacking low voltage mainstream devices to connect them with Tinkerforge modules. Any (Embedded-) PC, Smart Phone or Tablet can be used to interact with devices hacked by this kit. Interaction is possible over USB or via Wi-Fi if a WIFI Extension is added. Also a direct Ethernet interface with the Ethernet Extension can be achieved.
Two remote control mains switches are included in this kit, so you can directly start to hack something. A step-by-step guide will tell you how to do it (soldering iron, solder and a screwdriver are required).
There are two groups of applications of this kit: controlling and reading out. For control applications an Industrial Quad Relay Bricklet is included. It contains four on/off switches. For read-out applications an Industrial Digital In 4 Bricklet is included. It can read out four digital galvanically isolated signals with voltages up to 36V.
Documented example applications are:
Many more applications are possible, anything that is controlled by a remote control or output digital signals is easily hackable by this Kit. The given examples applications should be enough to give you the power to hack any electronic appliance in this category.
A how-to video that shows how to hack the mains switches and some applications can be found on Youtube:
|Digital Input Low Level Voltage||0-2V|
|Digital Input High Level Voltage||3-36V|
|Maximum Switching Current||1.2A per switch|
|Maximum Switching Voltage||30V per switch|
As a very first step you should try out and update your Bricks and Bricklets.
For that you need to install the Brick Daemon and the Brick Viewer. Connect all Bricklets to the Master Brick and connect it via USB to your PC. Afterwards use Brick Viewer to find out if all of the firmwares are up to date (Updates / Flashing button). If not, you can update the Bricks and update the Bricklets with the Brick Viewer, too:
As next step click through the tabs of the Brick Viewer to see if the Bricklets are working correctly. Now you can be sure that the Bricks and Bricklets have versions that work together.
Basically there are two different options with this kit: Detect digital signals and short-circuit signals. A detailed description of the basics can be found in the Hardware Hacking for Beginners tutorial.
Keep voltages in mentioned limitations and don't hack devices which are supplied by dangerous high voltages (e.g. mains voltage)!
If you want to read out the state of an electronic device, often there is a voltage source somewhere that represents this state. If it is a digital signal and the voltage is below 36V, you can connect the Industrial Digital In 4 Bricklet to it and read it out. A good option are LEDs. If your device has an LED representing a state you can easily read the state.
It is important to keep in mind that a high signal level is detected starting at 3V and a low signal level is detected below 2V. In between the behavior is undefined.
To read out a signal, connect it to one of the input ports of the Industrial Digital In 4 Bricklet. If you don't see any reaction of the input port in the Brick Viewer you likely have to reverse the polarity of the input. You can find the correct polarity by trial and error, the Bricklet is protected against reversed polarity.
Below you can find a connection diagram that shows a possible setup if you want to detect the state of an LED. The series resistor is included to obtain suffice levels for high/low detection.
With the Industrial Quad Relay Bricklet you can switch (short circuit) signals. Many devices have switches or push buttons that can be hacked with this the Bricklet. Remote controls are good examples.
Below you can find a connection diagram that shows a possible setup if you want to operate a switch with the Industrial Quad Relay Bricklet.
To connect the Industrial Digital In 4 or the Industrial Quad Relay Bricklet to a device you have to accomplish two things:
If you have never done this, take a look at the Hardware Hacking for Beginners tutorial for an in-depth guide that explains both steps.
There are many low voltage appliances that can be hacked. Here are some examples:
This kit includes two remote control mains switches that can be used as a first step towards home automation. We are going to hack the remote control of these switches and connect it to a PC to create software controlled remote switches.
We connect an Industrial Quad Relay Bricklet to the buttons of the remote control. There are a vast number of remote switches available on the market. Most of the commercially available remote controls use the HX2262 IC with the same hardware design as the ELRO remote control. So this guide can be applied to most remote switches.
The full description of the hardware setup can be found here.
An example implementation of a GUI (compatible to Windows (.NET), Linux (Mono) and macOS (Mono)) is available in C#.
Minimalistic examples are available in:
Wirelessly interconnectable smoke detectors allow to read out the alarm signal of a whole smoke detector network at a single point. We are going to hack such a smoke detector and utilized this feature to trigger actions if smoke is detected. For example, notify someone with an email or a text message about the alarm.
For this project we use the wireless smoke detector set and connect an Industrial Digital In 4 to one of its LEDs that light up during an alarm.

Example implementations with step-by-step instructions are available for:
Garage door openers are quite useful. Typically they come with a remote control and we are going to hack one. After the hack your smart phone can control the garage door and you don't need to carry around the original remote control anymore.
A small description of the hardware setup can be found here.
In this project one port of the Industrial Digital In 4 Bricklet is connected to a typical 12V driven doorbell. A Python script prints "Ring Ring Ring!" if someone actuates the doorbell. You can extend this project such that it will send an SMS or let your phone ring if someone is at your door. Be creative!

An example application is available in Python.
