In this video I will be having a closer look at conductive ink pens and find out whether they are useful when it comes to creating electronics circuits. I will test 2 different types by doing an experiment targeting the resistance, current capability and frequency response. At the end we will know for certain in which way such conductive ink pens can be used.

    bet you could make multi layer pcb's with it if you dedicate to it.
    aka laser cutter and or plotter to make stenciles ink the lines solder mask next layer etc etc.
    And or like a screen print….
    i onces tried to etch glass then addes solder past into the etches and then lasered them.
    And yes it kinda worked
    O.o
    ill check that out once i moved….would be awesome if you could layer them up.

    I had used a conductive pen to jump pins on an old AMD Athalon 64 professors. Made it run faster speed. Worked well.

    It is sad that you advertise EasyEDA which, however, is not suitable for the creation of a "professional pcb". This is a tool for children because beginners should not be recommended, Unfortunately I listened to it. Now I know that, for example, Kicad is much better

    You could always use tape over a trace if you needed to cross another trace or to make a second layer clever stuff really

    Hmm… what about a stencil? Using this ink like a solder paste ; also use a non-soaking-surface so paper wouldn't be great at having a stencil with this thing applied on it.

    I've used a pencil to draw circuits. The graphite is conductive. On the original run of Athlon CPUs you could enable overclocking by drawing a line with a pencil on the top of the chip to connect two contacts. I've used a pencil to draw to connect a broken trace on circuit boards.

    I oversee a vape store web directory and we have had a listing from a vape shop in the United States that additionally markets CBD goods. A Calendar month later on, PayPal has written to use to claim that our account has been limited and have requested us to take out PayPal as a payment method from our vape store website directory. We do not offer for sale CBD goods such as CBD oil. We only provide internet marketing solutions to CBD companies. I have visited Holland & Barrett– the UK’s Top Health Retailer and if you take a close look, you will see that they promote a relatively extensive variety of CBD product lines, particularly CBD oil and they also happen to take PayPal as a payment method. It emerges that PayPal is applying contradictory standards to many different companies. Due to this constraint, I can no longer accept PayPal on my CBD-related internet site. This has limited my payment possibilities and currently, I am heavily contingent on Cryptocurrency payments and direct bank transfers. I have consulted a solicitor from a Magic Circle law practice in The city of london and they stated that what PayPal is doing is absolutely not legal and inequitable as it ought to be applying a consistent criterion to all firms. I am still to get in touch with yet another legal representative from a US law practice in The city of london to see what PayPal’s legal position is in the USA. Meanwhile, I would be extremely appreciative if anyone here at targetdomain could offer me with different payment processors/merchants that work with CBD firms.

One other thing I would like to say is the fact that newer laptop operating systems have a tendency to allow more memory to get used, but they additionally demand more memory simply to run. If an individual’s computer can not handle far more memory and also the newest software requires that memory space increase, it is usually the time to shop for a new PC. Thanks
