As you’ve been getting your OpenLogger units and starting to get them up and running we’ve been getting a lot of great questions. In this update I’ll go over some answers to common questions, review some great resources, and answer the question I’m sure you are dying to to know the answer to, How much does your toast cost.
As you all know, we wanted to get OpenLogger hardware in the hands of backers as soon as possible. We decided that in order to make this happen, we would send the hardware as soon as we had some basic functionality, and then release firmware updates as we complete major functionality. I’ll announce when new firmware is posted in updates.
To get your OpenLogger up and running, go through the getting started guide located here.
If you are looking for the pinout diagram, reference manual, or any other resources those are located here.
With the current release of the firmware the OpenLogger can stream data over USB to WaveFormsLive.com. We are in the process of testing and refining logging to the SD card so we can get that out in our next firmware update. After that we will follow the order from our first update:
We expect to have all listed functionality complete by the beginning of April.
If you have any technical questions while getting your OpenLogger up and running, you can post them at forum.digilentinc.com where our engineers are ready to answer any questions you might have.
A common debate at my house is how much energy is being used by what devices, and how much does that cost. For example, how much of the electric bill is due to my electric car. In order to answer that question we need a device that can stream or log data for an extended period of time, something like, the OpenLogger!
With the use of all 8 channels and some current sensors, we can make some great comparisons of different devices in our home. For simplicities sake, we decided to answer one question, how much does it cost to make a piece of toast.
In this project https://www.hackster.io/arthur-brown/measuring-power-consumption-with-the-digilent-openlogger-b5cdcc Arthur sets up the OpenLogger with a current sensor, and his toaster to log the current usage during the process of toasting a piece of toast, and calculates power usage, and then how much it costs. Spoiler Alert: It costs less than a penny.
