Build your own 4DOF robotic arm on a budget
Reading Time: 2 minutesRobot arms are very cool and can be quite useful, but they also tend to be expensive. That isn’t just markup either, because the components themselves are pricey. However, you can save a lot of money if you make some sacrifices and build everything yourself. In that case, you can follow Ruben…

Move Mario remotely with this online N64 controller system
Reading Time: 2 minutesFor obvious reasons, video game console controls provide input commands directly to the console. Modern consoles may do so wirelessly, but the effect is the same: direct input. But what if you connected a “controller” to the internet? Then you could play from anywhere and that is exactly what Redditor Lovelyroyalette achieved…

This Kenyan engineer modernizes vintage cars with a custom ECU and EFI upgrades
Reading Time: 2 minutesThe automotive industry’s switch from carburetion to fuel injection was one of the most effective advancements of the 20th century. Electronic fuel injection allows for precise control over an internal combustion engine’s air-fuel mixture, which dramatically improves fuel efficiency and performance. But that requires computer oversight, which is why Kenyan engineer Peter Mbiria…

New backscatter technology promises cost-effective reliability
Reading Time: 2 minutesTraditional bi-directional wireless communication requires both a receiver and a transmitter at either end. Your laptop, for example, needs to receive a signal from your Wi-Fi router, but it also needs to transmit a signal back to that router. That transmission requires power proportional to the strength of the signal, which is…

This robotic dispenser will tell you if you forget to take your pills
Reading Time: 2 minutesMany types of medications (such as anti-depressants like SSRIs) can have a very negative effect if they aren’t taken on a regular basis. Even taking them a few hours late can harm a person’s mood and cause physical discomfort. But remembering to take pills at the proper time can be tricky —…

Computer vision and project mapping enable AR PCB debugging bliss
Reading Time: 2 minutesImagine if you could identify a component and its schematic label by simply touching that component on your PCB. Imagine if you selected a pin in KiCAD and it started glowing on your real, physical PCB so you can find it easily. Imagine if you could see through your PCB’s solder mask…

Mole crab robot burrows into sand using flexible legs
Reading Time: 2 minutesRevolutionary new technologies tend to require small, incremental developments. For example, physicist Julius Edgar Lilienfeld filed a patent for a transistor way back in 1925. But it wasn’t possible to actually build transistors until semiconductor production caught up in 1947 — something that took decades of “boring” materials research. Such research may…

Real Robot One is a high-performance robotic arm that you can build yourself
Reading Time: 2 minutesArduino Team — August 15th, 2022 Robotic arms are versatile machines and are great for learning about principles of robotics or even doing useful work for hobbyists. That work might be picking and placing components on PCBs, packing boxes, or anything else you can imagine. But to perform that work well, the…

Centimeter-scale lawn mower positioning without GPS RTK
Reading Time: 2 minutesArduino Team — July 27th, 2022 GPS is perfect for navigating roads, because that doesn’t require much precision. But GPS is only accurate to several meters, which means that it is unsuitable for applications that require more precise positioning. GPS RTK (real-time kinematic) systems can achieve much greater accuracy, but they are…

Schematic-o-matic automatically creates KiCAD schematics from your breadboard
Reading Time: 2 minutesArduino Team — December 3rd, 2021 Breadboards are the first tool you break out in any prototyping journey and almost every project will utilize a breadboard at some point. Those breadboards often turn into a rats’ nest of overlapping wires that are difficult to trace, which makes it difficult to create an…

Low-cost, highly accurate piano tuner made with an Arduino Due
Reading Time: 2 minutesArduino Team — October 28th, 2021 Electronic instrument tuners have existed now for several decades, but the ones with a great amount of precision can cost over a thousand dollars to the consumer, which is far above what many are willing or able to pay. To address this issue of high prices…
