LED SABERS / Re: The Flashgun Challenge

Funny...well done!  I imagine that if money were on the line folks might be less inclined for an extension, (or second extension), but betting we are more interested in seeing some cool entries than hitting the date.

I want to reiterate that my saber will not do justice to the extra time, but want to have something entered that works just as a personal goal!

JK. To good of a gif opportunity to pass up.  :cool:

I am looking forward to seeing what you guys all turn out!

Sure, that seems fair.  I don't anticipate any objections, but you never know.

Sounds good...the sooner the better on official word...maybe make sure there is at least a weeks notice either way?  So by the 23rd?

Lets give it a few more days before we officially move the deadline, in case someone comes up with a compelling argument to keep the original.  But man, if September keeps moving this fast, that extra week will feel like nuthin.

Open Source Sound Cards / Re: Proffie2.2 Independent Effect Wiring Help

So, the problem here is that you're going over the power-channel budget, which on a Proffieboard is 6 channels.
You would like to use 8 power channels. (2 for the blade, 1 for the crystal chamber and 5 for the accent LEDS.)

The easy way to get around this limitation is to use pixels some of your accent LEDs. However, if that not an
option, it is still possible to do this using an external FET.  Basically, you could get a FET or PEX to create
an additional power channel. The external power channel won't be PWM capable, but you don't need that to control
neopixels. An external FET could be hooked up to Data3 for instance, and used to control the power to the main blade.
The remaining LEDs will now require 6 channels, which is exactly what you have available.

thank you!  this has been very helpful.

edit:  out of curiosity.  I assume multiple Led's be connected to 1 led pad?  What is the power limit to these pads? Can I connect 2 led's to pad 5 and 2 more led's to pad 6?

Assuming that we're talking about regular LEDs (not neopixels)....
You can connect multiple LEDs to the same pad, but you can of course not control them individually if you do so, they will light up at the same time and with the same intensity.
The power limit for the LED pad depends a fair amount on the air circulation around the chip. The chip is technically capable of 10A per pad, but that only works if the air circulation is good enough. Somewhere around 5A should be pretty safe though.

Yeah, I agree, lets not exclude people, it is, after all, just for funsies. :grin:

Btw, Scott, you can edit your own posts, just click either the "Modify" or the pencil on the right.
Doh!  Long week!

I’m still out but I’ll be happy to see everyone’s work and cast my vote.

Does anyone object to a one week extension?
Nah; not from me. Let’s get as many into this thing as we can.
