I saw a program awhile back and they speculated how in the future Andromeda will be visible in the night sky. I forget their prediction in terms of years, but it is long before the earth is too hot for

Interesting post! Many clocks (analog and digital) use a quarts crystal and a battery. However it is cheap to use the AC utility frequency, especially in things like coffee pots and ovens that have temperature

It is interesting that long before the collision, the, Andromeda galaxy will get easier and easier to see with the naked eye. That is going to be incredible. I wonder what the distance will be before it

Adam, nice post ...right on. I joined steemit after seeing your post on twitter about it (well I joined a month ago, but your persistence helped : -). I am making an effort to write one post a week on

Nice post, and great information. I have a couple points on the zener regulator circuit. You stated that, "The reverse biased zener diode is connected in parallel across the load to ensure that relatively

For accuracy, I should mention In 1742, Swedish astronomer Anders Celsius referenced the freezing point of water as a 100 degree point, and the boiling point of water as the 0 degree point. In 1744, coincident

Great post man!! That malt and hops can looks crazy ...in a good way. It looks fun and successful. I have never tried to homebrew, but I did contribute empty bottles to a friend. Look forward to the updates!

Thanks for the update. I think you have the right idea, as you have to keep trying to find what works. I think the idea to provide feedback for promoted post will help, and is worth a try. --3D

Interesting the regular LED would emit enough IR to function but it makes sense. Also makes me wonder if the IR detector might respond to some visible light too. ...probably a little of both, but more

I always enjoy this theory. It is as if one electron is demultiplexed to hold every state, and the refresh rate is fast enough that only Feynman noticed.

I recently researched this topic when working on a post for a series on temperature measurements. Basically Celsius referenced 0 for freezing, and 100 for the boiling point of water. While Fahrenheit used

Great update, and while I enjoyed them all the, "The Curious Case For Base 12 (Why Dozens Are Easier For Everyday Maths Than Tens)" really hit home. I was research some of that when working on

Nice build, and interesting post. Have you tried to filter the 50Hz? It looks like you have plenty of signal, so it is not necessary. I am interested as using battery power, and still getting noise from

Excellent post! I find beauty in the images but may have to translate for more meaning. Thank you for linking to my work on heat and temperature! --3D

Nice topic. As mentioned in this article, anything greater than CC0 requires citing the source, however it also requires a link to CC license being used. Attribution Example: *"You must give appropriate

The shelf work is quality. I like the way you made the shelf the same height as the desk. Thanks for having a look at my work. --3D

Wow! That was an amazing experience. Thank you for sharing. I am also fascinated by the amount of cabling. While I do not mind elevators, I get uneasy when they are crowded ...looks crowded to me, but

Congratulations to all of the authors of featured post. Special thanks to the editorial team and the SteemSTEAM community. The Distilled series is always fascinating. --3D

I do not know enough to offer an opinion, but looking forward to seeing how it goes. Like you said they both look nice. From just glancing at the specifications they seem like they have similar capabilities

Great post, and as you mentioned epic picture. It is amazing, to say the least, when the night sky offers low optical noise and exposes our galaxy. The tuning fork diagram of galaxies, and classification
