About

My name is Kevin Darrah and I have a design services company called KD Circuits http://www.kdcircuits.com

One of my passions is teaching electronics on YouTube: https://www.youtube.com/user/kdarrah1234

A lot of the projects and concepts I talk about in those videos are based on my own designs, which is why I'm here on Tindie to make them available for sale.

Thanks for stopping by!

Very happy - works like a charm

For trigBoard - Ultra Low Power ESP32 IoT Platform

I had an idea, looked for a solution to detect water, found the trigboard and ordered it immediately. It was mailed to me the day after and I received it (in Belgium) soon after. So happy already with the service.
Being a complete nitwit in electronics I duly followed the schema on the wiki, and guess what. It works! So very happy indeed.

All great

For trigBoard - Ultra Low Power ESP32 IoT Platform

Item arrived a bit long, but it is expected because of the current pandemic situation.
The trigboard itself is very well designed and built.

What is there not to like.

For trigBoard - Ultra Low Power ESP32 IoT Platform

Lowest power consumption on the market. Kevin did a remarkable job with this product. The documentation and web page for configuration are more than any other ESP32 chip out there. The configuration is easy enough for an 8th grader. I am using one of them (3 purchased) to monitor mailbox and another to monitor ejector pump for failure. Would and will buy again.

I would give this board a "10" if I could.

For trigBoard - Ultra Low Power ESP32 IoT Platform

This is my first excursion into the ESP32 world, so I was a little nervous about programming and configuring the trigBoard. Boy, was that anxiety a waste of time! Since what I wanted was to be notified whenever my mailbox is opened or closed, there were no programming requirements. The firmware on the trigBoard will already do that as is. All I needed to do was mount the magnetic contacts in my mailbox, and configure my wifi information onto the board over Bluetooth. Both were simple and easy. For that reason, I would highly recommend getting the magnetic contacts, battery enclosure, and case at the same time when ordering the board. They are available on the same Tindie site and are inexpensive. Another suggestion is to follow Kevin Darrah's YouTube video with regards to configuration.. I tried different combinations of Windows, browsers, and even my phone's Android. Only Windows10/Chrome/Bluetooth worked successfully. Don't be fooled by using Android to configure the trigBoard. Even though the configuration interface will display on the phone, and it allows you to input all of the information, something gets "mangled" when transferring data to/from the board. All in all, I am very happy with this product, and it works flawlessly.
