Once you've uploaded code, you can inspect and change variables (including functions!) while your program is running.
I was amazed at how difficult it was to get started with (and then to debug) most Microcontrollers (especially ARMs), and the lack of support for different platforms. I thought that by putting the development tools on the device itself I could come up with a microcontroller board that could be programmed easily from almost any kind of computer.
Not only that, but your source code is on the board itself. If you make something with an Espruino board and need to change it a year later, your original code is still there waiting for you!

We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I've been making things for as long as I can remember, and first programmed a microcontroller around 20 years ago. For the last 4 years I've been working full-time, supporting and improving both the Espruino firmware and boards.
