I need a high-fidelity mechanical model built in Simscape Multibody. The project calls for an advanced level of detail, so beyond the usual bodies, joints, and standard force elements, I will also require custom components or subsystem blocks where off-the-shelf parts won’t capture the real-world behaviour. Here is what matters most to me: • Accurate kinematics and dynamics that I can reuse for further control-system design and optimisation. • Clean, well-organised Simulink/Simscape hierarchy so I can trace each degree of freedom quickly. • Custom force or constraint blocks if the native library elements fall short. • Clear documentation inside the model (block annotations and comments) plus a brief external note that explains key parameters and any user-...

I have fifteen disassembled original first generation "cigalike" e-cigarettes waiting for fresh new cells. The spent batteries still have to come out; I’ll supply the brand-new replacements along with step-by-step instructions I’ve written from my own repair notes. Once each cell is tinned and soldered, the board and wiring need to slide back into the original metal tubes that I will ship with the lot. After reassembly I need every unit verified for both firing (making sure the LED end eliminates, and it produces vapor,) and charging. A simple functional puff/hit-to-vape check is the first pass, then confirmation that each battery takes and holds a charge using a charging USB that I will provide. If anything reads off, I’d like a quick note so we can decide whe...

I have a circuit idea that now needs to move from the sketchpad to a real-world prototype. The end goal is a fully built, ready-to-power-up PCB that I can use purely for test and evaluation. It is a basic esp32 temperature humidity detector with OLED. This is only to make a working prototype to test. I’m flexible on the technical route you take. Whether the design ends up single-, double- or multi-layer is entirely your call once you’ve balanced trace density, signal integrity and overall cost. The same freedom applies to board size, component selection and any IPC standards you feel are appropriate. What matters most is that the finished board functions reliably for bench testing and arrives with all the data. The project should be created with EasyEDA Deliverables I&rsquo...
