Signal generators are a handy thing to have around the lab. They are perfect for testing inputs on a new hardware design and verifying the behavior of a circuit before connecting all the pieces together. In recent years these lab tools have not only decreased in size but also in cost. The result has been […]

Mobile TV Broadcasts There are a lot of broadcast and delivery methods in use or in development. You can broadcast live TV to cell phones via satellite, terrestrial towers or WiFi networks. Here’s a look at the basic techniques involved in each approach. WiFi/WiMAX This broadcast method streams live TV signals via the Internet. A […]

RK-1 is a wifi enabled mobile robot that you control using your iOS or Android tablet or phone that makes your Arduino projects mobile. I love building and programming mobile robots and because of my love of mobile robots, mobile phones/tablets and the Arduino, I combined them to make a prototype called the “RK-1”. THE […]

“Sneaky, sneaky Apple,” said iFixit’s chief information architect, Miroslav Djuric, in an e-mail announcing iFixit’s teardown of 5th Gen iPod Touch 16 GB. “Thought you could pull a fast one on us by releasing a new, stripped-down version of the current iPod Touch without your customary fanfare? Not on our watch: It’s teardown time.” iFixit […]

Production So, we have the who (the talent) and the what (the script) — and now we need the where (location). As with real estate, location can be everything. Again, there are several choices. Shooting can happen on location, in a studio or both. The decision can be based on the story, the time of […]

UP Under the Hood If you were to strip the rubber coating off the UP, you would find a strip of steel springs that keep the wristband’s shape. Mounted on the strip are the UP’s electronic components. These include a lithium-ion battery, a motion sensor and a vibration motor. On one end of the steel […]

Slewing behavior of op amps is often misunderstood. It’s a meaty topic so let’s sort it out. The input circuitry of an op amp circuit generally has a very small voltage between the inputs—ideally zero, right? But a sudden change in the input signal temporarily drives the feedback loop out of balance creating a differential […]

Choosing an Arcade Monitor and Computer The first thing you need to keep in mind is that the designers of MAME wanted to create a way to preserve video games — the ability to play the games is simply a byproduct. That means that while the goal of the emulator is to recreate the arcade […]

From now, you´ll find in our store the top-quality capacitors from company AVX. A tantalum capacitor may be for many designers a component with a “smell of alchemy”. It´s not used as often as for example electrolytic capacitors, it´s more expensive and it doesn´t hesitate to fire off at improper handling. Despite these facts, it´s […]

Dreamcast History An established leader in the arcade, Sega entered the home market right on the heels of Nintendo. Renamed the Sega Master System, the system known as the Mark III in Japan debuted in the United States in 1986. The Sega Master System used an 8-bit CPU, 128K ROM-based operating system and had a […]
