Was ist die TinyGo Keeb Tour 2024?

Die TinyGo Keeb Tour 2024 ist eine praktische Workshop-Veranstaltung, die TinyGo und DIY-Tastaturen kombiniert. Die Teilnehmer verbringen den Vormittag mit Löten, gefolgt von einer Software-Hands-on-Session am Nachmittag. Machen Sie sich keine Sorgen, wenn Sie neu im Löten sind – Werkzeuge werden bereitgestellt und Mitarbeiter stehen Ihnen zur Seite.

Es ist aufregend zu sehen, wie eine Tastatur, die Sie selbst gebaut haben, an einem Computer funktioniert! Das Projekt für die Veranstaltung ist das Zero-kb02-Makropad (12-Tasten-Joystick-Drehgeber-Display). Neben der Funktion als Tastatur oder Makropad kann es auch als Entwicklungsplatine für TinyGo mit zusätzlichen Anschlüssen für verschiedene Zwecke dienen. Mit einem davon können Sie eine Vielzahl von Projekten genießen.

Der Anfang

Am 13. Juni 2024 startete diese Tour mit einem kleinen Team: Micchie, Ysaito, Taknb2nch und Sago35. Als das Projekt wuchs, schlossen sich viele weitere Mitarbeiter an – vielen Dank an alle für ihre harte Arbeit!

Das erste Kickoff-Meeting war für den 1. Juli 2024 geplant. Vor diesem Datum konzentrierten wir uns auf das Design und die Bestellung der PCBs, wobei die aktuelle Version bis zum 16. Juni fertiggestellt sein sollte. Das PCB-Design umfasst ein Matrixlayout und wir haben für eine Anzeige gesorgt wurde mitgeliefert, damit es mit TinyGo wirklich Spaß macht.

Reisen durch Regionen

Die Tour 2024 umfasste vier Regionen:

4. August 2024 – Kobe mit KOBE.go

Unsere erste Veranstaltung! Nachdem wir uns für die Kanto-Veranstaltung am 26. August entschieden hatten, organisierten wir einen Probelauf in Kobe ohne Löten. Wir trafen uns in einer Hack-Bar, genossen Getränke und tauchten in den praktischen Workshop ein, um einen guten Ablauf für zukünftige Sitzungen zu schaffen.

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.

By the second stop on the tour, we had an official T-shirt. The design features a very long gopher holding an ISO Enter key and a soldering iron—such a cool design!

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!

In Sendai, participants created a variety of interesting projects, as expected.

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.

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.

Contributions

The event has inspired contributions to both the TinyGo core and the hands-on workshop materials, which is fantastic.

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!
