Maybe One Of The Most Adorable Obstacle Avoiding Robots You’ve Seen
We’re all pretty well-acquainted with the obstacle avoiding robot. These little inventions use a proximity sensor to detect an object in front of the robot, then circumvent the object accordingly. Brown Dog Gadgets’ little robot really caught our eye, mostly because it’s kind of cute.

7-Segment Display is No Small Feat
The 7-segment display certainly is a popular build, and surprisingly people still come up with new takes on this over a hundred-year-old way to represent numbers. This time [jegatheesan.soundarapandian] is making it big by building a giant 7 feet tall 7-segment display.
Apparently, the plan is to build a giant …read more

SoftCore CPU Comparison
Monty Python once did a sketch where people tried to summarize Proust in fifteen seconds. Although summarizing eight FPGA-based CPUs is almost as daunting, [jaeblog] does a nice job of giving a quick sketch of how the CPUs work with the Xilinx Vivado toolchain and the Digilent Arty board.

Learn the Secrets of Matching Bottle Cap Threads To One Another
Do you want to design something to match existing threads on a bottle, or a cap? It turns out there’s an easier way than reaching tiredly for the calipers and channeling one’s inner reverse-engineer. Bottle cap threads — whose industry term is the neck finish — aren’t arbitrary things; they …read more
Life-Saving Surgery for a Telescopic Antenna
Whether it was as an impulsive youth or an impatient adult, there’s probably few among us who haven’t broken a telescopic antenna or two over the years. It doesn’t take much to put a bend in the thin walled tubing, and after that, all bets are off. So [The Amateur …read more

A Desk Calendar With A Difference
With the office computer revolution now many decades old, many of the items that once stood on a typical desk are now part of history. The typewriter, the Rolodex, and the desk calendar have all been subsumed by computers and mobile phones. This electronic desk calendar is perhaps an exception, …read more
A ZX80 With A Proper Case
A popular project among Hackaday readers is to recreate a piece of home computing or gaming hardware from the past, and in that endeavour we’ve seen some truly amazing projects. Usually they take the form of bare PCBs or custom cases that look nothing like the original, but not [Cees …read more

It’s Time for Watch Clocks to Make a Comeback
Along with all the colorful, geometric influence of Memphis design everywhere, giant wristwatch clocks were one of our favorite things about the 80s. We always wanted one, and frankly, we still do. Evidently, so did [Kothe]. But instead of some splashy Swatch-esque style, [Kothe] went the nerdy route by building …read more
