    Very knowledgeable in Altium layout. There were a few miscommunications, but we worked them out. He would not start working project until he was paid 75% of total project cost (milestone funded and released). Also, he would not release Altium file until all payments were made. However, this may have been because I was a first time employer. He found some of my mistakes and corrected them, and he delivered a quality product.

    Project Description:PCB layout project for an adjustable voltage board. Layout must be done in Altium Designer, and compatible with my version (AD 12). The board is 4" x 6" with connectors on two ends (see attachment for details)...

    Complete details are provided in the attached PDF.This project requires the design of a small circuit board to convert RS232 to RS485. The device is to be port powered from RS232 and designed to mount on a particular set of screw terminal blocks.The project requires delivery of schematic, BOM, CAM, and PCB/PCBA assembly documentation. Firmware source code is also required if a microcontroller solution is used.Please provide relevant examples of previous work.

    The job is quite simple. You will be required to be primarily working within the Altium Designer workspace.This job will be an ongoing role. So the first job may take a little longer, but each job will be following the same proceedure.Sub divisions of the job are as follows.1) Enter schematics from the web and PDF files you receive. Including BOM.2) Build library items and footprints from a previous gerber package (ie reverse engineer) Once of only 3x parts.3) Locate web datasheets for IC"s and import as library items inc footprints4) Create simple Schematics of PINOUT arrangements, for example ATX Mainboard Audio and ATX USB headers.I will upload the Spreadsheet today, and feel free to have a quick look. Once you apply, I will send you the complete package for review. The budget for this job is below our normal rate, however next payments will increase if the work is above average.For the first job, payment will be on completion. Further work will be on a 50/50 payment upfront.

    The POS (Point Of Sale) Data Logger is similar to a portable magnetic stripe reader in that it logs data and can be used for memory back-up in case of power failure. This device quickly connects in-line on the POS terminal. Iam sure you have seen these POS terminals in just about EVERY store & some terminals have a computer-like keyboard with a built-in credit card reader, others have a separate credit card reader and some even have a credit card reader with a PIN pad where you enter your PIN # if you are using a debit card. Iam looking for a person who can convert a keylogger to Point of sale data logger which can capture the card details when a card is swiped while at the same time retain the pin number when it is entered. I have tried purchasing these data loggers but they only work with a normal keyboard and do not capture the card information when a card is swipped on a point of sale terminal. Bid only if you are sure you can do this job.

    Program in ASM a small PIC with just 3~4 buttons, 1 x LCD (2 lines x 8 characters). Unit is basically a (very accurate) timer. Press button 1 and an Output will be high for XX.xx (setting 1 in flash) seconds, then off. Press button 2 and an Output will be high for XX.xx (setting 2 in flash) seconds, then off. Display time and count down on LCDCounters for number of cycles for button 1, number of cycles for button 2, total run time since reset, total run time (never reset), total kg (total time x constant that can be set). Other language options for menu and display.We only need well commented ASM code. No PC Board or samples.
