A low-cost LCD clock with a ‘design your own’ graphic panel that may be slipped in behind the display. The top part of the display flashes on and off each second, revealing then hiding the graphic.
The clock is supplied with leads to explore experimental power sources such as fruit or potatoes. Note that two pairs of different metals (e.g. copper and zinc) in series will be needed to power the clock. Front face size: 45 x 60mm
