I like this one a lot more than the other one... bearings and whatnot makes it all so complicated. And for one thing, if it ever got to the marketing stage it would be expensive. Since that "Handsteady" you pointed to sells for £39.99, and assuming that is a fair price, imagine where yours would need to be priced at. High price means small market means little interest.

This one has simplicity a style, imo. Find a suitable fluid. Get a prototype in working condition. Then try it on grandpa and others. And don't be disappointed if, after you've given it your best effort, it just doesn't work out. Whatever was learned will come in handy somewhere down the line.

A piece of advice: You are fairly safe seeking encouragement here among fellow makers, but be warned that the general public takes great pleasure in shooting down any and all new ideas. It is best to refrain from pushing your baby into the mean streets before it is somewhat fleshed out, tested, and can fend for itself.


I like the simplicity here, and what a nice story you have about helping your grandpa, but yes, beware, the general public and even your non-maker friends will attempt to shoot down your ideas..... watch Shark Tank.

Just remember how many times Thomas Edison failed before his success! Don't give up with your maker spirit! If not this thing, something else might come along in your head. I like this idea though, my father is starting to develop a tremor. Good luck.

Hey Thanks for the feedback!
I like this one a lot more as well, when I evaluated the designs this one actually worked the best for specific wrist tremors (aside from the leaking, the tiny handly, and the fact that the mug is massive). However, I disagree about the market stage, If these designs were finished and worked as intended then they could be perhaps created from injection molds and be produced relatively cheaply. And I'm pretty sure the demand for a product like this (if it worked) is relatively consistent regardless of the price tag.

Thank you for your advice. tbh I have put these projects up because the science fair is now over and I want to get on to bigger and better things. If there is interest in developing them further then I will do that, and I welcome all feedback. If someone wants to take the project even further then I'd be happy to provide them with the research and progress I made during my month of development.

well....Injection molding is cheap but only in large quantities. Run the idea past a molder. They are happy to talk about it. My guess is the molds will be in the $30,000 - $40,000 range each and in the present form this things needs at least two. Or, the molder can own the molds which defers that cost, but you nevertheless are committed to buy some large quantity of molded parts, likewise several 10's of thousands, and you might pay a buck or two per piece (not counting material). I don't know if this could be profitable in the obvious, primary market alone.. maybe if it extended into children's drinking cups... and travel cups... airlines.. who knows... gotta research it.

Ferrofluid came to mind when I saw the cup... a magnetic liquid damper. Add an electromagnet, a cell phone type accelerometer and a processor. Customized feedback according to the individual patient. The technology is pretty much worked out but ferrofluid remains one of those offbeat ideas in search of new applications.
So many things out there but so little time to play with them... Later. Have fun.
