DIY Electronic Impression Pad Instructions
A budget build that turns a children’s LCD drawing pad into a covert impression device for secretly capturing written information.
Free download. Build a covert impression pad for under $10 using a children’s LCD drawing pad.
The guide shows how to choose a suitable pad and convert it into a practical tool for peeks. To the participant it behaves like an ordinary jotter: they write, you clear, and everything looks normal. You obtain the information at a natural off-beat. Parts are easy to source and the build is straightforward, so you can experiment without a large outlay.
