WiFi Car with camera

That was years later - I worked on the micro television in 1973, IIRC, at St Ives mill. Or brothel as it was widely known

Part of my brief was to design the EHT for the tiny and dreadful CRTs he was trying to build. Using a cheap and tiny piece of ferrite. I bashed my head over air gaps and winding densities and then went back to basics of electromagnetic theory to find a simple way of expressing the problem

And in the end it is indeed extraordinarily simple. You can store a fixed amount of magnetic energy in a given volume of ferrite. Multiply that by the operating frequency (fixed at line scan) and that is simply as much power transfer as you will *ever* get through that ferrite at that frequency.

Better tubes or bigger ferrites was the solution. Nneither was acceptable to Clivce so I spent a few months demoted to the service department full of randy Fen girls, and broken pocket calculators - around a containerful - before leaving to hitch hike round the USA...

The first, but by no means the last criminal to get knighted I have personally known. Of course one other notable knight that I didn't myself personally know was Branson.

Who made his first money by conning students into selling records direct to fellow students at a discount, for nothing, on the promise that they would all receive shares in his company.

No one got anything.

Except him.

Saunders Roe SR-A/1 - I've seen the well-known picture of one taxiing up the Thames but haven't seen it.

Same here.

BTW, have you been to the RAF Museum at Cosford? Its a bit of a trek, but its collection of cold war era jets and prototypes is amazing.

Ironic, as it if it wasn't for Acorn, they wouldn't be a Raspberry Pi, or at least not as we know it.

No, Old Warden and Duxford are my local ones and Hendon isn't too far...so done them

Cosford, the fleet air arm one in the West Country, and maybe Southampton are on the list...

It is strange, but then in the day Cambridge was a hive of invention in the digital arena, and I think if it hadnt been them it would have been someone else.

Curry, Hauser and Sinclair were just the marketeers largely. The underlying tech done by the likes of Sophie wilson was the real 'killer app'.

My friend who worked for Arm reckons it was going nowhere until the mobile boom - and then they just happened to have the right chip and the right marketing model

If Acorn hadn't picked up the BBC contract when Newbury Labs (and then Grundy) dropped the ball with the Newbrain ... or ... if Ferranti had been able to make ULAs that didn't overheat when too many gates were switching at the rated speed ... or ... if Newbury Labs had released the TTL prototype Newbrain like Grundy did and thereby kept the BBC contract ... or ... Then Acorn would never have had the cash to indulge in designing their own processor and we'd probably be using MIPS or SPARC or even Intel Atom processors in our phones and SBCs.

Yes I was right in the middle of all that, from student engineer on the Newbrain to JOAT at Torch fulfilling the CP/M compatibility requirement for Acorn.

A bit more than that - but yes they were the business side of things and they were generally pretty good at the wheeling and dealing and Sinclair was remarkably good at finding the bottom end boom in the market (OK let's draw a veil over the C5 and all of the TVs - although that

1966 one with the 1" tube might have sold if it could have been produced).

For sure, there was a lot of brilliant work going on and a lot of clever people all of whom would have found someone to let them make interesting things.

That would seem to be about right, they were mostly competing with MIPS for routers and the embedded market and not doing so well - ARM always had the edge on power consumption but that didn't really matter until phones put a real premium on power efficiency.

there are a lot of remote controlled devices (like vacuum cleaners) that can do some of what you want.

as for flipping over, you either build it so it won't, or you make it so it doesn't matter if it gets flipped around.

if the 4 wheel base can swivel axially around the middle part, it could run upside down by (literally) flipping over the middle. This might mean retracting a camera if it's on a boom since you probably do not want to see everything from "small animal eyeball" height.

it sounds like an interesting robotics project. You might find one of the various robot kits to be useful.

And of course an RPi to control it.

[To find a charging station, you could have it occasionally beep or use some other means of tracking location within a small area. in addition to GPS for a gross estimate, this could be done pretty easily]
