Join me on July 18th for Hackaday Prize Worldwide: New Delhi — a KiCad workshop, hardware show & tell, and a chance for you to meet other hackers and makers in the area.
Hacker spaces are on the rise in India, a development that really excites me. When I helped co-found India’s first, community Hacker Space – Maker’s Asylum – in Mumbai, things were pretty lonely. And this was less than 2 years back in 2013 November. Last month, we opened New Delhi’s latest, and the Maker’s Asylum’s second space. There’s already a couple of other hacker spaces in New Delhi, and you can now find hacker spaces in Mumbai, New Delhi, Pune, Bangalore, Chennai, Cochin, Meerut, Kolkatta, Surat, Ahmedabad, Dharamsala, Hyderabad, Ramachandrapuram – and the list continues to grow.
To help build the community, and to bring the opportunity presented by the Hackaday Prize to local hackers, I hosted Hackaday Prize Worldwide events at the Maker’s Asylum in Mumbai and at Workbench Projects in Bangalore. This month, on July 18th, I’ll do another Hackaday Prize Worldwide event at the Maker’s Asylum in New Delhi. I love talking about, and supporting, Open Source Hardware at every opportunity. So for this event, I’ll be doing a fairly long and detailed workshop on KiCad – the awesome, open source EDA tool – lasting several hours. At the end of the day long workshop, I hope to get fellow hackers to complete a design that can be sent off for PCB fabrication. After a short break in the evening, we will have a Show-n-Tell, getting the assembled folks to show off the projects they are working on. There are a number of them who have submitted entires for the Hackaday Prize, so it will be interesting to hear them talk about their experience and share tips and ideas.
We can hold only a limited number of folks at the event, and slots are quickly filling up. So, if you’re in New Delhi or somewhere close by, do RSVP at this link quickly. Looking forward to an interesting event. Check out some pictures from the opening party of the New Delhi Maker’s Asylum after the break.
Bengaluru (formerly Bangalore) is a town full of awesome hackers. So when Workbench Projects, a local maker space there, asked if I’d like to come down and talk about the Hackaday Prize, I immediately set things in motion. We decided to arrange a “Bring-a-Hack” event, asking local makers to turn up with their hacks and give a talk or drop by and discuss ideas that matter. To reach out to a larger audience, we also partnered with IoT-BLR, a pretty large group of IoT enthusiasts in Bengaluru. 10,000 Startups (NASSCOM for Startups) helped ensure that all the hackers were well fed with sandwiches and cookies while Paper Boat chipped in with a cooler full of beverages. A freak hail storm meant that we had to delay the start a bit. But that turned into a blessing of sorts, as it allowed those already at the space to check out the hacks that had been set up at demo tables and generally network with each other.
almost 100 Hackers turned up
[Anupama], who set up Workbench Projects with [Pavan], set the ball rolling by telling us about how it all started off a year ago. She and [Pavan] had ideas buzzing in their heads, but no means to prototype them. “You can either continue cribbing about the lack of maker spaces, or jump right in and start one on your own”.
We then had [Pavan] tell us about the various “studios” that they have set up. He was also excited to announce their addition to the world-wide MIT FabLab network. Their space is located right under the escalator that goes to the Halasuru Metro Station. The use of that space, which would other wise have been wasted and empty, itself is brilliant.
I stepped up and talked about the Hackaday Prize and our call to makers this year to “Build something that matters”. I showed off last years winners, this years prizes and gave out other details asking the assembled hackers to jump in and submit their hacks to the Hackaday Prize. Next up we had [Nihal], who founded IoT-BLR and talked to us about their projects, events and initiatives. IoT-BLR is the 3rd largest IoT-focused Meetup community in the world.

With that done, we opened up the floor for the assembled hackers to come forth and talk about their hacks. First up was [Anmol Agrawal] who showed off his earthquake early warning system which was prototyped using Littlebits, PubNub and Ruby.
I was glad that at short notice, my friend [Mohammed Khasim], who works at Linnaro, agreed to drop by to talk about and show off the modular phone being developed by Google as part of Project Ara.

The all-girls team of [Kruti], [Chitra] and [Archana] showed off their intelligent cane for the blind. Five ultrasonic ping sensors, one light sensor and a camera are all hooked up to a Raspberry Pi running off a battery pack. The cane communicates with a paired smart phone and the app provides audio cues. There’s also a pager motor for haptic feedback.
[Rahul] and his team showed up with what looked like the Iron-Man Arc Reactor on a T-shirt. It turned out to be an HID device that could be used to send key presses back to a paired computer. Their next iteration was less flashy and unobtrusive. They are now working on using this to provide safety for school kids by allowing them to send alerts in case of an emergency.
[Chetan] and his team from EdgeVerve showed off the work they are doing with putting various sensors on drones – CO2, temperature, humidity, multi-spectral camera – to enable them to be used for some real world applications. They have also integrated collision avoidance using cheap ultrasonic sensors and a ballistic parachute which deploys during an emergency.
The IoT-BLR connected cars project team talked about their project to tap into on-board diagnostics on vehicles and use the various sensor data to control pollution.
[Kumar Abhishek] came down just in time to show us his BeagleLogic. I had written about this project on the blog earlier, and it was nice to be able to see it in action.
There were some more projects up for display. [Osho Bajpai] had a demo of his “Smart Driving alert system” which detects if driver is falling sleep and wakes him up. [Sanju Mathew] demo’ed his prosthetic arm while [Supreet Joshi] showed off his “Smart Robotic Arm” which replicates the movements of a human arm using a smart glove. On display was also a remote controlled skate board driven by a BLDC motor controlled via the ESC. It was also interesting to see a bunch of school kids wheel in their chopper-inspired bicycle which is still work in progress. Those kids are learning a lot in the process such as ergonomics and welding. [Abdul] showed off a couple of devices he is working on to help harness tidal energy from coastal areas. The team from WiSense showed off some network connected environmental sensors. One measures soil moisture and temperature and transmits data via text message over GSM. This is aimed for use by Farmers and alerts them to water their farms at the right time. Another sensor worked as a tank level detector and controlled flow rate to prevent over flow.

By this time, it was quite late in the evening, so folks spent the next hour looking up the various projects, talking and getting selfies taken using the OpenSelfie photobooth that I had set up. [Rishi Bhatnagar] from Workbench Projects, who set the whole event in motion, managed to archive the evening’s proceedings and you can watch the (long) video after the break.

Bangalore, India evokes different responses depending on whom you ask. Old timer’s remember it as the Pension/Retirement City (not any more though). For other’s, it’s the Silicon Valley of India. And some call it the start up capital of India. For me, though, it brings back fond old memories. This was the city where I got my first job after finishing College in Mumbai, at the princely sum of $20 a month way back in 1986.
A lot of water has flowed under the bridge since then, and next month will find me back there at another awesome Maker Space called Workbench Projects, talking about the Hackaday Prize and how we can get hackers here to solve some of our big issues. We have huge problems in all sorts of areas – Pollution, Water resources, Energy, Climate, Agriculture, Transportation, Education – the list is long.
On Saturday, May 2nd, at Workbench Projects hackerspace we will gather for “Bring-A-Hack @ Workbench Projects” to talk about our passion for making and hacking. We’ll discuss the 2015 Hackaday Prize which offers $500,000 in prizes for hackers who can build solutions to problems faced by a wide-range of people. What does that really mean? That’s one of the topics of the evening. Of course there will be plenty of time to show off your own hacks, ask for advice on difficult projects, and to socialize with everyone that attends. Please visit the event page for all the details.
[Bill Meara] has finished up his radio. It both looks and sounds great. It was only a few weeks ago that [Bill] posted a guest rant here on Hackaday. The Radio he mentioned building in the rant is now complete. The transceiver itself is a BITX, a 14MHz Single Sideband (SSB) radio designed by Ashhar Farhan VU2ESE. Ashhar designed the BITX as a cheap to build, and easy to tune up transceiver for radio amateurs in India.
By utilizing parts easily sourced from scrapped TV sets, the BITX can be built for less than 300 Indian Rupee – or about $4.70 USD. In [Bill]’s own words, “Five bucks and some sweat equity gets you a device capable of worldwide communication.” He’s not kidding either. [Bill’s] first QSO was with a ham in the Azores Islands of Portugal.
[Bill] built his radio using the “Manhattan” building style, which we’ve seen before. Manhattan style uses rectangular pads glued down onto a copper ground plane. It makes for a more flexible design than regular old dead bug style building. Looking at all those components may be a bit daunting at first, but plenty of support is available. [Bill] has an 18 part build log on the soldersmoke website. There also is an active yahoo group dedicated to the BITX.
[Mahavir] sent in his group’s final project for the College of Engineering in Pune (it’s over here). They built an accelerometer based Bluetooth mouse. They ended up creating a mouse that maps rotational movements to x/y motion. From the video movement, it strikes us as responding the same way that touch pointer mice do. You can hit the demo video after the break or get more details from the project page. Even if you’re not into the mouse idea, you can probably learn something from their Bluetooth implementation.
