  • The article is absolute trash for not mentioning this. “Their iconic keyboards…” is the closest it gets to describing them.

    Thankfully, there is a link to the patent at the end.

    Abstract

    A keyboard comprising a plurality of transparent keys. In use, the keyboard is attached to a device such as a mobile device, to overlie a display screen of the device. One or more images displayed on the display screen are made visible to a user through the keys, which may be pressed by a user. User input is determined by identifying a pressed key, and the image or part thereof visible through the key when pressed.

    Basically a detachable keyboard of transparent material as a display overlay, providing tactile feedback while the LCD allows for backlit and customizable key labels. I don’t remember seeing a practical implementation of this IRL or in media but I might be too young for that.



  • This is a retro gaming community, what do you expect?

    Anyway, logic level shifters are cheap and the NES is very well documented. The hardware supplier should have done their homework.

    (Seems like the voltage is being reduced from 5V to 3.3V to power the cartridge chip but there is no level shifting on the data lines, causing excessive current to be supplied from the NES chips’ data pins. It us sunk into protection diodes in the cartridge’s chip as they are trying to pull the voltage to a little over 3.3 volts, raising its supply voltage. The NES works on a relatively low clock speed so maybe the issue can be mitigated by simply adding a resistor network to limit the current but at this point, a proper level shifter costs way less than the rework labor.)
