Laing DDC pump repair PCB mod

[bmaverick]

Speaking of bumps, anyone know where to buy a cheap DDC? I can't find them for under MSRP of a new one, even for DDC-1s. Ebay has failed me.

If you know of a pump maverick, you will find all of the DDC-1T pumps available, new, with the 50,000+ run hour life fully intact for about $55 less than retail.

So I fitted the White PCb to a Brown/Orange Impellor DDC pump

It worked right away, soldering was very simple.

But its loud, very loud with this BitsPower Minitank i have fitted.

I have a 50k and a 100k Pot on order and i will be fitting it.

The Pot should be connected to the VSP and Vref points on the PCB in the correct way, Once they are connected you need to cut the tiny trace that runs between these two pads on the PCB.

The Pot should then set the speed of the pump and reduce any noise -- Saying all that tho makes it sound like i have done it when infact i havent yet

Yeah, I fixed three of these. When I severed the bridge, the pump stopped working. I still have two of them, but now I won't use them. They are just too loud!!

Fixed up my dead DDC1 with one of his Sanyo PCBs. Ran into a couple of hiccups along the way, the most important of which is that the wires weren't long enough for the new PCB on my pump. Its one of bmaverick's so YMMV on that. Didn't like how bright the LEDs were so I left em off. Still well worth the $10 to bring back a dead pump.

Yes, for only a few dollars, a little handwork along with a little time, getting a DDC 10W to a full 18W sure beats the cost of a new MCP35X any day. Besides, WC started out as a modder's hobby. Today, people want plug-n-play. Only the modder's can state, I built this myself.

They don't sell the PCBs on eBay anymore unfortunately. But I was told that DIYINHK will have a website here sometime in the near future.

Hoping the website works for them.

Mine tends to be so-so since I'm not a web page development person. I have plenty of MCP350 DDC-1T non-functional PCB types if anyone wants to try the mod. Just send me a PM back. The DIYINHK PCB Sanyo board works on these.

DIYINHK PCBs are awesome. I think I managed to get the last one with Toshiba chipset 1-2 months ago. I fixed my burned koolance pmp-400 (DDC 3.25) and now it is better than new.

So does DIYHNK have website or new thread talking about their plans yet?

I know that this thread hasn't had a post in almost a year, but since I was looking for these and found the active DIYINHK website, I figured that I would at least post here that these PCBs (the Sanyo 10W and the white 18W) appear to both be available.
