Analog temperature sensor TMP36 from Adafruit for $2.00 USD.     I’m working on a new project implementing the TMP36 with the ATtiny45. Please stay tuned….  

How to set up a breadboard circuit for ATtiny45 to blink one LED. BREADBOARD CONNECTIONS Connect Power to ATtiny Power positive to ATtiny VCC (+, red) Power negative to ATtiny GND (-, black) Connect LED LED positive to ATtiny Pin 0 (signal, white) LED negative to resistor Resistor to negative power (-, black)   CODE Upload the following code to […]

  When working with multiple LEDs for the same project take a moment to determine how to indicate the polarity of the LED.     Before I begin a project I use paint, nail polish, beads, or bend the LEDs positive and negative leads into specific shapes.     This allows me to quickly and accurately add LEDs to the […]

This years Valentine’s Day tutorial appears more complex than Stabby Valentine or the Hello Kitty Punchy Valentine, but thats just because of the  fancy French Knots! Look beyond the embroidery and you’ll find a basic LED circuit with some hidden gems on how to sew with conductive thread, mark traces, and hide the circuitry. In the end the Heart Pillow […]

  Breadboards – whats going on behind that plastic mask?   Unfortunately most breadboards have a backing material so you can’t see the connection channels.   A side view close up showing the clips inside the breadboard which hold the jump wires in place gives you some idea of how the connection channels are laid out.   To really understand […]

  Whats on my workbench?     One of my favorite circuits! A Maxbotix Ultra Sonic Range Finder, ATtiny45, and a vibrating motor.  

  From left to right Bamboo and Stainless, Silver taffeta, copper taffata, silver non-woven, velostat and bottom left silver lycra.   Alll from LessEMF in Albany, NY.

So many options for 3V CR2032 coin cell battery holders to sew into eTextile projects.

    Inexpensive and super simple to use.  Switch your eTextile projects on or off with a tilt! This one is $2 from adafruit. Digikey has more accurate tilt ball switches. You can make your own by following this Instructable.  

  Are you ready for this year’s Valentine’s Day project? I bet you’ve been waiting all year for this PUNCHY interactive Instructable! Beware tho – eTextile Love Hurts! Unlike last years STABBY Valentine this time – you will have to sew with poky pricky needles. Will you make a badge for your coat or a pillow for your love? Maybe […]
