Tiny oscilloscopes – revisiting the JYETech DSO138 and trying the Raspberry Pi Pico based “scoppy” on Android
Back in Jan 2021 I built the DSO138 tiny oscilloscope kit. Thought I’d dig it out and compare it with the more recent Raspberry Pi Pico based “scoppy” that uses the Pico’s A2D and an Android phone app to display the data
Raspberry Pi Supply Chain Issues – saying hello (again) to the Original Pi Model B Rev 2 512MB
If you’re struggling to find Raspberry Pi Zero (or Zero 2) boards for light IoT applications then an old Pi 1 512MB from 2012 might be the answer…
Tiny clock party – it’s not always about nanoseconds…
A selection of tiny clocks, sync’d a variety of ways – by hand or by (S)NTP/chrony. Featuring Raspberry Pi Pico, ESP32 and micropython.
Out and about with a laptop from 1989
I took my old (1989 vintage) laptop out for a coffee to send some tweets & emails 🙂
Grafana, Influxdb & DS18B20 based home temperature monitoring with Raspberry Pi
An update on the Raspberry Pi/Grafana/Influxdb/DS18B20 home temperature monitoring network I first put together in 2020…
10 years of Raspberry Pi
So the Raspberry Pi has been around for 10 years… everyone’s favourite credit-card-sized computer does just about everything
A SIP trip down memory lane… back to Asterisk PBX & VOIP
A long time ago I built a VOIP PBX. I’ve been wanting to build & use another for a long time and finally got round to it with a £10 Cisco phone and £14 USB dongle…
Using a 30 year old laptop in 2021: The Psion MC400…
A summary of all the things that are right with my 1991 Psion MC400 laptop, “online” via an attached Raspberry Pi 3B+ and wifi…
Psion MC400 – retro computing via RS232 to Raspberry Pi – handshaking fixed…
Getting the 1990s era Psion MC400 laptop online via an attached Raspberry Pi and some custom shortened Psion serial-USB cables… Tweets, Emails, BBC News & screenshots! All in glorious monochrome and at 19200 baud 🙂
RS232 flow-control & handshaking – Psion MC400 retro communications
Connecting my retro-laptop to the internet via 2 x RS232 serial connections to a Raspberry Pi… and defeated (for now) by lack of hardware flow-control signals 😦
Retro & Online – Connecting Psion’s MC400 & Series 3a machines to “the internet”
Connecting 30-year old computers to the internet in 2021… for the LOLs. Revisiting RS232, null-modems and the like, all at 19200 baud.
