Marcusl, Thank you, I won't do it without safety requirement list. There would be no neighbors where I'd do it. There is a village out of the city I plan to realize the device in, and command by internet from city. The passers-by, yes, is a danger and I must study safety parameters. Well, I...

Davenn, Thank you for the caution notes and answers. Actually, the danger I realized in it, stopped me until now for a whole year. I'm a 36y.o. software engineer, so not that much in kid age to 'play' with danger. To turn back to the project, I defined a small set of rules for me: 1...

Hi, (I'm not native in English, sorry for if bad English) Some background: As a programmer I got more and more distance with physics. I bought a US x-ray tube off ebay to step to a hobby project that naturally keeps me on with refreshing physics knowledge. After the tube came, I jumped...

Hi, I've received a new accelerometer with a scale factor declared in datasheet as: 800 mV/g @ 1.5g. I googled and searched the forum but still can't fully be sure I understand the accelerometer and its functioning, so please correct me where I'm wrong: One thing that very helped me to get...

Thank you! Actually I didn't get a lot, but that the \epsilon = 1 helps as the function goes to infinity when x approaches zero. Puting a = x+\delta/2 I could not figure it out how this is useful.

Hi, in this forum post, exactly at #4: https://www.physicsforums.com/showthread.php?t=52795" after a clarification for uniformly continuous function, it is written that: "...For example, f(x)=\frac{1}{x} is contiuous, but not uniformly continuous on the interval (0,+\infty) " I failed...
