Lots going on – to summarize: The recent site breakage was a result of serving mime type ‘*’ as ‘application/octet-stream’, to transfer jpeg images around for the camera project. Bad idea, as it broke this site. Not using atom.io as an editor for this site is a major pain. Now that I have it […]
On a lark I tried accessing the Adafruit JPEG serial camera (a VC0706 module) via the TX/RX serial lines of the ESP-01. And…. it sort of works. The library suggests software serial, and with SoftwareSerial camera connection = SoftwareSerial(3,1); and cameraconnection.begin(38400); the library functions for taking a picture, setting the size, and fetching a jpeg […]
If you are new to electronics you might here a phrase like “Just add a pulldown to that”. Or “Cap the crap outta that.”. In Arduino-land you might also hear “I2C needs pullups on the SDA and SCL lines”. And the advice from the wizards will be something like “Meh, just throw some components at […]
I was using a simple pair of resistors to form a voltage divider to feed bright/dark info from the LED of a USB NiteLite to an ESP-01, and in trying to tweak the design a bit I came across an idea on the Adafruit site: Using a Photocell I’d forgotten about. I’ve used this before on an […]
