I need to design a board with esp32-pico-mini-02 and two L6470h ST drivers to drive two 12v Stepper motors. The board must be as small and compact as possible and work at 12v and the controls to the motors must be read via rs485 or rs232 interface of your choice via micro selector. For more details after the acceptance of the work.
I am a furniture maker and I am currently building a wooden drinks cabinet. The cabinet is 450mm tall (low coffee table height) and I want to have a lift mechanism that will raise and lower a drinks shelf. There is not much room to allow for linear actuators, so I have sourced a mechanical scissor lift which goes from 95mm (fully closed) to 370mm (fully open). The lift is designed to lift motorcycles so it is very strong, but it is operated manually. It has a hex nut which drives a threaded bar. Using a socket and wrench, the operator can manually lift and raise the scissor lift. I am looking for someone to help me automate this lift process. I want the operation to be silent (no high pitched sound of electric motors). I want to control the speed and distance of the lift and for the lift ...
I need someone to design me a temporary traffic counting camera system. This camera system should be similar to those shown in the pictures and have the following features: 1) waterproof housing for battery, recorder and any other electronics (may just be a Peli case) 2) suitable battery to provide recording for 5-7 days (max) and 24hrs/day - battery needs to fit in housing 3) simple charging system 4) ability for remote status checking (battery level and recording) 5) ability to plug in a monitor to live view the camera during setup/mounting 6) IR waterproof camera(s) 7) be able to be built at a low cost The successful bidder will need to calculate battery consumption and provide a list of all components used that need to be available in UK. Drawings and instructions for assembly will...
we need a dsp professional ,long time ,good price (finally) Hi, we are using a algorithm ,which do noise reduction ,fft,etc ,it's working ok ,however ,it seems the noise reduction not so obivously, it seems to have big background noise. ok,below are our full requirements : we are developing hearing aid based on RSL10 ,it has arm coretex m3 mcu and lpdsp32 DSP .we use DSP to do noise reduction ,equalizer,etc first step is : build a good noise reduction .our DSP is LPDSP32, we have our noise reduction on LPDSP32 ,seems not good enough we need use LPDSP32 ,if one LPDSP32 not strong enough ,we will have 2 LPDSP32s
I don't have a file for my project, however I do have an example of what it is I am after and I also will do my best to provide a list of additional things need to be optioned/added to my example file to best satisfy my project's requirements. I am aware the circuit is very basic but I am more inclined towards the PCB for the space saving aspects than anything. All of the circuit components must be rated for 12VDC @ 10-15A. My circuit will be very similar to the attached file (nearly identical in design, as I have an all analog/some breadboard version of this proposed idea currently operational on my vehicle) with the addition of fused power supply outputs to the electronic ignition system, accessory power, both of which would be relay switched power feeds directly from the batte...
Hi, My project requires a raspberry pi tablet to accurately display power usage based on a utility electricity meters LED pulse, which pulses 1000x per kWH (i.e. 1-pulse = 1WH). > Communication between the light pulse sensor and the tablet shall be wireless. > The light pulse sensor and any associated equipment shall be easily removable, enclosed, and weatherproof. I require a cost-effective and reliable solution. All materials and components must be readily available from Australian websites. Thanks, Anthony

I have designed a PCB that is powered by 12v. It powers an esp32 cam, attiny chip and PIR sensor with a 5v buck convertor. I have added a circuit to the board for a "dark sensor" utilizing an LM393 chip, that will allow the main 12v current to flow when sun goes down. I need someone who is an expert with circuit design, to check and verify the "dark sensor" portion of my circuit, even though this is considered a relatively basic design.

Also have questions here that you can answer for now it's optional but will be asked in second round of interviews FPGA Questions Device we are trying to work with is XC7A35T-2FGG484I (Artix 7). We do plan on hiring you, we would like for you to answer these questions which will help us gauge how to structure the project. How familiar are you with microblaze? Once having microblaze cpu setup, is firmware compile time similar to other mcu roughly in the seconds or does it take longer? How familiar are you with design-reuse website? Is it feasible to program FPGA to act like a pass-through meaning say a signal from one side of the FPGA going to the another pin, effectively creating a multiplexor, could this work with high speed signals at the 1gbps level, and the serdes level I d...

Hello We need to design and fabricate a three phase AC power energy Meter. The design should use clip on current sensors. The output should include three phase current, energy per phase, and power consumed per phase. The information should be output over RS232. Information should also be displayed on an LCD display. More details in discussion with you, as we are not expert in AC current / voltage / power measurement, and are not totally sure about instantaneous power, reactive power, power stored etc.

We are working on a project to design GSM-Based blood gluco level notifier, this is an portable and mobile device to measure level of glucose in blood that effect our health in general. Blood glucose care is one element in the care blood glucose levels at home. Diabetes is increasing now that this will delay the process of examination of the patient in hospital. senior citizens need to wait too long for their turn. Those who are suffering from diabetes, consists than about the elderly, therefore, We are designing a project to facilitate the patient's health, going to hospital if necessary, since the patient will always checking glucose levels from time to time. Then a project designed to help patients control or determine the level of blood glucose at home and that information ...
