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...

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...

I need some home automation advice from an expert to set up my AC with my Solar ouput. I want for my AC heating/ cooling system to turn on when there is excess power being exported to the grid from my solar system. I have: - 5 Tado smart controllers set up with 5 AC split-system units (synced & working well) - 10kW solar panels with 10kW SolarEdge inverter and 10kW SolarEdge battery - SolarEdge monitoring application - Google Home Assistant - SmartThings Hub - Tuya Gateway What I'd like is for when I have excess load going to the grid, my aircon systems turning on. I'm not sure what the options are to do this, however I do know the SolarEdge app tells me real-time how much I'm exporting to the grid, and I'd like to use that ...

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...
