Fixing an ESP-01 Relay board

Fixing an ESP-01 Relay board

I have a project going to use these little relay boards with the ESP-01 Wifi boards.  I ordered 5 of them from a seller on Ebay and got them yesterday in the mail.  Imagine my disappointment when I popped my already programmed ESP-01 in only to find that they don’t work at all. The first thing that I noticed was that the CHPD and VCC pins weren’t tied together so that the board will go active.  Thinking that might be…

Breadboard Helpers

Breadboard Helpers

Just a quick post of a couple of Breadboard helpers that I made recently.  First one is a pair of little meters to indicate the voltage on the breadboard.  In the pictures, one side is plugged into the bus bar of the breadboard.  The other side is plugged into the 3.3v output of my ESP-01 Programming board. The second is a little mount to hold either the 16×2 LCD or the 4×20 LCD displays that I commonly use.  It was…

Wifi Enabled, Arduino Based Fuel Oil Gauge

Wifi Enabled, Arduino Based Fuel Oil Gauge

I had been wanting to have a remote Fuel Oil Gauge for a long time, as it’s really a pain to get down to my basement to check the oil level.  We don’t do automatic fill and only get oil when we need it.  I’ve found remove sensors available, but they seem to be rather overpriced for what they really are, especially the ultrasonic model.  None of them actually give you a good idea on how much oil, they basically…

ESP8266 ESP-01 Programming/Prototyping Board

ESP8266 ESP-01 Programming/Prototyping Board

I started to mess around a bit more with the ESP-01 WIFI boards a couple weeks ago.  I have a couple of projects in mind for using several of them around the house.  As everyone else found, they’re not that easy to work with in their design.  Accessing the pins is difficult without some sort of jig.  I based my board on the design from over at hackster.io.  But I wanted a little more than just being able to program…
