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!
Kevin

Perfect device and best deal on the internet.

For trigBoard - Ultra Low Power ESP8266 IoT Platform

If you can't think of 8 different ways to use this board, you aren't trying. This is a versatile device to sense an open circuit and send push notification from a tiny, device powered by a super long lasting battery and an extremely low power device. I have deployed these for gate status, door status, and 120vGFI live or flipped socket status. They work great out of the box but the maker who sells this also makes the firmware available for modification.

Awesome

For Cheater Board-ATMEGA328 Breakout and Pinout Helper

Great product, super fast shipping. The only thing I would suggest is to move the ICSP header to be offset (or moved out away from but that would make the board longer) from the end of the 28pin socket so we can get a little bit more access to the end of the socket. With how close the ICSP header is to the socket it makes it difficult to get your chips out even with a chip puller. Im just going to make sure I dont fully seat the chips in these so they will come out easier. I like the labeling on these, I clear coated mine so they wouldn't wear off easy just in case. I made a socket for the crystal to sit in, so I can use these to burn a bootloader for any speed/voltage of the 328. Will definitely be back for more though, freed up some breadboards and some bench space. Thank you.

A pleasure to use

For trigBoard - Ultra Low Power ESP8266 IoT Platform

Been watching Kevin’s videos on YouTube for a while. Grabbed a couple of the trig boards when they became available. Very nice. First one is installed in my mailbox. Second one is waiting for a fun project idea. If you know anything about Arduino, between the videos and the wiki for info, you can’t go wrong with the trig board.

Trigboard V7... expectations met

For trigBoard - Ultra Low Power ESP8266 IoT Platform

I moved to trigboard Ver 7 to use PushSafer rather than the version 4 Pushbullet notifications.
PushSafer is German internet based service to push notifications. I find it fast and reliable.
From the mailbox to actual use with the preconfigured trigboard load took 15 minutes or less.
As for user configuration the version 7 trigboard is much improved over version 4.
