Open Source Hardware
Most of my own projects are released as open source hardware. This means that you can get the source files, make any changes you like, and have them produced yourself. If you decide to publish your changes, I only ask that you do so under the same open source license, and that you credit me with a link to this website.
In addition to my own projects, you will find several other open source projects below.

About AutumnHippo
The AutumnHippo store is run as a hobby project by me -- I'm Thomas, and I am a maker and retro computer fan, based in Denmark.
In my store I offer my own open sourced hardware projects in physical form, as well as a few of other people's open sourced hardware projects. Whether my own or others', my main incentive is to provide an easy way to acquire a retro product, for those who are not comfortable with sending off PCB gerber files to an overseas board manufacturer and sourcing various electronic parts, often from multiple suppliers and vendors -- and for those who just need the product pre-assembled, and working out-of-the-box without any soldering hassle. Oh, and then I sell a few retro related bits and bobs, such as replacement joystick cables, etc., just for good measure.
I try to charge a fair price for everything I sell, and I only charge my actual shipping costs. I do add a bit on top of the product prices compared to the combined price of the parts, in order to be able to pay the bills to Shopify, Paypal, the bank, etc., and for sales to the EU, I need to charge sales tax (VAT) on top as well.
