  • P14 Prototyping Techniques: Attempting to Measure Op Amp Open-Loop DC Gain

    jc2048
    As an experimenting blog, this one was a bit of a failure, but I can at least use it to show the prototyping technique that I'm most fond of. As a guide, I'm using an Analog Devices article [1]. This suggests the use of a second op amp to servo the f...

  • Old times

    "When I was youngI never needed fotoresistAnd making circuit boards was just for funThose days are gone..." Yes, it sounds like the beginning of an old famous song by Eric Carmen and that's what I'd like to talk about in this blog. I'm Carlo Russo an...

  • Powering Up and Debugging PCB Prototypes

    fmilburn
    I recently started a discussion in the "Ask an Expert" forum that described the process I used to start up an untested circuit and asked what tips other element14 members have on the subject.  There were many good suggestions in t...

    My prototyping techniques are fairly limited and pretty standard: using stripboard or protoboard. One day I hope to graduate to PCBs but so far I haven't gotten around to it as learning a PCB package doesn't seem like fun. And, as they say, when the ...

  • Prototyping Techniques - In Search of the Easy Way

    Introduction Ion channels are ion gates that control the flow of ions through the cell membrane and in this way raise or lower the cell voltage. When the voltage of a neuron reaches a threshold an action potential (a voltage wave) that travels t...

  • Proto Board Performance Enhancing Wingdings

    kmikemoo
    Many of my projects start out a little half baked so breadboarding them is a must.  One of the things that has bothered me in the past is when I need a common buss and I run out of holes.  Sure I can add a jumper, but that "costs"...

  • Building an IOT power supply - Part2

    3. Testing This post  continues from  Part I by showing how the power supply was tested. The only issues encountered during assembly was an incorrect cap on the external loop. C1 from 1uF to 100nF. First a preliminary simulation using TI w...

  • Building an IOT power supply - Part1

    dimiterk
    Recently I implemented a custom power supply for an IOT system. The requirement needed was to provide at least 2.5A to fully power on a RPI SBC for a control and monitor solution as well as a 24V output for powering a stepper motor. 1. Design T...

  • Prototyping experiences
