「爆読みカルタ」は、日本の伝統的な遊びであるカルタを、AI技術を活用して誰でも参加できる形に進化させた新しい遊びです。従来のカルタでは読み手が必要で、遊びに加われないという欠点がありました。また、既製品の絵札では物足りなさを感じることもあります。
そこで「爆読みカルタ」では、手描きの絵札を使用し、右上にひらがな一文字を書き加えます。このカードをアプリで読み取ると、AI（Gemini）が画像を分析し、その文字から始まる読み札の文章を自動生成してくれます。これにより、読み手なしでも全員がプレイヤーとして参加できるようになります。さらに、自作の絵札を使うことで創造性や個性も表現でき、より親しみやすく楽しい遊びになります。二人でも気軽に楽しめる点も魅力です。
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.
"Spresense e-Violin" is a handmade electric violin controlled by Sony's Spresense. This is a brand new, built-from-scratch version of our previous remodeled e-violin. A new feature is lots of LEDs and the ultraviolet LED control that illuminates the bow hair, dyed with fluorescent liquid.

Previous version:
"Narabel Panel" is a transparent acrylic panels toy for infants. It supports learning of colors and numbers in enjoyable manner. The idea came from nursery teacher's daily experience.
This work tried crowdfunding on 2020 February and made immediate success at the very first day!
ELEKIT sells a cute toy grasshopper with solar panels. I used a door vibration sensor, a temperature/humidity sensor, acceleration sensor, and human detection sensor. Also I added a song module taken from Eric Carl’s ‘The Very Quiet Cricket’. This one sends the atmosphere information with BLE and controls home appliances with ECHONET Lite. This development was fun.
This was awarded by the first ELEKIT Contest。

“Doubutsu Sentai Zyuohger (JP HP)”‘s transformation item “Zyuoh Changer” is shaped like a cellphone. Therefore we added a real phone ability by Twilio, Raspberry pi, 3G SIM, and Lightblue Bean. It took as long as 3 months to create this. It was a hard work (After published this article, I realized Qiita is not the place to announce this sort of case study.)

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.

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.
