    Toothache

    I cook with cloves (curries) and have a large jar of them and one lightly crushed between the aching tooth really helps - but so do modern medications and since we keep both tooth gel and various painkillers (ibuprofen being the best) in our EOTW kit I have enough to stave off the pain for...

    Digi pot for pwm board

    The device is controlled over a serial comms bus (I2C) using the SDA and SCL lines (plus the AD0 and AD1 lines) and it would be best to use the likes of an Arduino as there are 'libraries' already written for the device that can control it very simply.

    What does your workshop / workbench look like?

    ....or, as is my case, the way OUT.....

    Current Operated Relay

    I also believe I reiterated that in a later post reply - I 'think' the OP noted the fact but it's just as well it's been brought up again in case it was forgotten.

    Naw... I route PCBs with it......

    What is your troubleshooting sequence?

    Damned right! First question to ask is always "what was the last thing you did with it before it broke?" Then ask if the equipment has ever failed before and how). But the number of times I've been called out and it's been a 'finger-fault' is incredible..... One boat owner insisted his...

    MFOS VCO fault

    Did you connect the ground? It's +12V * GROUND * -12V. Show the board itself - top and bottom please.

    Should I apply pressure occasionally to a burger when I'm cooking it?

    LOL. It's a burger - not fillet mignon......:rolleyes: Make the pattie wide enough to allow for shrinkage, get your mate to stand beside you and mumble "oh yeah..." and another mate (with obligatory beer in hand) to agree with you when you say 'do you think it's time to flip them?'. Job done.

    pls equivalent transistor d2396

    They commonly drop the '2S' designation from such device numbers so you're looking at the 2SD2396 which is an NPN Darlington, TO-220 package, 30W, Vceo=60V and Ic=2A, hfe=1000 and Ft=40MHz. What is the current application for the device you have? If NPN Darlington is correct then you can use...

    What is your troubleshooting sequence?

    Depends entirely on the type of equipment - many faults are quite common these days and cause the experienced engineer to skip a few of the basic tests and jump straight to the 'probable cause'. But the training I was given (and subsequently taught in my latter years) did have proper thought...

    Cheap 3-Axis Mills

    Yup, I agree - total b0ll0x. A CNC can easily move at 10's or 100's mm per second and I've never seen a 3D printer move at anywhere near those speeds anyway! I did watch a Youtube video of a milled PCB that did 0.4mm pitch IC's (it was an adapter board - to standard 0.1" pads) which was...

    Tractor fuel sender not working

    Fuel sender? You mean the fuel METER sender? or the fuel PUMP? The fuel meter not working won't stop the engine getting fuel. A fuel pump problem will.

    Stepper motor control

    You need to search using 'high torque servo' to get the right one.

    Real Solder

    The most prolific lead polluters???? Fishermen. (rod, line etc) Otherwise it's the usual vested-interest groups forcing policies onto taxpayers and making a mint from it.

    Solar charging module for LiFePO4 batteries

    I didn't read that far......:D Yes, I'll keep a project log as the system (remote water system monitoring) could be useful to a lot of places round where I live - many villages have their own ground water supplies (into tanks, filters etc). Because this is a 'community' project I'm hoping to...

    Real Solder

    Most electronic component suppliers stock it. It's not 'illegal' (as some people seem to believe) - it's only manufacturers that have to use lead-free stuff.
