Implemented an autofocussing algorithm on our lithography system @hackerfabindia - an important step towards automation, the algorithm controls servo motors connected to an XYZ stage
Left to right- Demo, Focus picked by algorithm, Best focus
Still some room for improvement!

@pramode_ce @PcbCupid make open hardware boards (GLYPH series) and add on modules. They are steadily building a nice ecosystem.

I am trying to create a list of companies bringing out affordable "made in India" development boards/kits for hobbyists.
These are the products/companies that I am already aware of, please comment if you know others. The hobbyist ecosystem is very important and we need a lot of companies to tap into it fully!

Ever wondered how we turn silicon wafer into chips?
We did @hackerfabindia and are making a student built chip fab.
Come visit us for a lab open day as we demonstrate our systems at IITB on Wednesday 15th April, 2-5pm to learn more.

We are launching Maximus Ventures to incubate startups focusing on electronics supply chain, capital equipments, design tools, and anything related to manufacturing technology in 🇮🇳
We are not Zoho or Zerodha big yet, but we want to do our bit to build the ecosystem.
We have already incubated 2 companies-
1. Building AI based electronics design tool ecosystem.
2. Nanomaterials company building disruptive copper nanomaterials for PCB and electronics industry.
We need to build strong brands in materials, industrial supplies, and machines.
If you are building in this space, DM @Raosted

Tech seems to be getting effectively nationalized. Starting from around 2020, we've seen an increase in export controls on things like chips, critical minerals, restrictions on advanced manufacturing equipment and various other trade restrictions. Supply chains have become a security issue for countries. We're no longer in a world where India can be okay with just exporting IT services. If we don't build domestic deep tech capabilities, we'll be locked out when it matters most. Self-sufficiency has become necessary insurance. India's startup ecosystem has come a long way. We have genuine local talent that can build a lot of what we currently import. They just need the right support. The recent government push for deep tech is a step in the right direction. The timing also matters. If AI can pretty much produce all of the software, asset-light models will get hit. The next decade belongs to atoms, not just bits. You're already seeing this with money flowing into data centers, defense systems, batteries, semiconductors, advanced manufacturing. You can also see this in VC investment flows. In the last decade most of VC investments went into eCommerce, lending, and payments. Those segments have now matured and the easy opportunities are gone. For deep tech, it's still day one. We have the talent but what we don't have is the ecosystem around them. Comparisons with China are cliched, but they didn't become an industrial superpower by accident. There are lessons we can learn. China's internal market is brutally competitive. Hundreds of startups compete in a given sector and this forces them to innovate and be efficient. Indian states used to do this for software parks. Why not for deep tech? Tamil Nadu, Gujarat, and Maharashtra are success stories but we need more states in the race. Companies choose to manufacture in China because everything they need to manufacture is within a few miles. This industrial clustering creates genuine competitive advantages. You can create a design in the morning and have a prototype by evening. This density took decades to build, but we can do it if we invest with a long-term mindset. China also built real bridges between universities and companies. In India most ideas die in the minds of students. Brilliant PhDs can't find the capital or institutional support to build a prototype, let alone turn them into businesses. We need government procurement guarantees. Patient capital that understands hardware burns cash for years before revenue. Pathways from idea to commercialization. The government backing deep tech is a good move. But support can't just mean funding. We need R&D tax credits, subsidies, first-purchase guarantees, streamlined approvals and other incentives. All of this has to be sustained across decades, not election cycles. Without domestic deep tech capability, we stay dependent on others for critical infrastructure. That dependence is vulnerability. If we build the clusters, invest in education, fund the R&D, bridge academia to industry, and let states compete to create ecosystems, we get more than self-sufficiency. We become a deep tech exporter. The bulk of our recent investments through @rainmatterin have been to support homegrown deep tech startups.

We have been working on an (affordable) FPGA board to lower the barrier to teaching/learning the fundamentals of Digital Hardware Design.
The target audience is Students and Engineers interested in learning how digital hardware is written (using HDLs), how to create state-machines and how a CPU may be designed.
If you are into software - understanding how digital hardware is designed will unlock doors to writing performant and accurate system/embedded code.
If you are interested in the board, follow the updates here - pyjamabrah.com/soanpapdi

@nileshtrivedi @ganitlabs Most of these HEIs are merely passing people... It's a myth that students can be industry ready. The mind needs time to learn fundamentals. They can be trade ready, that's the job of polytechnics. time to rename colleges to polytechnics, unless they can prove otherwise!
English
I couldn't stop thinking about this article from @ganitlabs.
That headline: "Courses that don't matter, Graduates whom no one wants" should light a fire under all those who decide education policies.
However, I don't like the recommended "Balanced approach". It comes from the zero-sum mindset of "More practical skills must mean Less theoretical knowledge".
There are innovation available from cognitive science and learn-tech, that greatly enhance learning rates for everyone. I can speak for hours on how much low-hanging fruit is out there to grab.
I believe every human is capable of becoming a productive worker AND a knowledge-creator.
I am not saying every student is equally bright. But are the separate classes of "Doers" and "Thinkers" a fact of nature? 🤔
Once again, I am reminded of MIT's motto: "Mens et Manus" - Latin for "Mind and Hand".
Am I wrong or too idealistic? Or is it really a case of low expectations seeping into our mindset?

@nileshtrivedi @AThya109 Our computers are now N times more powerful than in the past. This arch uses that for applications like education. Getting a new hardware architecture adopted is a steep uphill battle though.
English
@shreekumar3d @AThya109 Looks like multi-seat linux. Ubuntu promised that but I don't think it ever became usable.
English
Since general purpose computing started becoming slop, kids now need a dedicated operating system. Schools are not at all prepared to configure software in a good way. And so, their response became "screen-time is harmful".
Years ago, I had hoped that Google will build the right thing. I even hoped that well-funded Edtech startups like Byjus - which had started selling tablets with preloaded content - will ultimately realize this and solve it.
Turned out to be a huge disappointment. Can't even trust "YouTube Kids".

“Although it once seemed like a good idea to give every child his or her own device, it’s clear that those policies have been a failure.” 💯 School-issued laptops distract students at school and home, expose them to things they shouldn’t see, and hurt learning. 🧵
English
@nileshtrivedi @AThya109 Right. On the OS side it's similar to multi-seat linux, and beyond that there's a hardware implementation that works on video - moving session video and managing input over HDMI
English
@nileshtrivedi @AThya109 Been ages since I heard LTSP. Everything is client/server now :) That hardware has no client !
English
@AThya109 @shreekumar3d This just reminded me of LTSP from 20 years ago. Is that still a thing?

@sohamsarkartech @nileshtrivedi FOSS is subject to sovereign laws. RISC-V moved HQ to Switzerland to address these concerns ahead of time. The linux kernel ? They simply removed Russian devs! The core principles are sound, but we don't live in an ideal world.
English
@nileshtrivedi I couldn’t help noticing that this is a copy of openalternative.co, yet there’s no attribution and how does a geographic movement align with the ethos of OSS? The core principle is to be freely used, modified, and distributed by anyone, regardless of borders or nationality.

Despite my concerns with bad software being sold or imposed via govt in the name of patriotism, I think sovereignty of tech infrastructure is too important to ignore for India.
So, I am putting together this catalog of Indian-made alternatives to popular global software products.
What are some high-quality made-in-india software products that compete well globally? Would love to add them here.
Nilesh Trivedi@nileshtrivedi
I am not an isolationist but I do think capability building is important. "Focus only on your strengths" is not a good advice, from risk management perspective - for individuals, companies & nations alike. What happens when your "strengths" are no longer valued by the market?

Humbled to share the simultaneous firing of two of our electric pump-fed semi cryo engines, controlled by our in-house engine computer software. Since these pumps are driven by electric motors there is increased level of control available to balance the thrusts across the engines compared to conventional thrust balancing techniques
