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.

I would like to carry out a small project. engineering of a product + design of printed circuits + verification of electrical circuits, making a prototype + welding of electrical components (about 50 electrical components, plc, resistors, capacitors, etc.) what would the cost be 2-3 weeks

Looking for a circuit and PCB designer for an IoT purpose. We need someone to design the circuit to withstand a harsh environment, such as high heat and humidity because in the end the device will be installed in a vehicle (Car). The requested design will be the initial one,

Hi, We have made a board with LORA. It is the main communication and control board to which other sensors are connect.We have some problems with the power circuit of the main board. detailswill be provided to shortlisted candidates.

We have a electric car charger we need a app to work with charger to start stop charger give charging data time charge history etc.
