Arduino Flame Sensor….. could use this to check that the flame is still lit on the 3-way fridge in the van?
These look worth taking another look at…
This is the sound system for the back of the van….
OK…. so I like tinkering and I started off with some 12V computer speakers that I could plug my MP3 player / Laptop / Phone into. That works fine enough and because I found some free ones that worked I never bothered sorting anything else out.
Then I decided that I wanted the option of a little a little more oomph! …and what the hell, why not make it myself.
This is a great source for answers to stupid questions http://www.diyaudio.com/
This is a link to the board I went for in the end [Edit: should have gone for something with even more oomph!]
……………..poo can’t find the link!
The idea is to find a nice piratey looking box to mount all of this in. I can also use an old laptop power supply to either power this or to power everything 12V!
This is the board that I got…. its surprisingly small for so much umph!
Here is the random car-boot-sale mini pirate chest that I managed to pick up for 50p
First half done…. the walls of the box were too thick for the controls and connectors to poke through.
So I cut a bigger hole and mounted a plastic plate on the inside which the control and connectors poke through.
The next step is to do the same again on the other side for the power and speaker connectors. You can just about make out the air holes drilled in the back of the box. Hopefully this is enough to stop it over heating but I’ll have to run it for a while to find out.
So I have ordered some panel mount dc power sockets…
…and some speaker connectors…
The finished article
…so I went back and cleaned up the wiring a little as well!
The N40L comes with 1 × 2GB ECC RAM installed. It will accept up to 16GB (2 × 8GB) 240-Pin DDR3 SDRAM 1333 (PC3 10600) RAM  [Does this apply to all Gen7s?]
Non-ECC RAM is compatible, but not recommended for mission critical servers. Most casual, NAS or home server systems do not require ECC RAM.
Does not support registered (buffered) modules. Using registered modules will result in the server failing to POST/boot. (‘blue light’).
Capable of utilising dual channel RAM, which results in marginally increased memory speeds when two matched DIMMs are installed.
Ensure that RAM modules do not have large heat-sinks protruding from the top (clearance approx. 40mm from slot to chassis).
