We're developing a new version of Spresense e-violin.
From this version, we try to automatically tune the strings.
As a trial, we attached a single DC motor to pull one string. We also attached piezo pickup, connected to Spresense. The sampled sound is FFTed and the estimated frequency is used to adjust the tension of the string.
In near future, we expect to control four motors by this 3D-printed motor box.
It's a duck aircraft carrier toy that works with bath salts.
This toy runs on bath salts.
This mount attaches your Nintendo switch controller to the SPLA shooter, which allows you to more immerse into Splatoon world.
We also presented this at Maker Faire Tokyo 2018!

There are some LEGO-connectable microcomputer board cases publicly available. The black box in the photo is one of my favorite Raspberry Pi cases. However, there are almost no LEGO cases for batteries!
Therefore, we created a mobile battery case for “Cheero IoT” which is popular for geeks.
You can get one at Toyhack Shop @ DMM.akiba!
We are big fans of micro:bit & LEGO. We tried to harness these two worlds by 3D printed cases for micro:bit itself and its battery board (MI:power by Kitronik) and battery box (Switch science’s dry battery case). You can buy one from our Toyhack Shop @ DMM.akiba, if you live in Japan. The installation video:
GR-LYCHEE is a cute Arduino-compatible ARM Cortex-A RZ/A1LU board with a nice camera module, produce by Renesus. You can get one here. Our model is intended to be the best case of the board when used as a camera, which can contain an easy-to-get dry battery case and an LCD display, as well as a low-cost universal prototyping board sold at Akizuki denshi.On top of the case is the LEGO-compatible attachments, which you can play with.
You can get one at our DMM shop!
With this case, we won the first prize at GR-LYCHEE DESIGN CONTEST 2018.
The Jello Printer is the world’s first food printer (2005).
We proud of it!
