Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them.

Breakfast at DEF CON — The Greatest Illicit Meetup of All
Every year we host Breakfast at DEF CON on the Sunday morning of the largest hacker conference in the United States. I think it’s a brilliant time to have a meetup — almost nobody is out partying on Sunday morning, and coffee and donuts is a perfect way to get your system running again after…

All the Badges of DEF CON 26 (vol 1)
Two or three years back you would see a handful of really interesting unofficial badges at DEF CON. Now, there’s a deluge of clever, beautiful, and well executed badges. Last weekend I tried to see every badge and meet every badge maker. Normally, I would publish one megapost to show off everything I had seen,…
I Can Solder Badge on Tindie
From Bradley Ramsey on the Tindie blog:
Say it Loud and Proud With The I Can Solder Badge
When you take your first steps on the road to becoming a maker, one of the first skills you’ll need to master is soldering. It’s the backbone of just about every electronics project, but it’s not an easy skill to master. Don’t let the fear stop you, soldering opens up a lot of DIY projects for you.
With the I Can Solder Badge, you’ll not only learn the basics, but you’ll also have proof to show the world. This badge project is unique in that it also teaches you about circuits and includes a switch to save the battery power.
Included in the kit is a purple PCB manufactured in the USA by OSH Park, an RGB LED, a resistor, a switch, and a battery holder for the CR2032. Keep in mind that you’ll need to purchase the battery yourself as it cannot be mailed out with the kit due to USPS guidelines.
The Square-Inch Project Rides Again
Want to play a game? Your challenge is to do something incredible with a printed circuit board that measures no more than one inch by one inch. It’s The Return of the One Square Inch Project and it’s going to be amazing! We can’t believe that it’s been three years! The original One Square Inch Project was […]
Car Hacking at DEF CON 26
A great place to get your feet wet with the data-network-wonderland that is modern-day automobiles is the Car Hacking Village at DEF CON. I stopped by on Saturday afternoon to see what it was all about and the place was packed. From Ducati motorcycles to junkyard instrument clusters, and from mobility scooters to autonomous RC […]
Big Power, Little Power, Tiny Power, Zap!
Our Hackaday Prize Challenges are evaluated by a panel of judges who examine every entry to see how they fare against judging criteria. With prize money at stake, it makes sense we want to make sure it is done right. But we also have our Hackaday Prize achievements, with less at stake leading to a more […]
Review: SMD Tweezer Meter or Tweezer Probes For Your Multimeter?
It’s remarkable how tiny electronics have become. Heaven knows what an old-timer whose experience started with tubes must think, to go from solder tags to SMD in a lifetime is some journey. Even the generation that started with discrete transistors has lived through an incredible shift. But it’s true, SMD components are tiny, and that…

Homebrew Pancreas Gets 30 Minutes of Fame
It is pretty unusual to be reading Bloomberg Businessweek and see an article with the main picture featuring a purple PCB (the picture above, in fact). But that’s just what we saw this morning. The story is about an open source modification to an insulin pump known as the RileyLink. This takes advantage of older…
SMD Soldering Challenge Lands At DEF CON
