LED Snowflakes by Mike Harrison

at 10:26 pm. Filed under DIY Hacks, Electronic Hacks

 

Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.

How to Build IOT Devices – Talk by Joe Menard

at 11:33 pm. Filed under DIY Hacks

 

Joe Menard had many needs for IOT devices in his life, he is an electrical engineer but needed fill in lots of programming knowledge to get his ideas to come to life. He started at a very low level even building a switch mode power supply, with 170 volts on board trace spacing was something that was very important. For the enclosures he didn’t simply buy something and stuff his circuit into it, he custom designed it and 3D printed it.

Arduino State Machine

Statechart-Platine-Arduino

 

If you are looking for new ways of getting your Arduino gear to become productive why not try programming it as a state machine.

Via: Electronics Labs

 

“Did you ever program an Arduino? Have you ever been worried about complex control flows written in pure C? Maybe you have already heard of statecharts and state machines?

YAKINDU Statechart Tools for Arduino is based on Eclipse, YAKINDU Statechart Tools, and the Eclipse C/C++ Development Tooling (CDT). It sets up an initial project containing an empty statechart that you just need to fill with your own ideas. The only part that you still need to program on your own is the connection between the statechart and the hardware, i.e. initializing the hardware and updating the state of the hardware depending on the state of the statechart and vice-versa.”

DIY Smart Glasses

DIY Smart Glasses

 
HARRIS’ ELECTRONICS is developing a prototype set of Smart Glasses. This is not an easy task! You can read about the development challenges here.

Thanks for the tip James.
“The glasses themselves are based around an STM32F051K8 microcontroller (LQFP32 for easy soldering!). All the firmware is custom written though I got the LCD driver initialization codes from the BuyDisplay examples. The firmware is written using a somewhat “co-operative scheduling” with interrupts methodology and for most of the time, the microcontroller is sleeping until something needs to happen. Along side all the Bluetooth and LCD software, I’ve included my SoftTouch library for the two touch buttons on the side of my glasses. These are used to change screens and change items within the screen e.g. move to the next news entry.”

Custom Word Clock

at 1:28 pm. Filed under Cool Gadgets, DIY Hacks

Custom Word Clock_1

 

Jeremy Blum built this Custom Word Clock. It has lots of non electronic parts such as the great looking case. Good thing Jeremy is no longer at Google and is now working at Shaper with use of a wood working shop. We have seen lots of word clocks here in the past but the main thing I like with this design is the LED panel based design. Most designs use either individual LEDs or addressable LED strips to provide the illumination, with the panel method it removes this large headache.

“I wanted to control the whole thing with a Raspberry Pi and Python. Why? I want to be able to use the clock as a platform for Leah and I to do some Python hacking. This word clock functions fine without an internet connection, but using a Pi makes it easy to hook up to the web for adding future features like a web interface to set an alarm clock – future expansion options! ”

IOT Long Runtime

at 6:18 pm. Filed under Cool Gadgets, DIY Hacks, Educational, Electronic Hacks

 

 

With the adoption of IOT long runtime on battery power is something that is a huge concern. We don’t mind charging our smartphones daily but if we have a dozen IOT devices in our home we would like them to be invisible and just operate for as long as possible without needing attention. Andreas Spiess has done some research using the popular ESP8266 and a variety of batteries. In his test he was sending data to an IOT database every 2 minutes but for many cases you may only need the device to wake and transmit once per hour, this would greatly extend the battery life.
