Death Generator Makes Game Over More Personal
“Game over”. In this day and age of complex games with storylines and career modes that last for tens of hours, it’s not really a concept that has a lot of relevance. However, in the golden age of the arcade, those two words made it very clear that your time …read more

Arduino Enters the Cloud
Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.
The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can …read more

Hack Your Gmail: A Quick Start for Google App Scripting
For many people, Gmail is synonymous with e-mail. Some people like having cloud access to everything and some people hate having any personal data in the cloud. However you feel about it, one thing that was nice about having desktop software is that you could hack it relatively easily. If you didn’t like how your desktop mail client worked, you had a lot of options: use a different program, write your own, hack the executable of your current program, or in the case of open source just fork it and make any changes you are smart enough to make.

Delicious Vector Game Console Runs Pac-Man, Tetris, and Mario
The only question we have about [mitxela]’s DIY vector graphics game console is: Why did he wait five years to tell the world about it?
Judging by the projects we’ve seen before, from his tiny LED earrings to cramming a MIDI synthesizer into both a DIN plug and later a USB plug, [mitxela] likes a challenge. And while those projects were underway, the game console you’ll see in the video below was sitting on the shelf, hidden away from the world. That’s a shame, because this is quite a build.
Using a CRT oscilloscope in X-Y mode as a vector …read more

Nim Writes C Code — And More — For You
When we first heard Nim, we thought about the game. In this case, though, nim is a programming language. Sure, we need another programming language, right? But Nim is a bit different. It is not only cross-platform, but instead of targeting assembly language or machine code, it targets other languages. So a Nim program can wind up compiled by C or interpreted by JavaScript or even compiled by Objective C. On top of that, it generates very efficient code with — at least potentially — low overhead. Check out [Steve Kellock’s] quick introduction to the language.
The fact that it …read more
Turning That Old Hoverboard Into A Learning Platform
[Isabelle Simova] is building Hoverbot, a flexible robotics platform using Ikea plastic trays, JavaScript running on a Raspberry Pi and parts scavenged from commonly available hoverboards.
Self-balancing scooters a.k.a. Hoverboards are a great source of parts for such a project. Their high torque, direct drive brushless motors can drive loads of 100 kg or more. In addition, you also get a matching motor controller board, a rechargeable battery and its charging circuit. Most hoverboard controllers use the STM32F103, so flashing them with your own firmware becomes easy using a ST-link V2 programmer.
The next set of parts you need to …read more
TensorFlow in your Browser
If you want to explore machine learning, you can now write applications that train and deploy TensorFlow in your browser using JavaScript. We know what you are thinking. That has to be slow. Surprisingly, it isn’t, since the libraries use Graphics Processing Unit (GPU) acceleration. Of course, that assumes your browser can use your GPU. There are several demos available, include one where you train a Pac Man game to respond to gestures in your webcam to control the game. If you try it and then disable accelerated graphics in your browser options, you’ll see just what a speed up …read more
A Wrencher On Your Oscilloscope
We like oscilloscope art here at Hackaday, so it was natural to recently feature a Javascript based oscilloscope art generator on these pages, along with its companion clock. Open a web page, scribble on the screen, see it on the ‘scope.
As part of our coverage we laid down the challenge: “If any of you would like to take this further and make a Javascript oscilloscope Wrencher, we’d love to make it famous“. Which of course someone immediately did, and that someone was [Ted] with this JSFiddle. Hook up your soundcard’s left and right to X and Y …read more
Running Programs On Paper
It’s a simple fact that most programs created for the personal computer involve the same methods of interaction, almost regardless of purpose. Word processors, graphics utilities, even games – the vast majority of interaction is performed through a keyboard and mouse. However, sometimes it can be fun to experiment with alternative technologies for users to interact with code – Paper Programs is an exciting way to do just that.
Paper Programs is a combination of a variety of existing technologies to create a way of interacting with code which is highly tangible. The setup consists of a projector, and a …read more
