Most people reading this will be familiar with the Digital Equipment Corporation (DEC) lines of PDP machines. I would guess though that far fewer have encountered the H-500 Computer Lab. Launched in the late 60s the H-500 was part of a COMPUTER LAB curriculum to introduce students and engineers to digital electronics. It's not surprising that DEC would undertake this since more than half of its PDP machines at the time were installed in educational institutions.
The machine itself shipped with a wonderful workbook that contained a complete course in digital electronics. Together the COMPUTER LAB package was intended to accompany courses in binary arithmetic, Boolean algebra, digital logic or computer technology. While not a true computer, the H-500 could be "wired" to perform many of the underlying operations of a true computer using a point-to-point patch cord mechanism.
Michael's builds have been previously featured on Boing Boing:
TheBackyardScientist built out a 200 watt laser and mounted it on the roof of his car. In his YouTube description, he wrote three paragraphs about why this experiment did not endanger any airplanes. Previously, he built a handheld 40 watt laser blaster:
Three years ago, Ian Davis was diagnosed with a cancer that weakens the bones. Shortly after, the engineer had an accident in his machine shop that resulted in physicians amputating four fingers on his dominant hand. “When I was still in the hospital I started designing a prosthetic hand,” Davis told KOBI News last year.

In the late 1950s, a truck carrying a cement mixer crashed on E300 Road between Talala and Winganon, Oklahoma. Apparently too heavy for anyone to deal with, the mixer sat for decades where it was occasionally graffitied or whimsically decorated. In 2011, artists Heather and Barry Thomas celebrated their wedding anniversary by transforming the drum […]
As the world has shifted the last few months, it’s very likely your assortment of EDC items has changed too. While you’re still looking to slim down the number of items you have to tote around every day, there’s a good chance you’re keeping an even tighter focus on how safe those items are and […]
Building blocks are among a child’s first, and arguably, most important, toys. Once they start stacking one tentatively on top of another, the blocks not only spark waves of creativity, but actual real-world understanding of scientific principles like engineering and physics. It wouldn’t even be a stretch to call blocks on of the first true […]
Time management and self-motivation, the ability to stay on task and achieve in the office or when you’re working with home, is the true test of any person’s professional mettle. While that’s easier said than done, those skills can be taught and developed as you’ll find in The 2020 Work From Anywhere Hacker Bundle. The […]
