This is the summary post of a project I created as part of element14’s Sci Fi Your Pi Design Challenge: PiDesk.
Over the course of the challenge, a lot of content was created. I experimented with a new blogging approach with which I separated project updates from guides. The guides were kept as generic as possible, so that readers would not be required to know about the challenge to understand the content. With the challenge over, I’ll be renaming the guides and moving them to the appropriate sections of the website, hopefully making them easier to find for others. They will however remain linked in the project updates, so no information is lost in the process.
All posts are available on the element14 website and can be found using this link.
If this is the first time you stumble upon a PiDesk blog post, have a look at the blog posts above. To get a quick idea of what the project is about, have a look at the pictures below.
The collages represent different parts of the project in different stages. The final result is unveiled at the end of this post. To summarise though, the goal was to create a futuristic desk. I did so by integrating things such as LEDs, a wireless charger and capacitive touch controls inside the desk. There is even a computer that pops out of the desk when the correct button is touched!
Featured Adafruit Products!
Stereo 2.8W Class D Audio Amplifier – TS2012: This incredibly small stereo amplifier is surprisingly powerful – able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD). Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it’s incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 Watt) – making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic “LM386” amps! Read more.
Adafruit Trinket – Mini Microcontroller – 5V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!
