For this reason, we have put together some top tips for PCB design layout. Keep reading if you would like to find out more about this. Leave Enough Space One of the most important design tips for PCB layout is that you need to make sure that you are leaving enough space between the components.

Print Out Your Layout Struggling to find out if your components sizes match? Our next tip is to print out your layout and compare the printed version to your actual components. Datasheets can sometimes come with errors, so it doesn’t hurt to do...

I did a blog post many years ago reminding folks that The Internet is not a Black Box . Virtually nothing is hidden from you. The same is true for your computer, whether it runs Linux, Mac, or Windows. Here's something that happened today at lunch. I was testing a local DNS Server (more on this on Thursday) and I started it up...and it didn't work. In order to test a DNS server on Windows, you can go to the command line and run "nslookup" then use the command "server 1.1.1.1" where 1.1.1.1 is the DNS server you'd like to try out. Go ahead and try it now. Run cmd.exe or powershell.exe and then run "nslookup" and then type any domain name. You should get an IP address. Given that I was trying to run a DNS Server on localhost:53 (Port 53 is where DNS usually hangs out, just like Port 80 is where Web Servers (HTTP) hang out and 443 is where Secured Web Servers (HTTPS) usually are) I should be able to do this. I'm trying to send DNS reques...

I recently stumbled upon https://accessibilityinsights.io . There's both a Chrome/ Edge extension and a Windows app, both designed to make it easier to find and fix accessibility issues in your websites and apps. The GitHub for the Accessibility Insights extension for the web is at https://github.com/Microsoft/accessibility-insights-web and they have three trains you can get on: Canary (released continuously) Insider (on feature completion) Production (after validation in Insider) It builds on top of the Deque Axe core engine with a really fresh UI. The "FastPass" found these issues with my podcast site in seconds - which kind of makes me feel bad, but at least I know what's wrong! However, the most impressive visualization in my opinion was the Tab Stop test! See below how it draws clear numbered line segments as you Tab from element. This is a brilliant way to understand exactly how someone without a mouse would move through your site. I can easily s...
