With limited DMA-features it's possible to use a GAL 26CV12 instead (solderpad change needed!). The NE555 circuit is not needed if you use the VIA-restore (like in the VIC20). For 256/512KB-chips you ...

A liquid-crystal-based platform has been developed to address optical losses in photonic circuits, which are crucial for advanced technologies like quantum computing and AI.

One of the simple yet interesting connection diagrams that young engineers learn in their lab is the staircase lighting setup.

Creating a GPS tracker is an exciting project, especially for beginners interested in electronics and software development. It’s a project that… ...

集成电路（Integrated Circuit，IC）是一种由许多电子元件组成的电路 ... 测试电路由阻容元件、发光二极管LED、6V直流电源、电源开关S和8脚IC插座组成。将时基集成电路（例如NE555）插信IC插座后，按下电源开关S，若被测时基集成电路正常，则发光二极管LED将闪烁 ...
