    Trying to resurrect a Kessil #2

    I'm currently building a "Kessil controller" which can be set using a local webserver. I don't think they would be big fans of that haha :)

    Trying to resurrect a Kessil #2

    That would be awesome @JVU ! I took a part 8 of Will’s a360we’s and 7 of them have the exact same issue. Do you think the folks at Kessil will support repairing our own lights? I’d expect them to have some reservations since they would lose out on repair costs. In any case, would you be able...

    KH Guardian 3d printed mount

    I can help print as well! Print bed is 400mmx400mm up to 6600mm x 9650mm. Just pay for the amount of material used.

    I thought there was a $5 fee for the blade? I goofed :)

    Bandsaw

    Most commonly used bandsaw for corals is the Gryphon AquaSaw. The club has one that you can rent out for $5 !

    Trying to resurrect a Kessil #2

    Well... kind of. Consider a super special BAR driver circuit like below. If the bypass capacitor malfunctions and shorts internally, yes you could desolder it and the rest of the circuit could work. There are many caveats, but in a very loose sense, this could work. In the Kessil A360WE...

    Trying to resurrect a Kessil #2

    In an ideal case, yes haha but I don’t want to try something in haste and make it worse. So I think I’ll wait till I’m able to create a proper schematic :)

    Trying to resurrect a Kessil #2

    Well, I think they count the MOSFET body diode itself as the flyback diode, which is a terrible design choice. The four inductors and the capacitors seem a lot like an LC ladder filter. Why they would need that, I have no idea. Still need to investigate further. One of the 8 lights is blown...

    Trying to resurrect a Kessil #2

    They use 4x RT8462 as the primary drivers. What puzzles me is that their PCB layout doesn't match any of the suggested driver configurations :/ Also, it seems like the drivers blowing are caused by the LED dies themselves burning out. I am however, able to disconnect the problematic driver and...

    Trying to resurrect a Kessil #2

    @sfsuphysics we have industrial LCR meters at work so that's no big deal at all :) I'm sure I can get compatible components from Digi-Key in my weekly order. @rygh It doesn't seem to be a power trace. The arrangement of the inductors and capacitor looks like a filter circuit for the analog...

    Trying to fix a broken kessil

    I realize this is an old thread, but in case any of you are interested, I was able to get one working (sort of): https://www.bareefers.org/forum/threads/trying-to-resurrect-a-kessil-2.27932/

    Trying to resurrect a Kessil #2

    Welp! Looks like the A360's also have a distinct failure mode. How has Kessil not addressed this issue? In all the lights I've opened, inductors L401, L400 and the ceramic capacitor C403 are blown out. In the section right next to it, which is an identical driver circuit, the corresponding...

    Trying to resurrect a Kessil #2

    Back in September, I picked up a blown Kessil A160 from @Corallus , which was deemed unrepairable due to a blown switching regulator that had burned through multiple layers of the circuit board. Details here. Today, I picked up 8x A360W's from @Wlachnit to try and figure out what was going wrong.

    My version of a Chop Shop!

    I see you all with your frag tanks, and I raise you my version of a chop shop. Thanks @Wlachnit for these! Time to Frankenstein some of these together! It was great to gee you today in 3D, and talk tanks, trains and Italian cars!
