When we see these cyberdeck builds, the goal is usually to just make something retro-futuristic enough to do William Gibson proud. There’s really no set formula, but offset screens coupled with large keyboards and a vague adherence to 1980s design language seem to be the most important tenets. Granted the recent build by [lewisb42] still […]

Those who have children of their own might argue that the youth of today are getting far too much internet time. [Nick] decided to put an emergency stop to it and made this ingenious internet kill switch to threaten teenagers with. Rather unassuming on the outside, the big red button instantly kills all network traffic as

Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811 LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often.
