Inductors are more like a resistor in series with an ideal inductor, resistors can be inductors as well, and well, capacitors aren’t just simply a capacitance in a package. Little …read more Continue reading Why Is My 470uF Electrolytic Cap More Like 20uF?
Generally, the biggest problem a new ham radio operator will come across when starting out on the high frequency (HF) bands is finding physical space for the antennas. For a …read more Continue reading HF In Small Spaces
Anyone who’s worked with older tube-based equipment will be familiar with the type of vintage electrolytic capacitor which integrated several capacitors into one can. Long obsolete, they can be bought …read more Continue reading Multi-way Capacitor Replacement Without the Pain
When you say “recapping” it conjures up an image of a dusty old chassis with point-to-point wiring with a bunch of dried-out old capacitors or dodgy-looking electrolytics that need replacement. …read more Continue reading Leaky SMD Electrolytics? Try These Brute Force Removal Methods
Ever wonder what’s inside an electrolytic capacitor? Many of us don’t, having had at least a partial glimpse inside after failure of the cap due to old age or crossed …read more Continue reading Learning About Capacitors by Rolling Your Own Electrolytics
Even though Windows and other operating systems constantly remind us to properly eject storage devices before removing them, plenty of people won’t heed those warnings until they finally corrupt a …read more Continue reading Sailor Hat Adds Graceful Shutdown to Pis
Tesla coils are beautiful examples of high voltage hardware, throwing sparks and teaching us about all kinds of fancy phenomena. They can also be quite intimidating to build. [William Fraser], …read more Continue reading Build a Tesla Coil With Just Three Components
Having acquired some piece of old electronic equipment, be it a computer, radio, or some test gear, the temptation is there to plug it in as soon as you’ve lugged …read more Continue reading Protect Vintage Gear with Easy Capacitor Reforming
[Manuel Caldeira] has built a nice electronics work area that would be the envy of many, complete with an under-shelf rail of custom-built instruments that are specific to the needs …read more Continue reading DIY Capacitor Leakage Tester With a Professional Finish
Sometimes when you need a component, the best way to get it is by building it yourself. [North Carolina Prepper] did just that, creating his own trombone-style variable capacitor by …read more Continue reading Making Variable Capacitors By Stretching Aluminium Cans
