Here’s a worthwhile Kickstarter for once: the Prishtina Hackerspace. Yes, that’s a Kickstarter for a hackerspace in Kosovo. Unlike most hackerspace Kickstarters, they’re already mostly funded, with 20 days to go. If we ever get around to doing the Istanbul to Kaliningrad hackerspace tour, we’ll drop by.
Codebender is a web-based tool that allows you to code and program an Arduino. The Chromebook is a web-based laptop that is popular with a few schools. Now you can uses Codebender on a Chromebook. You might need to update your Chromebook to v42, and there’s a slight bug in the USB programmers, but that should be fixed in a month or so.
Here’s a great way to waste five minutes. It’s called agar.io. It’s a multiplayer online game where you’re a cell, you eat dots that are smaller than you, and bigger cells (other players) can eat you. [Morris] found the missing feature: being able to find the IP of a server so you can play with your friends. This feature is now implemented in a browser script. Here’s the repo.
The FAA currently deciding the fate of unmanned aerial vehicles and systems, and we’re going to live with any screwup they make for the next 50 years. It would be nice if all UAV operators, drone pilots, and everyone involved with flying robots could get together and hash out what the ideal rules would be. That’s happening in late July thanks to the Silicon Valley Chapter of AUVSI (Association for Unmanned Vehicle Systems International).
SOLAR ROADWAYS!! Al Jazeera is reporting a project in the Netherlands that puts solar cells in a road. It’s just a bike path, it’s only 70 meters long, and it can support at least 12 tonnes (in the form of a ‘fire brigade truck’). There’s no plans for the truly dumb solar roadways stuff – heating the roads, or having lanes with LEDs. We’re desperately seeking more information on this one.
A few weeks ago, we saw codebender, an online replacement for the Arduino IDE that allowed you to upload a sketch to your board from a web browser. Over on the codebender blog [Vasilis] and his team are rolling out a way to remotely upload code to an Arduino over Ethernet. Now you don’t even need a serial connection to program an Arduino; it can be done over the Internet to a board in the next room, or on another continent.
The star of this hack is the Ariadne bootloader, an implementation of TFTP that allows any Ethernet-enabled Arduino to receive updates over the Internet. There is still one small problem with the Ariadne bootloader: uploading code over Ethernet requires someone to press the reset button on the Arduino, completely negating the benefits of programming an Arduino over Ethernet.
This problem has been solved before for earlier Arduino boards, so we’re sure [Vasilis] and his team will be able to fix the reset issue in very short order. If you’d like to check out the remote TFTP bootloader and play around with codebender, you can grab Ariadne over on GitHub.
Because everything is moving to a web app, [Vasilis Georgitzikis], a.k.a. [tzikis] developed codebender, a cloud-based Arduino IDE replete with built-in libraries, documentation, and the ability to upload your code to an Arduino from a browser.
To compile an Arduino sketch, codebender uses clang a wonderful compiler that will give you extremely descriptive warnings on terrible code. Like any good IDE, there’s built-in highlighting and documentation, and a small bit of Java allows you to upload your code and monitor the serial port right in the browser.
One of the more interesting innovations is codebender’s (upcoming) use of a TFTP bootloader. With this and an Ethernet shield, it’s easy to upload code to any Internet-connected Arduino, whether it’s on your desk or halfway across the world. We can see that being very useful for a data logger or even a UAV balloon, and can’t wait to see it in action.
