Connecting 10AWG wires to PCB

I have 4 wires 10AWG stranded, that I need to connect to a PCB that I'm designing. They will be in a high vibration environment, so direct through hole soldering may not be the best solution. I've thought about ferrules, but those are usually used…

What PCB wire termination should I use for high-vibration environments?

I'm designing a system for a high-vibration application. I need to land wires on circuit boards. Someone suggested that I use a Wago cage clamp, and that there might be similar things from other manufacturers. The cage clamp was described as useful…

How do I build a bracelet that vibrates once every n minutes?

I intend to establish a few new personal habits that eventually become second-nature to me. To assist myself, I want to wear a bracelet that vibrates every, say, 5 minutes all throughout the day as a constant reminder to keep up whatever new habits…

Is a screw or push-in terminal better for vibrating environment?

I need to decide what connector to use on my PCB to connect low power wires. Among the available options on Farnell/Mouser etc. The price and size are almost similar. I wonder if using a screw terminal or a push-in terminal would be better for a…

Minimum wire gauge with vibration

I've heard that there is effectively a minimum wire size for vibrating environments. In other words, when designing wires that will experience vibration (in my case, an automobile), it's recommended to make all wires 24 AWG or larger, regardless of…

Electrolytic capacitor failure mode

In a project we're working on, we had an electrolytic capacitor explode on us. It was a surface mount device, UCM1H470MCL1GS from Nichicon: So far, we've seen our project run for many hundreds of hours without incident, so I'm fairly sure there is…

Using Piezo Vibration Sensor with Pull-Down Resistor - Arduino

I'm using a MEAS piezo sensor (this one: https://www.sparkfun.com/products/9196) to detect very slight vibrations, but I'm having trouble selecting a pull down resistor that allows it to be sensitive, but not so sensitive that it just keeps…

What is the most power-efficient way to generate vibration in a small area?

I'm trying to generate a perceptible vibration (as felt against skin) in a roughly 4x4mm area. What's the most power-efficient way to do that?

How to detect very hard impacts with piezo?

Normally I'm a software guy, but I've recently decided to try my hand at some electronics projects. What I want to do is make my own impact sensor for target shooting. What I'm picturing is a piece of AR-500 steel for the target, and a sensor that…

How would you dampen this little quadcopter?

Well, I made a little quad from scratch. From scratch as in from PCB design. After assembling, testing, some coding, it turns out my accelerometers get WAY TOO MUCH vibrations and I can't detect orientation using Kalman filter... Bump! Has anyone…

What is good device for generating vibrations, offset weight motor or solenoid or some other?

I am building a vibrating device for that I am thinking to use a solenoid for vibration. The solenoid will be used such that device will be mounted in the floor and when a stick is put over solenoid, it will start vibration. That vibration needs to…

Vibration Detection bronze keyed instrument

I want to be able to detect when a bronze key (Balinese Gamelan) gets struck by a mallet (hard wood) without effecting the keys vibration, so a piezo is likely out. Example of the instrument: Is there a cheap optical vibration sensor that could go…

Why do vibration sensors use a negative voltage?

I've started looking at some industrial vibration monitoring sensors for a project and it seems like there's a number of brands that use negative outputs voltages. Many are eddy current sensors with specified supply voltages of -24 VDC and output…

Why would an AC motor heavily shake when driven with certain frequencies?

I have an AC motor from an old TCL 160 Boxford NC Lathe, it has three wires named U V and W. I thought that incorparating the original driver to a modern control interface card would be difficult or unreliable, so I got the motor out and wired it to…
