    Good decision - high voltages, high currents and RF energy aren't items for the uninitiated to mess with. Although I think you'll be lucky to find someone that can fix it to component level given the lack of technical data available. Without schematics it means a lot of 'time' to understand...

    15R Lamp Ballast. Worth trying to repair?

    .....o_O if they were an 'easy' fix you wouldn't be asking! A schematic would obviously make it an 'easier' fix but there's not a long to go wrong - check the switching components (MOSFET's?) and the switching controller. If the switching devices are all OK then replace the controller chip...

    RGB Laser Power Board Issue

    None at all - just ensure the PSU can deliver the required current AND have some overhead (say 50%).

    A few questions on small dual battery solar

    A standard lead-acid battery requires 14.4V to charge, shows 13.8V off charge and can drop to around 10.8V before requiring recharge. Systems that operate from "12V" should be designed to work from 10 to 14V without modification thus using the available supply voltages to their full extent. A...

    Power cuts and my solar power?

    I only ever think of solar systems as those that are fully independent and non-reliant on subsidies - anyone can make/run a system that 'someone else' is paying for........ a 'political' stance for sure but its also a principled one. Such solar systems will always depend on location and use...

    Industrial MIPI camera for Raspberry Pi - Questionnaire

    I didn't know that - thanks for sharing.... However - your questions aren't really appropriate as the choice will be user-dependent therefore making a SINGLE type of system wouldn't be practical i.e. some might want colour, some would be ok with mono. So why don't you design the system to...

    How to measure DC precision Volt+Amp using microcontroller?

    1. Yes, your diagram is awful! 2. I can't see any parts of your system drawing more than 5A from any source - your use of a computer PSU is overkill. 3. The INA**** type current monitoring range of devices will work for all the measurements you need. 4. The system could be powered from a...

    Treadmill control board SIP 20 Pin part number required.

    Your first picture intimates that there ARE some markings on the face of the device: If you can't show or tell us what these markings are then you won't ever find a replacement - assuming that the SIP is the actual fault of course.....

    round slotted nut tool ?

    A device that looks like the spanner used to tighten cutting disks on to an angle grinder seems appropriate. You could fashion one from a small piece of GRP PCB material and use a couple of small bolts as the 'pins' that protrude: these are actually known as 'straight pin spanners' - filing...

    entrepreneurs and companies that work in the field of electrical engineering

    I would have thought that even a freshman would know how to Google the criteria to resolve that lack of information. Even good old 'Yellow Pages' would work if you lived somewhere that the internet didn't work - but since you messaged here..........

    Power cuts and my solar power?

    I live in a forest on the banks of a Scottish loch (Loch Awe). Private water, private sewage and (until recently) suffered many blackouts due to power lines constantly being brought down in high winds. The forestry commission eventually cleared the areas where the lines ran but it hasn't...

    What do you reckon the most produced component is?

    Transistor. There are 'billions' in each modern processor.

    Rangemaster Induction Hob

    Just discovered that code 6 may refer to 'internal temperature too high for more than 3 seconds'. There are many things that can cause thermal issues - simple dirt/grease for instance - but equally it could relate to a defective component(s). May even be related tot he position of the...

    Rangemaster Induction Hob

    Got the actual make/model of the unit? Got any pictures of the insides/electronics? Seems like the issue could be component-level (unless you know what error code 6 actually means?) so this could be either a board replacement job (do you know if spares are available?) or component replacement...

    Panasonic DMR-E75V VCR/DVD Recorder combo player - Lost power

    Look for cracks around the tracks where the power input socket is located - strain on the lead/pcb often breaks the continuity.

    How to measure DC precision Volt+Amp using microcontroller?

    You're planning to run a 'Platimum PC power supply' - how much power will THAT consume? A micro-AT motherboard runs at under 50W, potentially much less at idle. If energy is a genuine concern you'd be looking to run most items at standby for most of their time so your intended monitoring...

    Power cuts and my solar power?

    I disagree. It depends entirely on HOW you live your life and what you consider important. I use a 900W (realistically it's only 700W maximum), good quality inverter-generator (IG) that provides us with lights (15W of LED), TV (80-100W on modern set), internet (2W) and laptop/tablet (30-70W)...

    Accuracy Component Tester.

    Nope, the screen (LCD) display is that of one of those cheapo Chinese 'multi-tester' devices.
