Rich: I'm not expert in pretty much anything, but why take the risk? I have been watching this channel for a while now (https://www.youtube.com/user/MrCarlsonsLab), which seems quite an expert on the matter, and he always seems to straight out discard the possibility of reforming caps, preferring re...

Hi: I have made one final refinement to the bias meter. The resistor adding and substracting procedure can be a bit tedious, and the accuracy obtained in the higher ranges is always a bit lackluster. Furthermore, if you are like me (your local electronics supplier is not very well stocked and don't ...

Hi: The low-Z high voltage source proposed by Richard for calibration can be dangerous, specially due to the capacitors needed to reduce ripple. I have devised a method for calibration that doesn't need such a supply. First, connect a standard (10 or 100 mega ohm input impedance) multimeter to the o...

Following from my own personal experience regarding those cheapos, I would second what Richard said. Noise is quite an important issue, specially in your setup where everything is packed close together. Sparking between the contacts of the rotary switch might also be a problem (as it happened to me)...

I will carefully read those documents and also inform myself of any other restrictions present in Spain. It had never crossed my mind the (i)legality of my actions, but not knowing about the law does not excuse one for breaking it.

John /Richard: Could you point me somewhere I could consult those rules? I was completely oblivious of it's existence, and the Americium example you provide is quite shocking, mainly because I see it commonly on the Internet in very popular/good reputation sources (for example, this spanish web page...

Something that bothers me greatly about the video is the high voltage system, since no metering is done and no data presented. Furthermore, If I remember correctly from the cross section chart of the T-T reaction, extremely high voltages would be needed. Those voltages are not present, I would think...

Books are not made like this anymore....
I bet a new book would provide a reference to some obscure paper containing this data without actually posting it and assuming the reader can access it...
Thanks for posting it!

Richard:
You are correct. I did it by impulse from other forums, sorry. I will not make the same mistake again.

Cai Its the weekend here now and I left the book at work where the wonderful photocopier that copies to PDF is i'll try to do it on Monday for you Obviously, there is no rush whatsoever. Thank you very much! I have been searching info on this type of vacuum gauge for about a month with very little ...
