Expertise

Here we highlight some of the expertise and capability we currently poses.

1. Software Development

We mainly use Python ship out small-scale software quickly but use whatever gets the job done.

2. Parts Manufacturing

Our 3D-printing facility enables quick prototyping and on-demand manufacturing. To reflect our open-source values, we have selected open-source printers from the Czech company Prusa Research. Currently, we have 6 of their Prusa Mini printers and 1 Prusa MK3S.

We mainly print from and stock PET-G plastic because of its excellent mechanical properties and good recyclability and safety compared to many other printable plastics.

We can print

• Most common print plastics (PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill) with nozzle temperatures up to 280°C
• Max volume 18x18x18 cm3 (larger parts can done in pieces)
• Dimensional accuracy of +-0.5 mm (often closer to 0.2 mm)

We can also produce varied items via casting techniques. For example, arbitrary-shaped custom lenses from clear epoxy resin for focusing light.

We have limited capability on custom metal, plastic and wood working too. We can produce for example produce and polish flat first-surface mirrors.

3. Electronics Making

We can design simple electrical circuits and devices, and put them together. They can be programmed to read sensors (buttons, temperature, cameras) or take actions (control LEDs, open valves or drive electric motors). For legal reasons, only extra-low voltage devices (under 75V DC or 50V AC) can be designed and made.

4. CAD and 3D Modelling

• Parametric technical modelling | OpenSCAD
• Artistic 3D modelling and animation | Blender
• Ray-traced rendering for photo-realistic output

In 2023, we completed a public engagement project that you can view here: Insect inspired stereo vision.

5. Scientific Consultancy

• Electrophysiological techniques
  • Intracellular recordings
  • Electroretinograms (ERGs)
• Data analysis, modelling and simulations
• Setup building

Dr Kemppainen was trained by two world-class electrophysiology labs in UK and Finland. His background in physics allows him to digest and leverage complex theoretical frameworks, and he has extensive experience in intergrating various scientific equipment into a functional experimental setup.
