BUILD YOUR OWN LASER HARP using Arduino
Posted on: 01 Aug 2026
The laser harp is a musical instrument made of light. A fan of beams shoots up from the floor into the night sky. The performer can create music by placing their hands in the beams. Not only does “breaking” the beam produce notes, but sliding the hand along the beam will also change the sound. […]
Top 10 Flexible PCB Manufacturers in China
Posted on: 31 Jul 2026
Flexible PCB sourcing is often more complicated than it first appears. A flex circuit may look simple because it is thin, but its reliability depends on more than replacing FR-4 with polyimide. The choice of flexible PCB substrate materials affects bend life, dimensional stability, temperature resistance, and electrical performance. Production must also account for copper […]
STEREOLITHOGRAPHY GOES BIG
Posted on: 15 Jun 2026
When it comes to hobby-level 3D printing, most of us use plastic filament deposited by a hot end. Nearly all the rest are using stereolithography — projecting light into a photosensitive resin. Filament printers have typical build volumes ranging from 1,000 to 10,000 cubic centimeters and even larger isn’t unusual. By contrast, SLA printers are […]

IR HACK TURNS KID’S LAMP INTO TEMP DISPLAY
Posted on: 15 Jun 2026
Sometimes a clever hack of an off-the-shelf product can come courtesy of its dismantling and hardware modification, but at other times the most elegant of hacks can be made without ever turning a screwdriver. [Brian Lough] was given the request by a friend to replicate a commercial child’s night light that changed colour with temperature, […]

Evaluation kit for development of battery maintenance free IoT equipment
Posted on: 15 Jun 2026
Renesas Electronics Corporation has launched its RE Family, which comprises the company’s current and future lineup of energy harvesting embedded controllers. The RE Family is based on the company’s proprietary SOTB process technology, which reduces power consumption in both the active and standby states, excluding the requirement for battery replacement or recharging. “Energy harvesting eliminates […]
Stretchable electroluminescent stopwatch display sits like a tattoo on your skin
Posted on: 15 Jun 2026
Unique stretchable electroluminescent stopwatch that sits on the skin like a tattoo has been developed providing an easy way to monitor data from the back of your hand. New research into alternating-current electroluminescent (ACEL) display technology has taken the concept one step closer to reality. While most displays require well over 100VAC to produce sufficient brightness, scientists […]
WELL-ENGINEERED RF AMPLIFIER POWERS HAM RADIO CONTACTS
Posted on: 15 Jun 2026
Typically, amateur radio operators use the minimum power needed to accomplish a contact. That’s just part of being a good spectrum citizen, and well-earned bragging rights go to those who make transcontinental contacts on the power coming from a coin cell. But sometimes quantity has a quality all its own, and getting more power into […]
REAL LIFE QWOP PROBABLY STINGS A FAIR BIT
Posted on: 15 Jun 2026
QWOP was a flashgame released by [Bennett Foddy] in the distant past. Players would use individual keys to trigger muscle spasms in their character’s legs, attempting to sprint as far as possible without hitting the ground. Hackaday alumus [The Hacksmith] wanted to recreate this in real life, and set to work. Initially planning to hack some […]
