Multiple mode Environmental Sensor Deck with MKR1000

Many fun environmental sensors need a hardware interrupt. With the MKR1000, you no longer need to choose! You get I2C, analog ins too! Story I love watching the weather, and I wanted to try to capture and graph it. Home weather stations let me see the details for "now", and sometimes tallies for the past hour, or day. I wanted to do more, and use an Arduino for the job. Everyone starts with Temperature and ...

How to Select a Resistor

When I was working on the next version of Common Parts Library, I realized that it would be helpful to explain why you might pick one type of passive component over another. We started off by writing “How to Select a Capacitor” last month, and are following it up with a close look at resistors this month. In this blog, we will explain all the different types of resistors, their merits and demerits, and popu ...

Review & Teardown of a cheap GPS Jammer

Generally, “jammers” — which are also commonly called signal blockers, GPS jammers, cell phone jammers, wifi jammers, etc. are radio frequency transmitters that are designed to block, jam, or otherwise interfere with radio communications. A jammer can block radio communications on devices that operates on a given radio frequencies within its range (i.e., within a certain distance of the jammer) by emitting ...

Teardown: 12V AC adapters

In the name of science, I introduced three of the worst 12V adapters (from My kingdom for a 12V adapter) to my bandsaw. What I found may shock you. Note: All pictures can be zoomed or opened at full size in their own tab. First on the chopping block, the “EH1205”. Wait! What’s this? The original AC connector is mounted to the PCB. Yes, this has been repackaged! I think we can assume the approvals on the lab ...

HID Attack Over WiFi Using Arduino MKR1000

Arduino MKR1000 as a HID, for performing HID penetration testing over WiFi networks. Story Today I have an Arduino MKR1000 which is a board with built-in wifi chipset specially designed for IOT projects. Recently I came to know that, this little board can act as a Human Interface Device such as a keyboard or a mouse. So I thought of using it for some HID attacks over WiFi. In this video, I will show you a s ...

Basic Switching Voltage Regulator Tutorial

A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed properly. Of course, this detail about design is important. They are not as simple as a linear regulator, which is basically an ...
