I have 3 ideas on how a 3D printer can:
1) be used to make very space-efficient electronics.
2) make some very precise and smooth parts.
3) be built very cheaply, very compactly, yet very precisely with a minimum of moving parts.

Thank you.
I got another question related to my design:
If there is a material that has a surface resistivity and a volume resistivity,

How do I find a resistance across a rectangle that is 10mmX10mmX{material sheet thickness mm}. I need to find...
How do I choose a conductive (IC packaging) foam for a DIY pressure sensor?
I need to find the foam material with the least permanent distortion strain so my sensor would be able to function at high speeds without problems.
Unfortunately if I buy the foam through the Internet I cannot tell how...
What circuit would I need to use a pressure sensor as a switch?
Do I need a comparator or a Schmidt trigger for this?
I have a lot of bipolar transistors. Can I use simple transistor switches for this purpose?
I would like to make a circuit with an adjustment knob to adjust how much pressure...
Hello.
My design calls for 38 rod clamps that can hold 1/4" steel rods at 90 degrees firmly if the set screw is tight, yet not be wider than 1/2" themselves. I am looking for a cheap catalog where I can order those parts without burning a hole in my wallet.
They sell them at chemical laboratory...
So what kind of cheap and finished-looking device can I use as an easy to interpret finger pressure sensor?
I dont want it to be a microswitch since it has to work through out the area of the whole finger.
If I clean surgical tubing and surgical gloves from talcum powder, would silicone stick to them? I will place a glove over the cast of my hand mo smooth out the surface on the inside.

I feel like microphones serve as good pressure sensors, I would like to know what kind.
I am not an expert either. I am not an anatomist. The reason I am doing this is because I think that keyboards were not updated since 19th century. I want to start writing.
Life is difficult. Nobody would give a hand in this project locally.
What would prevent me from making a mold off my...
Hello
I have been working on an alternative computer input device for a while.
I wanted to resurrect the forgotten concept of the Corded Keyboard.
I have several possible ways I can make it so combinations of five fingers (pressing up or down) can output 26 letters of English alphabet and other...
Hello
I am looking for a job that is related to illustration of technical concepts.
I know Solidworks 2012, Adobe Photoshop, Adobe Illustrator and some other technical design software.
I could not finish my degree because of financial complications and I am currently looking for a job in the...
I am not skilled enough to describe what I observe in any manner.

I have yet another question.
I was wondering what determines the rate at which my capacitor charges through an Avramenko Fork and realized that ceramic capacitors charge significantly faster than their...
Maybe there is a capacitive return path. I am not arguing for or against anything, but I see no obvious place where a capacitive return can occur in an Avramenko Fork circuit.
Maybe a single line that this circuit is powered with acts more like a wave guide than a traditional power line. I had...
I cannot find a good website in English that would explain the alternative theory, but experimental lines of several hundred meters were constructed, delivering kilowatts of power to the load. I am not sure how it works but it is definitely no capacitance because the rate at which this circuit...
