Racing / Etienne Shrdlu Presents… TdF 2021
« Last post by Mr Larrington on Today at 12:43:12 am »
Poo ur gosh doesn’t time fly when you’re having Type 2 fun, eh?  Seems like only yesterday that we at P@nd3m1c Pr0duckt10nzTM® put the final face mask on the jolly spiffing Socially Distanced Tour Ov France 2020 and yet here we all are again for up-to-the-minute hour reportage, potentially libellous falsehoods, and cruel and heartless defamation of Manx Minnow TV's Tiny P Kennaugh.

Those idle buggers at Vsquared haven’t yet seen fit to tell us whether we’re going to get a return to 2019-stylee coverage i.e. sans TV's the C Boardmen but with the Usual Suspects actually in La Belle France and radio's M Smith and victims guests in the dungeon broom cupboard in Londonton, or whether they will again be confined in Sir Henry Rawlinson's prisoner-of-war camp in Kent with only celebrated non-wooden curlifckr TV's D Friebe to hold the selfie stick fort and attempt to decipher the cryptic utterances of S “yeh. er.” Yates in Abroad, where the FOREIGNS come from.  You may, however, rest assured that our coverage may contain:

Or not.

Because the thieving bastards at Microsith have decreed that Excel for FruitCoSlabs now requires a subscription, we are using Mr Google's spreadsheet SCIENCE to generate all the table-formatting Stuffs that only appears to you, Constant Reader, if we've fscked things up at the poof-redding stage.  Hopefully this will work as advertised as otherwise our SCIENCE Minion will start whinging and making unrealistic demands for outlandish Stuffs like a wage, the keys to the Netflix account, a Maserati “just like TV's Super D Millar's” and pictures of Syrah Poulidor-Featherstonehaugh in a State of Undress an extra rat-onna-stick on the rest days.

If you want sensible discussion you know where to find it, which is to say Not Here.  Please read the safety instructions for this thread on the card in the seat pocket in front of you.  The value of the thread may go up as well as down, but probably won't.  Please familiarise yourselves with the location of your nearest emergency exit from the thread.  No animals will be harmed in the making this thread except TV's *** Boulting.  Do not open the doors while the thread is in motion.  Le singe est dans l'arbre, l'ours est dans la fôret and your lifejacket is on top of Mont Ventoux.

I was the happy owner of a 96 vintage Stumpjumper until a recent house move caused me to pass it onto the daughter's boyfriend (of 5 years). He loves it. She loves it when she can get ride it, and wants one just like it, and the same goes for the other millennials in the household. I wish I still had room for it, it was a great all-round ride. Still is, by all accounts  :)
The Stumpjumper lives. The boyfriend is gone and the daughter - very cannily - insisted that she keep the bike. She rode it on a short tour of North Kent last week :-)

She stopped off en route and I tweaked a few things for her: I must say, there was a twinkle in my eye as I worked on it :-)

If the power supply is regulated to a fixed current, is there an increased risk of over-charging? Should I use a timer?

The way a typical bench power supply works is you have a knob for voltage and a knob for current.  Typically, you'd turn the current limit up high enough that it doesn't come into play, set a voltage and treat it as a voltage source (think thing-that-behaves-like-a-battery), supplying a regulated 5V or whatever for your circuit.

Alternatively, you can flip this on its head, turning the voltage right up, then (probably with the output terminals shorted, so you see something on the current meter, unless it's a funky digitally-controlled one) twiddling the current knob to set some value.  Then it behaves like a current source, with the voltage rising to whatever value is needed to push the desired current through the load.  Sort of thing you might want to do to heat up some nichrome wire to cut foam, or drive some sort of electro-chemical reaction.

For battery charging, you'd do a combination of both.  Starting with the output shorted, you'd turn the voltage right up and set some desired current.  Then you'd disconnect the output, and twiddle the voltage down to whatever is the safe limit for the battery.  Now when you connect the battery, the voltage will rise as high as needed to push your desired charging current, but only up to the point where the voltage limit is reached, at which point the current will start to drop.  Effectively, it acts as a constant-current source, then switches to being a constant-voltage source as the battery voltage rises.  Which is about 95% of what a battery charger does (the rest being things like temperature monitoring, cell balancing, timeouts and clever cycling modes to rejuvenate the cells).

A timer's not a bad idea, because there are battery failure modes where it keeps taking power, but does unhelpful things with it like boiling the electrolyte or generating hydrogen.  See also: Explosion Containment Pie Dish™.  I wouldn't charge a lithium-ion battery like this unsupervised, at least not unless you've done it several times before without issue.  Also note the hazard of inviting twiddly knobs that can cause Bad Things to happen if there are other people around (especially those prone to unthinking Tidying Up or who don't respect "Nicht gefingerpoken!" signs).

Thanks for the offer! Unfortunately it's the red 'Workzone' branded one. The blue one is a slightly more sophisticated charger and doesn't quite fit.

Having had a look at the National Rail website and train times to my manor, I'll stick with Whizzybell. I am Quite Excited about this ride.

Mmmmmartin, are you team blue or team red?

The last place on that ride had been bagged by me! See you at breakfast.
Getting to it can be tricky, so i suggest printing out a map of some kind. Once on, it is easy to follow, but the final bit can be complicated. I use a GPX track, a print of a Google map is probably enough.
If you want i can print a section of ordnance survey map for you, and hand it over during the ride. Or you could follow me.
The C&W Way to Canterbury is about 50 minutes, and quicker than trains that involve changes at Strood, Paddock Wood etc. A decent brekkie and a bit of a rest was all i needed before popping to Canterbury, but i was thinner and stronger in those days. I have 28mm tyres and it's not been a problem, but that was some years ago. And once on the outskirts of Canterbury it's downhill all the way.
