I REALLY want one! Reminds me when I saw my first calculator watch. It had scientific functions.

A comedian once quipped: "I have no idea why they've made a calculator watch, I mean, when was the last time someone asked you for the time, AND the square root of 157?"

There are lots of interesting things still going on in Ohio. And in Arizona. And New Mexico. Maybe Florida, too, but I haven't been there yet to find out. Not your usual suspects though. My favorite was the guy who used to do remote viewing for a three-letter agency. He was here in Dayton a few years ago. Don't know where he is now, but I sure would like to talk with him... this sort of thing is not appropriate for discussion in this forum because AFAIK he did it all without electronics... just his mind and pencil and paper. Paid well during the Cold War, or so I have heard.

Here is a link to a podcast on Remote Viewing. This link is for the first of a two part podcast.

This project looks very interesting

Scavenger wannabe. I look primarily for stuff that has good mass density and volume. And I have acquired some very very expensive and complicated things that sometimes end up in more pieces than my little shed can hold .

When I bought my house (in 1979 - as a single man) what sold it to me was the house was ok, but it was built on a 4 - car garage...
A veritable haven for what is now known as scrap.
I managed to almost fill that garage, that and two cars.
My partner and I still live in that house, but now I have retired, I realise the value of that scrap. So most of the stuff has been dismantled and reduced to scrap. Copper, aluminium, mainly. The steel, and circuit boards.
A fun retirement project that has so far resulted in some considerable $$$.
So, kiddies, the moral (excuse?) for keeping that junk is the scrap value!

I would like to know if anyone has taken out an LCD screen from one of those incredibly cheap digital picture frames? If so, what kind of interface does it require?

Bob

It could be mipi interface or RGB interface, and the drivers for these interfaces may not be universal

So, you want to hear about weird ways to do things with electronics parts.

The resistance of a low resistance metal film resistor can be raised to any higher value by packing the resistor in an oxygen source such as KMnO4 Potassium Nitrate. When a voltage is applied, the resistor heats up until oxygen is released from the powder. The oxygen begins to burn the metal film, which raises the resistance.
When the resistance is so high that the resistor is no longer heated sufficiently to release more oxygen, the resistor is, once again, a stable electronics component.
The finish resistance is set by the applied voltage.

And hey guys
I'm looking for an old video projector, because I'm getting into physics, and I want to play with light.
First up is a Michelson interferometer based measurement tool, which I want to use in conjunction with things that move only micrometers.
(There'll be much electronics involved... )
Is there anyone else on the forum with an active curiosity about quantum physics?

Is there anyone else on the forum with an active curiosity about quantum physics?

When someone talks about particle physics I get a “Hadron” as an LHC large hadron collider

because I'm getting into physics, and I want to play with light.

Me too;what do you propose? I’m on board for whatever!

 

[poormystic]

Wow!
The subject of quantum physics usually only evokes a Wooh-Wooh! response. Yet nobody I know has ever done any practical work at all.
Come on, me! Have a look!

Dot. Dot. Dot.

However it cannot be long now before one of the moderators notices that this thread has strayed beyond electronics. (Hi Dave! Hi Steve! Hi Mr Kapp!)
We might need to go to PM


Still, I better start simple. At school long ago, we looked at a Neon lamp through a double slit made on a carbon-blackened microscope slide. When the slit was very tinily adjusted we could see an interference pattern in the light from the Neon. I'll repeat that.

I'm scared of lasers. I won't have anything to do with one until I have a well- engineered machine to mount it in.
The Michelson is quite a big, expensive job for little me.
