It is a simple machine designed for experimentation to provide an in-depth and complete understanding of its operation. It can be placed on almost any table or in any workshop. MSLA resin 3D printing technology can achieve stunning levels of detail and surface finishes that are far superior to what can be achieved with filament 3D printers – primarily by using screen-cured resins such as LCDs on Lite3DP. Although 3D printers with MSLA technology are already available at similar prices to filament printers, they are closed-source projects that eschew one of the most valuable features of modern 3D printing - accessibility.

YugenFlow v2: Compact, easy-to-use, low-power, bi-directional, privacy-respecting thermal detection sensor

YugenFlow v2 is a compact, easy-to-use, low-power smart thermal sensor board that uses low-resolution thermal sensors to detect the presence of people and determine whether they are moving in a given direction. The sensor determines the direction along an axis, the physical meaning of which depends on how the sensor is mounted. YugenFlow does not require motion to detect presence, but can use it to determine orientation. The sensor can detect and "track" up to two people simultaneously from a distance of approximately 40 centimeters. It's also very fast.

Simple 78K/V850/LPC programmer

In early 2005, NEC Electronics launched small-pin-count microcontrollers such as PIC/AVR based on the 78K0S architecture. The 78K architecture has a register set similar to the i8085 and additional bit manipulation instructions. It is said to be a classic architecture, but the memory organization is simpler than PIC/AVR. There are various devices with dedicated peripherals, and the 78K series occupies a considerable share of industrial equipment. In the early days, only OTP/Mask products were available, so they were not popular among electronic crafts. However, the small pin count 78K series with flash memory is getting some attention from Japanese microcontroller geeks. Powerful IDEs (compilers, assemblers, simulators, etc.) are also provided for free. I built a very simple 78K0S flash programming adapter for these devices. Additionally, I built a universal programming adapter for V850ES, LPCxxxx, STM32F, etc.
