UHF Handheld Radio

A design/prototyping group is needed to develop a neuromodulation audiovisual wearable device. The device has the form-factor of a sleep mask containing LEDs and earbuds to stimulate the brain with light and sound modulated with brainwave frequencies. The device controls the light and sound in accordance with a waveform (stored in an SD card). Required key capabilities include electronic product prototyping, PCP design, embedded SW, signal processing, audio file, low power devices, 32-bit MCU, mechanical closure, wearables and ergonomic devices,…

I'm looking for an expert in Barcode Scan and electronics, I need a box with barcode readers inside this box to be able to read objects automatically. When I put one object into this box, this object should be identified using a barcode. This box should be able to identify this barcode in any position.

Searching for a specialist who has a little bit of free time and can design a scheme of properly working Address engine control unit with integrated LIFEPO4 battery (with protocol management and testing) on Altium (included library and Gerber files). As the confirmation, that the module works properly you will be asked a video demonstration, also the results of testing. If some materials are needed for testing the scheme - we'll cover the cost.
