High frequency electronics: signals, sensors and electronic interfaces to ADC make a 10 pages report with referances before 14/09/2017
We have a pcb that just light LEDs so it is very simple - the red LEDs light up with one polarity and the greens with the other. We have Gerbers, BOM and circuit diagram. The problem we have is that there is an error with the tracking so that it does not function correctly. The task is to fix the tracking and send us the corrected gerber. There is no need for a prototype.
I have a number of components and need to work out what is the sample rates that can be achieved. LED driver MAXIM drives LED. Photodiode gets reflected light, need to sample during the OFF time and ON time of the LED. Using on chip ADC from STM32L476RG - sample 6 photodiodes using only 2 of the ADCs (3 lines on each) Provide a report with calculations and reference to datasheet informatio...

Design a very simple and small circuit (pcb) for use as a 12-volt battery charger/battery back-up and hopefully based on the LTC1967 possibly using a pair of NDS8947 or equivalents. Only 3 connections: 12-volt (~14 DC) Power Supply In, ~13.5-volt+ out to battery under charge and ~13VDC+ to radio transmitter- Current draw capable of ~20 Amps+.

Project is a set of ear enclosed headphones for the hearing impaired for the purpose of hearing the television without using other hearing aids. Because the listener (hearing impaired person) doesn't wear hearing aids while using headphones to listen to the television, it is very difficult to communicate with the listener even if they take the headphones off because they're not wearing ...

We would like to build advanced RFID controller based on G400 SoM by GHI Electronics. This should be design based on existing reference board and will have very similar set of interfaces some links: [url removed, login to view] reference board: [url removed, login to view]
I have designed a small childs toy. My friend who is an aerospace engineer has put a system level design together but I need an Electronics Engineer to actually put it together and help me make a prototype.
have a project where i need to detect a person once they between 50-70cm away from an art installation. i would like to use the RCWL-0516 sensor but unfortunately i can not get the detection range less than 5m. I'm looking for some one to look at the unit and let me know how i can modify it to detect a shorter distance. The sensor will be triggering Raspberry Pi3 via it's GPIO pins
our in house built 3D printer needs to be verified that the electrical components are correct. as well as design the electronics blueprints for the machine. we are open to suggestions for new components.
