    Get your tin foil hats out....

    Zerohedge is reporting on a fall in Intel share price due to a 'flaw' in their latest processor core that can be exploited to gain access to stored passwords...

    Three Tank Control System

    If 20mA sets the valves to fully open and under operating conditions this is not happening then the problem is mechanical/fluid - are the valves orientated correctly (i.e. do they flow better in one direction than the other?). Is there a physical interference?

    How can I test a xlr charging port

    Do you get the same 24.7V on the charger plug when it's NOT plugged into the scooter? The panel LED on the charger could still be lit even if the OUTPUT was missing due to a blown fuse - the LEDs are part of a prior-operating circuit that indicates the status of charge, not the actual output...

    How can I test a xlr charging port

    According to the diagram I have, pin 1 is negative and 2 is positive (not 3). These pin numbers reference the connection on your scooter, not the charger. I expect the wiring to the plug form the charger to match this numbering. If there has been some confusion in the pin numbering and...

    Bitman BM 1384 Chip

    Pretty pointless mining Bitcoin given it costs some $3,500 in electricity to get one - assuming you DO. I'd be looking at the 'lower end' crypto currencies for mining, essentially getting in at their start and relying on future gains in much the same way as Bitcoin exploded. To be getting...

    Yamaha RX -V571 Receiver Repair, my receiver is dead does not power on. There may have been a power

    "there may have been a power..............." what? Whether or not it's worth fixing is your choice - if you don't think so then bin it. We can't begin to guess what the fault is or what needs replacing on the minimal information provided. You should check all the accessible fuses (internally...

    How can I test a xlr charging port

    If there's no output from the charger then the charger is faulty. The charger may have an internal fuse.

    Breadboard Wiring

    In the top picture you have all your connections made in row #42. All five holes are physically joined together - shorted. Your LED leads are therefore SHORTED so the green wire is connected to the resistor, bypassing the LED completely.

    How can I test a xlr charging port

    Do any of the charger lights work? Do they change state if a battery is connected? As far as you are concerned a charger is a charger is a charger - in other words, with the correct plug fitted you could use ANY charger to charge your scooter. In fact, get an 'ordinary' charger for 24V (they...

    How can I test a xlr charging port

    What is the make/model of the scooter? They have all the wiring diagrams available on line (not sure about detailed schematics but something is better than nothing). Can you show the charger itself?

    How can I test a xlr charging port

    You presumably have a multi-stage charger therefore with the batteries disconnected it should default to around 24V.

    Tone for thought..

    The Baxandall tone control circuit is used in practically every electric guitar with tone controls fitted. It's not specifically associated with any guitar 'sound' as such afaik. The 'tone' of any instrument is dependent on many variables, body material, solid/hollow, pickup...

    Repair of Corsair Gaming Audio Series SP2500

    Technically we say 'that's f****d' :D Given it's a switched mode supply there could be any number of faulty parts in it now. The main control device is the component bolted to the heatsink just above the 'dodgy' part. It may have failed open-circuit as, should it have failed 'short' the main...

    Water level sensor

    In which case did you REALLY feel a shock? or was this just a nervous reaction? It takes a few mA of current to make a shock 'feel-able' (around 1mA for AC and 5mA for DC and at the appropriate voltages). Perhaps it was just static? Has it been repeatable? Might be worth checking that the DC...

    Repair of Corsair Gaming Audio Series SP2500

    Repairs are always possible however: may be a problem! Do you have a test meter and are you familiar with its operation? You may be working with potentially lethal voltages on that power supply board so you need to know the risks and how to avoid harm. The simplest thing would be to replace...

    Water level sensor

    What type of 12V adapter? If it is a cheap 'Chinese' version it may just be a capacitive dropper circuit - potentially deadly. Use a linear power pack for this application or, better still, batteries.
