Quick update
Log from WiFi AC controller
Some of those who have been following this project may have noticed that there haven't been updates for a while. There are two reasons for this.The first reason being that this was a project that was being worked on during 'spare' time at the office...

Build hope?
Log from TrillSat
The twenty 2018 Hackaday Prize Power Harvesting Challenge winners were announced today, and again I did not win a single thing, not even a non-monetary achievement. This is the 3rd loss for TrillSat in a row, and I see a trend here, unfortunately....

When Standards Aren't
Log from SubPos Positioning System
As it turns out, certain control characters do in fact cause issues. I think the reason it worked yesterday was because the string was parsed incorrectly in the ESP8266 and it was causing some unknowns. I did test the following:AT+CWSAP="test\x0a\x0d\x2c\x22","",1,0AT+CWSAP="testAnd...

Embedded Toolchains
Log from SunLeaf
We are using two main embedded controllers. The ESP8266 and the STM32F446RET6. The ESP is going to do most of the 'heavy lifting' for this project. It will need to do over the air updates and manage the data coming in from the STM as well as upload this...

Introducing the BMaC project
Log from WiFi AC controller
Since embarking on the 'WiFi AC controller' project quite a few months ago now, I have learned more than I ever wanted to know about building (climate) control, and seen the scope of what had seemed like a simple project at first balloon in size as a...

Diving into the circuit
Log from Repurposing an old nixie thermometer
Before presenting the boards, I will set down my goals for this project. Non-goals are to make the thermometer work again, or even to reuse the logic chips, the equipment is long obsolete. Thus my interloper UART board previously pictured has been removed...

Low-Power Environmental Sensor
Log from Arduino-Programmable Cortex M4F Development Boards
It has been a long standing goal of mine to create an environmental sensor/data logger that could run on a small battery for long enough to collect data from a remote location unattended for a few weeks for later analysis.I tried first using the Teensy...

Traffic Light Network
Log from E.R.N.I.E
The idea Surrey EARS run an Arduino course every year. When designing this course we needed some sort of extravagant project at the end to put everyone's newly learnt skills to the test. The idea we settled on is a traffic light network. Each student...

HACKLET 104 – TEST EQUIPMENT PROJECTS
Log from Hackaday.io Project
Hardware hackers love their test equipment. There are entire forums dedicated to talking about multimeters, oscilloscopes, signal generators, and other common bench tools. At times it seems we spend more time talking about our tools than actually using...

Incorporating commonly available sensors into the framework
Log from Python Powered Scientific Instrumentation tool
Thanks to the vibrant hobbyist market, several sensors which would otherwise have remained inaccessible owing to their reflow-only footprints, are now available in amateur friendly breakout boards with clearly labeled pins.I bought up a bunch of these,...

Getting it to work
Log from Gecko Node - Wireless Low Power Sensor
After the PCB was mostly assembled, the next step was programming the EFM32. The starter kit board can be configured in software to program an external device. There is also a pin header which includes the needed pins (https://www.silabs.com/community/software/simplicity-studio/knowledge-base.entry.html/2014/11/24/using_an_efm32_start-H9Gy)....

Uploading data to Google Spreadsheets
Log from Internet-of-Things Power Meter
The ESP8266 being an IoT platform it would be suitable to make it upload the power usage data to the cloud.Uploading data to Google Spreadsheets is not the most straight forward task to however: a script (written in JavaScript) must receive, process...

Implementation
Log from Linux-ESPNOW
On the computer Library : A C++ library has been created to handle ESPNOW packets with Linux. You can find it here : ESPNOW_lib. The code also contains a main() that send back every ESPNOW packet received (it acts like an echo).If you want to use this...
