There are already a lot of low-cost, small-sized developing cards that are as well as the development of the educational use of embedded projects. Let’s start with Arduino, Raspberry Pi, ESP8266 NodeMCU, BBC Micro:bit, .. and many other Dev Boards. But it seems that world needs another new educational development board: CodeBug. CodeBug is designed →
Function generator in an important tool in electronics laboratory. It allows to generate different types of electrical waveforms over a wide range of frequencies. Traditionally function generators have been built using analogue electronics. There have been special ICs that have been widely used for this: Exar XR2206 and the Intersil ICL8038integrated circuits can generate sine, →
New version of famous component tester I tested some time ago has arrived. M12864 Graphical RLC/ESR Transistor Tester With AVR-ISP Socket MOS/PNP/NPN M328 is an an updated version of famous M168 component tester. This new model can test all the same components as the earlier version, plus it can do for example in-circuit capacitor ESR →
Here are two interesting looking ESP8266 projects for controlling mains power: MPDMv3 – WIFI Mains Power Dimmer / Switch – Web Interface Arduino IDE – WIFI MAINS Power Switch – ESP8266 MPSMv2 P3 – WIFI Mains Power Dimmer / Switch with CBDBv2 →
Just like the garage computer explosion of the 70’s through the 80’s, which brought us such things as Apple, pong, Bill Gate’s hair, and the proliferation of personal computers, the maker movement is the new garage hardware explosion. Today, 135 million adults in the United States alone are involved in the maker movement. Enthusiasts who →
I have already mentioned that there are several visual programming tools for programming Arduino at my Visual programming for Arduino posting. Now I just read about new ArduBLock tool. ArduBlock is a programming environment designed to make “physical computing with Arduino as easy as drag-and-drop.” Ardublock is marketed as a very convenient way to get people →
When building IoT (Internet of Things) applications, the cloud part where all information from sensors is important. There are many cloud services that can collect IoT data, but the fundamental issue here is that the Internet of Things does not have a standard set of open APIs for consumers. Well, there’s ThingSpeak, but it’s not →
I just saw this interesting article: This Little 3-D Printed Robot Cracks Combination Locks in 30 Seconds article tells that a well-known hacker Samy Kamkar published on his website the blueprint and software code for a 3-D-printable Arduino-based lock-opening robot he calls the “Combo Breaker.” Attach it to any of millions of Master Lock combination →
Since Facebook’s Carlos Bueno wrote the canonical article about the full stack in 2010, there has been no shortage of posts trying to define it. For a time, Facebook allegedly only hired “full-stack developers.” That probably wasn’t quite true, even if they thought it was. Is it reasonable to expect mere mortals to have mastery over →
The ESP8266 is the answer to “I want something with Wifi.” It’s basically the answer to everything IoT to so many engineering problems that have plagued the hobbyist and commercial world alike. The chip is a processor (80MHz Tensilica) with integrated RAM, some ROM, and a WiFi radio. It’s CHEAP, like $4/ea cheap! Or $5 →
