My own online store is open!

July 12, 2021 Leave a comment

So after some research and putting in some work, I now have my own online store! It’s powered by Square and has a fairly simple interface: A few items that I sell and shipping costs depending on your shipping address. I currently have 3 regions with different shipping costs: within USA, Canada, and rest of world. I will add more regions, I believe up to 6, each with different shipping costs and try my best to get the costs to be more accurate according to the quantity ordered. Anyway, here it is! Please let me know if there’s something I can improve on. If this goes well, I can retire the dated inmojo.com marketplace and the Paypal purchase links.

Reading SDI-12 sensors with your Android smartphones

So if you want to get started with your SDI-12 sensors quickly, you can use your Android smartphone as a display and install a serial port app. Then within a minute, you are reading your SDI-12 sensors already! Watch my short tutorial for Android phones. I’ll investigate how to do this on an iphone and ipad as well and post my findings.

By the way, those 6 customizable buttons are really useful. You can long press it to edit both its name and value to a command. Then you can just tap the buttons instead of typing. You can even type in both M command that starts the data acquisition and the D command that reads back the data. You will need some delays between the commands though. The following is how I configured my serial port app for a better experience with SDI-12 sensors:

Here is the serial terminal program:
