I have an external hard drive, taken from an older computer, in a Dick
Smith external enclosure. During a move I got all the transformers mixed
up and now I do not know whether this requires 12 ...

In some situations the time periods when noise will be an issue are
easy to identify. Instead of subtracting or filtering the noise you
use a comparator to simply shut down the noisy signal until t...Digital Capacitor 1 Farad [9 articles]

I bought a digital 1 farad cap (ICBM-7244CRP) at a swap meet for $15
thinking I could sell it on ebay for a $30 or more.
I'm not sure how it works since it has a 40 amp relay inside to
disconnect...can I run MC1496 (modulator) w/ 80MHz carrier? [2 articles]

Can I run this chip with an 80MHz carrier? I'm trying, but the output is
very weak. The datasheet isn't clear to me. t...Isopropyl Alcohol for Cleaning Flux [33 articles]

In one of the posts about solder, somebody mentioned CVS Drug Store for
91% isopropyl alcohol.
I just called a CVS, it's $2.79 for 16 ounces and $2.99 for 32 ounces.
That's 20 cents more for dou...In the basics of ELECTRONICS. [13 articles]

Anyone like to suggest some improvements to my simulation of a relay
switching a kettle element?
I guessed at all values - the inductor value , no clue what that would be
anyway

Does this mean the circuit analysis requires too much computing
power? It would be nice to get accurate phase angles and amplitudes
as with simple circuits.
