Adding a turbo readout to a vintage PC case

Reading Time: 2 minutesIf you are young, you may not remember the turbo buttons of the 1990s. These existed for backwards-compatibility with older games and software that wouldn’t run properly at the blazing-fast processor clock speeds of the time. The turbo button simply told the CPU to run at a slower clock speed that would work with that […]

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 less than ideal […]

A snore-no-more device designed to help those with sleep apnea

Reading Time: 2 minutesDespite snoring itself being a relatively harmless condition, those who do snore while asleep can also be suffering from sleep apnea — a potentially serious disorder which causes the airway to repeatedly close and block oxygen from getting to the lungs. As an effort to alert those who might be unaware they have sleep apnea, […]

Building a dedicated 3D printer hot end controller with the Arduino UNO R4 WiFi

Reading Time: 2 minutes3D printers need to set their hot ends to a very specific temperatures suited to the filament material and keep them at those temperatures throughout the printing process. Most use PID (Proportional-Integral-Derivative) control for that purpose, which modulates power according to an algorithm that prioritizes stability and prevents feedback oscillations. But what if you want […]

Small PoV display uses CD drive motor for high-speed rotation

Reading Time: 2 minutesThe human brain and eyes are imperfect, so your visual perception has a limited “frame rate.” That is somewhere between 30 and 60 frames per second (fps). Most films are 24fps, which is part of the reason they don’t quite look like real life. Once you reach the upper limits of the human visual frame rate, you […]

Clem Mayer created a handheld BASIC computer badge with the Arduino UNO Rev3

Channel your inner Bruce Lee with this DIY reflex coach

Reading Time: 2 minutesVideo games are popular because they provide a clear and reliable loop of effort and reward. If you smash the baddie, you get experience; get enough experience and you level up. But real life isn’t like that and there is little direct correlation between effort and reward, which is dissatisfying. Gamification techniques address that by […]

This timer uses a rolling ball to count the seconds

Reading Time: 2 minutesBefore we had fancy digital clocks — or even spring-driven mechanical clocks — most methods for measuring short periods of time relied on gravity moving something in a consistent, repeatable way. Both water clocks and hour glasses work under that principle. But it isn’t very fun to watch grains of sand fall, which is why […]

Can tripedal robots actually walk?

Reading Time: 2 minutesBuilding walking robots is difficult, because they either need a lot of legs or some ability to balance through their gait. There is a reason that the robots designed by companies like Boston Dynamics are so impressive. But lots of hobbyists have made bipedal and quadrupedal robots, while largely ignoring tripedal robots. To find out […]
