A ladybird soldering
and display kit
We've discovered Coccinellidae Boldportus, a new type of ladybird in Bermondsey, London. After much experimentation in preservation techniques we're sending you a fine specimen for safekeeping. Please take care of it for posterity’s sake.
Assembly is fairly straightforward, so feel free to figure out how to do it on your own.
Here are the components of the kit
- Switch, Bourns, C&K, JS202011SCQN
- 10mm red LED, Kingbright, L-813SRC-B or
- 5mm red LED, Kingbright, L-1503EC
- SMD battery holder, Multicomp, BC-2001
- 12 68Ω resistors, Multicomp, MCF 0.25W 68R
The kit does not come with a battery.
The schematics is pretty basic. Each 'leg' of the TheLady functions as a current limiting resistor that's made of two 68Ω resistors in series.
It is possible to power the board from an external source connecting the power to the 'eyes' and connecting the 'solder bridges' using a solder blob. Make sure not to have the battery inserted when applying external power!
To mount the TheLady onto the mirrored plaque, either used rubber bands (not supplied) or bend the legs after inserting them into the corner holes.
See assembly videos at the end of this page.
TheLady is an open source design, as is most of our work. You can find the design files for the hardware and packaging at our GitHub repository. You can edit the files using our own source software, PCBmodE.

Here's an excellent and fun build video by Alice Stewart
This is an assembly video I've done for a prototype design. Notice that the plaque in the kit is different than the one in the video.
