Tutorials – Eagle Tutorials from Around the Web

I have used many schematic/PCB capture applications and I find that Cadsoft Eagle seems to be the standard for hobbyists.  As such, there are some peculiar features that takes some getting use to.  For instance, the user interface does not function like many point-n-click applications.  You can Google eagle tutorials and find plenty.

 

 

Below are some of my favorites:

Parts – DC 12V 2A Switching Power Supply Transformer

Here is another parts post for a 12V @2A switching power supply. This unit is small and has an aluminum case with cutouts for mounting. I used this power supply in my Reflow Controller project.  You can find it on ebay here (link will expire) or search for a DC 12V 2A Switching Power Supply Regulated.  You will more than likely get multiple results.

  

  

Parts – DC 5V 2A Switching Power Supply Transformer

Most of my projects require some type of power source. Now, I could go the DIY route and build my own power supply or I can do a search on ebay and find what I am looking for already finished and ready to go. Here we have a Minghuada MHD-10VA switching power supply that accepts 110-220VAC and outputs 5V @2A. This unit is small and has an aluminum case with cutouts for mounting. You can find it on ebay here  (link will expire) or search for a DC 5V 2A Switching Power Supply Regulated.  You will more than likely get multiple results.

  

  

Projects – Hobbybotics Reflow Controller V8.03

A while ago I decided to start designing my circuits using Surface Mount Devices (SMD).  There are many advantages to using SMD components over through-hole components.  Some of the major advantages are size and cost.  The smaller size means I can make the circuit boards smaller.  In addition, smaller components and smaller circuit boards means lower costs.  One of the disadvantages to SMD components is they are more difficult to solder than through-hole components.  The solution is to use what is called a reflow oven.  The following project details how I designed and built a reflow controller based on a MAX6675 Thermocouple interface and use it to control a common toaster oven in order to reflow surface mount circuits.  Check out the project here.
