    I need some assistance to design and produce a prototype simple circuit that will provide sequentially flashing LEDs for vehicle turn signal and brake indicators. This prototype will be used for evaluation and marketing purposes prior to any decision being made on manufacture.The person I"m looking for has done something similar to this before and can provide me with options for the flash sequencing, integration of multicoloured LEDs (red/amber), and particularly a good knowledge of how to design for cost effective manufacture.I envisage the finished item will have 10 sets of 3 LEDs, providing 10 positions that can be animated/sequenced.Please provide examples of similar work and I will forward you a more detailed description of the project.Thank you.

    I am looking for someone with micro controller experience to help me with a project. The project involves one micro controller that is powered by a battery (9V). When the chip is powered up, the micro controller will count off 90 seconds and then send a DC signal (although an 2.4Khz signal would be better) which will be used to drive a buzzer, unless a reset signal is detected or micro controller is powered off.It has been a while since I have programmed micro controllers so I need some help.Thanks,John

    I have technical indicators that are currently written for metatrader that I would like converted to esignal.? One indicator is a smoothed version of the ADX indicator and? the second is a Momentum indicator based off a moving average of price.? I want the indicators to have the same functionality and customizeable settings that they currently have in metatrader.? I will provide the indicators so the code and be converted from metatrader language to esignal language. It would be helpful for the coder to have knowledge of both metatrader and esignal scripting languages as well as some understanding of financial instruments.

    I want to convert AFL code of Amibroker to DLL plugin to hide original formula, and also to protect the DLL and making it hardware locked. I want to wrap the DLL with security, or license ,then it will have expiry date, this expiry date then can be set to 30 days, 90 days,etc. The result should be an executable file. When it run, can automatically install the DLL plugin to Amibroker directory.The default expiry date of the DLL can be set (e.g 05 days) , and can be extended through entering a long code in relation to the machine serial number.dont bid if you are not done this before

    Hi,Thanks for looking! I"m not proficient with all of the terms used in this field so please be patient while I describe what I need. I need somebody who is efficient with C programming or better yet, someone who has experience with Arduino libraries to program a Arduino USB micro-controller with an lcd interface attached. The controller will output a 4 digit code to a text file (or input field) on the computer. It will also output this same code simultaneously to an lcd screen that"s attached to the micro-controller itself. The controller will start at 0000 and run until it reaches 9999. There are a few other simple conditions that need to be implemented such as:Hit enter after entering the 4 digit code. Wait 16 seconds until outputting the next code.Begin automatically a short while after it has been plugged in to the computer.I have the majority of the code ready for a teensy 3.0 but need somebody to tweak it so that we can output it to the lcd screen.I will purchase the Arduino and lcd attachment after consulting you and seeking your advice on the best one to purchase and await the code to implement it. If it"s more suitable for me to send you the device, then I may be willing to do that too. Thanks for viewing.

    Hello our requirements:Sound to Light circuit Schematic and PCB layout for the following simple projects:We have a Basic version schematic (can be provided) for single colour: OVERVIEW12 Volt supply in and out so unit can be daisy chained. Output x 2 with a 4 way switch to control ON/ OFF/ SLOW FADE (using a Capacitor) / Bypass the Fade. With a sensitivity pot. Plus MIC pic up.The update to this is to add a LINE LEVEL INPUT 3.5mm jack with switch for for MIC or LINE IN option. Based on the current PCB layout.The end result for this project will be 4 versions:V1. BASIC Single Colour Sound to light, as outlined above.V2. RGB Output Sound to light with a range of selectable colour, using a mode push switch I assume this could be done on a PIC Chip.V3. RGB As above but with 2 mode switches, 1 to perform Sound to light colour, and the other to control the Static light colour- when no sound. Modes & colours to be discussed and agreed.V4. Remote control version - using off the shelf Remote control with PIC - To be discussed -we have an example of this.The RGB Version will be running approx 45 Watts at its max in typical use. But the need for a higher power will be required around 100 watt.All these need to be the same size (but as small as possible) for our production mold for the case.We have pictures of where inputs and outputs need to be for V1 which should help and components. Ideally a Freelancer with knowledge of DMX to SPi will become a requirements in the future for follow on projects. Although not critical at this stage.Many thanksJeff

    Hi, I need a solution based Microcontroller thatI want to transfer Audio over IP using a low cost microcontroller but it needs to be low latency!One master unit must be act as server/master.Other units must be client/slaves.I know there are Cobranet, Ethersound, Dante, Livewire and AVB2 is high-end and standardized solutions for this purpose on the market.But i need a basic & low cost solution for this puspose (not to discover Continental America again!)Requirements:-I2S over Ethernet using CAT5 or RS485 is considerable. -One server/client must be sent and receive audio bidirectionally (full duplex) with low latency.-Multiple receivers must use same cable (bandwidth)-Simultaneously one client could receive an audio stream, at the same time another slave/client could receive or send another audio stream to/from server/master.-Cost per slave unit below $30 is suitable!-Full finished project solution with firmware codes & PCB design files need!Cost of the solution is important! STM32 (ARM based) solutions wellcome!

    We need someone to design the electronic circuit to take the voltage values output from a piezoelectric sensor and input them through a phone"s headphone jack. The signal into the phone needs to be in a form that an app on the phone can read and understand. In addition, any power the circuit needs should be drawn from the headphone jack of the phone. We will need this design to be made into a PCB layout as well.

    I"m looking for someone to take an open source firmware for an STC-1000 temperature controller and adapt it to a different temperature controller. The firmware needs to allow the user to create different temperature profiles. Each profile has a specified temperature for a specified time period before going to the next temperature and time period.Here"s a link to the open source firmware that does a better job of describing how it works than I can.https://github.com/matsstaff/stc1000pI would prefer to be able to modify the firmware through a USB Microchip ICSP PIC Programmer instead of an Arduino. There is an attached picture of the processor of the target controller that I need the above firmware adapted to. I can provide more pictures and information at a later time.

    We need a 2-way P2P file sync utility that can keep directories in sync across the Internet on Windows computers, similar to BTSync, Hive2Hive, and Unison. It"s OK to start with an open source project like Hive2Hive, which is a Java library for developing file sync utilities. In fact, we would prefer to use the Hive2Hive library. We need no UI. We require:* Block based protocol - sync only the parts of files that have changed.* Support for Reverse NATThis utility will be used to keep two or more directories on separate Windows computers in sync across the Internet. As files are added and modified and deleted from one, they should be added, modified and deleted from the other.
