Inspired by the Pro Trinket Everyday Carry Contest, this little gadget uses an MLX90614 IR sensor, (hopefully) 7-segment bubble LED display, and a coin cell. With any luck I will also include a transistor-capacitor pair to detect a shake to activate it. I see using this for cooking, determining wine bottle temperature, checking hot water pipes, etc.
All parts for the PockeTemp have arrived, with the exception of the shake trigger components. I want to make sure I have the numbers right so I get enough on-time for the measurement. So instead today I'm readying my cutting files for the IR sensor and the bubble LEDs.
Now, I have access to plenty of enclosure-building equipment: laser cutter, 3D printers, etc. But sometimes, it's the limitations you're handed that really force you to be creative. Take this diminutive Hammond 1551F box. It's really what pushed me into entering the Trinket Everyday Carry Contest. Just look at it! It's terribly cute and ought to fit all the components. It's been unused for years in my toolbox. So, how could I not use it now?
He's not. He's going to detect shaking with a spring making contact with a rigid wire or something, and then use the transistor and capacitor to make the short pulse from that longer. How do I know? I asked the same question three comments down and he answered.
Hey SolamenteDoug! Great project Idea, and It's awesome that you're adding the bike like "spring /transistor/cap" power switch to it! Don't forget to add an image and a project log so you can be included in the first week's giveaway drawing tomorrow - it's happening at 9pm EST on 12/2/2014.
