For Hackaday readers who don’t spend their free time underwater, nitrox is a blend of nitrogen and oxygen that’s popular with scuba divers. Compared to atmospheric air, nitrox has a higher concentration of oxygen; which not only allows divers to spend more time underwater but also reduces the risk of decompression sickness. Of course when […]

I’ve had a Siglent SDS1102CML two channel 100 MHz bench scope here for the last two years. I demand a lot from my test equipment so had low expectations when it arrived. After all, how good can a $359 unit be? Turns out, quite a good for the price. I reviewed it here. But the
Cost and availability of retirement villages cause aging people to stay in their own homes. This system monitors their daily events.

The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked “Who in their right mind would choose a computer interface standard that uses ±12V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop isolation?” Yet, here we are
A new way to save lives by neutralizing the attacker before he can act. Story Our Vision of the Product Our vision for WISdome is a network of weapon owners, providing extended functionality for weapon maintenance and security through IoT. The product will mount weapons and connect to nearby Wi-Fi hotspots, sending information to our cloud. We

Opening 26 pieces of windows at the same time in a 2,000-square-meter greenhouse under just 20 seconds? Yes! Story 2 years ago I decided to step to a new level in controlling micro-climate in our thermal water heated greenhouses. Before that time for example we did all airing by opening-closing windows manually. It was a
All of the tools you need to work with the FPGA Arduino — the Vidor — are now in the wild! . We reported earlier that a series of French blog posts finally showed how all the pieces fit together to program the FPGA on the Arduino MKR4000 Vidor board. Of course, I wasn’t content to just
An internet-connected, easy to use PCR Thermocycler designed by high schoolers, for high schoolers. Story What is a PCR thermocycler? A PCR Thermocycler is a device that can change between desired temperatures in a controllable manner in order to properly carry out a Polymerase Chain Reaction(PCR). What is a PCR? A polymerase chain reaction is

The Arduino Uno WiFI Rev2, available now from RS Components, comes with a brand new 8-bit microprocessor from Microchip, and an onboard IMU. The WiFi connection is made secure with the new ECC608 crypto chip accelerator. The kit has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs,
If you’re like us, you probably spend more time browsing Reddit than you’d like to admit to your friends/family/boss/therapist. A seemingly endless supply of knowledge, wisdom, and memes; getting stuck on Reddit is not unlike looking something up on Wikipedia and somehow managing to spend the next couple hours just clicking through to new pages.
