What do you do when you are asked to entertain kids (8 to 18) in a summer boot camp at an AWESOME Technology Incubator.

You bring what you LOVE to the table - what we @EjaadTech love is MAKING and Electronics.

So, after thinking about it and asking here, we went for JUGNU, LED Throwie kits for kids.

This is a LOG of what we did and the relevant files and images.

The project is our story of how we gave some kids their first entry into electronics and making by showing them how make an LED Throwie - do check out the project images and the logs and the Files attached with the project.

I used any and all relevant images/material/diagrams I could find from Google - without giving attribution/credit to anyone or even asking about it. SORRY FOR THAT - but this is just a small project and no commercial stuff - so i hope no issues. :)

A great idea. Some very basic electronics to get the kids interested to begin with. It's too easy these days to just open a box and play games. Getting hands on is a great way to break that cycle:-)

Now, thinking what to do next time, we will have a NEW batch of kids and the kids in the first batch said, it was too easy, so maybe something a bit more difficult/challenging.?
