Arduino shield
thingiverse
This is an arduino shield to buffer and amplify an analog signal before ADC. The gain of the amplifier is 10 but can be modified by changing the resistor values. The card is printed with the 3D printer and the electronic components are inserted in the holes. Then you have to solder the components using their legs or wires (see the picture). The screw-block and arduino connectors must be glued to the card. The board is designed using a graphic interface Circuit3D (https://github.com/jdiouris/circuit3D) which generates an openscad model of the board. This software is a work in progress.
