CNX Software ☛ Pi-Ener-lite – A compact 18650 UPS board for Raspberry Pi Zero with RTC and fuel gauge
Designed by ACE Design Studio in China, the Pi-Ener-lite is a dedicated UPS board made specifically for the Raspberry Pi Zero series. It features a standard flat-top 18650 lithium-ion battery holder and switches to battery power when external power is lost, while supporting simultaneous charging and discharging. The Pi-Ener-lite connects to the bottom of the Raspberry Pi Zero via seven spring-loaded pogo pins that handle both power delivery and I2C data communication, leaving the top GPIO header free for other HATs or expansions.

Hackaday ☛ One Man’s Perfect Retro-Style Monitor Takes All Inputs
We’re particularly taken by the conceit of creating his own packaging for the unit, and going to the effort of filming an unboxing video for a product he made himself. It’s just a bit of silly fun. We’ve seen boxes before, but generally speaking that sort of thing is saved for when a project becomes a product.

Hackaday ☛ Toy Computer Restored
In the 1960s, the home computer was barely a twinkle in anyone’s eye. This was the decade in which computers were used by a handful of companies and organizations and took up entire rooms. It was the decade that saw the birth of the first integrated-circuit computer, the Apollo Guidance Computer, and, rather strangely, one of the first home computers of sorts: the Digi-Comp 1.
