I have spend some time designing a new vane for arrow. A wind tunnel is what we have tested the concept and with pretty good result. It really concern me quite a bit since I do not have formal aerodynamic airfoil training. I just do not want to told that I am in nuts to design some thing that...
I end up doing both. Can you believe the difference in price of what is made in US and in China? The strange thing is that they both use chinese parts.
Thanks Strong for locating all those Accelerometers. The only issue is that everyone of them use power. I need a real switch that do not draw ANY power. So accelerometers are all but out. In order to get 5 years shelf life base on a 25mA battery, any power usage is unacceptable.
Piezo film is a very interesting approach. the only down side I can see is that it do require IC to make it work. The space I have do not allow me to have all those and the wight is another significant issue. Not to mention the power source which is 25mA battery. I e-mailed them and see...
After I talked with a MEMS company, they want something like 100K design fee to start with, then prototype fee, etc. I think base on the amount and my budget, that is definitely out. I do think the current package in COMUS have potential. Do anyone know of another company that may have...
It is the same. just that I forget about my password and I send out 4 times with no respond. So, I just decided to use a new name. Sorry for the confusion.
I also find out that MEMS is not the greatest in being a non electronic control switch. That is why I am looking at other mini mechanical switch. may be I have to repackage the unit altogether. But this is worth a try, IMHO.
I only need it to work MOST of the time. like 80+% would be good enough and low cost. My entire application including battery is only 1.75" X .24" and it weight less than 1 gram, battery included.
VE1BLL, no, nothing to do with that.
Madcow. That is similar, but I need it to be 25% size of it. It is way too big for what I need. It cannot exceed 1.4 mm in height.
I agree, Sorry for the typing. I just not sure what to type on the screen for that square is hard to do. so 5G switch is what I am looking for. It need to be really small. MEMS is what I have in mind, but that is not that simple. So it is not simple or anyone and everyone would have done...
