Atari ST/STE/Mega ST/STE – connecting to a VGA monitor in color mode 19 March 2023
The Atari ST/STE/Mega ST/STE computers had dedicated monitors to support the graphics modes that were implemented by the engineers who left Commodore with Jack Tramiel in 1984: mono – black and white – 640×400 resolution, 35KHz horizontal frequency, 71Hz vertical frequency – which is available on most VGA monitors color – standard 16 colors from […]
Atari ST / STE: hardware mod gives perfect HDMI picture thanks to the RGB2HDMI and Raspberry Pi Zero 16 June 2022
RGB2HDMI for Atari ST/STE is a great project to add modern video to an old home computer. How old? Atari ST is almost 40 years old (today: 37), based on a 16 /32 bit MC68000 processor with 8MHz clock and a maximum of whole 4MB RAM. Nowadays, almost every new micro-controller is much faster and […]
Raspberry Pi Zero – updating the gate opener with water meter OCR 7 January 2020
Introduction My Raspberry Pi 1B+ has been opening garage and letting me know of the conditions for work nearly 4 years. Recently I’ve decided to replace this 2014 small board computer (SBC) with newer version. I’ve also looked at better (the principle Keep it Small and Simple – KISS) solutions that became available – i.e. […]
Domoticz part 5: Grafana, InfluxDB, Telegraf – beautiful and easy graphs 10 July 2019
Grafana is the answer to the nagging question we’be been asking ourselves over the years – how to quickly and nicely present our data gathered from devices. InfluxDB on the other hand is the database that is as easy and simple to use, thus making it an ideal candidate for this job. Let me show […]
Raspberry Pi 4 – a surprise but also radical change in the project’s direction 25 June 2019
The new Raspberry Pi 4 is a very interesting change in the direction of the original project. Why? I will summarize what we already know, right after the premiere: new CPU, with much more computing power – not because of the clock, but ARM cores in version A72. The execution process – 28nm, is perhaps […]
