Using it to (hopefully) drive a 6-wire linear actuator, which will slowly push a syringe pump. The motor is a Hurst SLS custom-jobbie I got from a surplus dealer here in Silicon Valley; the label says 12VDC, 11 1/2W (which, in my newbie brain, means about. 96A; 12. 5 Ohms. ) So - what are my power supply requirements/hookup (Sorry, but I wasted my education on an MBA,

and am mostly trying to learn chemistry lately - my EE knowledge is decades old. ) TIA! I would aappreciate a little help. I intend to use a 2. 7A motor, but is aware that tnhe the sense resistor cannot be lower than 0. 66 ohm. I understand that R14-R17 has to be changed, and so do R18-29. Have tried various values, but it`s it been really a shot in the dark. Could you be able to suggest some values are starting point. James Newton replies: You can use the form about half way down the page at to find the sense resistor values to use for your target motor current. I`m a little confused as to why you feel the other resistors must be changed. + I am using a US Cyberlab Neuractor CNC-4+ kit that I built 10 years ago. My software is DANCAM. My motors/drivers are pretty whimpy. Do you know if your stepper driver has been used to retrofit a CNC4+ kit to provide better torque and speed Thanks, Durl They say that there is no such thing as a stupid question, I say "Are they nuts" Please clarify, can one linistep control multiple motors from one printer port Futhermore, I just "ebayed" three (Hy200 Nema 34 170A8 1. 7 amps) motors. I paid nearly $50. 00 USA, is that a good price, and is that motor suitable for the linistep Thank you very much for your help. James Newton replies: One lini per motor. I don`t know, I pull my steppers from old copiers, printers, and fax machines. If it has 5 or more wires, it will probably work fine. + Hi...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
