Rather think that people may be missing the point of conservation. As another poster noted, if one wants a whole ship then simply build a replica and preserve the integrity of the original ship.

Unfortunately, it's not unusual for an error to be made when the post is being sorted in to walks prior to delivery at the local post office, especially as most posties tend to be temps these days. At least around here it tends to be post with the correct house number but for another road entirely.

And one had to actually get up and fiddle knobs to change channel on the T.V. Honestly, don't know how we survived๐Ÿ™„

It might be worth using a wire stripper with an adjustable stop, failing that just cut the conductors to the right length after stripping the insulation. Crimp joints are great when they work, but there are so many variables, especially using consumer type crimp tools and contacts it can be a pain!

Got me too when I installed it in to another PC and forgot to set things up correctly for the mode. Very easy to do if distracted by getting all the settings for the TX etc working right

Assuming the correct wire gauge and crimp tool settings, it's best to only remove just enough insulation for the stripped wire to crimp in the crimp nearest the contact. The rear crimp contact should crimp over the insulation of the wire. Used to find this issue sometimes back when I worked in QA

Personally Phil, I went for the more discrete green one. Very nice bit of kit and works well. Plus made in the UK by a rather friendly and helpful bloke.

Part of the attraction of archeology I suppose, plus its all around us just waiting to be discovered, one of the benefits of living on a relatively small island with a pretty long and interesting history

Can you just imagine how the poor sod who actually lost such a beautiful thing in the bog felt at the time

One might question if this sort of thing could be run on a server rather than on air, and if so would most of the participants notice or care?

Might be why they used PTFE as the dialetric on the linear sensors as that ups the capacity somewhat. One point though is the AC signal drive was, I think was in the low Khz range using a multivibrator circuit rather than Mhz, been rather a long time so I cannot remember the actual frequencies used

The company I used to work at used tubing on the linear sensors and something akin to air spaced variable capacitors on the angular sensors if that helps. With suitable tubing and suitable dialetric i.e PTFE sleeving/bushings the sensor could be made quite compact, but is scalable

I like the kind of thinking that arrives at this solution to production line ceramics decoration. Must have been fun to prototype to work out materials, pressure, dimensions etc though.

Have thought about maybe using a capicitative sensor element instead? Years ago I worked in a company that used this method and if memory serves they were pretty linear.

I imagine you might have mixed feelings about retiring, but you do now get to spend as much time as possible with the dogs which is pretty cool!

Oddly, here in Croydon we did have some snow around 10.00. Started as sleet but soon turned to large fluffy snow flakes. Hasn't settled but it did snow for around 20 minutes.

I think that's true, in most modern games the graphics are pretty impressive with the better processors and memory but the actual game play, that's different. When designing games for the older computers programmers had to focus on the game play to attract users rather than fancy graphics

Not done any programming for years, but back then it was mainly around satellite tracking programs I tweaked to work on the ZX81 as I was in to the RS type satellites at the time. Somewhat "interesting" at times but it was great fun getting in to the works and getting them to work as I wanted

How I remember the joys of that particular method. Hours of painstakingly typing in hundreds of lines of code, the "save" experience on the ZX81, the anxious wait for it to run........and then hours of painstakingly looking through hundreds of lines of code for the tiny error causing it to fail๐Ÿ˜ซ

Been huge changes in the hobby even since I first started both regulatory and in technology. I know some people lament the old days but personally I think we actually have it pretty good right now, certainly for homebrew we have a lot more access to components and info than ever before

Congratulations Dale, compared to some of the people replying I,ve only been licensed 43 years, not that long really. However I did start as a swl back in 1972 when I was 11 when I made my first try set from a HAC kit. Homebrew still my main interest in amateur radio, lots of changes though.

Nice to see Flowers getting more recognition, however I think it's worth remembering that the work at Bletchly Park was the result of a very dedicated and talented team of people without which the allies would not have had the huge success they did in breaking Enigma codes

Unfortunately, along with constitutions ships have a tendency to sink if too many holes are torn in to them.
