So I was going to document the project I posted about back in November, but I got so wrapped up in building and coding it, that I barely remembered to take pictures of the process. So here’s what I did: I found a replica of an old Gothic arch radio, and gutted it. It had […]
So the previously posted code was working well on the breadboarded version of my project, so I started soldering it into a more permanent form. All was working well until I tried to add a volume knob to the audio output, and now all I get is a loud hum in the speaker when powered […]
/* Rotary encoder: Connect the middle pin of the three to ground. The outside two pins of the three are connected to digital pins 2 and 3 Encoder button on pin 4 with a pulldown resistor DFPlayer module connected to digital pins 10 and 11 OLED connected to i2c SCL/SDA */ #include #include #include “SoftwareSerial.h” […]
Ordered an Arduino Nano a while back along with an ethernet shield that plugs right on to it. Finally got around to messing with it last night, and built a prototype tester: What I’m aiming for here is a small handheld device I can use at work to test data jacks to see if they […]
The Hall Sensor finally showed up from China, and I wasted no time in rigging up a redneck gizmo out of cardboard to test it: The Arduino is now reading the pulses from the Hall Sensor (rather than the pushbutton I was using before), and converting to MPH. All other values on the display are […]
Not sure what’s going on with my spinach, in the last week and a half, both of the seedlings have just keeled over. Shock from the transplanting, perhaps? I stuck some more seeds down in the grow media, and they are just starting to poke their leaves out, so there is hope yet. The Salad […]
The other day I was cutting up some red potatoes for some dish I was cooking, and decided to save the end off of one of them, which happened to have a couple of nice eyes on it. I threw it in a flower pot full of potting soil and started watering it and a […]
I’ve got the seedlings transplanted to the coco-coir filled net pots which are suspended in coffee cans full of homemade hydroponic solution. I need to get some real hydroponic fertilizer, but for now I’m using distilled water and some Dollar Store plant food, Epsom Salts, and calcium acetate that I made by dissolving eggshells in […]
So I said I was thinking about messing around with some hydroponics, and I totally wasn’t kidding. About a week ago I started some Lavewa spinach and some Mesclun lettuce, here’s how they are looking this morning: Hmm, could be time to water the spinach, it’s there on the left. A couple of days ago […]
Gah. Shipping from China is so hit or miss. I ordered some various Arduino parts from China, all around the same time. Some got here in a week, some got here in two. Some I still haven’t gotten, so my project is stalled. That’s ok, I’m thinking about messing around with some hydroponics in the […]
