    7vdc buck regulator for Arduino Mega PSU 6 วัน left
    ยืนยันแล้ว

    We need a 24vdc in to 7vdc out - buck converter @ approximately 1.5amp to power an Arduino Mega / DUE. The onboard regulator gets hot if driven above 8vdc, so I want to have a dedicated 7vdc PSU that doesn't get hot like a traditional linear LM7812 does. I've used AL8805's in the past and even LM2596's, so am open to ideas as long as they're not end of life components which will be hard to source later. Just need a schematic and formulas for 24vdc in - 7vdc out. Milestones will be paid: 1. 50% on supply of the circuit details 2. 50% on completion of testing the circuit (will need 3 days to get parts and build it)

    Need to build a sensor that using two points could measure the variation of a small current flow (mili Amps) going through a material when affected by heat or pressure. Data must be send through a Bluetooth interface.. The device must accept some basic configuration and offer a simple protocol communication with the linked application through the Bluetooth interface. Even when the drawing shows a finished product layout, the prototyping could be done on any type of board.

    The Concept of the Project is:- There are few Photocopying machines : 1, 2, 3 ….N Each machine has 2 high temperature points (drum and toner storage block). Temperature sensors are there to indicate temperature values. Requirement is to capture these 2 temperatures from each machine every 30 minute. And, send them to a central web server using 2G GSM network for continuous monitoring of the 2 parameters. Thus the project involves: (1) To make an IOT board and connected to each Photocopying machine. - this board will collect 2 parameters values [T1 and T2] using Temperature sensors - the analog will be converted to digital using ADCs - digital data will go to a processor - processor will send these 4 data to GSM module - GSM module will send to Central server (2) ...
