The First Inventions: A Repairable Console of Microvision II

    A long history of the Microvision, a first console with interchangeable catridge was launched by Milton Bradley in 1979. However, its small game library, its small screen, and a lack of support from established home video game companies led to its discontinuation in 1981. In this personal project, I revived the original Microvision with new modern project, called Microvision II (codename: Hawk Regine), a new modern look and repairable compliant with EU's 2027 Right to Repair.

With new advanced features and designs look thinner than the original Microvision, this led to work for concept designs that drawn on paper by date in 2024. My original concept of planned to design from hand-drawn paper about concept of Microvision II (known as Microvision II Advanced Console) and X nano within advert-style based designs.

With first to integrate with my own proprietary is Heykers Precision Technology, a new key combined with hall-effect joysticks and the thin mechanical key with just 1.3mm key travel. Featuring the new proprietary chip as Geolite GEO 1000 and 900 series (initial concept), built based on RISC-V boasts the new level of handheld console market. But the proprietary was later discontinued and replaced by ESP32 and RP2040 microcontroller due to chip complexity. It has an interchangeable controllers or detachable controllers, just like Nintendo Switch, Nintendo Switch 2 and Lenovo Legion Go where adopted detachable controllers. This game library supports a SD card slot and digital games that can be downloaded via the internet. This feature for original Microvision game library emulation that would need to be emulated of Intel 8021 and TI TMS1100 CPU, you'll need to download the ROM legally from the internet. Always look the right ROM if you have. 

The screen resolution features LCD IPS display with 800x600 (MV II) and the 900x800 (X nano). It has a detachable controller style such as potentiometer, touchpad, and D-pad, depending on your needs. It can be customized for the interchangeable/detachable controllers.

In 2026, I drawn using a MS Paint to visualize the concept design using a simple lines and shapes to make look simple and easy to read like this in Microvision II as prototype.

This complete makeover with new standard button, unlike original Microvision had problems with button wear, solving the original Microvision (1979) problems which plagued by major problems. To solve this, I designed new own safety in battery is Battery Safety Monitoring System is a custom based on BMS system, integrated to removable battery (MV II) and internal battery (X nano). This sets new gold standard for repairability in the future.

Update: My project had a roadblock. Designing the Geolite 1000 and 900 series was complex and require professional chip design. Ultimately, I switched to microcontroller which commonly used in retro handheld consoles.
