With Halloween coming up, I figured this was a good opportunity to use my Red Pitaya board and Visual Programming to create something scary – I wanted a pumpkin, with flickering lights, that made a LOUD noise, triggered by movement.

Getting started with electronics is way more fun and interesting when you have a load of sensors that you can put to good use straight away.

The time has come for my first experiment with Red Pitaya’s Visual Programming. I will be attempting to make an LED on the board blink on and off at ½ second intervals.

This is an experiment you should only conduct very late at night. Only when you manage to wake up your entire family and get some local dogs howling, will you know that it has truly been successful.

Are you as paranoid as I am about people searching through your bedroom? Probably not. But this is still a really useful experiment to do. Especially when we begin to combine it with the other experiments in the next section.

This example is a combination of previous examples and also introduces functions.

Introduction to new release and software improvements

You might have been asking yourself what is happening at Red Pitaya? I hope you don’t think we got lazy. We have been “quiet” in the past 6 months regarding new SW releases because we have been making multiple improvements. This task has been so extensive that the only option was to bring it out in one go.

With this example you will learn about:

• Transmission line fundamentals
• Reflections on transmission line
• Red Pitaya SCPI commands

With this example you will learn about:

• EMC radiations and regulations
• Quantitative estimation of magnetic radiation
• Design and evaluation of simple analog filters
• Using Red Pitaya in combination with other circuits
• Difference between household appliance and outside devices

We had to try the LCR meter – ad hoc.
