I need to incorporate the technology of a non-invasive electrical tester which detects AC voltage and lights up when voltage is present with a set of pliers. Below is a link to an example of the tester. The tester can read if a wire is live just by touching the rubber.   [obscured]  /webhp?sourceid=chrome-instant&rlz=1C5CHFA_enUS503US504&ion=1&espv=2&ie=UTF-8#q=Gardner+Bender+TesterKit&tbm=shop&spd=8774199084521156521 I need help with how the circuitry would work and where the technology would be placed in the pliers. I will need drawings showing exactly how it would work. Once I decide on someone to work with, I will share more detail and the sketches I have.

We have a custom Unitronics program that was written several years ago. The original programmer cannot be located and we need to make some changes to the code. Changes include the removal of some artifact legacy code that is no longer useful. Changing some user input screens. Changing some limitations to time inputs (ncrease the maximum amount of time a user can enter), and changing some parameters for how things operate. The program deals with time, temperature controls, and relay out puts to control pneumatic actuators and vacuum pumps. We realize that it can be difficult to go behind another programmer to make changes but if you feel you are up to the challenge, we are ready to get started. We have decided that this is best tackled as a per hour project since you have no fair way of determining how much time it will take. Please provide details as to other Unitronics PLC ladder programming you have done. Program is attached if you want to take a peak before bidding

I am looking for someone to add a very simple ADC function to my current working code. here is an idea on my current code i have a circuit that has an analog op amp circuit which is responsible of applying a ratio to an input signal via dividing resistors, and i have 16 pos rotary switch controlling 16 optocoupler to control which resistor is selected so the ratio can be different, now all what i need is some one that can add a working ADC so that it can control when the optocoupler is opened and when is closed based on the input voltage. i forget to mention that code i have is been made on CoIDE i need this adc code ready in 48 hours maximum. please Bid with a reasonable amount thanks

I need a custom board designed for the Atmel SAMA5D4 that should be relatively straight forward. I would like for the design to be done in Eagle, but that isn't a firm requirement. The board will have these types of components: 1) LCD connector for a 720p display 2) 256 or 512 MB of DDR memory 3) NAND flash (for the boot loader, firmware, etc.) 4) SD Card for the OS, etc. 5) Various regulators and filters 6) A few I2C/SPI/UART sensors 7) One or two debug connectors I have a good idea of what I need and this project needs to be done fairly quickly.

We have do execute electrical modifications on the Heathrow airport baggage handling system. It is our plan to subcontract the work to implement modifications on the lelectrical drawings. We would support redlined drawings and the eplan files. The documents can be handed out in our office in Heathrow, send by mail paper wise or we just email the relevant redlined pages. There is also the possibility to do the work in our office in Heathrow. We are about to produce the redlined drawings in the next 2 weeks and then we can give a estimate about the numbers of pages. The target of this description is to get first contacts.

I'm not sure how feasible or complicated this is, so I welcome suggestions or estimates from someone able to achieve it. Local providers preferable. I'd like to use the video signal going to a monitor and make it display only the pixels containing a particular shade of gray/luminance at a time, while turning on separate mood lights for each shade/luminance. This would be for an art project to add different color backlights according to the grayscale images that are being displayed. Similar to the typical color backlights in some TVs, but it will only show pixels of the same brightness on the screen at the same time, instead of the whole image. For example: 1- Monitor displays only the pixels with 0-10% brightness (for any image or video being played), and turns on a yellow LED strip mood light. All other pixels remain black. 2- Next, the monitor displays only pixels with 11-20% brightness and turns on a blue LED strip ... and so forth, until it displays the pixels for all luminance...

I have a custom PCB based around the Freescale i.MX6 that needs to have simulation done on its DDR3 interface. Depending on how that goes there could be follow on with the eMMC and PCIe interfaces being simulated. Must be done in Altium and then the files passed back because we need to run the simulation in house on our Altium installation. The design files will not be allowed outside of the United States.

Need a circuit than can track a pencil or similar type line as a device moves along it and sends signals to two or four stepper/servo motors or other position controllers to keep the device in line by compensating for any drift within 6 mm (or more). The device consists of an inner and outer frame. The outer frame is for large movement. The inner frame is for precision movement. The outer frame moves horizontally, parallel to the line and is not electronically controlled. The inner frame holds the tracking unit. It is the tracking unit that adjusts while the outer frame is moving. If the outer frame begins to move out of the range of the inner tracking unit, an indicator comes on indicating the direction to move the outer range otherwise the inner frame adjusts automatically to maintain position. The inner unit can move via the servo motors or similar position controllers +/- 3 mm. This is the minimum acceptable range. Greater range is desired. Summary: Device tracks along a line Co...
