Being able to use Janus Gateway to manage all the video and audio streaming of all the Raspberrys in all the small cars would be a better, more elegant, cheaper (in the long run) and better performing solution. The Raspberrys are connected to an intermediate circuit to control motors and servomotors through the GPIO port. Each one controls 4 motors and 2 servomotors. I am sold some kits to assemble the small cars, although you have to buy the Raspberry, the USB microphone and the batteries separately.

So i Ask for: 1. Add a transistor circuit to supply 5V to the modem (from the lm2596 regulator) when the ESP32's GPIO commands. Add it to the current version of the schematic and PCB board layout. 2. Do the fixed-5V circuit, according to LM2596 datasheet, in the current schematic and PCB layout. Find the main components (1. transistor; 2. coil, diode, chip regulator) in LCSSC Electronics () so the footprints of the PCB match the solder pins of the packages.

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 Delive...

...accurate 2D CAD drawings. The job is straightforward: turn my sketches into a finished floor plan, then layer in basic electrical and plumbing layouts so the set is ready for permit discussion and contractor pricing. The space is compact but it still needs to show a living area, sleeping zone, kitchen, and bathroom. Because this is for residential use, code-compliant fixture spacing and logical circuit runs are important, yet I am not after a full MEP engineering package—just a clear, well-labeled schematic that a builder and an electrician/plumber can follow. Please work in AutoCAD, Revit, or a comparable drafting tool and deliver: • Floor plan (scaled, dimensioned, room labels) • Electrical plan (outlets, switches, lights, breaker panel) • Plumbing p...

...the performance targets I’ll spell out for each task. Most assignments revolve around algorithmic problem solving—think classic contest-style challenges or tighter, system-level routines that have to run quickly and use memory efficiently. Because these projects sit inside my broader electrical-engineering coursework, I’ll occasionally ask for help translating equations into code, checking a circuit calculation, or making a quick tweak to an existing AutoCAD drawing. When the workload peaks, I may also hand over some structured data entry or light technical-support questions (typically Windows or EDA tool hiccups). If any unfamiliar topic comes up, I value a fast learner who can dive into datasheets or docs without constant nudging. What you deliver: • Mo...

.../ consultant to refine the entire circuit design. I already have a rough block diagram and basic requirements; what I’m missing is a rock-solid schematic that can be taken straight into PCB layout. Here’s what I’m looking for: • Validate and optimise the topology (full-bridge or push-pull—open to your recommendation) for a pure-sine output. • Size and select magnetics, switching devices and gate-drive arrangements so the design runs cool and efficiently at 500 VA. • Provide complete schematics with all component values, protection circuitry and control logic. • Run SPICE simulations (LTspice, PSpice or similar) to demonstrate THD, efficiency and thermal margins under full and partial load. • Brief notes on E...

Our infrastructure is ready for a major uplift: I am replacing a flat WatchGuard/Ubiquiti environment with a full Cisco Meraki hub-and-spoke SD-WAN. The topology is straightforward—one headquarters that will act as the primary hub, a DR site that will serve as a secondary hub, and four branch offices that will connect as spokes. Here is what I need from you: • Design a Meraki architecture that introduces proper VLAN segmentation, Auto-VPN, traffic shaping, and advanced security while mapping cleanly to the existing IP ranges. • Produce a configuration set for MX security appliances, MS access/distribution switches, and any required SFP or PoE considerations so the cut-over is as close to “plug and play” as possible. • Create and document a ...

The M of "marketing" and the A of "agents" are the center piece designed to inspire artificial intelligence concept in a bright red color easily readable on a black or white background. the same M and the A should connect on the center. the LETTERS "" of "" are the same bright red color of the "...

I’m an Electrical Engineering student and I sometimes need an extra set of expert eyes on my coursework. When a problem set, small project, or concept gives me trouble I’ll send you the questions or brief and expect a clear, step-by-step solution that also teaches me the underlying reasoning. Most tasks revolve around mainstream Electrical Engineering subjects—think circuit analysis, power calculations, or introductory control principles—so a broad foundation is essential, even if we end up focusing on just one of those areas at a time. Deliverables for each request • A worked solution in Word / PDF with every step shown • A concise explanation of the theory or method used • (When relevant) simulation or code files from MATLAB, Multisim, P...

...create the resistance by moving oil from one side to the other side of a double rod small cylinder, through a controlled size orifice. I tested it and it works well and very smooth. I have already done the mechanical design converting the rotational motion to a linear motion and it’s in production already. We must cater for a right-handed and a left-handed swing. There will be 2 models. The one is totally manual and the other electronically controlled by a proportional flow control valve driven by a PLC operated by a UI. The manual unit is simple for me to build using this circuit: Let’s concentrate on the electric Robot ONLY. I found the valve that I want to use here are the specs and the manufacturer’s details.
