I made this protoboard platform. It makes staging experiments easier.
There's lots of real estate inside the project box (Serpac 071BK).
I'll get around to placing some screw terminals and so on, lots of room still on the exterior surfaces.
I used the Arduino box to hold the Arduino because I don't like the Arduino's 3-hole mounting. It snaps smartly into the box.
I took pics with and without the top panel (lid). Things are more accessible without.
Nice 
Pretty cool looking, guys!
Very convenient for running the X10 Firecracker demo this morning, trucking around the house and so on (100%).
@dlloyd: good demo there, +1
@proto-pic, @crOsh: appreciate your notice
Can you put wires etc. in the base?
Would you post a X10 sketch?
I am having trouble get replacement modules for our X10 collection.
Have you experimented with Insteon products and X10 code?
.
"Can you put wires etc. in the base?"
You mean the black box that everything is mounted to? Sure. It's empty in there right now, but I have plans for putting stuff inside [#1, one those 'ubiquitous' 5V SMPS, a panel jack and a lead out; #2) a couple of pushbuttons, and then...]
Here's my X10 sketch, just turning on/off...
I got the X10firecracker.h from Arduino Playground (as I recall) and the Firecracker modules from ebay just before Xmas.
#include <X10Firecracker.h>
void setup()
{
X10.init(11,12,1); // rts signal, dtr signal, bit delay
// RTS is DE9 pin 7,
// DTR is DE9 pin 4
// DE9 pin 5 is GND
// interface w/ C17's DE9-F
pinMode(13,OUTPUT); // concurrent with on/off command
delay(1500);
}
void Test()
{
X10.sendCmd(hcA,7,cmdOn);
digitalWrite(13, HIGH);
delay(5000);
X10.sendCmd(hcA,7,cmdOff);
digitalWrite(13, LOW);
delay(5000);
}
void loop()
{
Test();
}
I know nothing of Insteon.
Thank you for your sketch.
I have not used Insteon, but have been told their modules accept the X10 protocol.
Would have been nice to have had the room under my unit to store wires and a power supply

What is the source for the clear Arduino box?
I made this front panel to a breadboard setup a while back.
Might want to consider a removable version attached to the back/front surface of your mounting box.
.
"What is the source for the clear Arduino box?"
This is the exact one --
Complete with light pipes 
Thanks.

Made a digital thermometer this morning:
• LM34 temperature sensor
• charlieplexed BCD display
Tells me it's 74
Neat
I like DuPont connectors.
As used for some WS2812 test & eval recently.
Maybe you can make out the terminal block I've placed (but still not using, thinking).
Gone over deep into 'The Great Relay Board Mystery' --
