Multiple Bluetooth Beacons will be moving in an indoor open-space. Through Bluetooth-Wifi gateways (iOT-gateway) the accurate location needs to be identified on the virtual map of location. It will be sent to the dedicated server.

you should know about ssd, hdd etc. you will be doing virtual labs for my project which starts very simple i.e to attach a monitor to HDMI etc but later on its more complex.

Hello, I’m a huge fan of the 20” iMac G4 model. I was wondering if you guys could customize it for it to be used only as a monitor but keeping all the looks to be able to just connect my Mac Mini and use it as a modern Apple computer with that iMac G4 “shell” if you could say so. I know graphics won’t be great compared to newer models but I really don’t care. ...

I am looking to have a small mini microphone built with bluetooth capabilities powered by a lithium ion battery. I would like one built along with a full build order.

I am looking for someone to design a simple high side PWM circuit. This will be running at 12-15vdc and could theoretically have a load of 15A max. It can't be low side because the negative terminal of my PWM controlled device is grounded to the frame. I prefer Kicad, or Fritzing as those two are easiest for me to customize my board layout in. If you can make the circuit entirely using digike...

I am using arduino mega 2560. I have a master arduino and a slave (display). They are communicating over SPI protocol where display expects the master to send data at 50 KHz i.e. the SCK pin from master to slave should operate at 50 KHz instead of buit in 16 MHz clock. Is there a method to reduce the clock frequency ? Altrernative method (no preferred) would be to generate a 50 KHz signal using ti...

In this project, we are collecting the data from a sensor and converting analogue data into digital using an ADC which is interfaced to a processor using SPI interface. The requirement is to collect the same number of data points every second which is equally spaced with minimal noise from sensor and ADC. Information about the ​sensor, ADC and micro-processor will be discussed in person.
