Hi Jim, Those asm, bin, and hex files are files that are used to program a microcontroller. The ASM file is the code in Assembly Language and can be viewed in any text editor such as Notepad. Viewing the bin and hex files won't help you with anything as they are not really readable anyways (as far a...

How much composite material is on your UAV's and UV's? The company I work for specializes in composite components. Our customers include Bombardier, Boeing, Cessna, Hondajet, ASC Signal (fomerly Andrew Canada), and we are bidding on parts for the F-35 Joint Strike Fighter (http://www.jsf.mil).

Hi, I think the article that you're looking for is called "Self Powered Digital Voltmeter", with the tagline "Build a Nive Add-On for Your Car or Truck and LEarn a New Opamp Trick". It was written by Fernando Garcia and is on page 52 of the July 2004 issue. I can send you a copy of it if you like. C...

You should be able to use your own headphones now. I just got back from a two week trip. I was on four different airplanes and they all had standard headphone jacks. They sold cheap headphones on the plane for $3, or they said you could use your own. I saw a lot of people were using their iPod headp...

Where did you buy it? I know that some large retail stores such as Future Shop, Best Buy, Staples, and Home Depot get special versions and model numbers made just for them. That way the consumer can not use the price match guarentee, because they are unable to find that exact model somewhere else.

It would also be good if those message threads could be added to a new forum (copied, not moved), so we could have a sort of encylopedia of questions and answers.

Ok, I came up with two designs, although I'm not really sure how practical they will be in a real world scenerio. The first one uses a 5 volt source to trigger some darlington transistors with will then flip the track. http://www.postimage.org/gx2R_20r.jpg http://www.postimage.org/gx2R_ZSS.jpg The s...

I always ask the interviewer what he or she likes and dislikes the most about the company, what the culture is like there, and what their turn-over rate is. That should give you a good idea about what kind of place it is.

Yes, that would be the easiest, but it would be no fun. I want to design this for the possible use of a microcontroller or something cool like that.

When the frog is in the resting position, there is 0 volts between the + and -. The 12V is supplied to the frog for only 500ms or so, maybe as low as 300ms. From the outside it looks/acts like a solenoid, it just needs a quick shot of juice to move it. After the frog moves, the voltage goes back to ...

Hi, I've been thinking about this for a few days, and have looked at some H-bridges. The 7912 is cheaper than any H bridge I've found, although I did pick up a couple to try them out. The frog just required a pulse of electricity, like what would come from a momentary switch. Why is an H bridge a be...
