20 Steppers

Hello,

I'm writing software which will have 20 or so variables that will update stepper motor positions simultaneously (or there abouts). I don't want to create my own electronics as it's not my area of expertise, what would be the best off the shelf solution for my application?

where to find a pulse relay

I have a thermostat project which run from 2AA batteries The microprocessor has a minimum consumption current In fact the whole project run in just 1-2 miliamps. The big issue is the output of thermostat. Most thermostats, to conserve power , and change the battery maybe once a year , use latching r...

Soft start dc motor controller

Hi All, I am looking to build a dc motor controller for a model ski lift. at present it only has an "On Off" switch, I would like it to include a soft start, reverse and half speed switches (push button type). The motor drags about .6 amp and is a 6 volt dc type. The idea is to give the model full a...

Rotation detection sensor with schematics

Hi All,
I need to know the mechanical sensor or other sensor which can detect the rotation of chain.
When the rotation of chain stopped it should trigger alarm using 24v buzzer.
Kindly help me to over come this circuit.

ET-ROBOT 877 program follow line

Hello

I received an ET-ROBOT 877 kit, which seems very interesting. I would appreciate you could indicate me where can find a program to control the robot following a line on the floor. I saw a youtube video about it, but can´t find a similar program. Can I buy it ?.

Thanks for your attention.

cancer defeating nanobot for real

there in the news some australian scientists have made magnetically controlled calcium fluoride nanoparticles that give off nascent oxygen near cancer forming cells when exposed to x-rays killing cancerous cells in the reaction a breakthrough after IBM made pathogen sticking nanoparticles but failed.

Detecting an external resistance on a motor

We are building a very cool project for school (x-wing fighter) with functional cockpit canopy that opens and closes by linear actuator (Arduino, relay, limit switches, etc.). We cannot figure out an efficient way to detect resistance/obstruction while the canopy is closing but before it reaches the...
