content: Heathkit promised they would make kits again, and their first kit is available.Trouble is, it just doesn't deserve the name Heathkit.It is $129 for a Garage Parking Attendant kit.Very disappointing. The sensors are off the shelf Chinese modules. Very similar ones are available for $3.50 in 50 off quantities.These modules usually have all the electronics built in to turn distances into a pulse width, so the main part of the build is not done by the constructor.And they have even obscured markings on the microcontroller, so it doesn't look like the design is open to the constructor.I built one Heathkit project around the early 70's -a desktop AM/Shortwave Radio - and the care in the design and the documentation was just awesome. The set had built into it everything you needed to fully tune it, and I was really able to understand every part of the receiver. The only things I needed to build it were a soldering iron and a few screwdrivers.Given the brand name with it's great reputation, I just would have expected much more from their first release.Richard.

content: That's just wrong - there must be $20 max. worth of parts in there. Yes - not a Heathkit of yore...

content: Here is the exact radio I built. It basically was the low end shortwave receiver, but it was all I could afford to get from Australia.And this is what people expect from Heathkit. This is the type of kits in the catalog that we dreamt of getting. Even though it is a tube design, if I came across an unbuilt kit like this, I would definitely build it today. The SB-110 6meter 100 watt shortwave transceiver.

content: Quote from: tronixstuff on November 03, 2011, 12:28:16 amI wonder what could a community such as EEVblog could do with a bit of motivation. Imagine all the people and their combined and various talents, instant international distribution network, a lot of quality web presence in sites such as yourself.Or maybe we can think from time to time at some kind of community/club project for internal use and consumption, with input from all the interested people, shared design & manufacturing, etc.Eh, one may dream.

content: yes you are dreaming i think balaur. its been attempted here and somewhere else, search "open source" DMM. things will get messy when more people involved, esp who's not really got the experience of designing things, only talk. the magnitude of complexity of the device shown by OP is so simple anyone (one person! not many) can do alot better than that. i believe with a great dedication, one person can build a Fluke or Gossen. but many person will achieve nothing, just air.

content: Quote from: Mechatrommer on November 03, 2011, 01:25:32 amYes, I know that one. However, I feel that the open source DMM is an exercise in futility. But there are other stuff as well.Cheers,Dan

content: I have been thinking how you could recreate the "Great Kit" experience today, and it is very hard. It is not the same as building a kit from a magazine project, it was something completely different.You were led part by part through the construction, so novices didn't have to panic. All along the way, techniques were clearly explained. A full stepped procedure for powering up, testing, debugging and calibrating was included. Finally, there has to be some kind of service available for the people who stuff up so badly that their kit will never work. As well as being a kit, they were a mini university course as well.Heathkit and others like Sabtronics, Sinclair, University Graham in Australia and many others were able to make these "Great Kits" because the prices of the equivalent products was so high. Production cost markups were just so big, that it was cheaper to sell a kit. People built the University Graham VTVM (Vacuum Tube Voltmeter) in the 60's because it was much cheaper then any built meter of the same quality. Until FETs became available for meters, you had to have a VTVM to get the 10M input impedance you needed.Sinclair in its Scientific Calculator kit around about '74 - the first affordable scientific calculator - were able to offer a 2.50 Pounds repair option to anywhere in the world - so obviously when you paid for the kit, you were really paying for a second calculator board as well that Sinclair would send if your attempt failed.The only successful kits I can think of today are the very specialized custom projects like the 3D printers, quadrocopters, and home DNA sequencing kits where there are no cheap commercial products available right now.If anyone can think of a business model and a product range that would work today, I would love to know.Richard.

content: Quote from: amspire on November 03, 2011, 02:07:44 amWhat about Adafruit? I built their Ice Tube Clock kit and I like the result. It has parts like the laser cut acrylic case that I could not make myself, and it is something you would not find in the shops. There are certainly very detailed step by step instructions, and full help on their forums if you get stuck. Another neat thing is the possibility to modify and customize the firmware (something I am yet to attempt, but I do intend to try it). That too is an added interest you would not get from a commercial product off the shelf.

content: Have you seen the Nanode project done by the London (England) hackerspace?http://wiki.london.hackspace.org.uk/view/Project:NanodeThis is a relatively low cost (20 pounds) kit based on Arduino with extras. They have done documentation and many group build sessions.Perhaps high quality kits at reasonable prices are not dead after all.

content: Quote from: IanB on November 03, 2011, 02:37:02 amThat would be a potentially successful model. Item that have a unique aesthetic design that sell more for the design then the function. In this case, you could also get legal protection against forgeries.

content: Perhaps the only sort of thing a community like EEVBlog could easily design might be something like Arduino shields or Sparkfun-style chip breakout boards. They tend to be small and simple, fairly self-contained, easy for one person to design, and easy for someone else to understand and improve upon, and would lend themselves well to kits. I reckon it's much more fun to solder something yourself than to buy a pre-made one.

content: In regards to Open Source it has been my experience that successful Open Source projects start as one man bands that later get adopted and improved upon by the user base. Committee based Open Source seems to either die or be incredibly slow.Also most projects the hobbyist community are interested in simply aren't of the scale that you need more then about half a dozen main people. That is different to something like a Linux distro which is absolutely massive and can be heavily compartmentalised.

content: Well I wasn't alive to experience Heathkit in its mayday, but by the looks of it, the new Heathkit is not Heathkit at all.It's a new company just riding off the name of something that used to have a good reputation in an effort to maximize profit. Happens a lot these days.But yeah, not even a nice metal case. El cheapo components..and not many of em. Meh.

content: I love the way they Heathkit obscure the part number of the micro as if it is a big secret. Their design might get stolen !!!!!!I mean all the micro is doing is measuring a pulse length and turning a LED on if it is over a threshold. We are probably talking less then 100 bytes of code, including the calibration.Anyone capable of copying the design is probably capable of designing something twice as good.The next kit will be a Wireless Swimming Pool Monitor.They are looking for suggestions for future kits. I think I will suggest a 40GHz spectrum analyzer.Richard

content: Quote from: amspire on November 03, 2011, 02:07:44 amthats how my dad explained it to me as well... kits brought the price tag of otherwise cost prohibitive electronics and test gear within the reach of hobbyists and semi-pros.btw, i found his Heathkit VTVM the other day in the garage. needs some tlc but appears to still function. i had already located his Sabtronics DVM... unfortunately, i let the smoke out of it.-sj
