Our main server is now back up and offers a more up to date and complete site.

The resources on this temporary site were a temporary measure to serve the hunger for @ShrimpingIt goodness when Hackaday linked to us and took out our server. Grab us on Twitter or email us if you need anything else or are just interested in collaborating on this project.

What is the project about

We’re trying to curate knowledge how to use breadboard and stripboard to create Arduino-compatible projects for all the non-specialists out there. We’re not a shop, and we aim to make it possible for anyone to follow our information without buying anything from us. The information of where we buy our stuff is at the Bill of Materials page and a minimal guide to build one is available on the Shrimp page.

The aim is that guiding teachers, young people and novice makers through this very flexible and empowering way of working will mean they are in a much better position to cheaply and easily create their own physical computing projects.

One aim is to ensure binary and pin-compatibility, so that any Arduino project can be replicated using a #Shrimp. That’s because there’s a huge community of practitioners, prepared software, resources and project ideas which assume you are using an Arduino.

Substituting the Arduino Uno

We’ve started with a circuit which substitutes for the Arduino Uno, for a cost base of around £1.40. That’s components only, and before P&P or VAT. These prices are most relevant for schools who may be buying a few hundred kits at a time, who don’t pay VAT and where the P&P vanishes rapidly as the volumes go up.

To host the circuit on stripboard costs around another £0.15 based on one third of a Tayda Electronics copper stripboard. To host it on breadboard costs around £0.86 based on buying cheap 170 tie-point solderless breadboards which are used for the canonical layout.

To program the board we use a CP2102 to which we solder a DTR pin. Don’t buy the ones which don’t break out the DTR pin.

Additional complexity to the circuit to host larger numbers components can easily be accommodated by adding extra columns or rows to the stripboard, or buying more 170-point breadboards for the project.

See the recipe page to find out where to buy the bits we’ve bought to prove the approach. So far we’ve put together more than 200 of these kits directly in our own workshops using these components, with a much larger community out there doing the same.


We’re working with local schools to put together example functioning projects which have the Shrimp circuit as a central component. These kits also use the same principle of using generic breadboarding and stripboarding approaches, deliberately moving away from the PCB approach, which we believe disempowers people from remixing their own circuits on an ad hoc basis.

So far, these kits include a Simon Memory game, a Persistence of Vision display, and we hope to put together a Steady Hands game and a Quiz buzzer kit on the same model. We are currently workshopping with local schools, based on a 1-3 hour session including breadboard overlays and other supporting classroom materials to guide students to become Makers themselves.
