    Help understanding this car seat heater diagram

    Without some form of feedback - provided by the thermistor and controlled by the 'box' - the heating elements will just continue to make the person in the seat hotter and hotter. That person would have to regulate the heat themselves by switching the system on/off. For the passenger this isn't...

    The blocks labelled 'seat heater control' are the stumbling...errr, blocks. Switching, temperature control and safety protection (in case of over heating) are all achieved by those blocks via CANBus signals and your vehicles main computer. The only way you can 'bypass' them is to access the...

    Help how to build a dc voltage interrupter to control power on and off time. PWN not sutable.

    I see nothing 'vacuous' in trying to KISS or simplify a solution. The current 'insistence' that everything needs to reduced to a microcontroller and code is wearing. For many people this would mean learning to code, obtaining the hardware to load the code to a processor, buying the processor...

    Consensus never was and never will be 'science'. FACTS constitute science and experimentation to verify theory is also paramount. Not one single climate computer model actually models the rise in temperature. They all run 'hot'. They are all, therefore, falsified and their results should be...

    Help me build a busy Board for toddler

    Switches - come in many shapes and forms, toggle, paddle, rotary, push button, latching, momentary etc. Search eBay - find a Chinese supplier (single source) and order a wide selection. LEDs in all colours including slow-changing RGB (multi-colour). Ebay again, fixed colours, different shapes...

    Help me build a busy Board for toddler

    Most of such devices are simple switches connected to lights or motors. The variety of switch types and lighting types creates 'interest' for kids. You can make one as simple or as complicated as your skills allow. The physical construction is likely to be more challenging than the electrical...

    Help how to build a dc voltage interrupter to control power on and off time. PWN not sutable.

    As much as I admire the versatility of such devices the post is 'gobble-de-gook' to me and, I'm sure, the OP too. The KISS principle is important here. Power switching is best achieved using MOSFETs rather than PNP/NPN (although that still works) as the losses, therefore component dissipation...

    Another example of the lunacy and the morons that believe it: London recorded 30dgC yesterday - a supposed near-record for September - and there's the likelihood it will reach 32degC today/tomorrow. BBC headline News....... What they DON'T tell you is that these temperatures are measured at...

    That has been debunked so many times that I've lost count and anyone that (a) quotes it or (b) believes it - those that do are fully paid up members of the clueless, head-in-the-sand club. Congratulations. You've just exposed your own bias.

    Let's not bother. If you don't know that Google is seriously compromised I don't know how to break it to you. Show me ONE peer reviewed paper that proves, without doubt, that mankind's CO2 emissions are the cause of global warming. No one, not one single person has ever done this. Not. One...

    That function is all part of the operating software. It should be in the operations manual. You don't state make/model so we have zero clue as to what to tell you.

    in the 'mental' department, maybe. The very idea that we are threatened by the weather is utterly ridiculous and there's zero evidence to point a finger at mankind as the source of climate change. The biggest threat, by far, is from the measures being put in place to try to mitigate a NATURAL...

    Opinion about selling value of old turntable and broadcast receiver.

    R-1000 worth around 500 dollars (starting price) depending on condition and what accessories it comes with (you don't state). Antique stuff varies far more widely due to demand (or lack of). Again, condition matters a lot. If you have any particular price in mind then it's wise to be...

    Whatever respect I had for SH went out the window the moment he was conscripted to the global warming hysteria group.

    A lot of problems associated with this form of wiring is that the heating control isn't just a simple switch affair - it's often controlled by a CAN Bus signal via a module locate in the seat itself. As a result you can't just apply a 'voltage' to the SW line and expect the heaters to work...

    1. Yes they do - in star mode they have a neutral connection. Taking a connection from across any phase and neutral will deliver 240V - suitable for any transformer conversion to AC-DC. 2 and 3. Use a CT on each phase to measure current. No one CT is better than an other - you chose the...

    What is the optimal design for loop antenna made of copper stiff wire to transmit at 81.39–90.00 kHz?

    As if charging EV's isn't difficult enough - introduce yet another step of efficiency loss in power transfer....... yeah, that'll help the grid.

    Radiogram record player very faint sound

    Quite possibly an issue with dirty switch contacts when changing modes. Other than that, there might be a break in the audio path that requires further inspection. can you post pictures of the chassis/wiring?
