  • Perfboard Circuit for ESP8266 Programmer

    Sean_Miller
    This is the next deep dive video for an up-and-coming Project14 build.  This follows my last blog post where we designed a circuit for a programmer board for the ESP8266.  This programmer coupled to the Arduino IDE makes programming the ESP...

  • SCITS Timer Project #4 - Digital Input Testing

    three-phase
    As part of the design process, I need to find out how the digital inputs of the SCITS available to me function along with the inputs to the counter / timer unit that I will utilise to calibrate the timer I am building. The counter / timer unit i...

  • Keysight U1461A Insulation Multimeter Test Fault Update #1

    three-phase
    A while back I showed an issue I had on my Keysight  U1461AU1461A Insulation Multimeter when carrying out insulation testing on large generator rotors that led to invalid results being displayed on the meter when in fact the winding insulation w...

  • Transistors: The Ho Serial Astable

    jc2048
    Back when I first became interested in electronics, a simple way to make an oscillator was a circuit called an astablemultivibrator. These got used a lot - the electronics magazines that I used to buy as a teenager were full of them. Thisis the form ...

  • How many DE0 boards can I break?

    pinkhairedcat
    So it's been a while since I had time to post anything. Classes keep me pretty busy. since I last posted I wrote a program to do Ohm's law calculations, mostly just for fun, drew the circuit for a 4bit adder and then wired a 4bit adder (with some hel...

  • SCITS Timer Project #3 - Timer Concept

    three-phase
    This blog will look at the initial concept I have for building the timer. When built, this timer will form part of the initial tests I do when setting up for protection relay tests to show that the apparatus is performing correctly. Testing the ...

  • SCITS Timing Project #2 - A SCITS at Work

    three-phase
    Before getting into the project build, I thought it would be useful to show how a secondary injection test set (SCITS) is put to use, to give a better idea of the timing requirements. The SCITS utilised is a single phase Megger SMRT1 unit and th...

  • Uh-oh broken my voltage probe

    three-phase
    This wasn't supposed happen - there I was happily sorting through my tools ready for a job tomorrow and my trusty old Kewtech KEW1700 voltage probe decided to exit the tool bag in two parts. This is the test apparatus that I use for the test...

  • Long term component shortages create an unexpected threat

    RogerUKEA
    Many original component manufacturers (OCMs) reported their highest sales growth figures for seven years in the first two quarters of 2017 and, six months later, this has now developed into significant increases in lead times and pricing that haven’t...

  • Booards and Boojums: Lattice XP2 Brevia2 Board: Part 2: Count Those LEDs!

    jc2048
    It seems 2018 is going to be the 'Year of the FPGA' here on element14 ('Forward Heroic Engineers of the World to a Flip-Flop Rich Future'), so I thought I'd join in, buy a small development board and do a simple project or two. The board I'm working ...

  • Hosting options vs price

    gam3t3ch
    Searching for a host now, seems my pi I keep messing up my permissions left right and center causing me to well loose a day redoing it all so what I want to know does anyone have hosting with a company and  why did you choose them and is it a go...

  • Learning Things

    pinkhairedcat
    Been busy. Spent 13 hours on campus yesterday and spent 6 hours today. Feels almost nonstop though since once I finished yesterday I went to bed, woke up and went to class. Yesterday didn't provide much info on the FPGA like I had hoped but I did get...

  • Got my first FPGA

    cybermah
    Browsing through element14's community post a few months back I notice some articles about FPGA's.  At first I dismissed them mainly because I didn't know what they were. And I didn't think I would ever use one or what one was.&n...

  • 为树莓派3b部署手写数字识别卷积神经网络

    dremofly
    题目：为树莓派3b部署手写数字识别卷积神经网络介绍：在2012年的ImageNet竞赛上，基于卷积神经网络的AlexNet横空出世，以绝对优势拿下冠军。从那以后，人们开始认识到神经网络在图像识别领域具有巨大的潜力。其实早在1986年时，LeCun就发表了Lenet，但是由于计算能力等问题，神经网络一直没有流行起来。直到2012年，Hinton和他的弟子Alex创新地使用两块Gtx 580进行神经网络的计算，才使得计算能力的问题在一定程度上得到了解决。同样是因为计算能力的问题，现在的神经网络训练甚...

  • small victories

    pinkhairedcat
    Finally got the DE0-CV to connect to the control panel so I can at least see everything works. not totally sure what made it work, kept getting tons of errors. Installing a Quartus II 15.0 seems to have helped (Im still using Quartus Prime 17.1 for p...
