    This link is a TTL to USB converter and it works fine but first please explain what's your product? after knowing the details, I could give you a better response/solution

    On this issue. As a USB manufacturer I want something that can be used to test if my USB is working without altering if and before sending them to the market... So advice me

    Am unable to download such Motorola R2600 service manual (Or General Dynamics R2600) supposedly available as .rar at a few places on the web, tried with different compfusers and all choke at every try.  :(   -I do have the operator's manual-

    Please, does anyone have it or has the skills to download it into a CD in .pdf ?  I will cover the cost.
    Or, upload it to the cloud wherever I can download without .rar complications ?

    check this one here and maybe it can help you

  3. In my fridge I have a fluorescent tube that helps in the lighting of the fridge. I have problem with the kind of the operations am getting from the lighting system. I have checked all the part and i have realized that they are working well except for the choke which has a problem. I even dont know how i test the functionality of the choke although from observation it has some black smoke. Help me out to see the solution.

  4. hello everybody. Am a USB manufacturer and I have had many complains from the end users of my USB product where by after sales I have  gotten several information that the USB is not working, I really want to know how i can over come such challenges as for now my company reputation might go down. I want to know how i can test the end product to ensure its functionality without injecting into the phones. I have come across this type of tester ATtiny85 USB Tester - Share Project - PCBWay and am not sure if it is the best. Could any of you have adifferent idea about what am thinking of doing?

  5. Hey!

    I think we have so many open source software that can help you learn about circuits design. The best thing is first to get some relevant knowledge on simple electronic components and their functions eg resistors,  capacitors,  diodes,  transistors,  inductors and transformers. If you get information about this you will be almost there and you can start designing your first simple circuit.
