I published a summary of my previous scale project. In this project I hacked a postal scale that was purchased off of Amazon. This has been working really well, really the only complaint is that the scale area is smaller than the Hive base so things...
I have perviously written about Sensor Mania, this describes my workflow for coming up with new ideas for sensors and applications. Well yesterday when I received my sound level meter, I thought that a good way to spend the evening would be getting...
Last night I talked about my adventures with ESP8266. In that project, I used the analog_io_lib to receive RF packets from a sensor node and forward them on to data.sparkfun.com using a http get request. This approach is ok, but I really much prefer...
We will begin by placing all the elements required for building this wind turbine including links for where to buy at very competitive price the DC motors that will work as generators and the bearings. - The number of bearings that are needed for the...
Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
Well just because we all know Dave Jones' opinion of "The Internet of Things", it is time to bring his uCurrent to the dark side! Just kidding, Dave if you are reading this, I just thought that it would be a fun project :)I love my uCurrent and use it...
IntroductionI've spent a lot of time showing the MSP430 Sensor nodes and their capability of transmitting BLE packets. I wanted to clarify one thing because I don't think that I've done a great job so far highlighting how exactly this is done.The Sensor...
Limited WiFi RangeThe current Vinduino setup allows me to collect soil moisture data and send it to the ThingsSpeak website, where I can pull up graphs. As soil moisture changes slowly, having graphic capability is extremely helpful understanding the...
ESP01-Wifi-Shield-for-IOT-projects The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs...
Easy-IOT-with-ESP01-WIFI-Shield The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and...
So at this point the MSP430 Sensor nodes are coming along quite well. This week I built and shipped off 10 units to other members of the 43oh.com forum. The first revision of the analog_io_lib was also released and other people are starting to play around...
In the analog.io quarter finals video, I demonstrated an MSP430 Sensor node measuring temperature and humidity then transmitting the data via BLE. I then was using an iPhone to collect the BLE beacons and push them to the internet.In this project update...
Overview: When those summer storms or winter blizzards come rolling in, it can be handy to look at a weather radar to determine their direction and possible intensity. Not wanting to have another open tab on my web browser, I made the Weather Radar as...
Introduction A Buck Converter is a type of DC-DC converter that can step down (i.e., reduce) a higher voltage to a lower voltage. It is a popular choice for power electronics applications because it is efficient and relatively simple to implement.Buck...
