Tindie

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.

I love the product? it's the perfect solution for my project

I do li-ion powered G-scale locomotive with remoote control. The brains of the loc is Espruino. The choice of Espruino is explained by:
- javascript, as I'm non profi-programmer but I do know JS and NodeJS and all my other systems are based on NodeJS
- Wifi on board
- arduino-like, with lot's of supproted modules
- good support from the web-site
- asynchronic languge (JS), I suppose it's the best solution for running different tasks simultaneously

And with exception that I killed two boards due to inproper wiring the board itself is quite stable.

Amazing tech!

For Puck.js cases (Red, Yellow, Green, Blue)

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

Stephane | Oct. 14, 2017

Perfect add-on to Puck.js

Same high quality cover as the original Puck.js case. Comes in 4 colors. Note that this includes only the soft silicon cover that comes at the top of the case, not the hard plastic back that is part of the original Puck.js device. Recommended.

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

Stephane | Oct. 14, 2017

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.

GREAT Board !

For Espruino Pico (pinned)

And GREAT also for beginners and Students !
Hope it become the new Arduino for microcontrollers!
Keep it up !

Joze | Aug. 17, 2017

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.

Oleksandr | Aug. 14, 2017

Good quality

Fast delivery, good quality, nice to have at least simple instruction in package. Trying different cases and lessons espruino web-site.

Emilien | July 19, 2017

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

Laura | July 5, 2017

Useful board in compact format

The product itself is really nice, a compact format board, headers soldered already, perfect for breadboard use, but the documentation and the work around it Gordon has done is what makes it. There is no messing around with software & firmware updates are painless.

Dave | May 15, 2017

Perfect microcontroller for anyone who knows JS

Gordon has made something really amazing here.

Perfect for small projects, and even suitable for larger ones if you can think your way around some problems.

Great support from Gordon on the forums.

Kevin | April 3, 2017

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

Phil | Feb. 25, 2017

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.

An amazing technology: Espruino

Espruino Wifi (and also Pico) is THE awesome technology for embedded devices. Once you have started to use it, you understand that you will achieve incredible connected objects. Great documentation and service. Fast shipping. The technology that helps me achieving many projects in short time. Thank you Gordon.

Markus | Oct. 5, 2016

A+++

For Espruino Pico Adaptor Pack

Trusted source -Espruino from Gordon Williams - and convenient and helpful distributor - Tindie. Not the first time and for sure not the lat one returning to Tindie's.

Markus | Oct. 5, 2016

A+++

For Espruino Pico WIZnet W550io Ethernet Shim

Trusted source -Espruino from Gordon Williams - and convenient and helpful distributor - Tindie.

Note to everyone and every what ever smallest coin there is pincher: Never ever buy version 1.0... EXCEPT from Gordon Williams.

Braydon | Aug. 8, 2016

can be used as a 0.05 to 0.1 breakout

I thought I should leave a review here because the shim worked for what I bought it for, even though that wasn't it's intended purpose. Just cut the long parts off using a small pair of side-cutters. Then place the shim between the plastic of the header pins and the Pico itself, then solder the headers as normally installed on the Pico. This allows you to add 8 more 100 mil (0.10") header pins face up for use with a breadboard and male to female prototyping wires. And now you can make use of those tiny pins that looked unusable previously.

Great interaction

For Espruino Pico ESP8266 WiFi Shim

He did great! Shims worked, he was communicative, and they shipped from the UK to NYC in less than 7 days.

Sorin | Jan. 25, 2016

Shims are great.

For Espruino Pico ESP8266 WiFi Shim

At the form factor that it has the shims are awesome fro extending my espruino pico project with the famous esp8266 wifi module. Soldering was a little tricky but with the help of the video tutorial I got it on on no time.Apart from that everything seems to work ok.

Sorin | Jan. 13, 2016

Just love the Espruino pico.

For Espruino Pico (pinned)

Thx for the quick delivery. The product is great, the tutorials are great. The shims work perfectly with the ESP8266 WIFI module. I can say that I am very pleased with the results.

Austin | July 15, 2015

Must have for JavaScript lovers!

For Espruino Pico (pinned)

Not that I "hate" C and it's successors, it's just that I am lazy and I hate the extra work that goes into those frameworks. So I guess I hate them.
Especially as a web developer that prefers node, I feel right at home programming things with JavaScript which leads to a lot more fun with the project and a lot less debugging. Not to mention I can now steal straight from my existing code bases!
Winning!

Gonzalo | June 28, 2015

Great board!

The Espruino Pico is an amazing board, tiny and super flexible. We had an issue with shipping because I moved in between order and shipping, but Gordon contacted me as soon as he got the product back and shipped it back to my new address in no time.

Marten | June 22, 2015

All good

These are great! I'm a web developer without prior experience of microcontrollers and had an Espruino webserver up and running in a few minutes. If you know JS you can do almost anything with these. Review Image

Mario | June 17, 2015

Exactly described, fast shipment - TOP!

I ordered 2 Espruino Pico with slight cosmetic damage.
I got instant feedback on order and shipping status - shipping to Germany took a couple days but was fast!

The devices came softly packed with all Pins secured by some foam.

Using it on a Mac was fairly easy ... downloading the Espruino Web IDE from the Chrome Web Store, plugging the Pico in the USB and immediately could run through the in-IDE-Tutorial to make it blink :)

Thats how you get people hooked. No Drivers, no complicated install, and a fitting real example tutorial walking you interactiv through the IDE and the device programming.

Thanks!
Mario

Thomas | June 11, 2015

Smallest js computer

I am impessed by the size and seamless working with the espruino ide. Will inspire me on my way to js mastery.

David | June 11, 2015

Lowest TTFHW ever

I established my new TTFHW (Time To First Hello World) personal record: 30 seconds. Forget Arduino, this cutie is way more powerful and easy to use.
Shipment perfectly in time.

Frantisek | June 11, 2015

Espruino Pico is my darling...

Fast delivery, function OK... discovering of new things is exciting.
Very nice and challenging toy :-).

Jan | May 29, 2015

Awesome little board

An excellent little board. Things I like about it:

- Very easy to get started (Chrome GUI and the tutorials are quite nice).
- Programming it seems event driven, so it's almost like a RTOS. While I'm not a huge fan of javascript and levels of nested callbacks, it's actually quite fun to think about embedded projects like this.
- The cosmetic damage is really just that - cosmetic. I wouldn't even notice if I wasn't told.
- I like the option to solder a mini or a micro USB connector. USB-A is not always so handy when it's not being plugged right into a computer.
- It's really really small.

So - so:
- It comes with pins already soldered - which is fine for a breadboard fun, but not so much for an actual project. (For a battery powered project I'll anyway need to wait until the deep sleep can go really deep and turn off USB :)

Tatu | May 28, 2015

Great little board for your next IOT project :)

Got a little damaged during shipping (it seems someone at royal mail decided to leave my package at the bottom of the stack and load a ton of bricks on top it so the pins were bent. No problem bending them back straight tho). (Raelly there must have been a ton of bricks on top as the packaging was pretty good).

Getting the lights blinking took about 2 minutes (if you are on linux remember to give yourself access to the serial port ;)

Now I just need the next killer IOT idea (and maybe the wifi module and the shim for it.. and the battery.. and lots of other cool toys ;)

Jürgen | May 26, 2015

Awesome product and very kind communication
