Dr. sc. ETH
Thomas Ziemann
With Ziemann Engineering, I am offering my extensive experience in prototype design to companies, research groups, and individuals aiming to transform innovative ideas into functional prototypes. My specialties are power semiconductors, embedded systems and 3D printing, but thanks to my broad experience, I can cover all the steps from idea to reality. Whether you're starting with a rough idea or a clearly defined challenge, I can help you:
- Understand the problem you're trying to solve
- Develop and implement an effective technical solution
- Validate it so that it works reliably, in the real world
On the technical side, this means:
- system design, schematic capture and PCB layout
- CAD modelling, simulation, mechanical fabrication and system integration
- Embedded software, measurement setups and functional testing
About me:
- more than 15 years of experience in PCB design and embedded software
- PhD in electrical engineering (power semiconductor packaging) from ETH Zürich
- lecturer in the MAS Applied Technology program of ETH Zürich - teaching managers prototyping
Would you like a quick consultation? Do you need external prototype development? Do you have a product concept or a research idea, but lack the technical expertise to bring it to life?
Let’s talk. I’m happy to help you take the next step.
Internet-connected key-box for Mehr als Wohnen
The housing cooperative Mehr als Wohnen rents bicycles, rooms and other things to its tenants - but previously, this was only possible during reception opening hours. Borrowing a bike on the weekend? Not possible.
With the new key box, 23 keys or small items can be received and returned around the clock. Bookings are made on the existing web platform, which generates a key code to open the compartment.
This project involved several custom PCBs, connecting the many compartments and integrating a rugged touchpad. The mechanical structure is mostly 3D-printed from robust, translucent PETG, with steel hinges and locks. Last but not least, an API needed to be defined and implemented.
Custom temperature controller for ETH
This compact temperature controller can read different types of sensor elements and control a range of different heaters or thermoelectric coolers. This allows rapidly and accurately heating power transistors to quickly capture temperature-dependent characteristics. Heaters can be selected to optimally match the DUT, and package integrated temperature sensors can be utilized for simple and accurate feedback.
A built-in display shows real-time temperature plots for both channels, making it easy to monitor and adjust thermal behavior during testing.
High power, high voltage, high speed
