PIC Prototyping Platform – PR2

September 7th, 2011 No comments

Hey,

In PR1¬†project, I talked about creating a stable prototyping platform that would save me from the trouble of setting up the microcontroller and all its required components. However, since then, I worked on tidying up this design into a more usable design (I wanted to play around with creating PCB actually ūüėÄ ). So I designed the board sent it for fabrication¬†and finally put it together. Read more…

Components for the Prototyping board arrived!

September 1st, 2011 3 comments

Hey guys,

A couple of days ago, the components for my new PCB arrived so I was able to test my design. The result was successful! Personally this was a simple board carries a lot of “firsts” for me. To begin with, it was the first time I ever designed a board on EAGLE that became an actual PCB. This might sound stupid but its different to make a design for home production (using chemicals) and a design that includes 2 layers, vias, solder masks, silkscreens, correct drill holes etc. I am not saying its hard, I am just saying its different so there are new things to consider.

Another “first” was the soldering of a TQFP package which as it turns out its not that hard (actually its like magic ;))! I had to buy some solder paste and a tweezers to make my life easier. I am suggesting to check out Surface Mount Soldering¬†guide if you are interested.

Anyway, for a first attempt, I believe the results are pretty good. I made a simple blinking LED program which works, the power switch and reset button work, so I am assuming the design is OK.

I will make another post soon to include the schematics and stuff if anyone is interested and hopefully start producing some projects on this proto board. Finally here are a couple of pictures of the board:

Looking good!

Dimensions are 5cm x 5cm

Low Cost PCB Fabrication

Hey guys. I am really excited today because my first ever PCBs arrived from the fabrication house! I always wanted to have my own PCB printed but I was deterred by the price. So I used other methods such as developing my own board which can get quite messy or just sticking with the traditional prototyping boards. Few weeks back, I read a post¬†from Kenneth, which led me to this fabrication house. They actually offer 10 PCBs maximum sized 5cm*5cm, for only $9.90 and $4 for delivery! This is really really cheap! Read more…
