HP LaserJet 1020 plus working fine with TL-WPS510U wireless print server We have an HP LaserJet 1020 plus which we wanted to share on our network. Since this is a printer which only has a USB port, it can be shared by connecting it to a windows computer and sharing the printer via homegroup . But this required us to keep the connected computer on all the time. So I decided to try out the TP-Link Wireless Print Server TL-WPS510U . In India it costs around ₹5000 and so it makes sense for anyone to go for this device to retro fit your old printer into a a network capable one. But there is a caveat. The supplied CD which allows you to configure the software won't work on any PC. The TL-WPS510U is configured to join an "Ad-Hoc" WiFi network named WLAN-PS. The supplied software on your CD, makes your PC join this Ad-Hoc network and then sends commands and credentials to the TL-WPS510U over this Ad-Hoc network and instructs it to join to your home/office's WiFi net...

So here is a modified version of how to get a DHT22 working on ESP8266 NodeMcu board using the Arduino IDE (not Lua) The project is based on: http://randomnerdtutorials.com/esp8266-dht11dht22-temperature-and-humidity-web-server-with-arduino-ide/ Get the components and assemble them. In India you can find these on VishaWorld.com NodeMcu ESP8266 | Link DHT22 |  Male-Male Jumper Wires |  Bread Board | Link MicroUSB cable |  Assemble the circuit as shown. Connect the Data pin of SHT22 to D2 of NodeMcu (which is referred to pin 4 in Arduino IDE) Install the driver for USB-Serial chip on your PC: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx Install Arduino on your computer and install support for ESP8266 Board, refer: https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide/installing-the-esp8266-arduino-addon Install the DHT-sensor-library-master library as outlined here: http://randomnerdtutorials.com/esp8266-dht11dh...
