I built one! Arduino Leonardo and a light dependent transistor: https://github.com/willmuldrew/lagmeter (It attempts to do a few other things but it’s best for measuring keyboard event to screen update latency)

There used to be a coffee shop opposite my office that had a pull handle on the push side of the double doors. The right hand side doors were also often locked. I once sat at the nearest table to the doors and watched a dozen people pull th

I had a look into how Jamulus works under the hood. It’s more of a hub and spoke model with the central server receiving, buffering and resending the stream out to each client. This has some advantages (kinder to bandwidth especially as the

Wifi might not be too bad, though it can spontaneously degrade badly if you get interference. Not great in the middle of a jam!

I see 3ms ping times between my friend and I on opposite sides of London, though we’re both on pretty decent broadband tech (me gfast, him some fancy hyperoptic plan). IIUC there are some ADSL technologies that add some minimum latency floo

It’s worth remembering that sound takes 3ms to travel a metre. If you’re standing a few metres away from a drummer then the round trip time is already pushing 20-30 ms of latency and yet you can still play together in a rehearsal room

There’s a great video here that goes through all this - the gist is that USB keyboards specify what polling rate to use, 1000hz for the best ones, maybe 125hz for the cheaper ones. An interesting thing about ps/2 is that even though it

It used to make me sad that by the time my kids were old enough to cycle up big mountains, I might be too old/unfit to join them... but the massive growth in the last few years of electric bikes (mountain and road) makes me really exci

I embarked on a fun lockdown project retrofitting our traditional doorbell (which runs off a 12V AC transformer in the basement) to generate MQTT messages for logging and to trigger notifications (phone, pop-ups on my workstation, sonos noi

I think they do - 5G seems to have the prospect of some realtime low latency guarantee features (though I don’t think it’s rolled out yet). With this in place and an RT audio device you could build an all in one remote jamming box without h

I could look at this in full-res if only I had a multi monitor setup with a million 4k screens!

Me too - jamming at about 15ms lag with Jamulus felt really natural. In fact after months of talking to other people through zoom, just chatting with my friends with low latency, high quality, and without the auto processing/muting tha

I think that’s about a 1000x overestimate - about 1Ah * 1.5v * 3600s = 5400 J - that’d lift 540kgs up a metre (Maybe double that for an alkaline one)

With lockdown keeping me at home, and having to RDP to work over a VPN, I've gone quite far down the rabbit hole this year experimenting with low latency keyboards (1000Hz USB polling, configurable debounce times), gaming mice and high

Our 3 year old had a total meltdown yesterday because I brought him his toothbrush and toothpaste, but in the wrong hands! When you’re tired it’s so easy to take this stuff personally and then all of a sudden you remember that there’s this

I chuckled/was staggered when I heard that the power density in the Sun's core is approximately the same as a compost heap! (albeit a rather large one...) https://en.wikipedia.org/wiki/Solar_core#Energy_conver

Martin Hairer also has a software company making audio editing tools ( https://hairersoft.com/ ) - I love this Fields medal comment in the middle of an otherwise mundane support forum thread about MacOS compatibility! https:
