I’m continuing working with Juan Brito and Danny Macancela from the blog Desafio Ecuador, developing new boards to bring near the technology and programming languages. Our last work is a board to use with the Raspberry Pi and focused to learn Python. The board has the basic elements to start with this language. Also, with the develop of the PCB we remove the wiring, avoiding troubles with connections, inversion polarity…So with this board you only focused in the software develop, because the hardware side will work!
Node-RED is a visual programming interface for the Internet of things. It doesn’t require coding experience, making it easy to connect your physical things to the cloud.
Node-RED is based on Node.js. The Node-RED application runs as a web server, and you customize and manipulate functional “flows” from any computer’s browser, local or remote. The server application can run on an inexpensive device like the Raspberry Pi.

SAN FRANCISCO and MINNEAPOLIS, January 26, 2015 — Punch Through Design, a hardware and software development firm that brings Bluetooth Low Energy hacking to the masses, has released the Windows Bean Loader, the first-ever wireless Arduino programming app for Windows users. Using the loader app, Windows-based developers and hobbyists can easily upload code to their LightBlue Bean and experience the power of Bluetooth Low Energy, without cables or a physical connection to the LightBlue Bean.
“The LightBlue Bean represents a new method of wirelessly interacting with prototypes and projects; says Colin Karpfinger, founder and CEO, Punch Through Design. Previously, only Mac OS X and iOS users could program their Beans, and now we are extending that functionality to Windows users.
The full-featured app, available from the Windows Store, fills a void for Windows-based developers and DIYers looking to create smartphone-controlled devices.

For a project of mine, I need to flash several hundred of ATMegas.
I use a special programming connector, which sits on the SMD chip and connects directly to the ISP and power pins on the chip.
My first attempt to ease the flashing process was to mount the programming connector to a lever with some additional weight on it. That way, once the connector was in place, I didn’t need to hold down the connector manually during the flashing process.
The PCBs come in panels of 40 (10 x 4 PCBs per panel) with milled slots in between each PCB. So to make the positioning of the PCBs under the connector a little easier (and more repeatable), I put two metal pins (with the same diameter as the milled slots) on the base of the lever.

I remember that once in the beginning I said that I don’t want to buy a programmer/debugger hardware for learning a new MCU like the STM32 and also STM32s already come with built-in bootloader to facilitate programming via USART just like Arduino. Still the second is true. Well what about the first? To my own surprise I actually acquired a number of STM32-related stuffs since the time I started playing and exploring them. I actually bought both ST-Link 1 and 2 programmer-debuggers and several STM32 boards from Waveshare Electronics (http://www.wvshare.com). I believe learning new stuffs is more valuable than anything else.

Chris Holden of NerdClub shares his tips on how he successfully program an ATMega128:
Finally got an ATMega128 chip coded and programmed successfully. The great news is it doesn’t require Arduino. The even better news is, we can use Oshonsoft to write the code! Yay.

There are a lot of little details you need to think about when taking a project from PoC (proof-of-concept) to production. Most projects today have some form of onboard microprocessor and require you to flash your custom bootloader and/or program code onto it at some point. There are many ways this can be accomplished but the most common method is using an ICP (in-circuit programmer) connected to a 6-pin ICP header somewhere on the PCB. […]
Tag-Connect! I can’t remember exactly how I found out about this neat little connector, but I’ve been using it for a while and it’s actually very useful in a production environment. They provide the footprint for many of the popular PCB design programs so placing it is very straight forward. Pretty much just swap out the traditional header for the new tiny Tag-Connect version and you’re pretty much done.
