It's a straight forward kit that lets you build an MPLAB ICD2 compatible Programmer and Debugger.
There are lots of Programmers out there but very few include a debugger, (A debugger lets you single step through your program and set watch lists (see your variables) and much more).
The full manual including schematic and notes can be found at blueroomelectronics
Step 1: Preparing the PCB
Step 2: Solder all the "low profile" parts
Add the resistors first, noting the tan resistors are the common 5% tolerance versions and the blue resistors are 1% metal film types.
Now install the diodes, both the smaller glass diodes and the larger power diodes require you to pay attention to the colored band on the cathode of all diodes. Failure to install the diodes in the correct orientation will keep the Inchworm or any electronic project from functioning properly.
Note: I'm building a battery powered version for demos, the power diodes I used are low dropout Schottky 1N5817 types instead of the more common 1N4001 diodes. The six small glass diodes are common 1N4148 types (you can also use 1N914)
Step 3: More small parts added
When you solder an IC socket its a good idea to solder in only one pin on a corner to give you a chance to have it sit properly on the PCB. Once the socket is flush continue to solder the rest of the pins.
Next the bypass 0.1 uf caps are added, these tiny caps are important when using any logic IC, they are for absorbing little glitches with digital logic chips.
I've added 5mm LEDs instead of the 3mm specified LEDs. It's simply a matter of taste.
