    Voltage Drop Issue with Bluetooth Audio Module Using 3.7V Li-Ion Battery Message

    We don’t know the speakers, amp or any flashing lights you have on a poor 3.7v battery!! Give all the information.

    What N-Mosfet to control a small DC motor

    Your posts are relevant for coding platforms. This forum is for electronics. However, there are some very decent coders/programmers on here too. If you took the time to post your code, you should have noticed a code box!. Dang, these people that slag off a site because’they’ can’t use it:)

    Voltage Drop Issue with Bluetooth Audio Module Using 3.7V Li-Ion Battery Message

    Well, I’m sure that you know this is impossible. Battery voltage drops therefore electronic items no longer work!.. A constant voltage is only possible from a reliable mains voltage source or of course a battery for a limited amount of time. A boost converter will drop out quicker if supply is...

    What N-Mosfet to control a small DC motor

    Dana, I’ve learned so much from your posts. I never touched a micro before it came apparently easily. Still not easy but easier!.

    American kitchen door chimes, 1930s-1960s

    My sisters house still has the box of bells with room names on it in the basement flat. It was the servants quarters. They were pulley and crank until I removed it all and used the void for cat5 and new services throughout. I’m going there today, I’ll see if I can get a photo. Martin

    Makita DMR110N Repair - Now Turns On - No Sound

    Do you have a function generator and scope? I would get the data sheets of the ICs and see if signal is present at the input and also at the output.

    Elite2 digi designer 115v to 230v

    I would expect low ohms on a transformer. Even as low as 0.5. After all, it’s just a coil. Maplin do have some online bits n pieces but nothing to write home about.

    3v step down from 12v

    One other simple tip: Using old baking trays are metal and conductive, always use an insulator material too so not to short the solder side of boards. If you have a cutting board, place it between the baking tray and PCB.

    3v step down from 12v

    Please provide more information. What is getting hot?. As already stated, have you got a buck converter?. Step down. If things are getting hot, you’ve probably exceeded the current limit of your device. Please explain your issue and give the information on the device you are using and the...

    I want to know all of the maths concerning this scissor mechanism!

    Woo Woo land exists for a reason. Physics as we know it in 2024 hasn’t changed. There is a weird chap on YouTube called Robert Murray Smith that claims to have reinvented the wheel!. Reality begs to differ. I can get 1000v from 12v but it’s useless!. You can get more voltage from a static...

    16bit to 8bit to save data in eeprom and read it as a 16 bit value again

    You are a wealth of knowledge Harald.

    16bit to 8bit to save data in eeprom and read it as a 16 bit value again

    I’m not clued up on this at all so maybe nonsense, but I remember cloning hard drives with the same situation. I could clone a 250Gb onto a 1Tb and only ‘see’ 250Gb. The rest of the available storage space was unavailable.So you might have to change the settings again. Or try different software?.

    Ultrasonic cleaner

    10mm socket gets those dentures tight! 40 kHz is perfect for engine and carb parts. I use one at work for exactly that.

    Ultrasonic cleaner

    Well, fine and sanitary cleaning is recommended for 45 kHz . A standard 40kHz machine should suffice.

    Ultrasonic cleaner

    What ultrasonic cleaner is it? Cavitation can be from 25 kHz to 130 kHz. Every day ultrasonic cleaners are 35/37 kHz. Mine is an Allendale ultrasonic cleaner. Excellent quality tool @ 40 kHz.
