    Is Hardware engineering Dead in the UK?

    For Quant jobs, they do hire maths guys but they aren't looking for any maths undergrad mostly top top PhD students studying Bayesian stats and anything stats related. Otherwise they look for any competent person with a STEM degree and a proven track record, run their ass down for 5-10 years...

    Is Hardware engineering Dead in the UK?

    Thank you for the input. I did check prospects, infact I think they have the highest graduate salaries in the UK (Imperial College London, mostly since all go work in the City) and overall I am very happy with the course (electrical and electronic engineering). The hardware scene here is dead...

    Is Hardware engineering Dead in the UK?

    MacIntoshCZ It most certainly isn't free. For UK citizens, its £9250, £30000 for international students and that is excluding living costs which around the university are around £200 a week excluding bills. Nigel Goodwin I had a look. In regards to Europe mostly Germany and France you have to...

    Is Hardware engineering Dead in the UK?

    A couple years ago I undertook an electronics related course in high school, I got interested in electronics and luckily I somehow landed a spot in a top 3 UK engineering university. Now that I am approaching the end of my degree here I am looking at jobs and frankly there are no engineering...

    18650 Li-ion Battery Protection Boards

    In terms of accuracy, it is reasonable, not perfect but workable. The 360s are easier to work with as it has more libraries built for it and drivers etc.

    18650 Li-ion Battery Protection Boards

    Thank you for the response. The servos are continuous servo motors (360 degrees). The input voltage has to be rather accurate. since these don't have any feedback, I am using speed and velocity to determine their position and the input voltage has an effect on the velocity. At 5v they run at max...

    18650 Li-ion Battery Protection Boards

    Thank you for your response Nigel and Pommie. The system: An arduino taking in 5V -> connected to a driver circuit -> connected to 20 servo motors. [ I made a new design and the servo motors will not all be on all at once, max 2 on at the same time but 99% of the time one on at once max.Hence...

    18650 Li-ion Battery Protection Boards

    I am currently using some rechargeable 1860 Li-ion batteries ( similar size to AA batteries) to be able to use a system remotely without needing the mains in remote locations. I read up about these online and it seems they are somewhat unstable and have a lot of leakages and short circuit...

    Getting 5v 5A from the mains.

    Thank you for the assistance, the system is up and running!

    Getting 5v 5A from the mains.

    Good Evening, I am making a device which is going to use: 20 servo motors connected to an Arduino and a microcontroller. The 20 servo motors each need 0.2 amps, the Arduino needs 0.2-0.3 amps and the microcontroller is the same too~(4.6A). I have found things like this...

    Extending Wifi

    Your idea was what many people I know do, The issue is, I will be connecting phones couple laptops there etc. for laptops I have ethernet cables and such so its not a problem, the wires are cheap and I can do the extending easily. For the phone I might give in to the weakness and just get this...

    Extending Wifi

    Hello there! I am not sure If this is the right place to post this, If it is not please let me know. I have recently built an extension in the back of my garden around 20 metres behind my house in the garden. I made a man cave there and I'm trying to extend the wifi to it. Currently, the...
