    Hi, I have a Chinese manufacturer ready to make my complete switch and logger, I was hoping you could alter things for a pcb layout that the factory will produce? I would like +- and RxTx located on one edge...component size can be as small as possible. If I show you the membrane design maybe can reposition the tracks/solder pads.On the supplied pdf I used a slightly larger pcb size, again tho smaller is better especially due to the fact it will be factory made.

    I have an assembly program that was originally written for the PIC16F690. It takes serial data in, process a specific number of bytes, and convert it to an I2C stream to a Master. I need someone to update this code to a PIC18F that has more RAM and is much faster, and in the mean time, process three times more bytes.

    I am looking for someone to take Solidworks part files and/or drawings and create CNC g code to run on a HASS 3 Axis Mill. I will set the XYZ 0 locations and provide details on the orientation and fixturing being used. I can also provide a list of tooling available for use, the material type and any other info needed. I would prefer these files be created with Mastercam x6 or 7. I will provide one project at first, one your program is ran without issues and to the correct specs, I will be needed about 10 files a week or so. I need someone who can provide a good turn around time, knows and understand speeds and feeds for CNC machinery and is trustworthy, I do run Mastercam and Solidworks myself, I know how long it takes to program these rings, I simply do not have the time to create the files myself. I am willing to pay more to the programmer once I am confident their files and communication is good, the amount listed is for up to 3 files, after that we will discuss pay increases. I have included a picture of the part types I need CNC files for.

    Require PCB layout completed via reverse engineering/ modify an existing design. The project is for a LED emitter driver. The exact emitter is best seen here: expectations:1. Supply PCB layout2. Supply detailed schematic print and component list/specificationsI will write the program. Job is complete when the schematics can be used to setup a bread board and achieve functionality. I am open to other design considerations and input.The design requirement are:1. PCB layout in 17mm diameter board as per 1122302 design2. Modification to permit 3 different switch inputs3. There are 4 "star" locations on the above mentioned board. These stars permit configuration changes of modes by grounding one star or another. The need is to allow one of the 3 switches to make this change "on the fly" rather than solder joint.4. IC chip (Prefer the ATTINY series) to be programmable. The layout should permit attachment points at each IC lead to attach cable connector to permit- On Board Programming of the IC.5. Must maintain the set 8-AMC7135 regulators or 2800 milliamp output currentOther specs: (As per specs listed on fasttech website for this driver)•Reverse polarity protection•Low input voltage warning: blinks once per second when voltage drops below 2.9V to 3V•Work with 1 lithium battery or 3 AA/AAA batteries•Works with Cree R5 T4 T5 T6 U2 MCE, and other similar LEDs•PCB height: As design dictates•PCB height (including components): As design dictates•No power spring required

    We are looking for an experienced individual to design a low cost Wi-Fi snapshot camera. Expectations:Provide initial design concept proposal (Components, Communication, and Data storage)Provide all deliverables submittal committed datesSubmit all deliverables listed belowThis bid is for a proof of concept design, we are looking to entertain a working relationship for the next design iterations Qualification and preferences of candidate•Experienced hardware designer•Existing Linkedin profile preferred•Elance profile complete•References if available prefered•Available to skype•English of french speakingOperation description:Power up: The self-contained board, on power up will automatically connect to the Wi-Fi network it was configured to. Once the system has powered up and connected successfully to the Wi-Fi network LED1 is turned ON and blinking only when data is transmitted. Action: The prototype board will have a press button. When pressed it triggers the camera to take a picture and automatically start the save process onto the cloud based virtual drive through the Wi-Fi connection. LED2 is turned ON from the start of the picture process up until the saving process is complete then it is turned OFF.Configuration: The setup of the Wi-Fi connection (Login, Password) and the setup of the cloud base virtual drive (target address, login, password) will be done by connecting a USB cable to the board USB connector and a PC USB port. A simple software will take care of the configurations steps. Software must be Windows 7 compatible.PCB needs: PCB maximum width is 1 inch, length is to be discussed when preliminary silkscreen layout is available. Camera must be attached to one end of the board. Details on test pads and additional solder point needed will be provided once BOM is accepted.Deliverables:Preliminary layout (silkscreen layout ok)PC application to setup Wi-Fi and virtual drive setting (location, login, pws, …)Configuration application software codeHardware software source codeBOMPCB layout (to be designed on free software preferably)Circuit Schematic (to be designed on free software preferably)Working prototype assemblyGeneral system characteristic:Prototype must have USB connection port for programming, debugging, Wi-Fi connection setup, virtual drive setup and configurationCamera (low cost surface or through hole mount camera; resolution >= 1 Meg, Color or Black & White type)Wi-fi connection (open to solution to meet low cost criteria)Storage: open to suggestions; ok to use any free online storage service for prototype purposePower: Prototype board power could be any off the shelf AC/DC transformer (AC: 110~240 VAC, DC: 3~6 VDC). DC power selection is at the discretion of the designer
