Hi Bulent V., I noticed your profile and I see that you created a EV1527 based RF Receiver PCB. I am looking for a EV1527 based 433Mhz Transmitter schematic (preferably through EasyEDA) that I can use through third party websites like JLCPCB. The purpose is similar to creating a remote like the Amazon link Let me know if you've a ready-to-use schematic available including the antenna positioning in the PCB. Thanks
Hello, I need someone who builds a model of an existing motor driver plus motor in LTspice. The basic schematic is attached. The model will be the basis to design filters, which means that it should be accurate regarding the implementation of the mosfets, the motor and the power cable.
I'm looking to convert / scale down my existing iPad audio app to the iPhone. I'm assuming that converting or referencing old code will be of more help than starting over from scratch. I have a fairly clear vision for the new iPhone app, and also looking into the future for Android and / or Web application as well. The app is a L / R stereo, sine wave frequency generator. The goal is to modify existing code, and use UI/graphics from iPad version. The app was built using X-Code / Objective-C / C++ / Core Audio API ?? Ideal Skills... • Familiarity with basic Audio functions • Ability to handle basic UI graphics / layout • Familiarity with Apple TestFlight • Familiarity with Apple review / submission process • Be willing to sign an NDA Patie...

Please read these instructions carefully. Do not bid if you haven't read them! You must take the design we provide and simplify it accordingly, then share with us the final Kicad schematic, BOM and PCB. This is not a complicated project as you simply need to simplify an existing design.
...pinsocket footprint for nano. Kicad version 6.0. Schematic requirement: All symbols is required to have: Digikey part number/ DPN Manufacturer part number / MPN. PCB requirement: 2 layer pcb. Only 45% bend for pcb traces. Rounded corners, radius = 2.5mm Corner holes, radius = 1.5mm max size: 60mm x 90mm Componet requirements: Arduino: Step stick: Power regulator 7-12VDC: For input voltage and output to stepper motors, spring loaded contacts are required. Type Waco or Phoenix contacts. Project structure: All Schematic symbols: project_lib/lib_sch/tmc5160.kicad_sym 3D
Scope of the project is to power two seperate PWM motors via CAN BUS. We will need to filter and read only two specific CAN ID's, and depending on the CAN value our logic will drive two separate PWM motors. The CAN data will need to be converted from Hex to Integer and then to PWM value based. Using STM32 controller and Arduino IDE. Utilizing J1913 protocol Must be located in USA and sign NDA agreement.

Freelancer MUST have their own ALTIUM Designer licence!!! A PCB (4 routing layer) for a magnetic encoder with AFE, MCU(STM32), BiSS-Driver is needed. Schematic, DRC rules, PCB shape and constraints are provided. Not complex but noise and EMC sensitive. BOM and above Link relates to predecessor. Changes are: Slightly different PCB shape, AFE to bottom side, connections to MCU
I have a nearly complete schematic that just needs a little tweak and a professional look over. I have also placed connectors where I would like them and just need you to route all the traces and connect everything. For reference the board is to be manufactured through JLCPCB so if you use EASYEDA its a bonus. The board is designed to be the same size as the compute module at 55x40mm and 4 layer. It has 2 camera connectors, a USB hub, multiple SMD Headers. It also has a STM32F405 on board with various sensors. There is a potential part 2 to the project, which would involve laying out another PCB from an existing schematic. I have attached an image of a prototype board I have had made, it just needs condensing down to the above dimensions.

We have a custom built Unreal Engine 4 from source. We would like to add animations to the characters (actors) using code only (without using UI). The application we have does not have a UI and is all done programmatically. The basic animations like Walk, Sit, Stand, Dance, Wave needs to be added and then integrated into the existing code base. If you have experience in building Unreal from source, worked before with gRPCs and conan-ue4cli before. This might be right your street. Please only place a bid if you have deep knowledge of the above, as the project demands experience and creative approach.
...circuit produces too much heat, and does not charge the battery fast enough. We would like to replace this with a dedicated li-ion charging circuit which can supply up to 1A, from a typical "12v" (up to 21v) 50W solar panel. The task will be to design a schematic. We will incorporate the schematic into our main design and we will do the PCB layout. You will need to choose components from the JLCPCB catalogue. Using the EasyEDA design platform will probably be easiest for integration to our project. The output of the task will be a schematic and a BOM, with secondary part options for each primary component (to be used if stock levels of primary component are low). The design will need to be compliant to UKCA and CE standards for EMC interference, and cho...

-Design schematic that produces a layout F=A+B or F=A*B and show DRC to be done in electric -Cmos design -Transmission gates etc.
It doesn't have to be GREAT quality, but if you have a mic that works. Lines provided after acceptance. It is a french new wave parody. It is a comedy, but the lines are delivered seriously, sort of like what you'd see in Breathless, Cleo from 5 to 7, or other films made during that time period. It may have 1 adult themed line thrown in, as a joke, but generally everything is to do with a voiceover describing someone else. Skills: speak in french. I need a female voice. Il n’est pas nécessaire que ce soit une excellente qualité, mais si vous avez un micro qui fonctionne. Lignes fournies après acceptation. C’est une parodie français new wave. C’est une comédie, mais les répliques sont livrées s&e...

We need a logo for a Spa and Surf Camp village. The logo has to integrate a Lion and a Wave from the ocean in the background as in the example. We have to clearly understand have the idea of Surf / Ocean and Spa village. The final style has to be very close to the mockup. We want a lion as main icon. Close to this lion icon but better drawn. You can change the colors but we are pretty happy with this range of colors. Gold / green. You can change the font. Other ideas of design are welcome. Make something modern, original and unique. Thank you.
Hi, I am Tapan Patel. I am a civil engineer and I work as project management consultant, WFH in Brisbane Australia. I am building my new Family home in Mansfield, Brisbane, Australia. After Listening to family requirements and using my own concept for my dream home, I "tried" to prepare a simple schematic design on AutoCAD. Family approved inital draft So, I completed a draft Ground floor design and hired a local licenced architect to work on my concept finalise final drawings as per council requirement. Once I received the drawings set from him, I found myself disappointed in my own design. I found façade very ordinary and missing character and artistic build up, for a corner block home. The local architect cannot assist with interior designing or landscape desi...
