Finished One Storage Cabinet

Yesterday, I finished sanding the workbench storage cabinet. After assembly, the doors did not quite close., but I managed to convince them by using a belt sander.  I just need to go over it one more time with the black primer paint, and it will be done.  The total cost for both of the cabinets is about $55 (not including the paint or glue).  The peg board hooks were another $8 for 50 pieces (which does one cabinet) (Harbor Freight Tools).

I have all the parts cut for the second one which will be mounted to the right of this one... I hope to get to it in the next month.

The doors are kept closed using cabinet magnets shown below ($0.75 from Home Depot)

Cabinet Latches
 I also bought these handles from Home Depot for $2.00 each.

Completed Circuit Card Assembly (CCA)

Last week I recieved the surface mount PICs from Digi-Key (Part Number: PIC16F688-I/SL).  After soldering the PIC into place, I plugged my 'PICkit 2' into the CCA and powered it up.... SUCCESS!  It worked the first time (meaning, the programmer recognized the chip and I did not let out any of the magic smoke).

Completed CCA

This was my first attempt at soldering a surface mount component.  It was far easier than I anticipated. 

The code, however, is far from complete.  There is a lot of seemingly random movement of the RC Servo.  I have created a few lines of code which add in a 'dead zone' to stop the movement... but I am not getting the full travel of the servo (which should be about 180 degrees).  I think the issue is the conversion between the ADC output value and the servo input value.

In the next week or two I plan on figuring out what is wrong, and hopefully get both servos operational.

New Addition to the Garage

The CNC router has been placed on my workbench awaiting the motors and other electronics.  Check out the Pro-E model of the garage!

The CNC Router will be on the right off the workbench with the computer sitting next to it.  I have not yet added the right rack or workbench.

I will hopefully be buying the motors to complete the CNC Router in the coming months.  I plan on buying them from Keling Technology Inc, but as you can see from the below, its a large hit to the wallet.

Finally, I have started to design storage units for the wall, just above the workbench surface (shown in the Pro-E model above).  The front and rear panels of wood will be peg board to hang tools.  Luckily the wood is cheap, so I should be able to build these soon.
