Re: Is Nuts and Volts dead ?

I am pretty sure that N&V is dead. It seems to have committed suicide about 4 months ago when it last published a magazine. If not dead then at least comatose and unresponsive. I partially agree with Solar3000 that they need a new business model but I also believe that they need a new and more p...

Re: Is Nuts and Volts dead ?

Great news ! I had a reply from "nutsvolts@pubservices" yesterday May 18th which said . . . "Due to mechanical problems with the printer early last year, our publication schedule has been delayed. We have resumed printing, and all delayed issues will be mailed out soon. We apologize f...

Re: Is Nuts and Volts dead ?

Sean.
Might be a good idea if you explained just how we can all check what our subscription status is.
Msondg44 is not the only one with that problem. I too am very confused now by all the delayed issues.
Just how can we check our own subscription status ?

Re: Advice on power bank voltages/power

OK, so here is what I have learnt today 1 Do not use a breadboard to connect low voltage / high current components 2 'Jump' wires are really not good enough for this type of connections 3 Be careful where you measure your voltages Because of the above my measurements were way out. The extra resistan...

Re: Advice on power bank voltages/power

I would think it almost a certainty that any pack would have a current limiter for safety.
However, the slot is rated at 2100ma (with a second one rated at 1000ma).
5v into 7.5 ohm would only draw 666ma so any current limiter would (should) not kick in.

Advice on power bank voltages/power

I decided to test just how much power my external power bank could actually supply over a period of time so set up a simple 7.5 Ohm load resistor across its supposedly 5v 2.1A ouput. It is rated at 5600mah and I did not want to stress the battery too much. The voltage immediately dropped to 3.77v an...
