We are looking for professional help to design a compact power supply (like in the pictures). The power supply will be part of a customized PCB and has to meet security standards (EMC/CE/UL). It should be a transformer based switching power supply with an efficiency of >70% (e.g. based on OB2535). Input power will be ~80-250VAC and output should be 5VDC (~3W) like in standard USB-chargers. ...

I need to develop an infrared laser 'shield' to detect high velocity projectiles traveling through. The laser 'shield' will be mounted in front of a cardboard target, and will have to give an responsive feedback to the user-system of where the hit occurred. To ensure precision, the laser shield have to respond up to 150 000 times pr. second - as the fastest moving projectiles u...

i need someone who can develop software for a gps tracker. an arduino nano 3.0, adafruit ultimate gps breakout 3.0 and a mini sim800l are the components being used.

Hi, i need someone who understands a bit more about Sniffing GSM using RTL-SDR USB would like to know what kind of gsm/rf frequencies are around me. Spectrum analyzer software could be used. I have bought the hardware 100 kHz 1.7 GHz Full Band UV HF RTL SDR USB Tuner Receiver R 820 T 8232. Read Less

Designing a low-frequency filter with the following characteristics. Supply is +5V and GND. The filter should have a gain of -10 (inverting). (Gain in this context might sometimes be referred to as AC-gain) The filter should have a bandwidth of 1kHz. The filter should be able to drive a 100 Ohm resistor. You should make a design with an opamp (try and select one) and back your findings wit...

Hi there, I would like to control 5 stepper motors with an arduino to work in a specific sequence. I have no experience, and have never coded, but have a fun little project to do and have been told that it is an easy job for someone who knows what they are doing. The motors and drivers I have can be found in the below link. I do not know if the code or information they give in the link is comp...
