Qu’est-ce que le TinyGo Keeb Tour 2024 ?

Le TinyGo Keeb Tour 2024 est un atelier pratique combinant TinyGo et des claviers DIY. Les participants passent la matinée à souder, suivi d'une séance pratique sur le logiciel l'après-midi. Ne vous inquiétez pas si vous débutez dans le domaine de la soudure : les outils sont fournis et le personnel est disponible pour vous aider.

C'est excitant de voir un clavier que vous avez construit vous-même travailler sur un ordinateur ! Le projet pour l'événement est le macro pad zéro-kb02 (affichage de l'encodeur rotatif du joystick à 12 touches). En plus de fonctionner comme un clavier ou un pavé macro, il peut également servir de carte de développement pour TinyGo avec des ports supplémentaires pour diverses utilisations. Avec l'un d'entre eux, vous pouvez profiter d'une variété de projets.

Le début

Le 13 juin 2024, cette tournée a débuté avec une petite équipe : micchie, ysaito, taknb2nch et sago35. De nombreux autres membres du personnel se sont joints à nous au fur et à mesure que le projet grandissait : merci à tous pour leur travail acharné !

La première réunion de lancement était prévue pour le 1er juillet 2024. Avant cette date, nous nous sommes concentrés sur la conception et la commande des PCB, la version actuelle étant finalisée le 16 juin. La conception du PCB comprend une disposition matricielle et nous avons assuré un affichage a été inclus pour le rendre pleinement agréable avec TinyGo.

Voyager à travers les régions

La tournée 2024 couvrait quatre régions :

4 août 2024 – Kobe avec KOBE.go

Notre premier événement ! Après avoir choisi l'événement Kanto le 26 août, nous avons organisé un essai sans soudure à Kobe. Nous nous sommes réunis dans un hack bar, avons pris un verre et avons plongé dans l'atelier pratique, établissant ainsi un bon déroulement pour les sessions futures.

August 26, 2024 - Kanto with Women Who Go Tokyo

This event included soldering. We found a suitable venue and borrowed equipment like soldering irons from HAKKO and nanbuwks. Despite being new to teaching soldering, we managed successfully.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1827570363586507013-23'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1827570363586507013&theme=dark" } </script>

There was also a session covering the basics of DIY keyboards.

While working through the hands-on activities, participants were free to create whatever they wanted, resulting in some interesting projects.

October 12, 2024 - Sendai with Sendai.go

With knowledge accumulated from the first two events, the Sendai session went smoothly. The tour merchandise was expanded to include a tour towel—quite impressive!

<script> // Detect dark theme var iframe = document.getElementById('tweet-1844911820097847705-733'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1844911820097847705&theme=dark" } </script>

The soldering process went well, with significant improvements in the steps and documentation based on KPT feedback from previous events. Although there were a few minor issues, things progressed smoothly.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1844920215051829758-683'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1844920215051829758&theme=dark" } </script>

We also enjoyed a traditional Imoni-kai (potato stew party)—it was delicious!

<script> // Detect dark theme var iframe = document.getElementById('tweet-1844937065437462537-570'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1844937065437462537&theme=dark" } </script>

October 26, 2024 - Fukuoka with Kizuku.go

The final event of 2024. Documentation was further refined, reducing potential trouble spots.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1849996657875877892-943'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1849996657875877892&theme=dark" } </script>

Participants mainly followed the build guide on their smartphones or other small devices while working.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1850015908787630157-119'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1850015908787630157&theme=dark" } </script>

Even if there were any mistakes, the staff was ready to rework them, so participants could feel at ease!

<script> // Detect dark theme var iframe = document.getElementById('tweet-1850026223176696257-875'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1850026223176696257&theme=dark" } </script>

We also showcased a new MIDI functionality demo specifically for the Fukuoka event. Afterward, we ended up having a spontaneous MIDI session, practically forgetting about the keyboard hands-on workshop!

<script> // Detect dark theme var iframe = document.getElementById('tweet-1850057554614943908-252'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1850057554614943908&theme=dark" } </script>

To wrap up, we took a final group photo to commemorate the tour.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1850100615810367812-300'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1850100615810367812&theme=dark" } </script>

What is the zero-kb02 Hardware Used in the Tour?

The zero-kb02 is a 12-key macro pad specifically designed for the TinyGo Keeb Tour 2024. It includes a rotary encoder and joystick, making it enjoyable for everyday use as a DIY keyboard or macro pad. It also features a screen, allowing it to function as a development board for TinyGo.

As a demo, we’re developing a 2D game engine called Koebiten.

<script> // Detect dark theme var iframe = document.getElementById('tweet-1841091471786852685-809'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=1841091471786852685&theme=dark" } </script>

The Nature of a Tour

Since this is a multi-event tour with the same theme, we’ve been able to gradually improve various aspects over time. For example, we’ve added notes to highlight common soldering mistakes and clarified the front and back sides of the PCB to prevent confusion. We also addressed questions like “How can I display Japanese fonts on the screen?” by adding relevant instructions to the workshop materials.

Upcoming Plans

Planning an Online Event for Year-End

We’d like to hold an online event by the end of the year for people who already own a zero-kb02 or those interested in TinyGo embedded development. Stay tuned!

Interested in Hosting an Event in Your Area?

We’re looking for locations to host events in 2025 and beyond. If you’re interested, please reach out to the staff (micchie, ysaito, sago35, etc.). If there’s a local Go community, we’d love to collaborate with them as well.

Currently, the approach is to let local organizers handle venue selection. Events without soldering are possible (like the initial event in Kobe), but soldering is preferred if possible.

The TinyGo Keeb Tour Continues in 2025

The first event of 2025 is scheduled for January 13 in Takamatsu, Kagawa. We’re also considering additional locations as shown below.

TinyGo Conf!

We’re also planning a TinyGo event called TinyGo Conf in Japan.

In Closing

Thank you to all participants, the staff, and especially micchie, ysaito, and taknb2nch for starting this tour. We look forward to TinyGo Keeb Tour 2025!
