...web browsers. Developers should be skilled in HTML5 and JavaScript, or be comfortable using other programming languages or frameworks. Project Description: The Bubble Pop Hangman game will be a web based game that can be played on desktop, set in a simple ocean scene with a stick figure holding onto strings of bubbles (like a bouquet of balloons). The user is able to take a photo of their face/upload a photo which becomes the face on the stick figure. The objective of the game is for users to guess the hidden word by selecting letters from a word bank, before all 7 bubbles are popped (each bubble accounts for an incorrectly guessed letter), or before the timer counts down to 60 seconds. Categories are available to choose from. If the player loses the game, the stick fig...

Hi, I'm looking for someone that can design a PCB for me, here is what it needs to do. What I need is a pcb that has 3 individual + an - inputs of up to 20v dc The 3 inputs are individual 18-20v lithium batteries. The 3 inputs will need to have there own replaceable 10Amp fuses. I need the 3 inputs to have their own low voltage cut off to save the batteries when going flat. The cut off voltage will be 12.4v. They all need to be independent because it may only have 1 or 2 batteries connected at the time. Maximum load 10amps dc The low voltage cut-off needs to be Automatic reset once that battery has been removed from the product. The output need to be a single output Out of the output I need a step down buck converter The 18-20v batteries need to be stepped down to ...

There is a GitHub project that uses this pool pump unit but it seems my pool pump is newer than their pool pump. I built the PCB and the buttons to control it do not work as they should. I am unable to get in contact with the original coder for this project. If you can read and understand the code on their GitHub page then I would like to work with you. There is a lot of other stuff in that GitHub code but the main part I am posting this project for is to read and write to the main pool pump pcb. The project is currently in Visual Studio Code using the ESP32 IDF/PlatformIO Core. The source code compiles just fine and I am able to flash it to my ESP32. It can tell the pool pump is in standby and therefore I know it can read/write with my current po...
