Apple are generally considered to be best when it comes to protecting their user's privacy (edit: issues like this aside). It does make me wonder what the others are doing.

Did that predate TurboC 1.00? I always used the tiny model in that (being an assembly programmer used to flat memory spaces it was the only way to go).

Very unlikely to be the case here though, in particular because the same receptor domain is found in the wild (e.g. pangolins). Yes, quite a lot of media have become politicised (the reason for which being quite well understood). None the l

>There is convincing evidence it developed via evolutionary origins. Er, yes. Not sure what you're saying here (the title is "..Covid-19 is not a naturally-evolved virus...')?

As noted downthread, these points don't particularly point to it being engineered (point 1 applies in spades to SARS and MERS, for example). Most scientists believe the evidence [0] indicates it's of natural origin. [0] https:&#x

Good ideas though, we've come across the multiple MEMs approach (someone put I think 16 on a single PCB to get 4 times the resolution). The CRM100 [0] we're currently using is the best we've found so far for our application.

Real-time, in fact we're acquiring data at quite a high rate and boiling it down with a view to presenting the results to the rider a few times a second. You can see more at https://bodyrocket.cc if you're interested!

Interesting, but I think we're run out of space. Sort of related, we've been considering how we can gut an optical mouse and use the sensor from them. The idea is broadly similar, basically learn the pattern around one revolution

Nice idea on the laser engraving, maybe we could use that inside the bottom bracket - thanks. We have considered the chain, trouble is both chains and chainrings wear and often cranks/rings aren't terribly-well centred (as fixed g

We're trying to measure aerodynamic drag, thing is there are huge vertical forces (weight of rider pressing down on pedal) and relatively small horizontal forces (due to drag). So if we don't know the angle accurately, we can&#x27

Been meaning to write the project up for almost 15 years now, cameras have moved on so will send a notification once I grab a video (don't hold your breath :)).

Thanks, looked at them. Can't get the resolution we need for any vaguely feasible price though.

Thanks for reply, and do you already work for us? :) We've burnt through a pile of MEMS devices, currently working with CRM100 gyro's. As far as I've got is we definitely need a non-contact solution, either optical or MEMS wi

Good to get your attention :) but still got to print the gray code to 1 part in 8192 and fit it all on a bike. Along the lines of your idea, we've looked at using the CCD array out of desktop scanners with a spiral pattern printed on t

It's not easy to build a high-power narrow-band AM transmitter, let along a broadband one. The issue is the long wavelength makes aerial matching difficult (at 1MHz the wavelength is 300 metres, i.e. speed of light/frequency). AM

No problem, by comparison the old-school weirdo's like full-size keyboards with F1-F10 on the left (compare hitting Control-F8 with the keys on the left compared to above the top row [0]). Really old-school weirdo's were not happy

Yes, I remember them building one of the first digital frame stores at Kingswood Warren, must've been early to mid-80's - huge 14" disk packs with the electronics to digitise/recreate the analogue broadcast-quality video

That's interesting, as I'd assumed the BCPL/B/C progression happened alongside the PDP-7 to PDP-11 progression with the PDP-11 being the design that regularised things. The full set of addressing modes uses 3 bits, thus
