    Logo design 6 days left

    We are a financial services firm that specializes in asset management and financial planning. We are looking to change the bottom of our logo. We would like to remove the circuit board look under the bull and the bear and replace it with a creative way to incorporate the letters PWP. We don't just want PWP dropped into the empty space we would like to see creative ways to incorporate the circle design.

The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder.

    This project is part of a medical device prototype. It is a 110V output amplifier, capable of delivering between 100-3000 watts into an 225 Ohm load electromagnet, operating at frequencies from 4-300 Hz. The ELF parameters made the oscillator circuit of special interest. A simple R555 chip setup may be adequate, though several may be necessary to for complex waveforms.

    I have a working prototype using Arduino MEGA, however, I would not like to use an Arduino mega for the final product. I would like to have the circuit converted to without it. It is a very simple project. Possibly extra work if you would like to design the simple PCB as well, of course I'd pay extra!

    I am trying to work out a bespoke electrical circuit for a slave / tandem heating system which includes a gavity fed standard Y configuration CH and HW gas boiler with a mid port valve and now a slave pellet boiler stove. The pellet boiler stove has an integral pump which activates when the water in the boiler reaches 70c. At this stage I want the system pump to be activated and water to be pump into the HW cylinder until the cylinder thermostat reaches 70c at this stage the mid port valve would activate both grey and white wires to dump ongoing hot water into the central heating. Importantly I want it to do this using the existing system pump, mid port valve and cylinder thermostat that is part of the gas system.

Due to high inductance generated by the electronic locks, it is necessary that the circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs. The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours. This circuit will be activated when the site is without power. To connect the ESP32 to the internet, a 4G modem is connected to the board. The board must have a female USB connector to power the 4G modem. The female USB connector must have a circuit capable of having its power interrupted by a command sent by an ESP32 I/O p...

    Hi all. Using the Arduino IDE, I need to use a microchip SAM L21 MCU in my circuit, with a Watchdog feature. Unfortunately , the watchdog setup is well documented on the SAMD21 chip (lot of tutorials and sample code online), but not on the SAML21, which differs on the internal clock used (if I understood correctly). So the project is the delivery of a functional watchdog code for a SAML21 in arduino, including any necessary original or modified libraries (a good library example of WDT library for the SAMD21 is ) You don't need to have access to a SAML21 hardware, just to provide a functional code that compiles with no error. Technical info : the Arduino board manager uses the following board library :

The simulation must contain one complete cycle of the counter and test all functions. It must show that the synchronous load really is synchronous and that the clear has precedence over load, which in turn has precedence over count enable. -Write a VHDL file for a two-digit BCD counter with active-LOW asynchronous clear, active- HIGH synchronous load, and an active-HIGH count enable. -The counter must count up from 00 to 09, then 10 to 19, and so on until it reaches 99.
