The sonic hardware kit is designed to be sewn into clothing, accessories or interior objects such as cushions as a way to trigger sound.
Audio can be uploaded by removing the micro SD card and inserting it into the pc and copying over an mp3 file. No naming convention required except use of .mp3 extension.
The battery is charged via the USB port on the circuit. Keep the battery connected to the device when charging and the power switched off.
The switch powers the board on/off.
If required you can cut the speaker away from the board with a hacksaw in order to position it further from the main board. Recommended not to position it more than a metre away to ensure a good connection but more experiments required on distance range. When cutting the board be carefully of inhaling the dust, it contains fibreglass.
If you cut the speaker for repositioning you can reconnect the speaker boy connecting ‘A’ to an ‘a’ and ‘B’ to a ‘b’. the plastic guard is marked with a ‘+’ and ‘-‘ to denote each side.
There is a trim pot (potentiometer) between the switch and the dfplayer. Clockwise increases sensitivity, counter-clockwise decreases sensitivity. This is useful if the antenna signal is not responding accurately to touch signals.
Stitch a conductive element to this connecting pad, which will be used to trigger the sound. Conductive thread with resistance of approx 6.5 OHM seems to work best but more testing required.
We welcome any queries, feedback or suggestions on further development of this board so please contact us.
