Fwd: Building a Programmable Thermostat with a Nextion Display, Designing Antenna Systems, Single-Chip Four Channel Datalogger, Calculators as Coprocessors
BUILDING A PROGRAMMABLE THERMOSTAT WITH A NEXTION LCD DISPLAY Customizing a thermostat for a simple forced air heating/cooling system.
I realized there were several things I wanted to learn about thermostats. I determined to do some studying and then build one of my own design. Here's what I did.
If You Bought a LINEAR RESISTOR From a Distributor Between January 1, 2003 and August 20, 2015.
To file your claim and receive a payment from the settlement fund, go to LinearResistorsIndirectCase.com or call 888-209-5181 for more information and deadlines.
DESIGNING ANTENNA SYSTEMS The radio antenna and its role in a radio system.
Here are some thoughts on assembling a radio antenna system with a focus on reducing the known variants that are usually either overlooked or that can creep in when you're not looking.
Single-Chip, Four Channel Datalogger A simple data logging circuit for many applications.
This inexpensive datalogger is suitable for just about any application where a small, cheap, low power circuit is needed to sample analog voltages, convert them to digital values, and store a modest amount of data in non-volatile memory.
CALCULATORS AS COPROCESSORS Turn a TI calculator into a computing machine.
Connect Texas Instruments calculators to Arduinos to extend this open source prototyping platform's computing power for math functions and to make graphic capabilities easier to implement.
