The Basic Arduino Keyer is a great project but was purposely designed to have no frills. This week we will be adding an adjustment for speed and a LCD. For speed adjustment, there is 2 buttons. One is for words per minute up and the other is words per minute down. As you change the […]

Even if you wouldn’t describe yourself as a history buff, you’re likely familiar with the Enigma machine from World War II. This early electromechanical encryption device was used extensively by Nazi Germany to confound Allied attempts to eavesdrop on their communications, and the incredible effort put in by cryptologists such as Alan Turing to crack the coded messages it created before the end of the War has been the inspiration for several books and movies. But did you know that there were actually several offshoots of the “standard” Enigma? For their entry into the 2019 Hackaday Prize, [Arduino Enigma] is looking to shine a little light on one of these unusual variants, the Enigma Z30. This “Baby Enigma” was intended for situations where only numerical data needed to be encoded. Looking a bit like a mechanical calculator, it dropped the German QWERTZ keyboard, and instead had ten buttons and ten lights numbered 0 through 9. If all you needed to do was send off numerical codes, the Z30 was a (relatively) small and lightweight alternative for the full Enigma machine. Creating an open source hardware simulator of the Z30 posses a rather unique challenge. While you can’t exactly order the standard Enigma from Digi-Key, there are at least enough surviving examples that they’ve been thoroughly documented. But nobody even knew the Z30 existed until 2004, and even then, it wasn’t until 2015 that a surviving unit was actually discovered in Stockholm. Of course, [Arduino Enigma] does have some experience with such matters. By modifying the work that was already done for full-scale Enigma simulation on the Arduino, it only took a few hours to design a custom PCB to hold an Arduino Nano, ten buttons with matching LEDs, and of course the hardware necessary for the iconic rotors along the top. The Z30 simulator looks like it will make a fantastic desk toy and a great way to help visualize how the full-scale Enigma machine worked. With parts for the first prototypes already on order, it shouldn’t be too long before we get our first good look at this very unique historical recreation. [do_widget id=text-14]

In the Earth’s atmosphere, a drone can adjust its heading by varying the speed of the propellers, and thus the thrust output of each. If you wanted to land something on a lunar surface, or maneuver a spaceship, the lack of atmosphere means a different technique must be used. While not going to space (yet), […]

If This Then That, also known as IFTTT  is a free web-based service to create chains of simple conditional statements, called applets. An applet is triggered by changes that occur within other web services such as Gmail, Facebook, Telegram, Instagram, or Pinterest. For example, an applet may send an e-mail message if the user tweets using a hashtag, or copy a photo on Facebook to a user’s archive […]

If you get this error than not to worry. We are going to solve this. First why this error occur : because of arduino has leak of library. So we are going to download and extract that library to – C:\Program Files (x86)\Arduino\libraries  (YOUR PATH MAY BE DIFFERENT).

Recently, I was revisiting my electronics components and found my old Arduino Pro Micro clone, which has a similar board with Arduino Leonardo as both boards are based on Atmel Mega32u4 microcontroller. The microcontroller is “featuring a built-in USB which makes the Micro recognisable as a mouse or keyboard.” I wanted to check if the […]

With some help, I made this patch that analyses the live input into three different variables; brightness, volume, and pitch. It detects the spikes in the recording and stores its value. However, these three variables are not enough to distinguish the different beats. I went to a tech lab to ask for more insights. I […]

I always was a big fan of music and instruments. Particularly I was fascinated by people who are able to create music and rhythm patterns using nothing else but their own bodies. Beatboxing is an art form when a performer mimics drum based sounds using their vocals, mouth, and lips. Usually, beatbox has patterns that […]
