Community Corner – May 23, 2014 – High-powered IR LED for RasPi NoIR projects and Laser-Augmented, Stepper-Driven Lemonade Stand
Featured Adafruit Community Project

Oliver Krohn shared some experiments with high-powered IR LED that should be useful to those attempting to shoot in low-light environments with a Pi NoIR and more!
IR LED are widely used for illuminating scenes in security or wildlife camera trap projects, incuding those using a Raspberry Pi in combination with the NoIR picam. We were looking for a high-power LED to reduce weight and size as well as power consumption in comparison to an array of conventional IR LED. (read more)

They had us at lemonade + lasers. jeff m has been getting help sorting out his Stepper Shields Lemonade Stand on the Adafruit Forums, and it looks like he is having a lot of fun with this project:
We have functioning hardware, and the Stepper Shields are stacked and work great. We can aim the laser anywhere on the arc of the lemonade conveyor. Our plan is for the customer to choose 3 different products, based on the time and sequence of the laser treatment (plain lemonade, basic laser treatment, and deluxe laser treatment). We will have the customer press 1 of three buttons to make that happen. We’ll figure that out.
…Also, note the inadvertent placement of Simon Monk’s arduino programming book. It is dog eared. If Simon Monk writes it, we will read it. We want a signed affidavit from Dr. Monk that we have created the best lemonade stand in the universe. (read more)
And now they have a cool control panel in progress, below!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
