A Smart Bluetooth Button that can be programmed wirelessly, in JavaScript!

Sorry! We're no longer selling on Tindie. Please check this out on the Espruino Shop Puck.js v2.1 - now with accelerometer, gyro, and calibrated temperature This comes with a black semi-transparent …

Why did you make it?

Writing software for embedded devices is hard, and it's even worse when they're wireless. I wanted to make something that made it easy to create wireless devices.

What makes it special?

You can get your own code working on Puck.js just a few seconds after getting it out of the box. With Web Bluetooth you don't need to install any software on your computer - just go to https://www.espruino.com/ide/ with a Web Bluetooth capable browser and you can connect instantly and start writing code. There's even a graphical programming language if you're not happy writing JavaScript.

Great Device!

This is an amazingly designed little piece of technology. I will definitely be purchasing more. Elegantly constructed, and great functionality. Gordon is brilliant, and has done a great job implementing ecmaScript on hardware this way; truly inspiring.

The only snag has been the unfortunate conflict when broadcasting advertisements that it blocks the process for being able to connect and edit the code for the unit -- but this is a natural outcome of the circumstances involved. I do believe it can be improved, but users should be aware of the potential stumbling block.

Excellent product, old firmware, wish for micro-USB connecto

Well designed product and the Espruino IDE results in a fast and efficient workflow. My main complaint is that the product was shipped with an old firmware and was basically useless prior to being updated. Once I found a video clip on YouTue on how to update it worked nicely with my Chromebook.

I couldn't get it working with my Windows laptop however and because of that I would have preffered to have a micro USB connector on the puck.js. That would hopefully also make it easier to work with BLE as you then could use the IDE for programmnig without interferring with Blueooth.

Despite this I still think this is an excellent little device.

Brilliant

Exactly what I needed. Arrived immediately. The community has already helped me a great deal as a newbie to this world. Bravo.

Amazing tech!

Extremely fast and safe trackable shipment, very good quality, nice documentation and amazing support!

Recommended for Makers

Very small device, perfect for JS based projects. The Puck.js comes with its battery, everything fits in "the button", and can be programmed remotely with BLE. Simple to use, powerful, and autonomous. Recommended.

On top of the product, Gordon Williams is reactive and very helpful in case of questions or issues.

Got it, opened it, programmed it :=)

It's amazing how well the the quick-start went and how quickly I had a simple program running on it. I plan to use it as a home automation "anything" sensor.

An amazing piece of electronic

It very simple to use it
The only limitations are your imagination and the devices that can connect to it, but you can go very far with it

I love the Puck-JS

The Puck-JS is a great tool for some simple introduction to programming and robotics. But it can go beyond the simple.

I think it would be a great device for classrooms as well as hobbyists.

Terrific

Fantastic, simple, open and programmable BLE device

Puck.js is fantastic! I'd have never thought that it was possible to write a few lines of Javascript and have a piece of hardware that can talk to my Android phone over BLE. The best bit is that every aspect of the behavior is programmable, and in Javascript to boot.

I've even found myself paring it with the Android tablet and hacking on ideas while on the train--the programming environment runs on tablets too, so it is really easy to carry a basic hardware hacking toolkit around.

Espruino puck.js is ... great

What is great?
- the feeling that I have a zx80 and the kick I had when I first played with onboardbasic: now on steroids with onboardjavascript and the physical world at my fingertips.

In the palm of your hand, a nice shape: what do you want to use it for? Your own imagination is your boundary: it won't make your tea, but as it has a temperature sensor (on chip) it can certainly tell you if the contents are too hot or cold.

So, look at the Espruino logo, and make your first cup of tea, monitored by a puck.js with green yellow and red lights to indicate temperature.

With a puck.js, you don't get burnt.
