Martin, the EDU09 only goes to 150 khz. There are 1 MHz kits from China and Quasar Electronics for £20 to £50.

Twin Moke, anyone?

I once broke down on the way to work, ultimately traced to the pin on which the carburettor float hinged, having fallen out, therefore the float chamber filled up causing a grossly rich mixture. The pin being actually 'loose' in its mountings, I persuaded it to stay put by squeezing one end of the pin very hard in the jaws of my pliers, causing longitudinal ridges to form, thereby making it a friction fit which lasted for as long as I kept the car.

I have a 1/4 inch socket set, only cheap, but it does the job. Checking just now, a 3/16 inch socket fits a 2BA tap. My metric set is in the garage, or I would check further, and I am not suitably attired to go outside, people would talk...

John,

If you are close by, you may pick up spurious signals that leak out, or sidelobes from a directional aerial,and which are undetectable from further afield, like the white van parked outside your house, monitoring your tv channels or W-Fi connections, or the phone calls you make on your cordless phone...

I'm told it's the bulkheads that can be a particular problem.

A 'trawler' like an electronic porcupine was (maybe still is) parked off Fylingdales and RAF Irton Moor, despite having caught no fish for years. Also, a colleague who worked you may guess where, said that certain Allied electronic equipment is so designed as NOT to leave a trail of bubbles if thrown overboard...

The Rolson version comes with four sets of lenses, of various powers. I'm thinking of getting one, as I have the same problem, esp. with printed circuit boards.

I rescued a McLaren baby buggy in the hope of acquiring some square and round alloy tubing. I might have to cut it up, as it is held together with tough rivets. Any ideas? How do I get the internal star washers off the axles?

There was one running at MEX. Surrey 7 1/4 inch gauge Society?

There are many cycles, of differing periods, all superimposed. Sometimes they cancel out, sometimes they coincide and build an extra-high peak. (Spring and Neap tides)

When my Dad bought his first new car, he was assured that it incorporated 'sealed for life' bearings. Unfortunately, the 'life' turned out to be 6 months, for the propshaft bearings...

May I suggest a very useful standard? Don't use RCA/Phono connectors!

Geoff

Ady, yes. I've heard that said about mathematicians too. I'm not sure about the cognitive thing. I drive Debs mad when I don't remember even daily things, yet I still absorb and retain information like a sponge. Always have. I'm quite competent and compos mentis (within the meaning of the Act) and lived alone for 20 years up to the Millennium, but I'm more interested in the item of the moment rather than becoming an 'expert' on some narrow subject.

Colin, you are!

I have had this problem with Hermes. I bought off an eBay supplier who sent it via Hermes. It got as far as my street and the person whose door was knocked at said it was not for him. Then it was sent, by Hermes, to a previous customer of the supplier in Suffolk, no idea why. It then sat in a depot somewhere for three weeks and has now disappeared. My supplier has been wonderful, kept me informed, refunded my money without quibble, and we're starting again. Not with Hermes!!!

Well, yes, my experience of metalwork at school was limited to something cut from sheet metal and bent to hang a spade from. That was 60 years ago! As for what's under the bonnet, the first thing you see is designed to protect a pedestrian in a collision. It may be the air filter, or inlet manifold or w-h-y, but it has this secondary purpose too. Underneath, it works just the same as any other i/c engine. Fuel injection has replaced the carburettor, but even that was quite sophisticated by the 1970s. Tamperproofs are to stop the casual interference by the clueless and malign. The necessary fittings are easily available. The STEM programme is good, as are the encouragements for young women to take up engineering. If you want to understand the iPad, you have to start at the bottom, Ohms law, diodes, etc. You wouldn't try to understand a jet fighter without engineering basics either, it's not just electronics which has this characteristic. But, microtechnology is now so cheap that we can make it do complex things and still be affordable.

Join a Mens' Shed, we need to talk to each other. Mine is mostly gardening and woodwork. Makers stood at MEX for a couple of years, but are now big enough to hold their own events. As one who crosses the divide (Industry, amateur radio, computer user) I have an overview, but public understanding of technology is very poor.

I paid £39 from Sheffield, First Class, but I booked it a month ago.

On the other hand, if you find something like marzipan, wrapped in paper tube and sweating, RUN!
