    cameras

    If there is an Arduino routine for dealing with raw video (CVBS) then look for a car reversing camera or similar. These cameras are about 12mm diameter/long and operate from 12V delivering a reasonable quality signal for 'pennies'. You can get a complete system with video display for 25 or a...

    A shocking thot

    Never seen the point of coloured devices INSIDE a PC case....... who's going to see them? And as for the bells'n'whistle people that think people are impressed by seeing a glowing innards, fluorescent 'wiring', lit-up fan blades and Blackpool Illuminations (Google it) they need to get a life.

    cameras

    The thermal infra red that true 'night vision' (the likes that FLiR manufacture) is beyond the spectrum of the receptors in most ordinarly digital cameras. True, such ordinary cameras are sensitive to IR but in a very limited sense. What makes it more complicated is that the lenses also have...

    Cat collar

    <my bold> To beam enough power at the collar to make it work would be to fry the cat from the inside. Google 'joule thief' and build a battery powered one that will last a 'long time' if you feel you must take this route. Bear in mind that LED's are notoriously narrow beam (a few degrees 'off...

    cameras

    The data is as per the USB standard (whatever the camera is built as i.e. USB 1.0, 2.0, 3.0 etc) - information on the USB standard is pretty widely available as are USB-to-Wifi modules if you want to transmit the signal.

    Repairing cabinet LED lighting with stock power supply

    Replace the lights. They may be 'multi-chip' devices and a defective LED in any one of them will cause the over-current situation resulting in the strobing you see. Cabinets lighting is so cheap these days it's often not worth trying to fix defective versions but get a whole set with matching...

    Cat collar

    Sad fact of life - cat will do what a cat wants to do and no amount of lit-up collars will stop a car killing a cat that runs under it. Speaking as someone who has four cats (and has done for the last 20 years, only one of which was ever killed by a car). Cats are naturally car-cautious but...

    Simple Dual Op Triangle Generator Issues

    Did you build it correctly? Show us the actual build. Did you connect the points marked 0V to actual ground and did you use a split rail power supply?

    Thrustmaster T300 main board issue

    Not sure if we're at cross-purposes here? I'm presuming the pedals plug into the steering wheel which then plugs into the PC? If the socket on the steering wheel (which takes the plug from the pedals) has a damaged connector then no matter what pedals you plug in they won't work. Ergo the...

    Usual USB standard - power, ground, D+ and D- Red, black, white and green cores that match (just about) every USB cable I've ever seen!

    matched impedance question

    It's become an industry and commonly referred to (by engineers who know the truth) as 'Audiophoolery'. I don't feel sorry for either side in that particular scam - a fool is easily parted from his (or her) money if you're a believer in Audiophoolery or... there's one born every minute (if...

    I've had success with camera modules from old laptops - they are invariably USB (4-wires).

    Thrustmaster T300 main board issue

    Clearly the port (on the wheel) you plug the pedals into has an issue - potentially a bent/broken pin.

    Need Help About Word Combine Generator

    Done that - now I know what a 'word generator' is. What 'issues'? What do you mean by 'broken words'?

    Non-Addressable RGB LED strip communication via addressable microcontroller

    Do you want the basic colours (maximum 8) or full spectrum?

    transistor burn in my RTX 3080

    1. No 2. No idea 3. Possibly 4. Find another identical card and try to identify the marking on the top of the burned component. The only other way is to find a schematic of the board (almost impossible) or ask the manufacturers (equally useless). If you can identify the burned device type...

    Where to buy shielded jumper cables?

    Try using ribbon cable with alternate cores connected to ground. Ferrite beads on each data line would also help but I suspect it isn't necessary.

    matched impedance question

    Those are screened cables - I suppose they'll work but not exactly the right thing to use.

    Working on a 3-voice 40106 oscillator. Need help...

    Since the signals are all logic level there should be no difference in actual amplitude between them - other than your own ears ability to hear lower frequencies better than you do the higher frequencies.
