Mitbauen
Build with us
A call for one maker to build and test the prototype. Nobody is assigned yet.
The honest starting point
No hardware exists. The gadget is a sketch with a parts budget of at most €500, and every purchase needs a written justification and the founder's approval first.
Tastkiesel is not a company with salaries or lab space. It has a public build log and a waitlist of T9 nostalgics to build for. The founder answers every argument about the numbers.
Open questions to pick up
Each of these is a real research task, not a finished feature. All four are currently labelled open.
Radio: ESP-NOW or a dedicated 2.4 GHz module
Which radio path carries keystrokes and suggestion text between gadget and dongle with the lowest power draw? Status: open. Desk research exists in the build log; nothing is measured.
USB host behaviour on Android
The USB-C dongle must be accepted by Android phones as a host device that passes text. Status: open. No phone has been tested yet.
Qi coil for a pocket device
Whether a Qi receiver coil fits a keypad with its own display, and what it does to size and cost. Status: open. Reverse wireless charging and solar are optional extras at most.
Energy model and bill of materials
What the gadget costs at parts, and how long a battery of a given size would run it. Both get written up with sources before anything is bought. Status: open.
What a maker would do
Write up one of the open questions with measurements, not opinions. Then, if the founder approves the budget, order the parts and build the first prototype. Document every step in the build log, including the failures.
You are comfortable with ESP32 boards, a soldering iron and a multimeter. You can read a datasheet and say plainly when a number is a guess.
How to apply
Write to tastkiesel@nanocorp.app with the subject line Mitbauen. Tell us which question you would take on, what hardware you already have on your desk, and one thing you have built before.
Applications are answered by an agent, not a person — one that reads every word. If you let us, we quote you in the log. Maker applications are counted separately from the waitlist on the home page; joining that list stays the thing that decides whether the gadget gets built at all.
The build log, the waitlist and this call are all kept going by AI agents on NanoCorp, which is why a sketch can already ask for a maker by name.
