I will be using two Custom firmware routers to get full house coverage on a very old house with thick lead filled walls. The entire project took 6 hours due to some unexpected issues we faced. You can flash any device below as well to Merlin custom firmware but its entirely optional. This will work with the stock firmware.

I decided due to the lack of community support I am not going to make a Zigbee 433mhz chip instead I will continue my efforts with the WiFi esp8266. Now that I have the 433mhz working with the esp8266 I will be performing some distance testing with a few receivers I purchased and different antennas I have.
Very few people know that you can save yourself some money by buying a T-mobile router on Amazon. Downside is having to flash it to have the latest firmware free of vulnerabilities. In this guide I will show you how to flash a TM-AC1900 to a RT-AC68U then into merlin custom firmware. I have tested it myself and can confirm that it works.
I wanted to talk about my smart home setup from the ground up. I have many articles describing my setup in pieces but not everyone gets an entire overview of everything I have setup here. I don’t have a mansion or anything fancy like built in sprinkler/irrigation, so this will be more catered to your average city home.
Google Home and/or Mini manage my random routines that aren’t part of a automation rule. Going to the basement to do laundry, or going to sleep at random times. I can just send a command and google home will handle it. Link your SmartThings account and Google Home together for best results. Give all your devices aliases to make it easier to command via Google. I want one located in every central room of the house, Kitchen, Living room, Master Bedroom.
What controls my entire setup and why I chose this hub vs others. My only hub is a Samsung SmartThings hub. This manages just about everything in my home minus the security cameras. I did heavy research on many hubs including Wink, IOT (hub-less), and Phillips hue. Why SmartThings?
For Christmas my mother got a full smart home kit. Samsung SmartThings, sengled bulbs, google home. After pluging everything in the hub was having issues. Finding all bulbs in dome covers. I removed the glass from the dome cover and tried again with no luck. Afterwards I removed the bulb from the socket and put it in a lamp. Detected and added to smartthings fine in the lamp. Readded it to the dome cover and it works now!! Seems all I had to do is add it to the network beforehand so that it joined the zigbee mesh network. Has anyome faced similar issues?
How to get a cheap smart home that actually works. Vision Micro switches lets you use the old fashion switch and also continue to use your old bulbs. Instead of paying $10-30 per smart bulb, you pay around $25 for a single or $30 for a 2 relay switch. 2 relay switches help you save a ton more money, you can use one for 2 gang boxes saving you 2x more money ($15/switch). If you think about it, most ceiling lights have 2-3 bulbs, Why buy so many bulbs when you can buy a single switch.
I have found a neat little alternative to full price switches online. I gave myself a budget of $20 per wall switch for the house and until I found something around that I was not gonna buy any. I just think that $50 for a wall switch is a little ridiculous in my opinion. These switches are still over my max budget but at least I found a reason for one of the partners here to buy it instead [bana0615]. He has a double switch in his house and they do not sell double smart switches anywhere. This micro controller solves his problem. The double switch relays will put me under budget for some locations in the house though with the ability to work for two switches at once.
Cant wait to show you what we have in store, new generators coming soon!
We received our new print bed from eBay/China. Not a Lokbuild but at least its cheaper. First thing I noticed is that this sheet is thicker than a Lokbuild, 0.6mm thick instead of 0.5. When I followed the steps on calibrating I clicked
6 8 times to ensure proper spacing instead of the original 4.
1. Launch AutoMaker software and navigate to Calibration button
2. Follow instructions until asked to insert paper between nozzles and build plate
3. Follow instructions and raise nozzles to point at which paper moves freely between nozzles and build plate
4. Set height
4 6 8 clicks higher than this point (i.e. 0.4 mm)
5. Proceed as normal
A friend at work asked if I could help solve his issues with his water intake from the well. At first I was like um why? Living in the city I did not know anything about how country side water systems worked. Water pumped from a well has a chance that it may contain too much sulfur making the water smell. He wanted to pull rain water into a tank and use it as primary with the well water as a failsafe.
I am thinking about using a basic ESP8266 along with a couple of water pressure sensors and relays triggering the water pumps he already has. The code should be very simple to write and I already have most of the hardware here minus the sensor.
