The Lady

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.


The TheLady schematics

Assembly is fairly straightforward, so feel free to figure out how to do it on your own.

Here are the components of the kit

The kit does not come with a battery.

Mounting option by bending the legs into the plaque's four holes

Connecting external power is possible by attaching terminals to the 'eyes' and jumping the solder bridges.

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.

Further information

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.

The TheLady project was Project #4 of the Boldport Club. If you'd like to purchase a kit, become a member and add one to your order through the shop.

The board was lovingly manufactured by European Circuits in Scotland. They also wrote up a blog post with the steps of production!

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.
