Update: After a long discussion with my insurance agent, I've removed the design insurance requirement. I am looking for a electronics design partner to create two printed circuit boards for a robotic lawnmower. I am price conscious and interested to learn about any price trade-offs that are available. I believe I want two boards as follows: The base station should contain a PCB that is AC powered using an external transformer. It should have basic location capabilities, an RF transmitter, a modulated infrared light, and provide power to charge the robot unit. The robot should contain a PCB that is battery powered. It should contain a micro-controller, multiple motor drivers, battery management, GPS capabilities, an RF transceiver, and infrared sensors, a small LCD touch screen, sound generation, and several sensors including one or more cameras. These boards should be in compliance with relevant US and EU regulations and standards. You should produce basic software for the sy...

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...

[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...

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...

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...

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).

Revision 3.1 / January 22, 2015 We are seeking sources to design and/or to produce a custom micro-controller (MC) based Printed Circuit Board (PCB) with very low profile and ultra low power consumption that will be embedded into a series of custom medical products. Various products will have different functions and features; however, a single multi-function PCB will be used for the entire product family. The PCB must excite and condition signals from (4) precision load cells and then convert this data into computed metrics and stream the results to a host computer over USB and optional Bluetooth. The PCB must also drive an optional auxiliary user interface consisting of a custom membrane switch with LED indicators and LCD display for certain stand-alone product functions. 24-bit ADC with simultaneous sample and hold of 4 single ended channels at 100 Hz minimum sampling frequency is required. The MC must be capable of streaming the computed values continuously in near real time...
