This camera, seems to be very good value, for the moony. I now know that I have wildlife in my back yard, at night. I would recommend it to other people, who, want to know what goes on at night.

This seems to be a very good little Buck Boost Converter, although it only came this morning. The readings appear to fall within the tolerances. I will make a small bench power supply with it.

This item arrived quickly, considering it was coming from the far east. It works extremely well, and heats a piece of steel, to red hot, in a matter of seconds. Excellent value for the money.

Although the these boring bars only arrived the other day, and I have not yet used any of them, they appear to be very well made in three different shank diameters, giving various degrees of rigidity. I am very pleased with them.

I found this to be a great little oscilloscope - very easy to assemble, and, what's more, it works! I have found it very useful, together with a signal injector, when I was trying to find a fault with an amplifier.

Q: What can I use it for?

gefragt von Roger auf 2018-11-10 08:57:35

Svante If you place them in ammonia they react, creating nitrogen triiodide. You can then isolate the nitrogen triiodide by filtering out or evaporating the remaining ammonia. Nitrogen triiodide is awesome because it’s extremely reactive. The slightest touch will cause it to let out a small bang accompanied by a spectacular puff of purple smoke. However, be safe while handling these chemicals! They can be dangerous if not handled with care.

It took a while to arrive, but, it was worth the wait. It seems to be very well made, and using the 'phone app, made reading the results easy. How do they do it for the money?? Excellent value. now I just need to exercise a lot more, to stay healthy!
