Who wants a cheap, simple, Arduino-based LED controller?

muelpaul, you could likely get the Typhon working in that enclosure as-is. You'd just use cables between the board and the butttons/LCDs instead of putting them right on the board. You'd also have to figure out how to get at the PWM header and programming header - again you could use cables and plugs attached to the case, or cut holes in the case that lined up with the headers on the board.
 
OK. Next stupid question. Where can I find the connections for the PWM headers. I know what DWMZ had mentioned earlier in the threads but I am striking out and getting rather frustrated now. Also, what gauge and type of wires should I be using for this and my LED's. Appreciate the help!!
 
The connector is a fairly standard header. Look into ribbon connectors. The current will be minimal so 24-26 is fine or evern smaller. How far are you running the signal?
 
They might. What you are looking for is the type of connector and wire that is on an IDE type hard disk (hope this helps). Those connectors come in multiple size and you are looking for 8 conductor. Sorry i don't know the proper name to find it.
 
With this controller do you have to plug the power cords from your drivers into a timer? Or do you just leave them powered on all the time and use the dimmer control to turn them "on and off".
 
hi,

How do you control your fan for your led build ? :confused:
It's possible to plug fan on a chanel (10V one fo exemple) an use the pwm to control the speed ?
or we need to build a special board to plug to the i2c chanel to control the fans ?

thx guys for the answers .
 
edsreef, if the driver are on a separate supply from the controller than you could use a timer to save some electricity. Even when no power is drawn from a power supply it uses some. If they are on the same one then you might have some start up issues and/or run the battery down quickly.

actarus, not ignoring you , but I don't know. I would think the transistor could allow enough current, but I better let some more knowledgalbe answer for sure.
 
Well given that the 10v supply is rated at 2.2A you should, in theory, be able to run a couple fans off the 10v PWM out. However, the transistor is likely not rated high enough for the current draw of the fans. It shows 0.1A, which most computer fans are at least 160mA IIRC. You could likely replace the 10v transistors with something similar to THIS.

Wait for DWZM to comment, I just quickly went over the BOM.

If you are not worried about speed control, you can try what I did. My fixture has 24VDC coming in to power the CAT4101 drivers, so I wired 2 standard quiet computer fans in series. I run the whole setup on a timer. Keep in mind I'm not using the typhon, though I am using something somewhat similar.
 
Agreed. You MAY be able to run a really low load fan buy this is not really the intention of the circuit and it will not be ideal.

On that note I am working on a new project that will solve this- it is an I2C-based fan and moonlight module that will work with this controller. Stay tuned.
 
Anyone know where I can get one of the ATMEGA328P Arduino-bootloaded Chip from? everywhere I have looked they are out of stock. Also at moderndevice.com, do I just need the standard $7.00 LCD? thanks.
Also does anyone have a spare PCB board for sale?

The Buy section of the Arduino website lists vendors approved to sell Arduino hardware:

Of course there are plenty of vendors selling the bootloaded chips that aren't on that list, but I like to at least start with the official vendors.

Stock levels for ATMega328's (bootloaded or not) are more volatile than the stock market, so if you can't find any in stock, keep checking the usual suspects as they may have a big pile one day, and then none the next day and then a pile the day after that.
 
I got my Arduino w/ the bootlaoder from Mouser.com. Here is there part #: 782-A000048.

I had managed to get all of the parts I needed from them. I had the help of DWZM for some of the transistors that he helped find a suitable replacement for. The LCD display is part #:763-0216K1Z-NSW-BBW. Hope that the info helps.
