If you are planning to be a Zedi this Halloween, you are going to love this, Michelle shows you how to make a quality Zedi Light Sabre from scratch…if you put some cool lasers, you might be able to upgrade it.

There are 4 parts, kinda long, but worth it if you are going to make one.

Here’s a cool circuit for color sensing using minimal circuit components…

Colour sensor is an interesting project for hobbyists. The cir- cuit can sense eight colours, i.e. blue, green and red (primary colours); magenta, yellow and cyan (secondary colours); and black and white. When a primary coloured light ray falls on the system, the glass plate corresponding to that primary colour will allow that specific light to pass through. But the other two glass plates will not allow any light to pass through.

Cool door unlocker based on PIC16F630 microcontroller and a stepper motor…I need this since I’ve broken my door before due

to locking myself in…

Here’s a cool DIY circuit that you can make.

It’s a heart rate monitor that you can use for your next golf outing or jogging.

One day whilst walking through the town centre in Manchester (probably on the way to Maplin!), I came upon a heartbeat measuring machine - here, you had to place a finger into a “thimble”-like sensor, and hey presto, your hearbeat was measured and shown on a large LED display! Back then, I only had a very vague idea as to how something like that actually worked, but after looking in magazines, and tinkering around, I came up with a small circuit.

Here’s a cool adjustable strobe light you can make for your next party or halloween strobe light pumpkin.

This one uses a much more powerful “horse shoe” Xenon tube which produces more light. You can also control the flash rate up to about 20Hz. Do not look directly at the flash tube when this thing is on!

Cool DIY on how to make a cyclon Jack-O-Lantern…

Windell writes in with this incredible Battlestar Galactica Cyclon (robot kind, not meat kind)…. - “For halloween this year, we made Cylon Jack-o-lanterns in both large and small versions. The design consists of two parts, a pumpkin-carving part and an electronics part. The big idea, of course, is to make the Cylon’s red eye scan back and forth. “

I’ve seen some blogs with hovering cars, but this stealth bomber is the coolest gadget I’ve seen so far on Google Earth…

This is pretty amazing. Germany’s Spiegel Online has found a stealth bomber on Google Maps. It should have been blurred out, because it’s on a secret part of a military base — but Google must have missed it. As of this writing, the bomber is still there, in good ol’ Palmdale, California. Hit the link, and zoom out. You’ll see metropolis of Los Angeles emerge just below it. We stumbled on it via Google Blogoscoped, which translates Spiegel saying that it’s prohibited to get close to military bases, let alone photograph them — at least that’s what you’d assume in times of terror. To be clear, the images are obviously not taken real-time; they were taken up to several years ago. Still, it’s got to be a breach to reveal where such bombers may be sitting.
