Build Your Own Class-E Musical Tesla Coil

-

Weā€™ve all seen a million videos online with singing Tesla coils doing their thang. [Zach Armstrong] wasnā€™t content to just watch, though. He went out and built one himself! Even better, heā€™s built a guide for the rest of us, too!

His guide concerns the construction of a Class-E solid state Tesla coil. These are ā€œunderratedā€ in his opinion, as theyā€™re simple, cheap, and incredibly efficient. Some say up to 95% efficient, in fact! Itā€™s not something most Tesla coil fans are concerned with, but itā€™s nice to save the environment while making fun happy sparks, after all.

[Zach]ā€™s guide doesnā€™t just slap down a schematic and call it good. He explains the theory behind it, and the unique features too. He uses an adjustable Schmitt trigger oscillator for the build, and heā€™s naturally given it an audio modulation capability because thatā€™s a good laugh, too.

If youā€™ve ever wanted to convince youā€™re friends youā€™re incredibly smart and science-y, you canā€™t go wrong with a singing Tesla coil. This beats out Jacobā€™s ladder and most other plasma experiments for sheer mad scientist cred.

Have fun out there! Video after the break.

Hackaday Links: May 31, 2020

We begin with sad news indeed as we mark the passing of Marcel van Kervinck on Monday. The name might not ring a bell, but his project, the Gigatron TTL computer , certainly will. We did a deep dive on the microprocessor-less computer a while back, and Marcel was a regular at conferences and on the Gigatron forums, supporting users and extending what the computer can do. He was pretty candid about his health issues, and Iā€™ll add that when I approached him a few weeks ago out of the blue about perhaps doing a Hack Chat about Gigatron, he was brutally honest about how little time he had left and that he wouldnā€™t make it that long. I was blown away by the grace and courage he displayed. His co-conspirator Walter Belger will carry on the Gigatron mission, including joining us for a Hack Chat on June 24. In the meantime, this might be a great time to pick up a Gigatron kit before theyā€™re all sold out and get busy soldering all those delicious through-hole TTL chips. May of 2020 is the mo...

Modern Radio Receiver Architecture: From Regenerative to Direct Conversion

-

Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article . Most of the receivers you will have worked with over the past couple decades are designs by Edwin Armstrong ; regenerative, superregenerative, or most commonly superheterodyne. These are distinguished by a few fascinating key traits that bring both benefits and drawbacks. Today letā€™s dive into Mr. Armstrongā€™s receivers. Iā€™ll also talk about DC receivers which, despite the name, are not made to listen to batteries. These are receivers you are much more likely to encounter in modern equipment. Regenerative and Superregenerative The regenerative receiver is all about doing more with less. You still see some of these in simple applications like RF remote controls. The idea derives from how an oscillator works. In a simple way of thinking, an oscillator is an amplifier with enough positive feedback that any tiny signal at the right frequency will amplify and then, throu...

Homebrew 68K Micro-ATX Computer Runs Its Own OS

Weā€™re no stranger to home built Motorola 68000 computers here at Hackaday, but more often than not, they tend to be an experiment in retro minimalism. The venerable processor is usually joined by only a handful of components, and thereā€™s an excellent chance theyā€™ll have taken up residence on a piece of perfboard. Then [NotArtyom] sent in his Blitz , and launched the bar into the stratosphere. Make no mistake, the Blitz isnā€™t just some simple demo of classic chips. The open hardware motherboard has onboard floppy, IDE, and PS/2 interfaces, with a trio of 8-bit ISA expansion slots for good measure. The  Motorola 68030 CPU is humming along at 50 MHz, with 4 MB of RAM and 512 KB of ROM along for the ride. Designed to fit the Micro-ATX motherboard standard, you can even mount the Blitz in a contemporary PC case and run it on a standard ATX power supply. An earlier prototype of the Blitz motherboard. As if the hardware wasnā€™t impressive enough, [NotArtyom] went ahead and created hi...
