I am seeking a skilled Device Design Engineer to create a wire-heating device for my project. The device needs to be powered by a rechargeable Lithium-Ion battery designed to heat wire to a temperature below 100°F. The wire length is between 3-5 meters. I attempted to build a similar device using a steering wheel heating wire I purchased on eBay (0.03ohm) and a 4-cell 6V battery box, but it consistently overheats. Therefore, I seek an expert who can design a reliable and efficient solution. The ideal candidate should have experience in designing small and lightweight devices. The required voltage for the Lithium-Ion battery is yet to be determined, so your expertise in selecting the appropriate battery configuration will be valuable. Note: Any suggestions or alternative approaches t...

We need an experienced electronic engineer to review our current PCB design and address the remaining issues to complete the project. Our functional prototype has undergone testing, but we have encountered a few minor challenges along the way.

Additionally, we require assistance in incorporating an on/off switch into the design. This will involve the supply and testing of a new PCB. Currently, the system is programmed using Arduino, but we are open to suggestions for alternative approaches to enhance its performance. Our product utilizes a standard off-the-shelf wireless charger integrated into our custom PCB. The system operates on a lithium battery. The project ...

I am in need of a custom RF meter, but dont have any electrical skills. Therefor looking for an electrical engineer (project leader). Long story, in extremely short. I am needing to build an RF meter that can outperform an ENV RD-10. RD-10 specs: RF Frequency range 100MHz to 8GHz RF measuring range -60dBm to +5dBm RF Typical accuracy ±6 dB I am in need of a meter that can go beyond 8Ghz. Preferably 100Mhz - 90 Ghz. The issue at hand. ''Professional equipment'', like Narda for example, for political reasons; work with a low sampling rate (mostly 5/second sampling rate). I am in need of a high sampling rate (20.000/second sampling rate). Price is open for discussion. [Reposted due to freelancer error]
