Microwave Plasma Chamber – Part 2 – RF Energy Shielding Primer

There’s a lot of in-depth overview random basic RF information. With that said I don’t mind getting into the details because this information will help keep me safe while I perform experiments in the future. A magnetron generates large amounts of RF energy and emits that energy as an antenna pumped through … Continue reading

Microwave Plasma Chamber – Part 1 – The Plan

Normally I throw together a project with rough notes, research along the way, then after half attempts/failures I get around to cooking that down to a post on here. This time you will get everything. With this project I will be posting my ideas, planning, results of research and the project … Continue reading

SainSmart L293D Fail!!

This is a project in the works but what the hey here’s sort of a preview. The plan is to use 2x 400MHz transceivers via 2x arduinos to control the motors on this RC car. I’ve already taken the original controller board out of the car and made room for … Continue reading

Arduino and UV Lights for Glow in the Dark Decorations

My wife, MrsRedBeard, made some glow in the dark heads for Halloween decorations. They glowed but very dim and not for very long so why not kick it it up with UV lights. But why stop there when there’s an Arduino laying around? Using the Arduino I made it so … Continue reading

DIY 100 Watt Bluetooth Speaker

There’s a trend of bluetooth speakers built into suitcases, ammo cans and other unconventional containers. These things sell for $300 or more which is quite a bit more than what it costs to build them. I will break down the parts, sources and their prices. This project was very easy and very … Continue reading

RedBeard’s Donnie Darko Mask

I’ve been wanting to make a Donnie Darko Frank the Bunny mask for some time now and finally got around to doing before this last Halloween. Disclaimer I’m no sculptor and have no experience with this. Definitely not perfect and I’m going to retry for something better later but I’ll … Continue reading

Parsing Digital Sheet Music MXL Files – Stranger Things Theme Song on Arduino

Arduino Stranger Things

I’ve been toying around with playing music using simple tones on the Arduino. I’m no composer or musician so looking around for sheet music I eventually stumbled across MXL files on a few sites like MuseScore.com. Below I have posted a sample of the Arduino playing the Stranger Things theme song. MXL … Continue reading

Follow up to yesterday’s Hurt My Brain – Is Gravity An Illusion?

Gravity

A follow up to yesterdays article “Oh Reddit how you hurt my brain” highlighting awesome physics talks on Reddit. This is a mind expanding nugget PBS Space Time that started out as a suggestion from Mick who never fails to deliver. This is just a highlight and only one of the PBS Space … Continue reading

Wildcrafting While Taking a Walk

WildCrafting

Honing in my wildcrafting skills during a walk on Monday. Needed a breather and decided to get up from my desk and take a 5 mile walk. Below are some of my finds. I didn’t have my field guide so I was not able to identify some other plants and decided … Continue reading

Creating Plasma in a Microwave

Plasma Preview

After speaking with John Cohn and hearing about this experiment I just had to try it. Video recording is rough but you’ll get the idea. Soon I will be ramping this up when I start my series of microwave oven experiments where we will build everything from a high voltage power supply … Continue reading
