    PCB design, schematics and layout needed for basic stepper motor function. Our goal is to have a designed circuit board that will be used to drive an Adafruit reduction stepper motor (or similar motor) at exactly 1 rpm. We currently use an arduino, with the reduction stepper, but would like to create our own circuit board as a more cost effective solution long-term which could possibly fit in a smaller footprint and allow for a more durable and aesthetic build. Ideally the circuit board can be battery powered and contains a flash storage to upload a basic code that ultimately drives the motor. We are open to alternative ideas for how to design a system to operate the motor at 1 RPM. NDA required.

    Hello there! I have been in business for 6 years enhancing ladies eyelashes with the latest beauty trend, "eyelash extensions" When a lot of women in the beauty field service women we use a bright lamp (see in uploaded pictures) over the clients head. This allows us to see much clear. Another thing we do is fan the eyelashes at the end so they can dry. What I wanted to create was a 3 in 1 glam light that benefits the technician and the client. Three settings: 1) A light with 3 different brightness 2) A fan - When the technician is done set the fan and let the client relax instead of using a hand fan 3) Infrared Sauna red light - This red light has so many benefits that every women would love. When they are laying down for 60 minutes to get their lash service done why not add in a facial treatment and allow the technician to make extra money.

    My electronics knowledge is very limited but I'm trying to build a light setup for a 12V car. I have six different lights that need to be able to flash or stay on continuously. The lights will be controlled by 12V SPST switches. 1. Two headlights that will either do alternating flashing or stay on continuously. 2. Two Fog Lights that will only do alternating flashing when the headlights are alternating flashing. 3. Two taillights that will either do alternating flashing or stay on continuously. a. One switch should turn on both the headlights and taillights in continuous mode. b. One switch will turn on the alternating flashing of all the lights.

    Hello - I need to make a PCB that will have a total of 8 Solid State SPST relays, an Ardiuno nano (or similar functionality since I'm only using the digital pin functionality), 4 LEDs, and sturdy mounting connectors for a wiring harness to connect the following: Solar Power Wires, Lithium Ion 18650 Battery stack, Solar Battery Charger, Car Battery Charger, Wall Battery Charger. You could build in the Solar MPPT charge controller into the circuit. I can get single line diagrams for all of this. Please let me know your thoughts. I would like to have milestones for a gerber file, one for the software, and then a milestone for a tested fully functional product. Please let me know your thoughts. I already have the arduino code written and this system is functional, but I want it all integrated into a single board.

    CALIBRATE 7 ENERGY METERS We have 7 pcs of energy meters, type EH10-DIN Carlo Gavazzi . The 7 energy meters need to be calibrated. Not via electronic programming, but by wiring up at a high consumption cable. The readings need to be higher then they are now. The maximum which needs to be added is +- 20 000 kWh. The various 7 meters need different readings (which we will inform in detail) We can wire the energy meters in series on a small board, so they can be installed on a high consumption cable (max 32 Amps), in order to read the specific amount of kWh. We can deliver a small board, with the 7 meters installed (including the informatuion of which meter needs which specific readings) and 7 buttons to stop the meter when it has reached the specific reading. The meters can have a maximum of 32 Amps. We need to know how long it will take before this job can be done. So you need to know exactly how much kWh passes through the cable. We can pick up the small board when the specific meters have the specific readings. We would like to have the job done asap. We would like to have daily reports of the readings per email or whatsapp messages. Transport costs can be taken care of by ourselves. Please send us a price for carrying out this job.

    Hello, I need someone who had experience before in connecting Keysight Osciloscope to labview or Matlab and can figure also how to control a motor there. What I'll be needing is just to get the motor to one place and make several steps according to the step size i make automatically while getting the data from the Oscilloscope on each step (Vpp) Please only write if you have experience with this before, I want it to be done relatively fast. I will give full access to my computer with the camera so you can work freely on the devices. (including a web cam that will be looking at the devices to see it all works out) During the weekend I'll be nearby if you need me to operate the device somehow. To make stuff easier, this are the devices: Controller: NSC200 - newport Motor: NSA12V6 - newport Oscilloscope: Keysight MSOX3104T

I need to be able to more the motor with step sizes I choose continuously or move to absolute value. Also, the direction of the moving is important to me. * should also think about the boundary conditions of the task (like the end of the motor move etc.) The main purpose is to read read the photo-diode value in the scope while scanning with the motor and it will be displayed and saved on the GUI. The work will be done by connecting to my Computer with teamviewer and you will have access to web camera to see what happens. I'll be close by, if something happens and you need me to turn off and on the devices, I can. Before you submit your proposal, check that you know how to work with Keysight MSOX3104T and the motor NSA12V6 with NSC200 from newport.

    Our company specializes in global water feature manufacturing and design. We have a number of consulting projects (including overseas) which require a BIM Revit specialist to generate models and dwg packages with our production team. Mechanical, electrical, plumbing knowledge is a must. First consulting project requires as-built equipment room modeling in AutoCAD Revit. We have a person that is conducting the survey, the specialist requires to work with that info and revise the existing model. Second consulting project requires BIM Revit specialist's involvement during design development and tender documentation phase of multi water feature project. Need to work closely with senior designers and CAD drafter to produce necessary dwg packages. Ideallly, I would like to work with one specialist on both jobs but that will be determined upon completion of the first project. I would prefer to work with a local freelancer if possible for ease of coordination. We are located in Toronto Ontario Canada.
