This DIY programmable diaphragm pump is perfect for lab use
RAS2025-07-14T22:57:48+00:00Arduino Team — July 14th, 2025 If you need to move fluid from one vessel to another, you’re probably going to want a pump of some kind. Typical inexpensive pumps are usually only on or off, so you can’t easily control the flow rate. Those that do have some kind of analog adjustment are usually imprecise, which is a problem in lab settings. To solve that problem on a budget, Marb designed a DIY programmable diaphragm...

When Brooklyn, NY-based musician Phillip Stearns found circuit bending, he started experimenting with all kinds of art, branching out from audio into visual, then ultimately into textiles. That one tool, the ability to modify electronics hardware to create things from the resultant glitches, led to his endeavor called Glitch Textiles. “The project started...

Varetta Dillard
Varetta Dillard might be a footnote in R&B and Rock n’ Roll history, having only scored 3 R&B charting records, but her body of recorded work speaks for itself. She was more than just a Ruth Brown impersonator, though she could sound a lot like her idol. Dillard was also part of pop culture, having waxed a tribute record to the recently deceased Johnny Ace (“Johnny Has Gone” in 1955)...July 13, 2025RASUncategorized1950s, Henry Glover, Jump Blues, R&B, Rhythm & Blues, Savoy Records, Uncategorized0 Comments
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...
