Trying to make [this] work with the Arduino IDE on a Wemos D1 Mini. The additional capacitor got loose, so that there were fluctuations in one row. One row seems to be dead now, after I tried to resolder the QFN chip with my soldering iron. Instead...
With some quite decent tooling and equipment coming from China these days, my curiosity was sparked as I saw a rather affordable kinematic mount. For those not familiar with such lab equipment, this is a holder for lenses, prisms, filters or anything...
Introduction I'm assuming that if you're reading this, you own a Mac. Great hardware (debatable?), smooth software, not Windows, and impeccable build quality, not to mention your unshakable fashion at artist's conferences, among web developers,...
Among the old projects in my junk box was a digital clock I made in the late 70s, using the National Semiconductor MM5371, a one chip clock. Back in the day I used an iron core transformer to supply power. I decided to replace this with a wall wart supply...
Do you have an idea of putting up a blog? Well, the truth about creating blogs is that you will have to select a great platform with a ton of invaluable features to drive success in your blogging. Once your blog is created, the choice of your hosting...
Not a project, but wanted to share something I did the other day. Emma, my trusty Model M keyboard has been ill with a case of rotten membrane contacts since the day I was given her for free. Some conductive ink helped mitigate it, but without a proper...
This article shows you how you can make a simple cooking timer. You can see my circuit working in this video: Step 1: Design the Circuit I designed a simple RC (resistor-capacitor) charging circuit and simulated with PSpice simulation software: The voltage-controlled...
A discussion at the bottom of Donald Papp's article We All Need A Win Sometimes talks about getting through the boring parts of a project. My response is based on what I've found out about motivation. sjm4306 says: I used to find the process of designing...
1. Working principle The working principle of the circuit board is to isolate the conductive layer of the surface copper foil with the board-based insulating material, so that the current flows in various components along the pre-designed route to complete...
It has become indispensable for today's leading-edge software companies to work with an open source audit because of the large portion of components obtained from multiple different entities. Since it involves a lot of license compliance, risk...
Tearing into Sony WH-CH510 headphones These headphones were stolen off a friend who had owned them for many years as he was going to throw them out. Why were they bin worthy? A piece of plastic snapped on one headphone, which I was able to fix with a...
IR Remote Control Circuit Introduction Welcome to another blog. I hope you guys are doing good…. So, it's time to do something interesting. Here in this blog I will guide you how to make an IR controlled remote. Through which you can control your...
Using Flexible Rigid PCBAs to Make Electronics More Reliable Expensive and complex discrete interconnect cables can reduce design reliability, increase design cost and overall design size. In practice, discrete interconnect cables are a disadvantageous...
Printed Circuit Board (PCB) manufacturing is a crucial aspect of the electronics industry, as PCBs are the backbone of most electronic devices. The manufacturing process of PCBs has evolved significantly over the years, with various trends and technologies...
Basement waterproofing is a crucial aspect of maintaining your home that is often neglected. It is a barrier to prevent moisture from entering protecting your home's foundation from potential damage. This is not only a nice thing, but it is an essential...
