Coronavirus - The Thread :(

Thanks for the nice flash-back Jock !!

Just a comment about the Ariel vs the Honda's sounds: Ariel being a two strokes engine has a power stroke every 360° of crankshaft rotation, both pistons being at the same angular position, we got two explosions at the same time. If I'm not wrong, the Honda was a four strokes engine, this combined with the 180° pistons offset gave the 1,2, pause sound. Would the Honda been a two strokes engine its sound would have been an even 1,2,1,2,1,2 at double the frequency of the Ariel ... (one explosion every 180°).
I can't see any advantage of the Ariel setup: a "180°" two strokes-two cylinders engine is nicely balanced with one piston in power stroke helping the other @ compression stroke, and vice versa, while the Ariel's 360° (or 0°) has to use the inertia to compress the mixture... and shake the all thing !
The only thing I can think of is the simplier crankshaft machining and therefore cost ...

Best regards, Bernard.
Absolutely Bernie. Maybe I was foolish to risk the confusion between two and four stroke engines. The difference i meant to highlight was that the older British four stroke bikes - Triumph, BSA, Norton, AJS, Matchless, etc all had crankshafts where the pistons went up at the same time and down at the same time so the firing impulse was an even Plonk, plonk, plonk, plonk. Whereas the Japanese stuff had a crank with one piston up and one piston down so they went Plonk plonk pause, plonk plonk pause. I much preferred the sound of the old British bikes. Here's an "old" Bonny:

Compare it now with even a new one from the same company, which I think now has the same crank layout as the Japanese bikes I'm thinking of:

The old bike sounds much nicer doesn't it?
By the way, Is it Ok to say Jap when describing these bikes? I wouldn't want to give offence to anyone.
 
A lot of purists didn't recon them because they had a pressed steel frame, not tubing like a "real" bike - but then along came Honda with the 250 Dream and the rest is history - or so they say:

There was a few that scrapped the press frames and converted them into

"Bleaders" or "Barrows".

That consisted of fitting the Ariel engine in a BSA tubed frame, methinks from a Bantam.


I've seen a couple of Bleaders, one in pre 65 trials trim and I think BSA/Ariel (same company at the time) did a factory Scrambler prototype called the TS5 that a factory rider used in the early 60's.

I also fancied building a Trials Bleader when I finished my Tiger Cub trials, though never got around to it.

But the most famous Ariel was a HT5 with the reg GOV 132.

Bleaders? Thanks for that. I never heard of that particular conversion. There were always Tritons, tribsas, etc knocking about in the wider group of people I knocked about with but no one I knew well and they were all faster than anything I owned so I would just be getting there - on my wee James or Bantam D1 (wish I still had that one) - when they were all finished and ready to move on!

Talking about trials cubs brings back the memories. One of our crowd was seriously into trials, did the Scottish 6 day etc, and rode a variety of big name machines - Greeves Bultaco etc, not all owned by him. My best pal, who had the Cub and I, who had a trials Bantam, used to follow him round just to observe and act as backup. Just following him round was hard enough for me!
 
Perhaps being the proud owner of this piece of "tech"

absolves me from the requirement to register? - don't think it could do it?

Nope, you don’t need a smart phone to track a car phone, every time you turn your phone on it’s location can be tracked by the cell phone towers it is near and connects to.

AIUI, for this application, you need a position fix within a couple of metres or so. Tower triangulation isn't sufficiently accurate for this purpose; you need a phone with GPS.

If you're just concerned to monitor the phone to make sure someone isn't moving more than 1/2 mile or so from their home, then yes, a network triangulation fix will suffice for that.

There are also apps that can get a position fix within a few hundred feet by monitoring wireless network signals from fixed routers.

GPS can easily tell which side of the road you're on, and generally is good down to about a metre, providing you have line of sight to the sky.

Given sufficient time and effort, retrospective forensic analysis can probably do significantly better, but for this app, you need something that will work reliably millions of times every day, and that will limit its use to smartphones.

The SSDT is pretty brutal these days as Ross Noble found out the other year (he lives/rides in my area).
Just getting around the course is a feat, let alone riding some of the sections.
It's not the holiday it used to be.


The pre 65 version isn't a picnic either and there are some pretty trick machines out there that owners have spent 10's of thousands on.
Scrutineering must be a nightmare for the organisers, not everything that looks old, is old inside and the rules get tighter every year.


Hope trials is all back running again soon, I'm getting a bit fat and flabby without it!

:rolleyes:

Not sure it was worth you replying.

The more cell cites the more accurate it becomes, You can use a lot more than 3 for a basic triangulation. There are also cell sites with the ability to tell direction and distance of a phone without pinging from multiple locations, there is also hardware the authorities can use to very accurately locate a specific phone in a whole crowd of people, or trick a phone to connect to a false cell to give its location away.

The thing is they don’t like to advertise just how accurately they can track a phone.

You could have looked a bit more into if you’d felt the need.

wouldn't I need to have the program running in the phone for them to know I'm part of the scheme though. Otherwise how would I be differentiated from just any other phone?

Every single phone is unique, so they can track every and any mobile phone, both the sim card that is in the phone and the phone can be tracked separately, So if you put your sim card in a different phone they would know.

Of course the scheme as ben spoke about is not in the UK, their systems might mean your phone wouldn't even work anymore and you need a newer phone.

Also different countries use different signal bands and other technologies we don't use here.


many years ago when I worked with electronics I spent a couple of years repairing phones, but I am by no means an expert, Phone tracking however is fairly basic for the networks and the authorities.

Good job I only switch it on once or twice a week then.

I just spoke to my friend who was in quarantine and I think it might be exaggerated a bit.

It's not using an app and the technical documents I can find about it do state cell tower triangulation, with a mix of all the providers to make it more accurate.

I would have thought it wouldn't know if a phone is stationary or not then, as it's not going to be accurate enough for that - perhaps that part of the story isn't 100% right.

However they do definitely turn up at your house if you turn it off or don't respond to one of the messages in time - that has happened to quite a few people!
 
I’ve had google maps asking me about shops I’ve visited, but I haven’t used google maps, just had my phone sitting in my pocket.
 
my grandma is quite ill in hospital. sadly with her time in hospital she has contracted the dreaded virus.

they found out 4 days ago and only just told us.

sadly lost my grandma to the virus on the 13th.
she went in with a urine infection, caught the virus in hospital, and never left the hospital.

i dont really want any replies back to this post please. just thought you all should know what the outcome was. :(
 
This is the level of intelligence of the anti covid 19 legislation protesters have. The British are now copying them, stupidity is a virus too it seems to be spreading.
