Me
About me¶
Hi! I’m Yoshi. I’m Maker and working as management at Japan subsidiary of open-source hardware company.
I’m so into electronics since my elementary school student age. In my high school age, my interest went to internet. After that, in university age, I started my own business (and left univ.). I developed software and built network servers and almost forgot about soldering.
Around 2009, one of my friend told me about Arduino. I was so surprised because when I was junior high school student, we need ROM writer and UV ROM eraser to program microcontrollers. For now, we just need USB and microcontrollers are 32bit and have flash memory!! Technology improvement brought convenient environment for the people!! This improvement reignite my passion for embedded.
As a Maker¶
As a Maker, I enjoyed to join Maker Faire around the world. Here is something I just found from my album.
3D printer¶
I built a few 3D printers but this is the first one. This is Atom, a RepRap 3D printer designed by a Japanese guy. I printed out 3D print parts, purchased components separately and build it. It was around 2013. For now, I love Bambu 3D printers.
Dev board¶
Arm developed their rapid prototyping platform named “mbed” on 2005. I love this environment and added supprt for several MCUs. This was the first project of porting. I did this with one Arm employee in Japan and Arm intern in UK on 2013 summer. We ported in 2 weeks and it was so impressed mbed team.
I designed and manufactured dev board of mbed LPC1114 in 2014. One of the characteristic of mbed is drag-n-drop programing like micro:bit. (micro:bit is also from mbed team) To make this happen, we need to develop a firmware for the interface chip of mbed LPC1114. It wasn’t open-source at 2013 but it become open-sourced on 2014, this is why I designed this board in 2014.
Sadly, Arm Mbed project is going to be shutdown on July 2026. We have FAB26 in July 2026, and 2014 is the year I visited MIT to attend MIT Mini Maker Faire.
As a (student) pilot¶
A new thing I’m working on from last year is receiving private pilot training. My another interest is on aviation, and really want to have pilot license. I started this from June 2025, and suspending this due to finishing Fab Academyš¤£
