Here you will see some of my many project ideas, stuff I wanted to do etc.
You could get inspired from this, may be contact me at sibusaman at gmail dot com to share your views and ideas and suggestions.
Just link back to this page/mention me if you are adopting any idea from this, also document your work and share with all and send me a link, so that I don't have to start from scratch.
I don't need to tell you how frustrating and dangerous it is to drive when an oncoming vehicle do not use low-beam. Especially in India where people know how to 'ride' and do not know how to 'drive', this is a big problem.
So, the idea is to make a big LCD that covers your field of view, it could be the windshield of the vehicle or the glass in your helmet or a goggle you wear. There would be a camera to track your head/eye and another one to track light from oncoming traffic. Knowing the position of your eye and the light source the system will generate a dark spot in the LCD, just enough to cover for the bright spot.
The system has to have some intelligence to distinguish between headlight and other lights that should not be blocked like traffic signals/indicators etc. It would be nice if the system can anticipate the head movements.
The main challenge would be to make an LCD which can do this. Another challenge is the coding itself.
The codes for tracking eye/objects are already there.
A prototype could be achieved with two web cameras (for tracking the eye and the light source respectively) and a stripped down LCD display from a laptop. The LCD has to be stripped down so that all the reflector and diffuser layers will be removed, leaving with a transparent sheet of glass. Now we can create dark areas in the display so that it eclipses the light source behind the LCD.
A vacuum chamber to remove any trapped bubbles from mixed resin, silicone, castings, molten metal etc.
It requires a vacuum pump, do not know if venturi pump available in the lab is sufficient. For the vacuum chamber we need something transparent, something made of thick glass
or acrylic. Something like the following.

I had this idea while I wanted to get fruits from tall tree. Traditionally we used long sticks with something like a hook/knife at the end. Sometimes a net too to collect some soft fruits like mangos, before it falls to the ground and gets damaged.
The idea is to have a robot similar to a big crab. These two arms and hands will have a very strong grip and will be controlled remotely by the operator, preferably using his own arm movements his own arms and fingers.
The actuation mechanism is to be decided. Options like geared motor, servo, stepper, hydraulic etc need to be explored.
The actuation and grips need be quite strong stiff. We need to decide the positions of the heavy objects like the battery bank.
We need to have camera/s at the end of arm/central body to see what's going on. These image can be streamed into a mobile phone and can be viewed via a virtual realty headset.
The hands need to have some method to cut the stem of the fruit.
The idea is to have some tubing with a collant like water flow around upper and lower arms. The temperature of this liquid will be controlled to have heating or cooling effect. Personally I wanted the cooling solution, and I wanted to use it while riding motorcycles. I was thinking about a system that uses water as the coolant and controls the pressure in a water reservoir to lower the boiling point of the liquid to the desired temperature. In essence, instead of we sweating, the machine will 'sweat'. The water thus cooled will then be circulated to reduce the body temperature.
The system could use the heat from engine or the electronic circuit/motor (for electric vehicles) if we wanted to use the system for heating rather than cooling.
Initially I was thinking about using the liquid flow to cool your back and chest, but after seeing the following video, I decided to move to upper and lower arms and thigh.
But using a vest with embedded liquid channels will be a compact solution. The system should use a quick release mechanism, and I guess the low pressure inside the system itself will give some level of seal between the wearable part and the machinery (which contains the liquid pump and the vacuum pump). The quick release is, a the same time, convenient and safe in case of accidents.
Asus ROG-GX700V0 is a monstrociy that has a quick release liquid cooling dock. Though for not for low pressure, it's interesting and inspiring. But I want my laptop to have phase change cooling, just saying!!
These parts seems useful.
This is something like a sandblaster, but uses volatile solvents for cleaning. The point is to recover all the solvents used, purify/distill them to pure form; recycle. This way we can prevent harmful/toxic solvents escaping to environment. The energy cost may be high, maybe not, it might be cheaper to buy new solvents than to recycle them, but when environmental impact and health issues are considered, it could be for a greater good.
The system is a self contained unit having
The overall system will look like a sandblaster/laboratory fume hood.
