Reef Pi Build

[That Crusso Kid]

I was going to suggest Herp.-pi but thought better of it;Wacky

I'd vote for this one! You know, you can still suggest it... :eek:

I wanted to share what an awesome job @Jonathan Troutt did at soldering up these ph boards. I can't even see the numbers on the resistors without magnification.

 

[Ranjib]

That’s awesome . Can you share a photo of the entire board ?

Sure can

 

[Bigtrout]

Mine is on the way!

 

[Jonathan Troutt]

Thanks man I appreciate the kind words. I really enjoy soldering that kind of stuff. Something about watching the paste start to melt and all the little components click into place.

Props are given where they are due. ;Singing

I got the header pins soldered on yesterday and my probe should be here tomorrow. I still need to order the calibration solution and I'm thinking I will get everything wired up and mounted in the enclosure some time today.

That’s awesome let me know if you have any issues.

Will do.

Are you sure that it isn't just breathing in the solder smoke that you like? :)

Hi Diamond, would it bossible to give me and exact list of what to buy to control my viparspectra light?

I have a pi already :) - sorry for the big ask, but I'm the sort where if I have the list, I can then visualise it :(

I'm at work right now but when I get home tonight I will put a lst together for you .

Much appreciated!

Here's a list of what I used for converting my lights

I also used some cat 5 cable I had lying around.

Here's what the circuit looks like.

 

[Diamond1]

The blue wires on the left are the GPIO pins I used.
Yellow wires are 3.3v pwm signals from reef-pi
Black wires are ground.
The pi and board are run from a LM293 buck converter dialed down to 5.1 volts.

This will generate 3.3v pwm, you have ancillary circuit on the LED fixture?

The drivers run on 3.3v. Everything is running straight off of the pi pwm and the relays run from the 5 volt rail. The relays just connect the on/off wires from the driver to 12v from the driver that turns on the individual channels and fans. No extra circuits required.

 

[Ranjib]

Viparspectra comes with 3.3v pwm compatible circuit, I didn't know that. Thats very handy then,

Diamond - legend - thankyou

May aswell get going with the install on the Pi2 :D

 

[ph123uk]

Do I need a PSU? or do I just power the Pi normally with adaptor - i.e. I still have the Kettle lead going into the light.

Im 99% sure this above is a stupid question...
