how mutch you pay 3/32 or 3/16 v ? geekbaying or gearbest

[satkingno]

why you want to use this? the box has LAN Port!

Yes, but not GB LAN right? Will 100M be enough for even the highetst bitrates? Im a noob, sorry

So with Mod done above
http://freaktab.com/forum/tv-player-...661#post684661

New spaced out LID ( raised by using plastic washers)



If you're in a tropical area a Fan or Laptop cooler underneath is the go if heat is a Big problem,
Often with Factory Rom, Junk in the trunk running in the Background is the Killer.
Or Kodi with lots of Addons (can be Evil)

Where does the fan get it's power from?

[P.X]

Could use USB pads I think.
No, drat it, they aren't switched. I don't think a constant fan would be good.
Have to find somewhere else ... Fingers crossed.

I'll try to do a vid/pics as and when possible...?

[clarkss12]

5V Input socket - Easier to solder pads are on underside of the board.
Could use USB pads either as an alternative.

A video would be nice.

A video would be nice.

Hi, see above edit... Have to find a nice switched supply ???

No switched supply that I can see (anyone know better ? let me know).

So I have changed to a silent fan that runs all the time, This is the 5V Pi Fan running at 3.3V with an isolation switch fitted to stop it, as and when.
Power is taken from the 3.3V UART +/- pads through a sub-minature slide switch mounted on the right flank of the box.
Fan is fully silent - 4x rubber sticky pads (made from 3M Double Sided or Generic foam tape) mount the fan to the lid and provide air-flow gap.
Lid attaches with a 2-3mm air gap around the edge.

Power consumption is miniscule.

Please can you take photos of the mods you have done? I'm interested to do the same but I am a novice. I think photos can help me and other users too.

For now I'm testing it with an external usb powered fan to check if the freeze depends on high temperature. If yes I'll try to install an internal PI fan.

Thanks in advance.

I tried 2 Slots in the lid - 4 / 6 would help, but none also works if you don't want the work. Takes a while with a Stanley knife ........
You can just see the 2mm air gap at the edge

Tap 3.3V from the UART Pads - Route Red +ve wire through a Sub-Miniature Slide Switch

Overview
Stick fan to Lid - Small squares of 3M (Generic) double sided foam tape 15mm wide
Double thickness works best.
Neg and +ve from switch - I just tinned the ends and inserted into the red PI plug.
Two pieces of double sided tape hold them in place (leave the red backing on)

Moved the Wi-Fi aerial to the side position - could put it back on the lid if you want.

Is it just me or does it seem ridiculous that we have to modify a Brand New box ourselves so that it functions properly?

[trebor]

Yes it is silly, but its what we do, Most can get by with a laptop cooler or just a small fan underneath.
And sometimes they take things on board, its built to a price.
