@NickHalden Launchpad's time in the sun is gone, with the price hike to $10. It's crossed the "trivial price, let's get a few" barrier.
@angelatlarge Did you get a chance to study up on MOSFETs driven from GPIOs? That schematic you were going to cobble up, needs cobbling up :-) Ref:
@AnindoGhosh I've bitten the bullet and gone for the SMD option! Above you say "and a 10 kOhm resistor for pull-down from Gate to Source" -- i am not following this -- is my circuit diagram above ok (apart from BJTs instead of MOSFETs)? What resistor settings should I use where? — Brad29 mins ago
A very cheap way to add WiFi to a project, is to use a WiFi router as WiFi hardware. The router needs to be not-so-new in order to be cheap, and must support
Serial/USB or JTAG ports on board
OpenWRT (DD-WRT may work too, but I haven't used DD-WRT for this purpose)

@angelatlarge No, that was Kortuk - He spoke up in support of some chap who managed to get every purist "I'm a real EE" person's panties in a twist by suggesting that MS Excel is a perfectly usable way to generate timing diagrams.
@angelatlarge Because otherwise, at power-up of the board, the gates will be floating, as the GPIOs start out high-impedance. This will cause the LEDs to all turn on, i.e. inrush current for all the LEDs plus all decoupling caps on the board, etc, therefore likely BOOM!
@AnindoGhosh Engineers - We should know that we are here to use what tools we have and get a job done at lowest cost possible. Religious devotion to tools has no place here.
@Kortuk Agreed. Engineers are supposed to solve a problem by the most optimal means at hand, and if the problem isn't clearly stated in the first place, a good engineer decodes this based on experience, insight and some luck.
@Kortuk Be careful, though - or you might face the punishment of the thousand scoldings, from some people :-D
@AnindoGhosh :( I have never used that tool sorry. What i mean by having never done lots of layouts, I have had to fix dozens fix their layouts, but I have never really spent hours on end doing layouts and have never used serious serious tools to do them.
@tigrou I hope it helps, it is very possible that this is not what you were planning to check. If you are looking for overdriving and such I am not sure it is what you want, but I will wish you luck.
@tigrou That is what I thought, you might have something else you were intending. I have seen that on an iPad app before but I dont know of what would let you do that.
@tigrou Asking for software for a specific task is really not a great question, sorry. A couple of the broad ones we have, but generally, getting it to play to your computer is a very very rare thing for an EE to do.
I can see how it would be fun, but it is not something I would ever do, sorry.
i have another question, not related at all to first one : i just discovered 555 IC component some days ago and how great it is (i'm a beginner). is there any other popular, cheap, very versatille IC component (like 555) i should have a look at ? (beside PICs)
I've been getting so jealous of these like 13 year old kids coming on here and asking beginner level electronics questions
Im just like "HOW THE HELL DID YOU GET INTRODUCED TO THIS STUFF AT SUCH A YOUNG AGE?!?!!?"
@tigrou and it just occurred to me: have you not heard of an arduino board? its a small development board based on an AVR microprocessor that has an IMMENSE following.
a truly unbelievable amount of tutorials online about how to do stuff with an arduino, ranging from basic to fairly advanced stuff
