Reliving Heathkit’s Glory Days Through A Teardown And Rebuild

June 26, 2020 by Dan Maloney 10 Comments

In its heyday, the experience offered by the Heath Company was second to none. Every step of the way, from picking something out of the Heathkit catalog to unpacking all the parts to final assembly and testing, putting together a Heathkit project was as good as it got.

Sadly, those days are gone, and the few remaining unbuilt kits are firmly in the unobtanium realm. But that doesn’t mean you can’t tear down and completely rebuild a Heathkit project to get a little taste of what the original experience was like. [Paul Carbone] chose a T-3 Visual-Aural signal tracer, a common enough piece that’s easy to find on eBay at a price mere mortals can afford. His unit was in pretty good shape, especially for something that was probably built in the early 1960s. [Paul] decided that instead of the usual recapping, he’d go all the way and replace every component with fresh ones. That proved easier said than done; things have changed a lot in five decades, and resistors are a lot smaller than they used to be. Finding hookup wire to match the original was also challenging, as was disemboweling some of the electrolytic cans so they could be recapped. The finished product is beautiful, though — even the Magic Eye tube works — and [Paul] reports that the noise level is so low he wasn’t sure if turned it on at first.

We’ve covered the rise and fall of Heathkit, as well as their many attempted comebacks, including an inexplicable solder-free radio and the “world’s most reliable” clock. Looking at these offerings, we think [Paul] may be onto something here.

Heathkit’s New RF Meter: Who Is It For?

June 23, 2017 by Al Williams 25 Comments

Electronic hackers and ham radio operators of a certain age have a soft spot for the Heathkit brand. Maybe that’s why we had a rush of nostalgia when we saw the Heathkit site had a new product. You may recall that Heathkit had gone the way of the dodo until a few years ago when the brand started to resurface. Their latest kit is a precision RF meter which is available on preorder.

Before there were websites and hacker spaces and all the modern push to “do it yourself,” Heathkit was teaching people electronics through kit building. Sure, they were known for ham radio and test equipment, but many people built stereos (hi-fi), TVs, radio control gear, computers, and even robots. All with manuals that are hard to imagine if you haven’t seen one. They were world-class.

Raspberry Pi Hitches Ride Inside Vintage Terminal

March 13, 2017 by Dan Maloney 41 Comments

When a dumpster dive yielded a vintage video display terminal, [dennis1a4] knew just what to do — bring the Heathkit H19 back to life and stuff a Raspberry Pi inside.

The early days of the personal computer era were a time of great market diversity. Everyone was making stuff needed to cobble together your perfect computer, and terminals were among the most important pieces of gear. Lear Siegler, DEC, Wyse — everyone was in on the game. Even Heathkit competed with its H19 serial terminal, which would have set you back a thousand or so early-1980s dollars.

The terminal [dennis1a4] found was DOA, but he quickly determined that a bad cap was shorting out the -12VDC rail. A little extra detective work was needed to get the terminal to both echo characters locally and output them over the RS-232 port, and bam, working terminal. But then what? Raspberry Pi to the rescue! But those old school +/-12 volts swings would give a Pi a bad case of Blue Smoke Disease. After a little voltmeter poking, and through the magic of socketed driver chips, the Pi was talking right to the terminal at a screaming 9600 baud and accessing the Hackaday Retro site on the 80-by-24 mono display.

All in all, a nice hack on a piece of computer history. But just one question: Can it play ~~Doom~~ Flappy Bird?

Heathkit: Live, Die, Repeat

October 8, 2015 by Brian Benchoff 91 Comments

There is no company that has earned more goodwill from electronic tinkering hobbyists than Heathkit. For more than fifty years, Heathkit has been the measure all other electronic kit manufacturers have been compared to. Kits for everything – from televisions to radios to computer terminals – were all sold by Heathkit, and even now, nearly a quarter century since the last kit left the warehouse, there is still a desire for this manufacturer to rise like a phoenix from the ashes. Heathkit lives once more, and this time it might be for real.

In recent years, Heathkit has had a confusing, if not troubled business plan. The company started manufacturing its signature products – electronic kits of every kind – in 1947. Production of these kits ended in 1992, and the company went on for another few years manufacturing educational materials and lighting controls. In 2011, Heathkit said they were back in the kit business, before shutting down a year later.

In 2013, an official Heathkit Facebook page was launched, a reddit AMA was held, and a mysterious stranger in the Hackaday comments section found a geocache placed by someone at Heathkit in a Brooklyn park. Absolutely nothing happened in 2014, or at least no one cared enough to hire a PI, which brings us to today’s announcement: Heathkit lives yet again.

This morning, the president of Heathkit sent a message to the ‘Heathkit Insiders’ email group explaining the goings on and new happenings:

We’ve designed and developed a wide range of entirely new kit products. We authored the manuals for these kits, complete with the beautiful line art you rely on, preserving and respecting our iconic historic Heathkit style. We developed many new inventions and filed patents on them. We relocated Heathkit, and set up a factory, and a warehouse, and offices, in Santa Cruz, California, near Silicon Valley. We built the back office infrastructure, vendor and supply chain relationships, systems, procedures, operations methods, and well-thought-out corporate structure that a manufacturing company needs to support its customers, to allow us to scale instantly the day we resume major kit sales. All this effort enables us to introduce a fleet of new kits and helps ensure Heathkit can grow, prosper, and continue to bring you great new products for a very long time.

The new Heathkit shop features their newest product, the Explorer Jr. AM Radio Receiver kit, a small kit radio available for $150. It’s actually a rather interesting kit with a nice design and an air variable cap for tuning, just like radios from a century ago. Whether anyone will pay $150 for an AM receiver in this century is another question entirely. The 21st century rebirth of Heathkit doesn’t just mean kits; they’re making apps now, with the first release being a crystal design tool for Android.

Virtually everyone in this little corner of the Internet, from Adafruit to Sparkfun, to Make magazine to everyone with a 3D printer owes a debt to Heathkit. This is the company that first turned DIY electronics into a successful business. Heathkit was the first, and they deserve to be recognized as the pioneers of the field.

The Donner Party were pioneers, too; just because you’re breaking new ground doesn’t mean you’re successful. The Heathkit of the 90s shuttered its doors for a reason. The factors behind the 1992 closing – cheap stuff from China, and the fact that not many people want to build their own electronics – are still with us. Still, the market for DIY electronics may be big enough, and Heathkit’s back catalog may be diverse enough that I won’t have to write another ‘Heathkit dies yet again’ post in a year or so. We can only hope.
