New Jarduino build gets started

[Chatouille]

How’s your project been coming Dom?

Still not done here, it’s been hard to find the time to finish this project.

Anyways…. here’s where I am so far.







Still have a few tweaks to do.... might order a few more LED's, update Jarduino to 1.2, and work on a cable mount.

I haven't worked on my unit at all. Work's been crazy and I was building a simpler fixture for a friend which I finally finished this week end. Well, not totally finished, looking for a better way to make the connection from the dim4 to the 2 fixtures.
I finally got the rest of my drivers and got a few extra LDD700's and 1000's that were back ordered. I think I'm going to start figuring out the temp sensors and alerts with the Jarduino on my existing tank and leave the lighting until I get my stand and hood built for my 210.

know what you mean about work... been crazy for me too. I found a different schematic to use for the fans that seems to fix issue some ppl were having. I've only tested it out a little, but it works. Let me know if you want it, and I'll post it up after work one night this week.

The temp sensors are really striaght forward to setup, if you need any help, shoot me a pm, and I'll do my best to help.

Lol, is smoke coming out of a transformer a bad thing, hahaha

Ok, so maybe I did something wrong... maybe.

I took this step down transformer and took out the 2 stock resistors. I put a jumper where one resistor was and installed a variable resistor where the other was. Plugged it in and POP!!!! blue smoke, HOLY CRAP!! Fire! lol, extremely exciting.

What did I do wrong???






I tested the variable resistor and the centre leg is the wiper and the other 2 legs are either side of the resistor. I used the back leg so the further out the adjustment screw was the lower the voltage, turn it clockwise and the voltage increased. the unused leg is the one you see sticking out of the variable resistor.

Should have used the newer smoke free ones...duh

Where did the smoke come from Dom?

Ahhhh, but I hear it takes quite the expertise to get these ones to release this particular smoke, lol.

I didnt see if anyone told what you did wrong here and I know your past that but for future reference for anybody else it looks like those 2 original resistors were in parallel and by putting in a jumper you basically jumpered out your variable resistor....ie you removed the resistance from the circuit, hence the smoke!!!
