Template Program that uses a DS3231 RTC to wake up an Arduino

April 3, 2019 | My Projects | By: Mark VandeWettering

So, my idea is to use a cheap but reasonably accurate RTC chip module based upon the DS3231 chip to periodically wake a sleeping Arduino. I tried getting it working yesterday, but had little luck. I don’t know whether it was Bailey’s insistence on being petted or simple sleep deprivation, but it eluded me yesterday. […]

Baby steps with the DS3231…

Last night, I did a small amount of work on two projects. I applied some Wood Bondo to a couple of bad defects in my garden bench project. I hadn’t used it in a while, and forgot what a pleasure it was. Sanding should be finished up shortly and I’ll definitely have it painted and […]

Brain Fail: How to waste several hours trying to get an NRF24L01+ working on an Arduino…

I must admit to a certain amount of jealousy about people who demonstrate an ability to start and finish large projects. Granted: I have a full time job and that job is not tinkering with my little home projects. But when I see someone construct a complex prototype of electronics, a large piece of woodworking, […]

Last night, the weather was pretty rainy. I woke up a couple of times during the night (once, when my little cat friend Bailey decided to check my breathing and started head butting me around 4 AM) and heard a lot of rain falling on the roof. When I woke up, it was fairly wet […]

Temperature sensing on an Arduino w/o additional hardware…

Last night I began dusting off my solar project a bit. It still seems like we are at the bottom of the atmospheric river, so I don’t think it will be going outside any time in the near future, but I wanted to make some software changes. It uses a pair of temperature sensors and […]

My Computer Controlled Etch a Sketch…

January 29, 2019 | My Projects | By: Mark VandeWettering

I’ve been wanting to make a computer-controlled mechanical gadget for quite some time. When I finally got a 3D printer a little more than a year ago, I began to think of how I might make a device that could direct a pen under computer control. I even took the time to order a CNC […]

Polyphemus Demonstration and Evaluation “Kit”

December 30, 2008 | Hacking | By: Mark VandeWettering

Okay, it’s not really a “kit”, it’s just some directions on how you can wire some commonly available gadgets (like a Nokia 6100 LCD panel or a piezo speaker) to an Arduino board and make a nice little demonstration board. Some good ideas in here. Polyphemus Demonstration and Evaluation Kit | Popular Science.
