 So, finally we made multiple units, we made multiple sets of PCBs with different intensities. Acrylic has its property of piping light, so we used acrylic buttons between the LED and the human skin so that heat doesn't pass on to your skin. Now look at the convenience, look at the form, look at the holding, how easy it is to hold, how convenient it is to do. So tell me now all of you, what should I do from here? I should do the whole journey, what should I do from here so that I take that plane and go off to mass production, file process is done, we wait 10 and we test it out, what should we do? Approach small industry, good, what else can we do? Collaborate with established companies in the field, very good, collaborate with established industry in the field, very good, what else? How can I take this product to the market, quick? Let the people know about it. We did that, we put on papers and I got thousands of calls. Collaborate with the startup. Collaborate with the startup, its statement is wrong, how can you collaborate with the startup, that guy is so struggling in his own startup, what will he do for us? So what should be your statement be? Startup. Make a startup, encourage your students to start up, put 4 people together, there is a lot of value in this product, let us start a company and let us make this happen. So you have answers, but why is it not happening? Finance, human resource which we don't even consider are the most critical aspects. So to come out of this, you have the solutions in front of you. I also know all these solutions, but it didn't happen. So we are still on this, so we will see how before your course gets over, if we can do any of these three, we will find out. So what are the learnings from our first C? We said we are going to do a thorough user feedback. You have seen that there is a user feedback and suggestions and improvements at every stage of your design development. Let it be a mock-up, let it be a rig, let it be a working prototype, let it be a pilot production. You have constant input so your product can come up in a very, very good way. So you bring in synergistic R&D and prototype manufacturing in the team. Right, we did that. We got the best PCB manufacturers from Bangalore to work with us. And now the same team is actually ready to do the tooling and manufacturing and identify a manufacturer who will manufacture and supply to us. And we will find a distributor to distribute all over the country or all the world. We started with Blood Bank, then we improved the context to blood testing. So we keep moving and then we finalized after our user study, we noticed that we just can't service everybody. We were actually good with 60% of the total user segment in this area. So similarly, we are attempting to 60 to 70% of the market. It's a big thing. It's a great start-up idea.
