Hello, Because the 79Key requires 10 wires for the TSOP connection, I thought the soldering can be a lot easier using a flat ribbon cable. A 16 wire ribbon cable which lineup correctly on the traces should solder a lot easier than every wire one by one. Anyone who is familiar with the distances between the traces and maybe a cable with the same specs?  The idea:  Thanx. Btw. This is not about any soldering skills or trouble with the installation, but just to make the installation easier, faster and more secure (or whatever you call that  ) |

Well personally...if you go with individual wires, there is technically less to solder...and if you pre tin all the pads before installation...I reckon this is the easiest method

There is less to solder, that's right. But with the flat ribbon cable you can solder all the wires once and there is less change of a bad solder or short between the points. (the last 3 wires of the ribbon are not necessary also, that leaves 13 wires where 10 are used).
I always pre tin the pads.
Anyone with experience?

Well, its a tsop32, 14mmx8mm package, so, the pitch of the pins should be, according to the data sheet (as shown below), 0.5mm. Since you're soldering to the alternate 20mm tsop32 pinout, it should be the same.  Caster. |

Why buy one, when you can buy two for twice the price.

Hi, Thanks Caster420, that is what I wanted to know Now the search for the right distance flatcable can begin. When I find one, I shall post some pictures of the result. |

actually, the maximus 79key comes with a ribboncable clip, so you can simply hook up a ribbon cable when needed.

I do NOT give support by email, PM, ICQ or whatever. Anyone annoying me that way will have his balls removed. With a rusty butterknife. Slowly. And I'll enjoy doing it.

Uhh I dunno where you got that pic from but this is the wired diagram I followed. I used the wires from an old IDE cable. You just peel it apart like a cheesestring  The wires work perfect. I purchased the socket with my passkey, but I wasnt sure about soldering the entire socket down. I thought I would get some serious bridging for sure because I was testing on an old video card. My passkey is still shipping so I wanted to get this board ready for when it arrives so I went ahead and soldered the wires. It doesn't look pretty but I am hoping it still works lol. Maybe I will take a pic and put it up.  |

just a tip ALWAYS make sure your ground and power is short as possible AND that you use 30 gauge wire for power and gnd - this is essential

absolutely not...nearly everything is shorting/crossing - make your wires alot shorter...tin all the pads and solder  gigabite |

It may look like alot of crossing and bridging, but there really is only one questionable solder there when I look at it real close. But we will see.

Well I haven't got my passkey in yet, but I tried booted the system with the drive in and all the wires as is to see if they dvd rom would get power. It was shorted. So I adjusted a few wires and all is good now, boots and reads fine with all the wires connected. Cant wait to get this passkey in so I can mod this, sell my old system and keep this brand new HDMI 360  |
