Choose the Best Board for Wearables
RAS2025-07-11T16:00:00+00:00This article appeared in Make: Vol. 91. Subscribe for more maker projects and articles! There are plenty of boards to choose for your next wearable electronics project, and ultimately the best one is whichever fits your project’s unique constraints. To help narrow it down, here are five of the strongest contenders, plus a few that are too good to leave out.

Review: xTool F1 Ultra Laser Cutter
RAS2025-07-10T16:00:00+00:00Manufacturer: xTool Price as tested: $3,699 Link: https://www.xtool.com/products/xtool-f1-ultra-20w-fiber-diode-dual-laser-engraver Previously we looked at the xTool F1; this time we bring you the F1 Ultra, a machine that is more of a big cousin than a big brother to the F1. If you are willing to give up the extreme portability for more power, the F1 Ultra is here for you. Unboxing the F1 Ultra is a surprise — it’s big. It has a 220mm×220mm cutting area, not huge for...
New AWS x Arduino Opta Workshop: Connect your PLC to the Cloud in just a few steps
RAS2025-07-10T11:20:27+00:00We’re excited to invite you to a brand-new workshop created in collaboration with Amazon Web Services (AWS). Whether you’re modernizing factory operations or tinkering with your first industrial project, this hands-on workshop is your gateway to building cloud-connected PLCs that ship data – fast. At Arduino, we believe in making advanced technology more accessible. That’s why we’ve teamed up with AWS to help more people take their first steps into cloud-connected industrial IoT, using tools that are reliable,...

This Beyblade battlebot is like a whirling dervish of destruction
RAS2025-07-10T01:01:59+00:00Arduino Team — July 10th, 2025 Battlebots are fascinating, because their builders always manage to come up with unique new ways of destroying opponents while avoiding damage at the same time. Like any good sport, it involves metagaming to develop a strategy based on expected opponent strategies. Ari’s strategy was to make a translational drift (or “melty brain”) combat robot that spins its entire body at insane speeds, which requires some pretty careful engineering. Ari’s contender...

July Trade Shows: Bowl Expo & IAAPA Expo Asia 2025
RAS2025-07-09T21:30:44+00:00With July fully underway, it’s time to take a look at a couple more trade shows that recently showcased arcade games. These are perhaps the most effective way for new products to get intra-industry attention these days, giving manufacturers the best opportunity to present their games in a hands-on way to potential buyers. While we tend to focus on a couple of the larger shows during the year, smaller ones have their value too, with today’s being no exception. We have...
Gadget Cache Road Trip!
RAS2025-07-09T16:00:00+00:00This article appeared in Make: Vol. 86. Subscribe for more maker projects and articles! Last summer I took an epic geocaching road trip to North Dakota. I drove past the majestic painted hills in Theodore Roosevelt National Park, across the badlands, past the colorful fields, all the way to the east side of the state to a one-horse town called Gilby. Gilby may be small but it’s mighty! It contains a rare treasure for those discerning...
Open Source Hardware Certifications for June 2025
RAS2025-07-08T16:00:00+00:00The Open Source Hardware Association (OSHWA) runs a free program that allows creators to certify that their hardware complies with the community definition of open source hardware. Whenever you see the certification logo, you know that the certified hardware meets this standard. Currently the Certification database lists over 3064 individual certifications! In May we added 35 new certifications, from green houses to trackballs, and we were happy to have new and...
Concept Bytes’ coffee table tracks people and walks itself across a room when called

Arduino Team — July 8th, 2025 The term “mmWave” refers to radio waves with wavelengths on the millimeter scale. When it comes to wireless communications technology, like 5G, mmWave allows for very fast data transfer — though that comes at the expense of range. But mmWave technology also has some very useful sensing and scanning applications, which you may have experienced...Building a Wi-Fi robot controller that accepts voice commands
RAS2025-07-07T20:41:54+00:00Arduino Team — July 7th, 2025 The whole point of a robot is that it can operate without direct control input from an operator. Except there are many exceptions and it isn’t uncommon for roboticists and operators to require direct control. The Tinkering Techie needed to add that capability to his rover robot and built his own Wi-Fi controller that also accepts voice commands. Conventional remote control (RC) vehicles communicate through analog radio. But it is...
