Buying Optical Electronics

Buying Optical Electronics

On mobile, sorry if the formatting sucks.

Im looking for deep IR (1-5.5um) photodiodes and im having a terrible time dealing with these companies. Theres no prices on their websites or ordering options. I have to go through sales people (kill me) and when they find out that I want low quantities of these they seem to lose my email.

Digikey only has photodiodes up to 1.7um, so thats not much help. Anyone know of a company that isnt awful to deal with or will sell in low quantities?

How does the landscape look for Aerospace engineers?

I'm about to go into my fourth semester in mechanical engineering but tbh I'm only in mechanical because I think they have more job security (as in they will always be needed), since i was a kid I've been fascinated by the aerospace industry and i think i would like it much more.

The problem is I've heard from various teachers that recently graduated Aerospace students are having trouble finding jobs in the industry because of how flooded the specialty is getting.

I'm trying to get a feel for the industry, is it possible to work there as a mechanical engineer? how likely is it and how good is the money? is it true the market is flooded with recently graduated aerospace engineers?

Thanks in advance.

I want to lift and lower a weighted ball using a crankshaft, but the stroke is too short. Any way to multiply the stroke length using a crankshaft or similarly simple mechanism?

Need Help with a mechanism

Hi All:

I am playing with a hand crank mechanism that transfers motion in the perpendicular direction as shown in this pic.

The shaft with two gears (encircled in the picture above) is the shaft that changes the gears. I want to create a mechanism that would help with changing the gears by the operator.

Any help is highly appreciated.

Thanks!

Looking for information regarding wifi connectivity and test engineering

What are the basics in knowing about connectivity between a device and a Wi-Fi router and a device and an LTE connection. What are test strategies of digital devices and IOS/Android applications for recent digital devices such as E-readers, dash, Echos, TV, etc. and as well, the new Alexa Calling and Amazon Video apps. Also play out scenarios in your head in which these devices/apps do not work and what you would do as a Test Engineer to characterize those observations.
