Modern television remote controls have a massive number of buttons compared to their more primitive predecessors, and because of this, seniors can struggle with knowing which button to press and when as well as having difficulties seeing the small text. This problem inspired Instructables user omerrv to create a device that he calls the Sababox, which contains just a few large, easily-pressable buttons for simple use.
The Sababox is equipped with an Arduino Nano at its core, which is connected to a grid of 14 momentary pushbutton switches. A separate circuit was also made from a Nano and IR receiver module that can read incoming infrared pulses from a remote and record them for later use. For instance, a volume up command contains a series of values which are then placed into the code for the Sababox’s Nano. When a user goes to press the larger “VOL +” button, that same command is relayed to the target device. One other nice feature of the Sababox is that it can be used to control more than one device, and omerrv currently has TV, radio, and air conditioner commands for his.
After the electronic circuit and programming had been completed, the whole assembly was placed into a large 3D-printed enclosure along with the necessary buttons and labels.
