Big-box stores have never really been a great fit for selling computers, and a big reason for that is that retailers didn’t initially know how to sell them. Continue reading Did the Big-Box Electronics Retailer Ever Truly Make Sense?

Making on the go is sometimes required in today’s busy lives, and if you find yourself traveling — say, off to university like [ZSNRA] — then a convenient solution is required. To that end, a portable electronics workbench was built in the shape of a relatively nondescript plywood box.
Plywood and foam-core are the main materials used in building this maker’s bug-out box, with two fir runners along the bottom so the case is not resting on the hinges. Inside, [ZSNRA] has packed a staggering amount of hardware which results in an 11kg suitcase.
Here goes — deep breath now: …read more

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I decided to read some books to flesh out what I knew and add to my body of knowledge. It turned out to be hard to find good ones.
The electronics section of my bookcase has a number of what I’d consider duds, but also some gems. Here are the gems. They may not be the electronics-Rosetta-Stone for every hacker, but they are the rock on which …read more
[Jason Jones] has always wanted a curve tracer for his home shop. When he was starting out in electronics he fell in love with a machine called a Huntron Tracker 2000. This machine would feed a sine wave into a circuit on one side and plot a XY graph on the other.
[Jason] figured that with a modern microcontroller such a device could be build simply and cheaply for around $15 dollars. With that requirement in mind he set out to build it. He selected a PIC24F16KM202 for the brain and got to work.
The write-up is really great. It’s …read more

Besides being common tools available to most hackers and makers out there, 3D printing, CNC machines, and cheap Chinese electronics have one more things in common: they were all used by [Nick] to build a bluetooth speaker system that has some interesting LED effects built into the case.
This is fresh on the heels of another hack that used similar construction methods to build a “magic” wood lamp. [Nick] takes it a step further, though. His case is precisely machined in white oak and stuffed with the latest China has to offer: a bank of lithium-ion batteries, a DC-DC converter …read more
As a fresh-faced electronic engineering student while the first Gulf War was raging in a far-off desert, I learned my way through the different families of 74 logic at a university in the North of England. 74LS was the one to use, the story went, because it’s quick and doesn’t use much power. At the time, there was an upstart on the scene: 74HC. Now that’s really quick. New. Exotic, even.
Thus an association was formed, when you want a quick logic function then 74HC is the modern one to go for. It could have been a lifelong love …read more
