This Kenyan engineer modernizes vintage cars with a custom ECU and EFI upgrades

The 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 developed his own […]

Meet Real Robot One V2: A mini DIY industrial robot arm

Started in 2022 as an exploration of what’s possible in the field of DIY robotics, Pavel Surynek’s Real Robot One (RR1) project is a fully-featured 6+1-axis robot arm based on 3D-printed parts and widely available electronics. The initial release was constructed with PETG filament, custom gearboxes for transferring the motor torque to the actuators, and a plethora […]

New backscatter technology promises cost-effective reliability

Traditional 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 less than ideal […]

This robotic dispenser will tell you if you forget to take your pills

Many 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 — even setting an […]

Computer vision and project mapping enable AR PCB debugging bliss

Imagine 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 to view the […]

Mole crab robot burrows into sand using flexible legs

Revolutionary 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 seem trivial, but […]

Real Robot One is a high-performance robotic arm that you can build yourself

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 robotic arm needs more hardware than we tend to […]

Centimeter-scale lawn mower positioning without GPS RTK

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 complex and require a subscription to a correction service. […]

This special front door controller can be unlocked in several ways

For YouTuber Jroobi, merely walking up to his front door, inserting a key and turning the handle was too simple, which led him to come up with a very unique and high-tech design for a new type of lock. His idea was to combine several different verification/control methods, including codes, RFID and voice, all in a single […]

’80s-style home computer made from scratch using an Arduino Due

As a continuation from his previous Arduino BASIC interpreter project, Stefan Lenz wanted to take things a step further by recreating a home computer from the 1980s with an Arduino Due board and just a few other components. His system combines a 7″ 800 x 480 TFT screen, an SD card reader acting as the disk, and a […]
