Which hardware, languages and APIs are used the most at hackathons?


Devpost ranked the APIs, languages and technologies that student hackers used during the 2014-2015 academic year.


Thanks to the burgeoning Maker Movement, the number of hackathons has surely risen in recent years. The next generation of programmers, engineers and designers all come together for a few sleepless days, fueled by pizza, Red Bull and coffee, to devise new and exciting gadgetry either of their choosing or based on parts provided by one of the sponsors. These weekend-long events organized by and for students are surging in size, scale and frequency, popping up in some of today’s booming tech centers ranging from Silicon Valley to New York. At hackathons, time is a valuable thing. This, of course, means that participants must strive to generate code and piece hardware together as quickly as possible.

11061272_1639114646317502_6597268336542950867_n

Which programming languages are the most popular? What has become the go-to hardware? Which APIs and platforms do people utilize most frequently? This is what Devpost —  formerly known as ChallengePost — sought to find out. In order to accomplish this, the online community and competition platform collected data and ranked the technologies and programming languages that student hackers have turned to the most throughout the 2014-2015 academic year.

Devpost examined project tags from a sample of over 13,000 student hackers who participated in 160 hackathons and submitted 9,898 projects, either in hackathons or on their Devpost portfolios. The technologies tagged in projects include languages, various APIs, frameworks, databases, IDEs, libraries and hardware, among several others. For each category, the company reported the top five tags.

While you can check out the entire report here, we’ve highlighted some of the more interesting findings below.

When it came to mobile platform, the crowd favorite was Android with 38.2% followed by iOS at 22.7% and Windows Phone at a distant 4.9%. As for programming languages and frameworks, HTML and CSS topped the list with JavaScript, Python, Java and C/C++ not far behind. Outside of the top five included PHP, Objective-C, C#, Swift, JSON, Ruby, XML, Ajax, Shell and Processing.

devpost_student_programming1-1024x541

In terms of hardware, the easy-to-use Arduino unsurprisingly found itself atop the leaderboard ahead of Myo, Pebble, Leap Motion and Oculus Rift. Other notables included Raspberry PI (#6), Intel Edison (#7), Particle (#9) and Tessel (#18).

The use of standard libraries and preexisting tools is paramount in getting a project up and running quickly. And so, many developers rely upon popular APIs and SDKs. According to DevPost, the most popular programs used by students included Twilio for messaging, Facebook for social, Venmo for payments, Google Maps for geo, Spotify for music and Unity for gaming. The rankings reveal that Node.js was extremely popular during the academic year, more so than app frameworks like Flask, AngularJS, Ruby on Rails and Django.

MESH is a DIY platform lets Makers create smart projects for the IoT


Hack the real world using MESH in just minutes. 


Designed by a team of engineers at Sony’s Seed Acceleration Program, MESH (Make, Experience, SHare) is a DIY platform that allows Makers to create their own smart projects.

20150108071655-Indiegogo_WhatIsMesh21

The platform is comprised of hardware building blocks of sorts that connect to each other via Bluetooth Smart and Low Energy, and contain software that can be programmed via a simple Graphical User Interface (GUI) to define a function. The Button Tag is used to make shortcuts or controllers, the LED Tag to create colorful notifications or lighting sequences, while the Acceleration Tag to detect motion patterns. The GPIO, or General Purpose Input Output Tag, is for advanced users and features digital and analog input/output that can sync other sensors or actuators such as light sensors, motors and written circuits with a conductive pen.

20150104105721-MESH_Intro1

MESH makes it easy, fun and convenient for anyone without engineering or coding skills to build their own inventions. In fact, the MESH Tags can be attached to just about anything, ranging from trash cans, closet doors and mailboxes. This enables Makers to design some innovative projects, like trash can that says “thank you” when someone disposes waste, a closet light that turns on when opened or a mailbox that sends an alert when the postman arrives.

20141229054818-Lchika

With the visual design app Canvas’ drag-and-drop interface and wireless functional Tags, MESH doesn’t require any coding when developing a connected objects. When pairing Tags, users simply move the corresponding icons for the Tags on the iPad app and draw a line between the two they wish to connect. There is also a SDK for those seeking more advanced customization, which provides developers with the option of writing their own software Tags to work with the MESH hardware.

In the future, the team plans to add other Tags including a thermo-hygrometer, IR receiver/transmitter, light and UV sensor, CO2 sensor, motion sensor, DC motor, and vibrator. It should also be noted that the team did mention that it made several prototypes using rapid prototyping tools, most notably Atmel based Arduino boards and 3D printers.

20141223131842-PrototypeHistory

The DIY concept behind MESH certainly represents a new theme emerging throughout the Maker Movement, as seen with earlier projects like BITalino and the WunderBar (whose team we had the chance to meet during World Maker Faire 2014 and CES 2015). Interested in learning more? MESH has launched an Indiegogo campaign, where it is currently seeking $50,000.

Dual port RAM interface debugs NES games

While writing a game for his old-school NES console, Andrew Reitano realized that live debugging on real hardware would definitely be a step up from the usual software-based fare.

The original solution? Firing variable information out the second controller port to serial every NMI. However, Reitano ultimately decided to take a shot at designing a new Atmel-powered PCB to interface with the console.

“The board routes the left port of the dual port RAM (Cypress CY7C136) to the DIP footprint on the NES and the right port to an AVR (ATmega164 MCU), this allows me to read and write any location at runtime without bus conflicts,” Reitano explained in a recent blog post.

“Control is provided through the UART and two additional pins are soldered directly to the 2A03 to control /NMI and /RESET. AVR control code was written mainly in C with some assembly sprinkled across for the memory control portions.”

The ATmega164 – tasked with “waiting” for serial commands – performs a number of functions including:

  • Read/write of any memory location
  • Quick dump of an entire 256-byte page
  • Freezing of memory addresses (rewriting a single value constantly in the busy loop)
  • Single frame stepping by controlling the NMI
  • Remote reset of console
  • Applying auto increment to tables to a single variable (fun for sine waves on x/y positions)

“[I] had pretty great results with using 250000 baud with the Genesis flasher project which is plenty fast for what I’m trying to do here,” he added. “As far as I can tell from the datasheet leaving CE low shouldn’t have an effect on the opposite port but it most certainly does. Next revision could definitely use a few pullups on the AVR side, other than that I’m pretty happy with the layout.”

Generating random numbers with an ATtiny45

A HackADay forum member by the name of Karl wanted a hardware-based random number generator. His two primary criteria? Keeping costs low and ensuring sufficient generation of arbitrary numbers.

The solution? Atmel’s ATtiny45 microcontroller (MCU), paired with a USB/serial converter, three wires and a DIP socket.

“Some projects either require expensive parts (geiger tube), are quite big (lava lamp), or are not random enough. Also most of the projects require some soldering experience, which can be a problem for newbies,” Karl explained in a HackADay forum post.

“I was not happy with the options I found. Luckily I stumbled upon the Entropy library for AVR’s. I checked the results from authors’s web site. I also did a few tests on my own by creating a 1mb sample of random data. I was pleased with the quality of the random numbers.”

As HackADay’s Brian Benchoff explains, the AVRentropy uses the watchdog timer’s jitter in AVR microcontrollers to provide cryptographically secure random numbers.

“Setting up the circuit was easy – an ATtiny45 microcontroller was connected to an [inexpensive] USB to serial converter. Three wires, and the circuit is complete. The code was simple as well; it’s just a call to initialize the entropy and write the bits to the serial port,” Benchoff added.

“There are a few drawbacks to this build. Because the entropy library must wait until enough entropy is gathered, it can only produce about two 32-bit numbers per second. That’s all Karl needed for his application, though, and with an enclosure made from a wine cork and marble, he has the prettiest and smallest random number generator around.”
