Boards are back and more powerful than ever! With fresh offerings from Arduino and Raspberry Pi and powerhouse boards like DFRobot's LattePanda Sigma and Nvidia's Jetson Orin Nano, itÃ?Â[â?¬â?Â[s easier than ever to put epic computing power for your next project in the palm of your hand.
In this issue of Make: we track new trends in microcontrollers and single board computers, and show you the ones we're most excited about. And if you still can't find the right board for you, we show you how to design and manufacture your own custom chips for cheap! Next, use machine learning and Particle to automagically unmute your mic when someone says "You're muted!" Then, use a Waveshare RP2040 board to build a mini oscilloscope for your workbench for about $25.
Annual Boards Guide: Meet the hottest new boards, and compare specs for 80] microcontrollers and single board computers in our annual comparison guide.
Plus, 31 projects:

- Build an optical transmitter for covert communication
- Sew a soft touch panel matrix for wearable electronics
- Super-size classic wooden Froebel blocks for a fun playground experience
- Harvest disposable vape batteries and give e-waste a 2nd life
- Build a metal detector circuit, 3D print a Kirby fume extractor, or laser-cut an emoji fortune teller
- And much more!
Here at Perkology we still manually inspect and grade each and every book that comes into our warehouse to ensure that you know exactly what to expect when you receive your second hand book.
The criteria that we use to grade used books are as follows:
Like New: an apparently unread copy in perfect condition. Dust cover is intact with no nicks or tears. Spine has no signs of creasing. Pages are clean and not marred by notes or folds of any kind. Books may contain a remainder mark on an outside edge, but this should be noted in the listing comments. Any accompanying CDs or DVDs must be present.Very Good: a copy that has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged. Any accompanying CDs or DVDs must be present.
Good: a copy that has been read but remains in clean condition. All pages are intact and the cover is intact (including the dust cover, if applicable). The spine may show signs of wear. Pages can include limited notes and highlighting, and the copy can include "From the library of" labels. Books may have any accompanying access codes for additional or replacement content missing or redeemed.
Acceptable: a readable copy. All pages and the cover are intact (the dust cover may be missing). Pages can include considerable notes – in pen or highlighter – but notes cannot obscure the text. Books may have any accompanying access codes for additional or replacement content missing or redeemed.
