I am trying to communicate with a mobile phone with esp32 esp32 captures the water level of the fish tank and the humidity of the flowerpot and transmits it to the mobile phone. Adjust the water level in the fish tank by looking at the data displayed on the mobile phone and water the pots. I have an esp32 and I know how to do some soldering I need an expert to help me Please put ESP32 in the first letter of the

Hi, We need someone who can design electronics for our product. You need to review product details, select sensors according to need and design electronics and PCB for it.

Looking for a simple design for a simple ventilation system for 23 affordable rentable workspaces in Uk, each unit is 7.4m x 3.5 x 3.2m and on average will have 1 to 2 people working in them. I am looking for the calculation on fresh air in and extract. So I can plan the ducting sizes! Or ever better if you can advice on the ducting, I have attached a layout of the run of the ducting it is on the 3 page of the floor plan

I am working on a hand held device which has a button and a power toggle for being used by user. I am looking for a thoughtful designer to create a finalized robust enclosure for manufacturing samples which are clean, beautiful, and thoughtfully designed I would like the desiger to focus on how the user buttons can be integrated into housing in a creative way. Current model is little sloppy and “prototype”. Need industrialization and thought design with unique solution. I minimalist bold designs which are simple, useful, and reliable.

An year ago I started developing a custom DDR4 DIMM module as a hobby project. By now, I have done the following: 1) Complete schematic design in Altium CircuitStudio 2) Complete footprint design in Altium CircuitStudio. The DDR4 ICs' footrpint pads are 0.35mm in diameter. 3) A list of signal classes (as a screenshot from Altium Designer, since I do not have a copy of the software) 4) Complete SPD programming kit - so that we can test the manufactured board immediately. I have not done any fanout or rules configuration, since I do not think that Altium CircuitStudio will cope with the length matching and parallel multi-routing properly - specifically for a DDR4 project requirements. What I need now is the following: 1) Route the PCB on 6 layers as per the JLCPCB capabilities. Note...

hen an IGBT or MOSFET are fully "on" they are known to be saturated, when they exceed their maximum current ratings they are known to "over saturate" which will eventually cause failure of the device. While IGBT's and MOSFET's are used for very similar applications it should be noted there are two main differences, the MOSFET tends to lean towards high frequency low-power switching whereas the IGBT leans towards lower frequency and harsher switching conditions, these are just the common assumptions. Due to the fairly ruggedised features of the IGBT they normally have around a 10us short-circuit capability and a higher voltage rating which makes them a lot easier to protect. The MOSFET particularly due to their lower current density ca

We have a working PCB with unknown firmware, we need to replicate the firmware.

We have 2 different board which has same SoC RK3566. We want to run this page Ubuntu image on this board. They all have same components. But Firefly image does not work on CM3 Board. So, we need help to understand what to do to make that ROC-RK3566-PC Ubuntu image work on CM3 Board. We have both PCB so we will try and release payment.

Hello, we had to change our original project, so now we are going to order something a little different. We need a PCB so that it can control an electropump, a solenoid, a safety float and, in addition, it has a safety system to prevent the opening of the box that contains the pcb, that is, if someone opens the box, I want Let me know via wifi or via Lte. It doesn't matter what everything is developed with, it can be arduino or whatever.

I need a simple audio hardware design/schematic to manage 8 zones of already wired left/right speakers in my home and two out by the pool. I think I would like a page on my iPad and iPhone which gives me all options of what music I wish to stream, (only one stream for all 8 zones at a time). Off/on for each zone, and volume. Do I simply need an app, a good amplifier, solid wifi connection, smart speaker selector…? No problem if this isn’t the type work you do. Thanks just the same, Steve

Login to our online learning portal will be provided instantly upon enrollment. The portal will have video lectures, tutorials, and quizzes required to build the PCB manufacturing project. Kits are well tested and shipped to your doorstep in 24 Hours. Use the kit along with the online portal to complete the project at your home itself. You can enroll for free demo to understand how it works better. Pay only when you are confident and if you like it! You need to complete the project within 45 days of enrollment. Generally, the project would take 16-20 hours to complete.

We are developing an app similar to Square payments but locally for our domestic in-country use. Hence, we are looking for a hardware engineer that can design, develop and manufacture at low cost a card magnetic strip reader attachment like the one used by Square (). We will appreciate a low-cost production. The one sold by Square is for $10. We would like something similar in pricing. Please bid with your: 1.) Design and development cost 2.) Manufacturing cost per device We will sign up for a long-term contract agreement to purchase from you. Please sub your individual / company profiles together with your past work portfolios.
