Thanks Elecrow for a $10 voucher in their Black Friday giveaway. I have heard good reports about their PCB prototyping service, especially the free color option, and I am keen to give it a try.
Exercise bike + magnets + LEDs = festival of light. Devised by T.J.Hunt with specialist engineering expertise from Rabbi Shena Potter Jaffee. Come along 3rd December to the Mayerson Jewish Center of Cincinnati. Pop a beer, grab a latke, and take a spin. Happy Hannukah!
Last week I won the weekly trivia quiz from Tier1Automation, and came dead last in the 43oh Halloween competition with my Jack-O'-Launchpad — but still won the booby prize of 2 MSP430 Launchpad v1.4 PCBs. The freebies arrived in the same post. Good times!
The diagram shows how to connect an Adafruit MAX31855 breakout board to the stripboard Arduino PID shield. Vin should connect to the 5V pin and DO, CS, and CLK to A0, A1, and A2 respectively. Connect a K thermocouple in the screw terminals. If the temperature reading goes down when it should go up, switch the thermocouple wires around.
The graphical user interface allows every feature of the Arduino PID controller shield to be governed remotely via the serial interface. A powerful additional feature is the ability to set multi-stage temperature profiles for applications where the set point changes over time.
