PoachedSausage··on How to Design, Build and Test Small Liquid-Fuel Rocket Engines (1967)
You could try talking to the people from the Westmidlands Branch of BIS:

https://www.bis-space.com/branches/regional/bis-west-midland...

I went to some talks organised by them a few years ago. Many of the members worked on rocket propulsion for a local company and had connections to the Rocket Propulsion Establishment.

You are correct. 3G BTS systems used Stirling Cryocoolers[0] to cool superconducting microwave filters[1].

PoachedSausage··on 40 uses for Germanium Diodes (1950) [pdf]
I'm not entirely sure what process is converting to sound, but the metal fence makes a great antenna and we are talking about 10's of feet from the antenna with 500 kW AM at 200 kHz going into it.

It could actually have been arcing:

PoachedSausage··on Embedded Rules of Thumb (2018)
At work we replace an obsolete diode in part of a circuit in front of a high gain amplifier. The new equivalent diode came in a glass package unlike the old one. It caused a bit of head scratching to figure out why the circuit wasn't behaving as it should and also appeared to be acting as a human proximity detector.

>Transmitter Failure Alarm

You would have it installed near your high power transmitter. Having worked on high power AM transmitters, the fences surrounding the antenna can pick up the signal and corroded joints act as a detector, the result is the fence becomes a receiver. So I have no doubt a relay could be powered.

I recently picked up some at a Radio Rally (Hamfest), you might find some gathering dust in the corner of a university or government electronics lab if they have not already gone in the trash.

I have a collection of old printed databooks and application notes from semiconductor manufacturers such a Analog Devices, Philips and Motorola (back when they produced silicon). A lot of the devices are obviously obsolete but the principles from the design examples are still valid.

> Every sensor is a temperature sensor. Some sensors measure other things as well.

Some components can become sensors under the right conditions. Example: Components becoming microphonic.

At high enough frequencies digital design becomes analogue design.

PoachedSausage··on The Vintage Beauty of Soviet Control Rooms (2018)
People were obviously trusted not to be stupid enough to touch them back then. We designed things in Art Deco style, I don't know what the style is now, Health & Safety Mandatory Beige perhaps.

You can see them in action at Avoncroft Museum of Historic Buildings[0] which includes a working telephone exchange.

About a mile from there is Droitwich Transmitting Station, an ArtDeco era station, see page 13 of [1] for exposed knife switches with 400V.

PoachedSausage··on Alterations in glutamate and the experience of ego dissolution with psilocybin
I guess I haven't been that motivated to really look for it, so maybe I'm wrong about availability here.
PoachedSausage··on Alterations in glutamate and the experience of ego dissolution with psilocybin
It is not that popular as a drug and there can't be that many people world-wide capable of producing it.

That is what puts me off trying LSD. It seems that unless you live in the Bay area and are friends with certain organic chemists, your chances of getting good quality, real LSD are slim. However, mushrooms are quite easy to grow.
PoachedSausage··on Alterations in glutamate and the experience of ego dissolution with psilocybin
Thinking back, your experience of the seizure thing sounds similar to what a friend of mine experienced, not with LSD but MDMA. It is possibly related to the motion sickness and brain poisoning reflex.[0]

Also hoping you move towards recovery and it sounds like you have good people in your life to support that.

I would say that a festival (even small and friendly) is possibly not the ideal place to take psychedelics, unless you're very experienced. If you are particularly prone to paranoia, it can surface with psychedelics (even Cannabis) even in good settings.

>modicum of conscientiousness.

Is that common in people suffering from mental ill health?

Reminds me of the ADE651 fake bomb detector[0]. At least people will not die because of this.

My favourite from there:

Always, er never, forget to check your references.
PoachedSausage··on Russian Arctic military exercise draws awe and concern
I wonder what the facility in the background of the photos is and why it wasn't airbrushed out. It looks like some kind radio communications station, VLF for subs?
PoachedSausage··on John Peel Sessions
>Jimi Cauty, who subsequently left 'the orb' to be one half of The KLF. Hence the Peel session of The Orb and the original pressing of the aforementioned track were the only truly awesome stuff they released.

The Orb can certainly be a bit weird at times but there are some absolute gems lurking in the back catalogue and at least Alex Paterson is still releasing music, what has Cauty done recently?

PoachedSausage··on John Peel Sessions
I liked that he would play everything ranging from electronic stuff, drum & bass etc through to industrial and metal. He was truly open minded about music. Back in the 90's his Radio 1 show was followed by Mary Ann Hobbs' The Breezeblock. Another source of great sessions from the electronic music world. She is now on BBC 6 Music, which is probably where Peel would be if he were still with us.
PoachedSausage··on Government to urge us all to walk and cycle more
I am saying that I cannot see how it is morally repugnant to have to pay for the infrastructure that you use.
PoachedSausage··on Government to urge us all to walk and cycle more
The infrastructure to connect your house to the public street network has to built and paid for by someone. It is the same for other types of infrastructure such as gas and electricity. Do you think it morally repugnant to charge people to connect their house to those networks?
PoachedSausage··on Spy Dust (Nitrophenyl Pentadienal)
Presumably you would sprinkle it on the fake secret documents that you left around for the suspected mole to finger, then you have proof who the mole is.

I guess these days they just put a dash of Polonium-210 in your tea and follow you with a Gieger counter, sends a much stronger message.

PoachedSausage··on Are we too busy to enjoy life?
I often wonder if it is true that human nature is unchanging. The proposal comes up often in political debates, but there is not really the place to have an informed discussion about human nature.

It seems to me that human nature has changed quite a lot in the last few hundred years. Examples would be the change in how we view other humans, slavery is regarded as barbaric now, we have the declaration of human rights and equality for women and people of different sexuality etc.

PoachedSausage··on CO2 emissions set to fall nearly 8% this year, the largest drop in history
It might actually. Once you have had one impossible thought before breakfast, subsequent impossible thoughts surely become easier to have.
PoachedSausage··on Wi-Fi over Coax
At frequencies greater than 0 Hz (DC) structures of two or more conductors can support transmission of TEM electromagnetic waves. At microwave frequencies and above it is more efficient to switch to waveguide (a conductive tube).
