# This week on tech #2

The last time I went running in Jurong, I was given an RFID tag and later on my timing was published on a website. I had some theories on how they could have done this until I landed this site recently. So if you plan to host a running, then you might want to read this link!

And then I came across another link to build a  IoT oscilloscope for $25. Reading on, I think more than the scope, I love the idea of getting a$20 board that I can play with. Surely in my to buy list in the next set.

I always wanted to build an arduino clock. I have never gotten myself to sit down and do this actually. But I keep hoarding links in this direction. Here is one more on building an NTP server!

I always believed that getting a doorbell notification on the smartphone was expensive technology. Read this link to debunk this myth!

This is how you could build a bicycle computer and this is how you could build a non-invasive tachometer.

On robotics, I came across this interesting link where we could build the chassis using PVC pipes. Good one and will be trying it one of these days.
