Using USB to power old mobile/handheld computers
I took my old (1989 vintage) laptop out for a coffee to send some tweets & emails 🙂
Bringing an old analog (1G) Cleartone CTN9000 mobile phone handset back to life with the aid of a software-defined radio (Lime SDR) and osmocom_analog.
An app written in 1996 to simulate making voice calls from a Psion Series 3a.
5250 days later – booting an old pentium computer that’s been in storage for ~14.5 years. This filthy beast used to be the defender of the home network running the Smoothwall GPL firewall.
Poking around in the old Psion SIBO SDK debugger – which looks like it’s based heavily on the MC’s GUI…
Re-purposing an old Psion MC400 laptop mechanical keyboard from 1989 to work with USB via a Teensy LC (Arduino compatible) microcontroller
Emulating a Psion MC400 over 30 years later – a 1989 80C86 based laptop being brought back to life in MAME.
Update on the Raspberry Pi/Grafana/Influxdb/DS18B20 temperature monitoring network I put together 2 years ago…
One of the many promises of 5G is accurate time-transfer. I spent a couple of days travelling around the North West of England testing exactly how accurate available time transfer was from commercially deployed 5G installations.
