FitzRoy’s Glass: Victorian Weather Marvel Or Glorified Thermometer?

August 6, 2026 by 22 Comments

Everyone talks about the weather. This is doubly true for sailors, where bad weather could mean a very bad day. So it isn’t surprising that navies around the world have had a keen interest in weather forecasting. But how did you predict the weather before modern instruments, radar, and satellite images? Vice Admiral Robert FitzRoy had great faith in “storm glasses,” a glass chamber containing some chemicals that he didn’t invent, but did document and promote heavily during the 1860s.

Did it work? Apparently not, but the device is still interesting in its own right. FitzRoy was a pioneer of meteorology, replacing folklore with actual observations and attempts at scientific rigor. While he did arm observation stations with conventional things like thermometers and barometers, he was also a proponent of the weather glass.

Amiga And Commodore, Back Together (Sort Of)

August 6, 2026 by 39 Comments

The story of Commodore, the famous manufacturer of home computers, is a murky one at best. Commodore fans will decry their woeful marketing and dismal product roadmap, while former employees such as our Hackaday colleague [Bil Herd] have shone a bit of light on the goings-on behind the scenes. The company’s final demise in the collapse of the German company Escom scattered its parts to the four winds, but now we find a potential return to clarity.

Amiga Corporation, holders of much of the Commodore and Amiga IP, have reached agreements with Commodore International Corporation, the recently formed face of the Commodore brand, and Hyperion Entertainment BV, who have been behind a series of Amiga developments over recent decades.

The press release provides a fascinating map of the Commodore and Amiga ecosystem as it stands in the 21st century, something which has sometimes eluded fans. As we understand it the rights to the 8-bit IP reside alongside the rights to the Amiga IP with Amiga Corporation, and it’s these 8-bit rights, or at least the software and documentation within them, that have been licensed to Commodore International Corporation. Meanwhile in a separate agreement the rights to continued development of AmigaOS 4.x remain with Hyperion, while the AmigaOS 3.x versions for the 68k Amigas will revert to Amiga Corporation at the end of 2027.

As far as we can see then, this should enable Commodore International Corporation to produce their line of 8-bit Commodore 64s and other machines, while Hyperion continue to serve the AmigaOS 4.x community. The interesting part comes in the AmigaOS 3.x versions, for which Amiga Corporation say they will continue to direct the development and evolution. Does that mean we’ll eventually see a 68k Amiga of some kind licensed through a company such as Commodore International Corporation? It’s an interesting prospect, and a story we’ll follow.

Only The Hottest Tunes Play On This Fire Organ

Most musical organs use air as their working fluid, but there’s nothing in the rule book that says they have to. Calliopes have used steam for 150 years now, while [Look Mum No Computer] has opted to go full pyromaniac and pump propane though the summer’s hottest new instrument.

Just like every steam or compressed-air organ we’ve heard, the tuning could use some work — though we have faith [LMNK] will get to that in due time — and just like the circus organs of yore, it sits upon a trailer for easy transport. That may or may not be to flee from fire marshals, because the whole point of the propane organ isn’t to waste flammable gas: it’s to burn it. The fire itself doesn’t make a sound; that’s the propane going through the copper organ pipes. Igniting it is just bonus, and what a bonus it is!

Said ignition is provided by regular spark plugs and ignition coils, like you’d find in any internal combustion engine. An earlier version used pilot lights, but those had an annoying habit of blowing out and were wasteful of propane to boot. This way the same MIDI signal that controls the gas valve can set the ignition off, and provide a light show to go with the sound. The video embedded below deals with building this new ignition setup, but he has other videos on the channel detailing other aspects of the construction. If you’re not so interested in that and just want a performance, jump right to 16:47 for the obligatory Toccata and Fugue.

Perhaps [LMNK] will write a theme tune for his museum of obsolete technology on this organ, with accompaniment from his rope-core drum machine, and effects on his tape delay synth.
