Technology Changemaker
TEDxYouth@Hyderabad
The case for pointing one manufacturing technology at problems it was never sold for. Also on TED's own site.
I bring the hardware.
Most manufacturing talks are slides about manufacturing. Mine end with something the room can pick up.
Talks and workshops.
The factory that fits in a backpack
Where distributed manufacturing genuinely beats scale, where it does not, and how to tell the difference before you spend the money. Ends with a printed turbine rotor going round the room.
Keynote, 30 to 45 minOpen hardware, and what it actually costs
Ten years of Hackaday Prize entries and one Grand Prize. The leverage is real and so is the bill, and almost nobody talks about the second part.
Keynote or firesideMaking physical products in India
Thirteen years of supply chain, hiring, pricing and customs, told without the patriotism and without the despair.
Keynote or panelDesigning for cost from the first sketch
How the Braille module got from a piezo stack to a printed cam and a micromagnet, and what that process says about designing for cost from the first sketch.
Technical talkDesigning for a machine that prints
Hands on, for engineering teams. Bring the parts you are stuck on. We redesign them in the room.
Workshop, half daySee me in front of a room.
You do not have to take my word for how this goes. Nothing loads from YouTube until you press play.
Inventor in Focus

TEDxYouth@Hyderabad
Technology Changemaker
There is a recording, so you do not have to take my word for how I am in front of a room.
The talk is on TED's own site rather than only on YouTube: watch Technology Changemaker. It is about applying one manufacturing technology to problems it was not sold for, from accessibility devices to a turbine that ran in Antarctica.
In 2025 I spoke at Embedded India on open-source hardware for accessibility and the Hackaday Prize journey behind the Braille display, and I have appeared on The Inventor Challenge twice. I have also spoken at universities and maker events across the country.
I am comfortable with a technical room and with a room that has never held a printed part.
What a programme gets
A speaker who has shipped the thing he is describing, and who will say where it went wrong.
Talks run 30 to 45 minutes, or half a day for a workshop. I travel from Bengaluru. I can bring machines and printed parts, which is usually worth the freight.
For fees, dates and a speaker pack, write to me and say what the event is and who is in the room.
