Re: The Audio-Talk Cycling thread.

I've committed to two charity rides this year. In May I'm riding the Air Ambulance Coast to Coast again, 55 miles from Watchet to West Bay. I really enjoyed it when I took part in 2017. On July 8th I'm organising a charity ride under the auspices of my workplace's adopted charity for 2019, Mind. It...

Re: The Audio-Talk Cycling thread.

Good stuff Nick. You've got enough riders for a SE Audio-Talk club run - maybe I'll get the train over and join you. Thanks! Sounds like a plan. I'm away the next few weeks (hiking in Jordan) but back mid March. I'm not very fit - so frustrating as this time last year I was the fittest I've been fo...

Re: The Audio-Talk Cycling thread.

First (short) ride out... First bit very slow as was with SWMBO and she had bad DOMS as did the very hilly TW half marathon on Sunday. She turned back and I went on. Very happy to hit 50 km/h and average 20 (including the slow first few km) (30-37 on the flats) as route has some sharp hills. 250mts ...

4 miles! Awesomeness!

Can't go out today - SWMBO doing a tough half-marathon so I'm off to AudioJumble....

Tomorrow, hopefully...

Re: The Audio-Talk Cycling thread.

Picked up new bike this afternoon, had last adjustments made, and cycled to Charing cross. Forgot how batshit crazy cycling in London is... Cycled home from local station. Couple of decent hills. Panting hard, but didn't stop. Incredibly smooth compared with old t'bike - just whizzes along.... Came ...

Re: Warning LED when valve stops conducting - a little SS help needed

Been following this with interest. There are isolated integrated current monitors that are not hall effect and thus good for low currents. With an isolated monitor, one PSU is enough and even its isolation is not critical as the monitors are typically good for 1kv or so. I'll look for suitable candi...

Re: Warning LED when valve stops conducting - a little SS help needed

Personally, I wouldn't go this route.

I'd use one of the galvanically isolated integrated current sensing ICs from Analog Devices, TI or ST etc . - these introduce a non-inductive small resistance to the sense path. They are very accurate...

Re: Nothing In Particular

In the road just near our house...

There are quite a few buzzards round us, but always sad to sea a dead raptor.

Being sent to the Kent Wildlife Trust to determine cause of death (they nest on KWT land a few 100 metres from us).

Re: Nothing In Particular

Damn! I always have a high protein breakfast (typically scrambled eggs) with our youngest son every morning, and we almost always have a slice of black pudding in there too.

Thanks - I'll avoid BP next time I have the test...

Re: The Audio-Talk Cycling thread.

Bike ordered 😯😱 Should get it next Wednesday. Lots of shiney bits. Obviously, that'll make me a better cyclist. Being half serious, it's based on a fairly standard Trek Domane carbon frame but everything else is custom. Whizzo chainset and brakes... Have to go back and have another fitting before de...

Re: Opticians.

Agreed. The dispensing part, especially if you're in possession of a nonstandard prescription, is vital.

I used to use an old boy in a local village who had been doing this for, as you say, 30 years. He was excellent.
