Welcome to the AutumnHippo store!
New Stuff for Old Computers!
I do various kinds of gadgets and other thingies, usually involving some electronics and not rarely for use with retro computers.
If you like retro computing and gaming, or you are a maker, builder, tinkerer, programmer like me, feel free to have a look around.

Important: Shipments to the USA
20 August 2025
If you're ordering from the USA, please notice that there is a change in how the US authorities are handling incoming shipments from abroad. Previously, any shipment coming into the USA worth under 800 USD was not applicable for customs charges. As per August 29, 2025, this "de minimis" threshold of 800 USD will be removed, which means that:
Going forward, the US authorities will apply tariffs/taxes
and/or fees to all shipments going into the USA, no matter the value.
The Danish postal service has announced that it will be returning all shipments headed for the USA until it has implemented this change from the US authorities. Therefore, I will not be able to send postal packages to the USA for the time being. For now, I have left the FedEx and UPS options available, but I have yet to hear from FedEx and UPS on whether they will do something similar. Likewise, when shipping by post to the USA is (hopefully soon) resumed, I am not aware whether I will have to pre-pay any US tariffs/taxes upon shipping (in which I will have to add that on top of either goods prices or shipping charges), or whether you will have to pay these upon receiving the package.
Time will tell, I guess.
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.
