Oh, check out this cool DIY on how to build an inexpensive Hall Effect Gaussmeter!  If you don’t want to build one, you can always buy a gaussmeter here.

Have you ever wanted to find out how strong a magnet really was, or how the strength of the magnetic field varied as you changed the distance from the magnet or the temperature of the magnet, or how well a shield placed in front of the magnet worked? Voltmeters are fairly inexpensive and easy to find, but where do you purchase a Gaussmeter (also known as a magnetometer). I built a hand-held Gaussmeter for measuring the polarity and strength of a magnetic field. It uses a linear Hall effect device and some op-amps and resistors and things from Radio Shack.

Here’s a good list of magazines that should help you get a feel for the engineering industry including application, products, and just for the hell of it.
(It’s also the ones we subscribe to regularly…)

(Click on the magazine to go to their homepage)

Make has bunch of cool projects including the DIY coffee roaster among other cool stuff… They have a blog too.  (just in case)

Check out CircuitCellar if you are into microcontrollers, embedded systems, embedded linux, etc…etc…

Check out Wired for come wired stuff such as latest stuff about blogging, bloggers, and other cool tech blabbers…yes that got a blog too. Actually, they got a couple of them…

Nuts and Volts is kinda the mix of Make and Circuit Cellar. It’s got some really easy projects you can make.

ControlEngineering’s got some cool industrial information if you are into PLCs, industrial automation, factory automation, etc…etc… (This one is actually not on the stands, but you can get free subscription from their website…)

Extra Note

We do like PopularScience, but everybody probably knows about this one so we will put a link to it. Oh yeah, do check out the Popsci blog…

Hackedgadgets has some free magazines you can subscribe to, you just gotta fill out a short survery. These can be helpful if you are into a smaller niche of the market such as microwaves…

Surprised that NutsandVolts and CircuitCellar doesn’t have a blog yet… you should be blogging, babbling, about stuff…and promote your stuff more!!

Here’s how to make a USB charging flashlight. But you can probably make this work for many other devices that run 5V including MP3 players, cellphones, whatever it is. Just don’t complain if you try to power something less than 5V and blow it up…

After reviewing the Forever Flashlight for The Gadget Panel I couldn’t help but take its capabilities to the next level. I wanted a portable USB charger that could recharge things like my iPod Shuffle. I know there are lots of battery powered options, but I wanted something that didn’t need battery replacement. USB power is 5 Volts and that is exactly what this flashlight puts out on the auxiliary power plug so there is no voltage level conversion required. I also like the fact that this flashlight has Ni-MH batteries inside, not just some big capacitors like some other units.

Cool touchscreen video walls!

One of the characteristics of a successful natural interface is the reduction of cognitive load on people interacting with it: from a presentation perspective, the form of the representation of content is designed to minimize this amount, by reducing the number and the complexity of the stimuli, and allowing a straightforward interpretation of the whole perceived by the subject; from an interaction perspective, this is done by allowing people to rely on interaction schemes they are used to, suggested, afforded by the enhanced environment itself.

Check out voltmeter and ammeter LCD panel you can make using an Atmel8 MCU. Tight!

This multimeter was designed to measure output voltage and current in a PSU, where the current sense shunt resistor is connected in series with load at the negative voltage rail. It needs only one supply voltage that can be acquired from main PSU. An additional function of the multimeter is that it can control (switch on and off) an electric fan used to cool the main heatsink. The power threshold at which the fan switches on can be adjusted using One Touch Button Setup.

Check out this cool laser tester DIY. Very complicated but good source of information if you are into laser testing equipment.

The laser beam spot is the tool in laser welding cutting. Industrial lasers are really great, but there’s a huge problem when it comes to knowing the state of your tool. I mean, in a normal milling machine the mill bit can visually be examined to see if a part of the edge is chipped off. But how does your beam spot look? How is your beam quality? You might have pretty good idea of how good the beam quality is but the truth is: You don’t know. You can’t just look at the laser beam an tell. First of all trying to look at a laser beam without the right safety measures could seriously harm you. Secondly, if you’ve got these measures in place, theres nothing to see. Here’s a guide on how you can build yourself a laser beam analyzer! Get going! It’s great fun!
