Well, the schematics are up there - you could do an approximate BOM cost yourself. Prices are going to vary whereever you are in the world, so you may as well check it out from your local distributor. The PCBs were cut rate from Dirty PCB - they were about $20 for a batch of 10, so about $2 USD each. The wood for the box was scrap. You already know that the top plate is about 100 bucks, but if you have access to a CNC machine you could probably drop that to about a third or less.
If you're going to be an engineer, you should be able to work out a price on your own.

Hi folks,
It was a nice day yesterday so I was outside working on the box. I routed the outside corners and it all looked good. Time for hardware!
So I was looking around for a pair of detachable hinges, and I found these at Lee Valley:
http://www.leevalley.com/en/hardware/page.aspx?p=45246&cat=3,41241
Unfortunately when I went around to the store/warehouse I found out that they are really tiny. Like jewelry box sized. A search didn't turn up anything else, so I went 'round to Canadian Tire and grabbed a pair of hinges with removable pins and proceeded to make my own.
The first step is to cut a slot in the middle bit with a hacksaw. You need removable pins so you can separate the pieces:
After a little bit of shaping with a file, the other side could slip in and out easily:
Once that was done, I somehow had to fix those loose pins in place. I used my drill press and a #53 drill to carefully drill 1/4" deep holes in the end of the pins.
Then I inserted them into the hinge plate, grabbed a punch and gave it a solid whack - which mushroomed out the end fixing it in the hinge plate.
Box is enclosed and the lid lifts off with no problem!

After that was all done, it was time to put the electronics in and see how it worked overall.
The plan is to have the unit mounted on a mic stand for easy tweaking, so I put one of those female end mic sockets in the bottom.
Seems to work pretty well!

Very well done! As Rgand pointed out, mic stand socket is a terrific idea. Nice... :icon_thumright:

How are you mic'ing drums? Kick only or overhead? I'm all for minimalist micing of drums, but minimal is typically bass drum if there's only one mic, and 2 is still "minimalist"
