Here's my new M^3. Very unspectacular casing in the ubiquitous all black Hammond. I'll have to start getting more creative on the casing.

The component list is fairly standard with the exception of the Electrolytic caps which are Elna Silmic (330uf) and Nichicon Muse KZ (100uf)

I thought that I had made a mistake with the Elna caps. Because of their size I could only fit 6 x 330uf (total of 1980uf). I contacted AMB who assured me that it would be fine. After this I noticed that the schematic actually lists 2000uf for C7. So it was all good.

The M^3 certainly sounds the business.

Prior to this build I had built up a Pimeta, Steps and a couple of CMoys.

Simplicity can be very elegant, and your M3 is that, Fordgtlover.

Question - it looks like you drilled cooling holes in the side. I've always wanted to do that. Can you tell us how many and how big? I suppose that combined with the case lid contacting the heat sinks makes thing pretty cool.

fordgtlover, a black sharpie covers the raw aluminum vent holes in a fairly acceptable way...

Here are a couple of the vent holes. Since taking these shots I have spray painted the inside of the case, which leaves a much neater tiny silver ring around the outside edge of each hole. I'll post the last picture tomorrow.

If I decide that the little silver ring is still no good, I'll try the sharpie idea - thanks for that.




As Tomb noted, my case lid comes actually comes in contact with the heatsinks. This means that the whole case now dissipates heat. This, in combination with the vent holes, means that the case of my M^3 runs only slightly warm to the touch.

Thanks to Tomb for the very kind words regarding the elegance of my build.

Meanwhile, I need to find my next project. That is until the eagerly awaited Millett Hybrid MAX becomes available.

Action shots come when I figure out what exactly to put in front of the LED's.

I'm glad you like it! I did a lot of the layout, but I can't take much credit for the case since my father did all the construction and staining. As you might have noticed, he had to do a lot of recessing, because all the panel mount components were designed for thinner walls.

DIY Headphone Stand...

I built this for shop class, so most of this stuff was found around the shop. the base is 4" diameter, 1" thick stainless steel(S.S.). in the middle, a .5" hole was drilled and tapped all the way through. then a 10" S.S. rod was cut (.5" in dia) and threaded. i milled a flat spot on the top 1/8" deep, 1/2" down. i drilled a 7/32" hole (IIRC) in the middle of that flat section and stuck a hook (from home depot, the one thats 67 cents and has a yellow coating) in there, and since it had a wood thread on it, i trimmed it and epoxied it in.

Pics:

(dont mind the mess, i just did some rearranging and have yet to run wires)


my diy A47 amp to the left of my laptop



edit: hook might look crooked, but its just the pic angle, same with the headphones
