it is a brushless hobby motor designed for airplanes but has ALOT of torque and can handle unto 70A at my 25V nominal system. It is a 14 pole outrunner motor. We use 120 degree hall sensors to monitor position, rpm, I have just focused on current control and limits for acceleration. I use a PIC32MX250 micro controller Expert should apply which quick turn around. ready to hire now

Hi, I need a circuit board designed and code written for a device that will transmit a weight over GSM to remote servers. The signal coming in will be that of a load cell. I would like the inputs from the load cells to be intrinsically isolated if possible as well. Once the signal is received by the Micro controller, it needs to be sent by GSM. That signal will be sent to a remote server and a web application will use the data to provide customer specific information. The unit will be able to take from 1-10 inputs from the load cells for now, depending on the application. Some Digital outputs from the controller will also be transmitted for alarms. The unit will need to be battery powered, with battery level indication also transmitted. I was thinking that readings from the load cell could be stored up and every couple of minutes sent to server to save on battery life. The project is in South Africa. So, I will need controller, modem etc. to be freely available here. I would prefer...

I need to code an Arduino micro-controller to rotate different servomotors, depending on which pushbutton is pressed. Basically I will be making an automatic drinkmixer or bartender. There will be an rfid card and tag to activate the machine, and a series of pushbuttons to control which servo to rotate so that the fluids can be dispensed. This is a project for my programming class, but I dont know how to code Arduinos. I also would like a sketch of the circuit please Please open the attached file for more details Algorithm is attached.

[Description updated at 4:33pm PST, 3/16/15] Thanks everyone for your proposals. Last update before I pick a proposal: I should have stated earlier that output precision is important. I want to hear your plan for current sensing and how to get good mA output precision. I've read that combining high side with low side sensing is good. Below I've only updated "OUTPUT PRECISSION". Thanks very much! GENERAL DESCRIPTION: Needed is a prototype device (along with any parts lists, board diagrams, schematics, etc) which regulates output current from a battery supply, over a variable resistance between 30K ohm and 200K ohm, at or below 2mA. Output voltage will be controlled by the device to maintain the output current at 2mA. The device will feature a basic LCD character screen and button inputs. See attached mock for the basic layout and working of the controls. OUTPUT PRECISSION: Would like to get precision of 0.1mA or better, and know that 2mA will not be exceeded (safety measur...

Good afternoon, Upon being referred to this site by a good friend I am currently in need of help in implementing the embedded .c code that Texas Instruments provides for interfacing a TI micro-controller and the LMP91000. In my case I need it to run as a stand alone and should be able to provide .txt files for the recorded currents. Thanks. TI-provides a library but we are having some serious problems getting it to work.

Hello, My name is Robert, I am looking for individuals or companies to help design a custom highly affordable pid temperature controller that i can take the design to a supplier to manufacture for me. We are creating our own brand essential oil vaporizer but do not like the current chinese pid controller boxes on the market our goal is to have a custom one created so we can have our chinese factories manufacture. I am ignorant to this type of product but see all kinds of items on the market like Arduino or raspberry pi and i am very interested how cheap we can make this yet have the high quality parts and programming, We need this part to help build our own enail   [obscured]  /?gws_rd=ssl#q=enail Basically all this does is fit around the diameter of a circular titanium petri dish and heat it to a stabilized desirable temperature. (sort of like a retro fitted soldering station with a lcd screen to show temperature setting and actual temperature. With the finished product hoo...

UPDATED INFORMATION as of 2/22 7:30pm CST From bidders I want to clarify two details: 1. The current source code is ANSI C source that currently runs on embedded micro controller systems. This code will run on Windows. I believe it supports 32 or 64-bit environments but will check on that. 2. We are not very well versed in Windows or DLLs. We are embedded micro controller programmers. We do not know how the DLL should function. The first step in the project is to do an analysis of the software and design how a Windows programmer would want to access the functionality provided by our software through the DLL. We want the successful bidder to lead us through this design. There is a design phase for this effort. 3. I am not interested in speed of delivery. I want someone that can show me they have the skills to complete this project successfully. --------------------------------------------------------------------------------------------------------------------------- Overview We have...

I want to a SMD based PCB design with integration for GSM + GPS module. As we know GSM/GPS module's will be change time by time so I need adapter wise PCB design which means: main PCB will be any suitable micro controller but cheap as my product will be plan for sell able in Pakistan, and would have DB9 interfacing with various inputs and output pins for example pin for ignition and one for panic button etc. other PCB which contain GSM/GPS module with micro-SIM card holder with SD card module for GPS data preservation purpose. I've attached my old tracking device PCB which based on 89c51/52 but It does not have the MX232 installed I want it now for reviewing to attached with PC as well to program directly through pc using ISP.

I'm a hobbyist and maker looking for assistance with the development of an El Wire driver / inverter. My intention is to hand build a small number of these El Wire drivers, as needed, to use in my El Wire projects. The cheap commercially available El Wire drivers that use transformers are unacceptable due to noise and limited output. I have a fair amount of experience with micro controllers and very simple circuits but the design of an SMPS to drive El Wire is beyond my expertise. Using a Linear Technology reference design, along with the guidance of a few experienced forum users, I have developed an LT Spice model / schematic that I would like reviewed, validated and adjusted to meet my project requirements. Upon successful validation of the design I would like an Eagle PCB layout created with all the necessary files to have a PCBs produced by OSHPark. For this project I will provide - LT Spice circuit model / schematic including proposed components - Data sheets for all proposed c...

Hi i am looking for someone who can design and made fully functional prototype of similar controller like you can see in the video. In the video controller can control 3 axis but i am looking for 4 axis controller via 2 joysticks. Controller can be base on Arduino, Raspberry Pi or on any other micro controller base board or you can build your own. Must have: Software 1. Timelapse menu 2. Video menu ( i already have controller for 2 axis with very good video and timelapse software. My system is running on Arduino. Most of the function i like and would like to have on the new system will be specified later) Hardware: 1. Fully populated PCB board or boards 2. All cable connection with motors and with the batteries must have secure connectors so the cables can't get loose. 3. 2x joysticks 4. Large LCD screen ( not sure if touch screen yet) 5. Wifi connection with all 4 axis 6. Wire connection with all 4 axis 7. 5V and up maybe 24V ? 8. If not touch screen is selected some kind o...

The purpose for this PCB : will be to take in very small currents (small Mili Amps) to higher amounts of current around 1.2 or 2 Volts and store any energy it gets to be delivered to a lithium Ion Battery which will discharge current through USB connection. This is like a "power bank idea". The current is a random energy source so it is coming from a energy component which is not a direct current like an outlet but instead it is like a piezoelectric generator. What we are looking for in the PCB: 1. Surface Soldered Design 2. Creativity in selecting the right combination of Micro Controllers and Amplifiers 3. Keep at least 90% of the efficiency 4. Best made in Eagle. 5. Grounds in the design The board should also include LED indicator light to show when battery has been charged completely Also it should hold a USB (Female).
