Surgery on the Arduino IDE Makes Bigger Serial Buffers

It is pretty well-known that I’m not a big fan of the Arduino infrastructure. Granted, these days you have more options with the pro IDE and Platform IO, for example. But the original IDE always gives me heartburn. I realized just how much heartburn the other day when I wanted to something very simple: increase the receive buffer on an ATmega32 serial...

Mergers and Acquisitions: Analog Devices Snaps Up Maxim Integrated for $21 B

Analog Devices will acquire Maxim Integrated for $20.9 billion dollars in stock, as reported by Bloomberg this morning. Perhaps the confusing part of the news is that the Bloomberg article mentions the acquisition will let Analog Devices better compete with Texas Instruments. Wait, didn’t Texas Instruments acquire Maxim back in 2015? Actually, no....

Build an Everlasting Continuity Tester

When you need a continuity tester at the bench, what do you reach for? Probably your multimeter, right? It may surprise you to know that the continuity tester in the meter isn’t all that sensitive, even if it’s the yellow expensive kind. [Leo]’s will beep even if there is 50Ω of resistance in the line. Disgusted by modern commercial testers, [Leo]...

Changing System Architectures And The Complexities Of Apple’s Butterfly Approach To ISAs

Apple computers will be moving away from Intel chips to its own ARM-based design. An interesting thing about Apple as a company is that it has never felt the need to tie itself to a particular system architecture or ISA. Whereas a company like Microsoft mostly tied its fortunes to Intel’s x86 architecture, and IBM, Sun, HP and other giants preferred...

500 Lasers Are Not Necessarily Better Than One, but They Look Great

If playing with but a single laser pointer is fun, then playing with 500 laser pointers must be 500 times the fun, right? So by extension, training 500 laser pointers on a single point must be the pinnacle of pointless mirth. And indeed it is. When we first spotted this project, we thought for sure it was yet another case of lockdown-induced  boredom...

NASA Making Big Upgrades To Their Big Dish DSS43

When it comes to antenna projects, we usually cover little ones here. From copper traces on a circuit board to hand-made units for ham radio. But every once in a while it’s fun to look at the opposite end of the spectrum, and anyone who craves such change of pace should check out DSS43’s upgrade currently underway. Part of NASA’s Deep Space Network...

(Re)Making a ColecoVision

[Leaded Solder] found some ColecoVision game cartridges at a flea market, and like most of us would, thought, “I’ll build a ColecoVision console from scratch to play them!” Well, maybe most of us would think of that, but not actually do it. He did and you can read about the results in great detail since he wrote up two posts, one covering the design...

Making Smalltalk on a Raspberry Pi

Today, you probably don’t think much about object-oriented programming, it’s just part of the landscape. But decades ago, it was strange and obscure technology. While there were several languages that led up to the current object-oriented tools we use today, one of the most influential was Xerox PARC’s Smalltalk language. [Michael Engel] took a C++...

Hackaday Links: July 12, 2020

Based in the US as Hackaday is, it’s easy to overload the news with stories from home. That’s particularly true with dark tales of the expanding surveillance state, which seem to just get worse here on a daily basis. So we’re not exactly sure how we feel to share not one but two international stories of a dystopian bent; one the one hand, pleased that...

Printed TS100 Case Beats the Heat with a Bearing

As we’ve said many times in the past, the creation of custom cases and enclosures is one of the best and most obvious applications for desktop 3D printing. When armed with even an entry-level printer, your projects will never again have to suffer through the indignity of getting hot glued into a nondescript plastic box. But if you’re printing with basic...
