Topic: Gridseed DIY Cables for the newb (Read 5873 times)
I did 5 gridseeds per ATX Molex / SATA. If the wire is smaller than 18 AWG, it will MELT. My current wires are 18 AWG, and none of them are melting after 24 hours.
Here is what I hacked up the other day in case anyone is interested:

Post some pics so ppl can see what you did. Not every one is familiar with the terminology so it would greatly aid them
They haven't been made yet, but the parts are ordered and I will post pics next week.
I will have SOME extras for sale for anyone that doesn't want to make their own. Not many though, as most will be used for my hosted mining service... PM me if you are interested. They can ship out next week.. most parts are in already.
Cheers

A lot of photo made it clear! Probably I will try to do it by myself 
Glad I could help
happy mining

Nice. This is probably what I will try to do. Or something. I might use even thicker wires.
Yah this should hold you off until the professional stuff starts being released in a few weeks or months idk lol
That depends. It's easy enough to make these yourself, DIY. If the professional ones are priced too high, or come from a place too far away from where you are, then it makes sense to just DIY.
For example, network cables. I DIY them all the time. The "professionally crimped" ready to use ones are always priced much more for the same length, so I never buy those. Of course, you'd have to buy the cables first and the RJ45s (the heads), but it gets really cheap to buy a box of 300 meters.
If there was a local provider of these power cables, I'd go to them, but it's easy enough to get fat thick wires from a hardware store, and the power connectors / molex / pcie from your local computer stores. Or hack away your existing wires in your power supplies.
I also make my own big fat extension cords, with big fat power plugs (preferably grounded), because the store bought ones are flimsy and don't support 20 amps of 220 volts.

DIY Gridseed Cables
This is more of a what I've done then a Tutorial. I hope it helps
. Your responsible for your own units do it at your own risk Supply list
1. Molex connector or PCI-E connector to PSU. (You should have some left over from GPU days or buy online )
2. Barrel connector to screw terminal. (http://www.amazon.com/2-1mm-5-5mm-Male-Power-Adapter/dp/B002QWNZHU/ref=sr_1_4?ie=UTF8&qid=1395019577&sr=8-4&keywords=barrel+connector+screw)
3. 18-20 Gauge Speaker Wire (http://www.amazon.com/AH1850N-feet-18-Gauge-Speaker-Wire/dp/B00005T3G2/ref=sr_1_5?ie=UTF8&qid=1395019797&sr=8-5&keywords=18+gauge+speaker+wire)
4. Electrical Tape
Hack Job for Molex
1. First cut your wire as long as you need it. Split the 2 conductor speaker wire like I did and expose the wire. Insert the exposed end into the Barrel plug terminals and tighten the screws so that the wire doesn't come out so easily.
2. Hack off the black end of the molex power connector, and expose the wires.
3. Connect the Speaker wire to the Molex wire, I just twisted the wires together and tape it up with electrical tape. The most Important part is that the speaker wire that is entering the positive terminal of the barrel connector must be connected to the yellow wire of the Molex, and the wire connected to the negative terminal must be connected to the black wire on the Molex connector. If you got the power wires that Lighting Asic sent you for the generic PSU's, the red wire connects with yellow Molex and the white connects with black Molex.
4. Connect your Molex to your modular power PSU cord. Note that you can run at least 1-5 Gridseed on one Molex to PSU how ever here I am only going to be using 4 just to be safe.
Hack Job For PCI-E
1. This is pretty much the same process as the Molex. The only difference I did here is I'm connecting 2 barrel connectors per (yellow and black) wire.
2. You can see here that I actually connected the 2 barrel connectors to one yellow and black pci-e wire.
3. 10 barrel connectors on one pcie. I had 6 yellow wires and 6 black on this power cord for my psu. I have 2 singles and 4 doubles
Finally Done!!!
You can run 4 units like this. I'm not pushing any more than that and wouldn't try it. Check Miaviators thread he states 1-5/molex recommended.
10 units can run on this pcie cord. I believe Miaviator stated we can run up to 10-12 on PCI-E.
