Electronics - Hacking the SX2 Mini Mill - (Adding a reverse switch and reverse engineering the tachometer port protocol)
Enclosures:
Here are some clever enclosures folks have made for the tachometer kit. If you have a tachometer enclosure you are proud of, feel free to email it to me and I'll post it here. For those who are preparing to make their own enclosures, the following dxf file of the board and hole positions may be useful:

Frank Hoose:
Frank of mini-lathe.com did a review of the SX2/CN2 tachometer. He also shows how he built a tachometer case for his lathe. It looks like it's part of the machine!
Colin:
Colin used a translucent blue Hammond box for their enclosure. This should really make the RPM digits stand out.
Mr. T:
Mr T. wanted an industrial look for his tachometer enclosure and came up with this carbon-fiber setup. He came up with a very cool hinge idea too!
Mark B. from Spring, Texas:
Mark B. found some enclosures at Frys (LMB Heeger LMB#650 - width 2-1/8, length 6-1/2, height 1-5/8) that were painted the same color as his machines. To cut out the display windows he used a nibbler and to make the digits stand out, he cut out sections of some inexpensive plastic boxes.
Eric of Rhema Machine Shop/WhiteStone USA:
Even made enclosures for their Lathe and Mill tachometers using a .308 cal ammo box and rifle ammo box (Case-Guard M/N-RM-50; 50 RND Rifle Flip Top; RM-50-24) respectively. Both enclosures can be had for under 3$!
