Take a look at Parallax's ink jet printer kit that teaches you how simple inkjet technology (thermal inkjet) works. It includes a driver board and an inkjet cartridge for you to play with. There is also a book included that goes through the steps on how inkjet works, etc. You can view the datasheet ...

Alot of compilers have demo versions that are limited by lines of code or by compiled code size. HITech C has a good ANSI C compiler limited by chip type and hex code size. Proton Basic has an excellent, easy to use, IDE + demo that is limited to 31 lines of code and certain processes. I would defin...

Although dell did forget to send me a cd that I paid for one time, so I did an online support chat (I don't want to try deciphering india support) and they sent me every cd possible for my computer (which is worth alot). You ju...

You might as well place it in the printer since it is a big pain to test them. You must use different methods depending on the technology (thermal ink jet, piezo ink jet, bubble jet, etc). Some require somewhat high voltage for very very short periods of time (~22 - 24 vdc). There are also very spec...

Some older desktop video cards have a header on the card that outputs raw digital data that works with some laptop LCDs. There are plenty of pinouts on the internet on how to do this, all you got to do is match up the correct pins to your LCD. The signal names are pretty much standard. This would be...

The only radioshack in my area recently closed because its business was so bad. Everyone started going to Fry's (2 minutes away from the radioshack) and EPO (a surplus electronics place ~10 minutes away). Radioshack seems like it is truely dieing as everyone says. There is simply too much better com...

What compiler are you using? It is pretty important since alot of compilers have built in commands for manipulating the onboard peripherals.

Example compilers would be Basicmicro MBasic, MELab PIC Basic Std/Pro, CCS C, HITech C, Microchip C18, etc. (All these are for PICs)

Sparkfun is 'reselling' a Chinese board manufacturer's service by placing all the designs on one big board / order and sending it to be made. When it comes back, they split up the boards and ship it to the clients. The only problem is that it takes a while for a board to be made. Other than that its...

Sparkfun has this service: http://www.batchpcb.com/index.php . I haven't tried it, but it looks good, and comes from a good company.

Its called SCP or SFTP. Both are secure and based on SSH.

I definitely like all the stamp projects because they can always be ported to other micros with little work as long as you use a compatible basic language. The best thing about these stamp projects are that they have the perfect blend of educational material + hardware design. Not to mention it is e...

Re: Inducing a signal on to Tv to display a message while wa

For svideo, all you need to do is feed the luminance signal through the xbob overlay and feed the luminance back into the svideo output. svideo just seperates the luminance + sync (black and white video ) and crominance (color information). The same goes for component video. I belive one of the colo...

Re: Microsoft Streets and Trips, w/gps GRIPES!!

I use microsoft streets and trips on my pda and my laptop and haven't encountered anything like that before. Of course sometimes there might be a random small road missing, but I don't blame anyone but myself for using an old version. Again, it isn't microsoft's fault for liscensing the map from one...
