Finishing the Wifi Garage Door Project

Finishing the Wifi Garage Door Project

Finished up the Wifi Garage Door project today.  When I posted yesterday about the Garage Controller I wasn’t sure when the relay boards were going to arrive, and sure enough they showed up in the afternoon mail.  After I got them, I had a thought on using the fourth button on in the other box that was wired to a relay but had no purpose.  A little bit of reprogramming and that button will now open the attached garage. The…

Wifi Enabled Garage Door Controller

Wifi Enabled Garage Door Controller

I had been wanting to build something to control my garage doors for quite a while.  With the success of the Fuel Oil Sensor, I figured it was time to make this work.  We have 4 garages with openers, 3 of them on a detached building.  The remotes that came with the openers don’t have decent range to them.  If we’re inside the house and went to close up the garages for the night, most of the time they just…

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…

Custom Mega-Sized Breadboard

Custom Mega-Sized Breadboard

Did you ever want your own mega-sized breadboard? I know I did, but I just didn’t want to pay that huge markup on the manufactured ones.  Especially since you can order the standard MB-102 breadboard for a little less than $2 each on Ebay with free shipping.  The MB-102 breadboards come with two sided tape already attached so you can just stick it where ever.  What I found, is that the tape doesn’t hold for very long, even with cleaning…

LED LightBox from Flatbed Scanner

LED LightBox from Flatbed Scanner

I’ve been wanting to put together a lightbox just for those times when I need to trace something or quickly transfer mounting holes to paper to make a template.  Lastnight I went to sleep thinking about it, but I really didn’t want to build a box, and then try to find glass I could use for.  Glass being the bigger sticking point because the only glass I have laying around was some old garage windows, which I didn’t want to…

Improving the Rotating Storage with Cork Board

Improving the Rotating Storage with Cork Board

After using my rotating storage unit for a while, I hit me that I had wasted space, and I hate wasted space.  The open sides of the unit really needed some cork board so it’s a tack board for reference information.  Simple enough, quick trip to the big blue box and came home with some 1/8″ plywood.  A little cutting, a little painting and little gluing and I have a pair of cork boards. Improved Rotating Storage One one side…

3D Printed Templates

3D Printed Templates

We got a 3D printer a while ago and I found a perfect use for it with my projects.  Making 3D Printed Templates for cutting out openings in project boxes and panels.  I’ve made several that have worked out perfectly for aligning the holes for switches, knobs and LCD displays. A couple of them were designed to fit snugly in a project box that I’ve used a few times now.  There’s two of them, one for the 4×20 LCD and…
