I was trying to flash a TYWE2s chip ESP8285. Bought an FTDI FT232R chip off amazon, two for something like $15… not realizing that I could use a ESP8266 nodeMCU prototype board to do it. Such a simple hack. You may not even have noticed that there’s an “EN” pin. Well, there is… look at…

Had some worn outlets, house is 13 years old… so, turn off the breaker for that circuit, and replaced the unit. The issue was when I plugged one of those “outlet” testers in, it told me I had an open neutral. Well, WTF… I plugged it in the other side, and then a bunch of…

If you got one or two files, just use an online converter… however, if you have several hundred files you wish to convert, use imagemagick. You first need to install it… on OSX, use homebrew. $> brew install imagemagick. this will give you the “convert” command in the command prompt. Now, to do it manually…

I’ve had a duplex automatic document fed scanner for close to a decade. Original a FUJISU Snapscan M1500, which Fuijisu ended support for a few years ago.

Start terminal windows… term 1 – subscriber to the topic “test” term 2 – publish something to the topic “test” Create a user/password edit the file as root, /etc/mosquitto/conf.d/default.conf: Restart test pub/sub in two terminals. That’s the setup of MQTT Tasmota portion:…

I recently swapped servers, as my old one was running Ubuntu 14.04, I decided to just swap out the server completely to Ubuntu 20.04, port the data… hence the recent rsync post. The process was simple: create new server setup apache (vhosts), mysql, php, etc… firewall rules should be the same, so you could use…

Many people now have Amazon echo/dots / Google home / Apple HomePod, smart TVs, smart thermostats, etc… What happens if one of those get hacked? They’re already on your system? they’re authorized and allowed on your network… now what? That’s why you should have a WiFi network dedicated to IoT devices on a separate VLAN.…

It’s been a while since I posted anything… Kids/family have taken up a lot of time. Dylan’s started to ride two wheels, learning about the Pedrin method was a little too easy to teach him. Dylan was in training wheels for a while and was ready, as he could ride a few meters without either…
