    I am looking for some help on a gripper application I have. I am using a NEMA17 stepper motor with drv8825 and Arduino Nano. Here is what I need: Home the gripper open to a micro switch on power up and wait for run input. When the switch is pressed and not released, the motor should make the travel forward 800 steps and reverse 800 steps and stop while touching the home switch. The circuit should wait until I press again the "run" button to go forward to close the gripper and reverse again to home switch. I need it to travel a specific distance. I only need the .ino file for this.

    1. This is a project based on a circuit board. I will provide the schematic diagram later. In the picture you see a BLE module, but I will try to add one more. 2. The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 str...

    I need a North America Based PCB Designer to create a Gerber file for a flexible PCB which is a voice Coil used in vintage Loudspeakers. There are no electronic components on the board, it’s nothing but one long circuit trace in the shape of a Coil, and it is 2-Sided, with 2 VIA’s to route the Trace/Coil from one side to the other. In the final product this is mounted in a Plastic Frame, and its function is Planar Voice Coil used in an Audio Midrange Driver. (see photo’s). The Deliverable is a Gerber File ready for Production, and there may be a couple revisions as the project progresses.

The circuit or the IC seems to overheat (or get almost dangerously hot) when charging at 1amp. It is also supposed to have reverse polarity protection. This doesn't actually work, the circuit gets fried if batteries placed the wrong way. 1) there will need to be a better design for the battery circuit. I require 2 to 3 amp output. I also need at least 1 amp charging and reverse polarity protection (without that dodgy IC (tp5100)) There is supposed to be a latching circuit for turning the device on.
