    stm32 problem with ADC conversion

    Hi Mike. Not sure how big your code is but it would be good if you could post your main code in full, so we can have a look for you. Thanks Adam

    Ardiuno voltages - Beginner

    A lot of circuits designed for 9 volts were so you could run them from PP3 batteries. It probally a historic thing having an input for 9 Volts. Adam

    The curve of the sun?

    I take it as the sin function is used for the intensity of the sun not the length of the day. I might be wrong though. Thanks Adam

    PCB mounted transformer

    Hi Gareth I would keep the two regulators separate. You will most definitely need a heat sink if you are going to use a linear regulator. You can buy switch mode regulators and what you would need is called a buck converter, they can be a bit noisy so a simple LC filter usually sorts this if...

    Distribution of a 28.8mhz clock to 4 circuits

    If most of the circuits use clock buffers then it might be a good idea to use one; don't you think? To gain experience with anything you have to at least try it once. There will be lots of information on the internet regarding clock buffers I am sure of that. Have a look and come back with...

    PCB mounted transformer

    Hello Gareth. Welcome to EP. The transformer is more than likely a custom transformer they had made. The chances of finding another one with the same winding voltages, wattage and pin configuration is going to be difficult. One option is to try and find a schematic of the PCB you have and hope...

    Lifting a platform floor under a chair for a flight or car simulator

    The actuators have the motor built in, you don't need to supply one. 50 - 60 Ibs, no problem just choose one that can lift that and has the required displacement length. Adam

    Resistors, Capacitors, Zener diodes... Why the funny values?

    It might be a bit off topic but is it worth mentioning why we have strange values of voltage references like 1.024 V and 4.096 V etc. Also why zeners have the values they have e.g. 2.4, 3.3, 5.1,7.5 and the importance of the 5.6 Volt zener. Thanks Adam

    Help design a very simple momentary on/off circuit

    I am sure it will work at 6 Volts. Give it a try :) Thanks Adam

    Pedestrian Crossing Light Project

    Just found this simulator it may help you. Looks quite impressive. It's free for a few days and then you go on to the hobbyist version. http://www.docircuits.com/search-circuits/tags/MULTIVIBRATOR Thanks Adam

    Lifting a platform floor under a chair for a flight or car simulator

    Hi Greg, welcome to EP. Have a look at linear displacement actuators. https://www.google.co.uk/search?q=linear+displacement+actuators&num=100&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjZ1Iy9hd7SAhUrJcAKHedYCOEQ_AUICSgC&biw=1600&bih=802#spf=1 Thanks Adam

    Ethernet transformers from Mouser -- awesome service

    In the UK I think it's a 33 GBP order for free shipping. Shipping is 12 GBP I think. Adam

    Newbie looking help with remote 12v linear actuator project

    Hi Shane, welcome to EP. Do the actuators need to be on a travel timer, or do they stop when they reach their limit? Thanks Adam
