neat multi output psu
« on: July 07, 2015, 07:12:02 pm »
I took apart a Dion freeview digital receiver the other day, found a small but usefull psu with +12v +5v and a 3.3V output on it, handy for a few things I suppose.

Output capacitors will be failing soon, I* just repaired a nice D Link 16 port 10/100 switch by replacing the 2 capacitors on the built in power supply. 1000uF 16V, both bulging. Did the standard upgrade to the mainboard of placing a small heatsink onto the main processor, as they always run too hot, especially in a unit without a fan.

Cost nothing, using parts from another dead SMPS and a heatsink from a dead PC mainboard south bridge. I got the unit for free as not working. Got another smaller 16 port unit as well, same chipset but wall wart powered with a dead wart. That one will simply be powered off the 12V battery providing power to the DSL router or I will look for a working SMPS unit or transformer ( it has a built in SMPS so needs any voltage from 6V to 16V) to drive it.

Right now I would rip your arm of for that switch or any switch !, I have been trying to network 2 win 7 boxes together and a xp machine. box a,b,c box c being xp. box a can see box b on the net and access it, box b can see a but not access it, I am not into homegroups as it causes problems between xp ( box c )and win 7 when communicating. Anyway, nothing I do on any of the boxes lets box b access box a or c. I am personaly now of the opinion that it is something to do with the nasty bt homehub2 router I have. So a switch may be the answer, just cant afford one at present.Box a and c are in fact alternatively connected to the same connector.

@Deathwish

Do you have any old home gateways lying around?  They tend to work fine as switches, provided you turn them on after you turn your main gateway device on (otherwise it will take the role of DHCP server and start handing out ips).  I've been running one from my last ISP in my bedroom for a while now.

Are you trying to get SAMBA shares working between the PCs?  What is it you actually want to use the interoperability for?
