    years ago I built this 8 channel user definable touch pad. It came in a kit form and I havnt really used it to its full potential till now.. on my marine tank :thumbup:

    some more info in the actual unit here

    basically its a touch screen split up into 8 segments. now behind the touch screen glass there isn't an actual lcd screen. instead, you print what you want onto a transparency and put it behind the touch screen glass. each segment has an output that you can do whatever with.

    So I opened up an old multi-plug and modified it a bit. took the switches out and replaced them with 10A relays which are controlled by the touch pad. I put a 12v transformer inside for the touch pad power supply.

    Here's some pics:

    It sends a logic signal to the relays ....1 or 0....LOL :lol: dunno what im saying....
    I think it switches the items connected to the modified multiplug on/off, so that you can 'hide' the multiplug and instead control it with the neat little fancy touch screen.

    so instead of using the switch on the plug bar you using a touch screen? LAZY LAZY LAZY

    right where can I get one :)

    very cool idea as you can hide your "multi adaptor" away

    lol ya we should:lol: can compare tanks and yaris sound :thumbup:

    R100 for multi plug
    about R500 for touch pad
    R5 each for 10A relay
    some wire.

    so about R650

    pretty much spot on hey guys. I hate having to open up and reach in to either unplug or switch off an item. most multi plugs dont even have switches on the 2 pin plugs which is the majority of out items. so now i just plug everything in, hide it away and put the touch pad outside.

    lol ok seems a few people want them.

    here's the deal iv proposed:
    R577.32 for the touch pad. price from electronics 123 here
    R100 for multiplug unless you have your own thats similar to mine.
    R50 rand for 10 relays.
    couple frags for labour. :razz:

    price may change as item is located in jhb and im in durban so shipping charges have to be taken care of.

    if anyone is keen to try themself il be willing to help. the instructions that come with those kits are very very thorough and everything is very well marked. just need basic soldering skills.

    the wiring of the multiplug is also straight forward, some basic electrical work.

    I could help build for the guys in JHB brett just let me know how you squeezed them all into the adaptor.

    do you run an individual wire per relay? - seems it would be the only way to get them to switch

    sounds like a plan. doesnt make sense sending it down here and back up again.

    that grey wire running between the touch pad and multiplug is a 10 core cable. 2 for power and 8 for the relays. each strand is 0.25mm.

    Like an Ethernet cable

    why do you use 2 for power? just because of the size of the strand?

    2 for power. one negative, one positive :razz:

    ethernet is 8 core unfortunately. would be nice to use as its so cheap but it needs to minimum 10 core

    I am confused on the relay if you put 12V power relay is on yes? so all one needs to run from the unit is 1 common & 8 + to switch the relay on or do these work differently?

    also there are only 5 plugs in the adaptor.

    But you using your unit to control all the 2 pins & then some of the 3 pin plugs yes?

    yes when you send 12v to the relay it will switch on.

    The touch pad needs a 12v supply to run the circuit inside it. Thats why you need 10 cores. The 12v supply is in the multiplug.

    The touch pad sends out negative pulses so the relays have a common positive.

    This multi plug has 10 sockets. 5 x 2pin and 5 x 3pin. Im switching 4 2pins and 4 3pins. The other 2 are normal..
