Awesome Resource on PIC ASM

I have recently been working on a project that requires me to return to Microchips Pic Assembly Suite. Having worked mostly on Pic C18 for a while, it was a little difficult to program in assembly again. After a couple minutes of research on the web, I found an awesome resource for Pic hardware and assembly.

Gooligum Electronics has very detailed information on various ranges of hardware complexity and accompanying assembly code to help use the hardware as well. This link will also be included in the useful links box on the right.

Cutting Open An Inductor

Ren cut open an inductor while soldering, and we found out that they actually contain a coil. Below is some inductors for comparison and the unraveled wire from the cut-open inductor.

Using a LPKF PCB Mill


I operated a LPKF PCB mill for my first time last week.The board I made attaches to the back of my friend's AVR DB101 board. My board just adds an accelerometer to the unit.

The LPKF machines definitely have some bugs that need to be worked out. For example, you can see that the machine scrapes the copper when drawing the traces (picture 2). There were also some alignment issues that had to be worked out prior to milling it.

Although there were some bugs, if they were a little more affordable, I would buy a machine for myself. It definitely speeds up prototyping.
As you can see I made some mistakes and had to fix it using jumper wires.
