Homebrew PCBs

It’s the relay driving the heater (shown as a 12V lamp in the schematic).

As stated by other members posts, this is a single pole 12V relay. <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 

The schematic has been created with National Instruments Multisim Program - Simulation. Schematic capture and PCB layout package. <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 

In the Simulation (SPICE based) package various circuit paramaters can be altered  <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> "on the fly" while the simulation is running.

Using available real time instruments any part of the circuit can be probed and the results noted / plotted. <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 

The NIMultisim BLUE package is available FREE from Mouser Electronics Components. It comes with a basic component libary, all other  <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 


component libary parts can be added as real parts from Mouser as a multipart SPICE Package with Schematic symbol and the corresponding PCB <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 

Footprint. <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 

Be warned, this download is very large (well into GBytes) and requires time and patience to confidently utalise all of the package features  <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg> 


Hope this helps, chester <http://www.learnmorsecode.com/laminator/gbc/pp330.jpg>
