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

jc2048 — Mon, 14 Mar 2022 13:23:00 GMT

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...(read more)

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...(read more)

Powering Up and Debugging PCB Prototypes

fmilburn — Mon, 14 Mar 2022 03:09:00 GMT

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...(read more)

EyeBall Thingy

dubbie — Sat, 12 Mar 2022 12:57:00 GMT

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 ...(read more)

Prototyping Techniques - In Search of the Easy Way

dougw — Mon, 07 Mar 2022 04:58:00 GMT

IntroThis blog outlines how I have historically done electronic prototyping, but I will mention some other methods for completeness. Over the years my prototyping preferences have shifted dramatically in search of more efficient methods, however many...(read more)

DIY SMD Breakout Board and SMD Soldering Techniques

rsjawale24 — Sat, 26 Feb 2022 17:09:00 GMT

DIY SMD Breakout Board and Soldering Techniques SMD soldering can be quite difficult for beginners. Although there are numerous videos on YouTube showing SMD soldering techniques, it takes time and practice to master the art of SMD soldering especial...(read more)

Temperature gradient PCB

neuromodulator — Mon, 21 Feb 2022 05:44:00 GMT

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...(read more)

Proto Board Performance Enhancing Wingdings

kmikemoo — Mon, 21 Feb 2022 00:58:00 GMT

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"...(read more)

Building an IOT power supply - Part2

dimiterk — Wed, 16 Feb 2022 01:13:00 GMT

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...(read more)

Building an IOT power supply - Part1

dimiterk — Sun, 06 Feb 2022 22:39:00 GMT

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...(read more)

Prototyping experiences

strb — Tue, 01 Feb 2022 19:57:00 GMT

Hi all! There is no such "superior prototype technique" for circuits. Every project has its unique caracteristics and that imply different prototyping technniques. Down below I will present my experiences, what techniques I use the most, what I don't...(read more)

Circuit Prototyping

rsc — Mon, 24 Jan 2022 03:20:00 GMT

I keep a bunch of small breadboards around for prototyping. There are three types of circuit prototyping methods I tend to use. The first is just a simple breadboard. https://uk.farnell.com/global-specialties/gs-400/breadboard-abs-35-56mm-x-83-82mm/d...(read more)
