About
Hi there! My name is Pelle. I graduated from the TU Delft in 2024 and have a background in Electrical Engineering. Since graduating I learned that what I really want to do in life doesn't require a degree at all. It is to make music, instruments, and art.
Slowing down
I always feel like the world is moving too fast. Rushing from place to place, finishing tasks and meetings are what makes up for a lot of our time.
For me, making and listening to music are ways of dialing down. Not just from our day to day tasks, but from life itself. Even if the music isn't calm by itself, the moments where I listen to music or create it myself are soothing.
Musical freedom
With my interest in electronics and my love for music, it only made sense to give modular synthesis a try. The modular synthesizer let's you put together your own, unique instrument. Isn't that musical freedom?
For a while I have been building and designing Eurorack modules. It started with using YuSynth schematics and modifying them to get the functionality that I wanted. There are many amazing modules out there, so later I ordered several of those. However, there were puzzle pieces missing. I try to take the ideas that I feel are missing and develop modules out of them.
Electronics and sustainability
I care deeply about our planet, and it worries me that humans have such a negative effect on the environment in many different ways.
Building physical products comes with an environmental cost, and I don't pretend otherwise. What I can do is make careful decisions: Re-using packaging filler material whenever possible, using high-quality components to make the life-cycle of the products as long as possible and estimating the CO2 footprint of a product and offsetting this (scroll down to read more).
Do these measures save the world? No, but sustainability matters to me and at the same time they ensure that our products are produced with care.
Offsetting CO2
It is difficult to know exactly what amount of CO2 was released while manufacturing and shipping our products. A lot depends on the energy sources used (e.g. coal vs renewables) and what components are used. Things that we simply don't have enough information about. There are some estimates on the internet which I used get an idea of the magnitude.
The following table shows estimates of the amount of CO2 equivalent released as a result of a process. The numbers shown are per kilogram of produced electronic equipment or kilogram of shipped product.
| Process: | CO2 equivalent per kg: |
| Electronics manufacturing | 30kg-150kg |
| E-waste processing | 50kg-100kg |
| Shipment (Air travel): China ➝ Netherlands | 4kg |
| Shipment (Air travel): Netherlands ➝ Dallas (US) | 4kg |
| Shipment (Truck): within 1500km distance | <0.1kg |
Using these values, I estimate that the impact of an average Eurorack module including shipment to the US releases approximately 21kg of CO2 equivalent (using the worst case values mentioned in the table). For every module, its CO2 footprint is offset by donating to a fund.
This fund replaces traditional cookstoves used in households in Malawi with more efficient cookstoves. Read more about this project and how it helps the environment (and people) at GreenSpark.
