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:

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,

Hi,
I read an article in Kalman filtering. There is an example in introductory Mechanics. I just can not understand which formula for calculating the variance and covariance is used. The example is about a vehicle that is traveling straight on the road:
