Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://www.pcbway.com/

In this video we take a look at an odd sensor add on to an Epson HX-20. This was an eBay find that was odd enough and inexpensive enough to tempt me to pick it up just to have a look. It consists of a modified HX-20 Expansion Unit, a separate external box and some sort of unknown sensor.

Nothing was written on the unit, so we’ll dig in and do some electronic archology to try and determine what its function was. What will we find inside? Join in and find out with us.
