Ask MAKE: Liquid level sensor for brewing system?
What is the best method or type of sensor to use to accurately detect liquid levels in the kegs?
Ask MAKE: Three leaded piezo?
I have been experimenting with my Arduino and piezo buzzers as simple speakers – noisy and fun. But one question has been bugging me, what on earth is the third blue lead for on some piezos?
Ask MAKE: Software for designing circuits
I’m doing my 2nd Arduino project (and 2nd electronics project ever) and am trying to design some of the circuit stuff on computer instead of just wiring it up or scribbling some stuff on paper. I’m trying out Fritzing and am wondering if you have any other suggestions for software that can be used for breadboard, schematic and/or PCB design.
Ask MAKE: Repurposing electronic detritus
I have all this electronic detritus that I would like to re-purpose (i.e. a couple old Compaq iPaqs, a bunch of cell phones, several laptops, several old desktop computers and monitors).
Ask MAKE: Image sensors: CCD vs CMOS
I was looking at buying a digital camera, and read that there are two kinds of sensors that they can use to take a picture- CMOS and CCD. Can you tell me what the difference is, and if one is better to get?
Ask MAKE: Playing back a recorded sound
I’ve been wanting to make a prank project, that I can leave somewhere to play back a recorded sound and flash some lights. I’ll use LEDs for the lights, but don’t know how to play back sound.
