From my very egoistic perspective, the only thing truly missing in the IoT Sensor Badge is a proper iOS app (mind an Android app is available) but, as often is the case, every shortcoming can be seen as a challenge… The IoT Sensor Badge is
Pythonista3 is simply the most fun and easiest/fastest way to develop iPad/iPhone apps/demos (in Python) to complement your IoT demos and projects. Apparently the app has been in the Apple Store for more than three years and the author has
“In 10 Lines of Code: Rapid Development using Cloud Tools for Embedded Control”. It has been another very intense season, so much that I barely had time to make a proper announcement of my new book: “In 10 Lines of Code”, (Lulu, 2016) after…
Looking deeper inside the PIC16F18855 datasheet [link] I found out a couple of interesting new things that deserve your attention: Frankly, the new Constant Current Output control feature is perhaps the most intriguing of the lot. In short,…
Back in August a press release announced the imminent launch of the new PIC16F188xx family [link]. This was bundled with another similar launch for the PIC16F157x family that I have reviewed with a tiny bit more detail in this previous post…
Watching a retro Basic interpreter running on a modern MCU is somewhat poetic to me… Even better if the Basic interpreter is in its turn running on top of a (retro) Virtual Machine as is the case of the TinyBasic implementation of Tom Pittm…
Playing with the Bluetooth Low Energy Click board (BLE2 based on the RN4020) on a Curiosity board is a fun way to get acquainted with this technology. My first humble step was to get the simplest example offered in the RN4020 PICTail (one o…
mruby is a lightweight implementation of the Ruby language designed to be linked and embedded into other applications. It is a branch of the original project initiated by the same author Yukihiro Matsumoto (a.k.a. Matz) and a strong interna…
The idea of driving a VGA display directly from the I/Os of a small 8-bit microcontroller might seem crazy at first, and perhaps because of this, it is certainly entertaining, and possibly useful to some of you. It is actually easier than m…
The Oberon 0 compiler I recently wrote (in Python) after following the online Compiler Construction course [1, 2] included much more than a single pass compiler. In the best tradition of such courses based on the work of N. Wirth, the lexer…
It’s the small things, the smallest boards, that often make my day! This is the MCP2221 breakout board (ADM00559), and it is my new Swiss Army Knife. If you are not familiar already with the MCP product line, these are generally simple conn…
Learning has never been easier! Massive Open Online Courses are a real thing, and while we can debate how high we are at this point on the hype curve, the world is a better place because we do have access to a new powerful set of tools for
