Supercon 2022: Carrie Sundra Discusses Manufacturing On A Shoestring Budget

October 31, 2023 by Navarre Bartz 2 Comments

Making hardware is hard. This is doubly true when you’re developing a niche hardware device that might have a total production run in the hundreds of units instead of something mass market. [Carrie Sundra] has been through the process several times, and has bestowed her wisdom on how not to screw it up.

The internet is strewn with the remains of unfulfilled crowdfunding campaigns for tantalizing devices that seemed so simple when they showed of the prototype. How does one get something from the workbench into the world without losing their life savings and reputation?

[Sundra] walks us through her process for product development that has seen several products successfully launch without an army of pitchfork-wielding fiber crafters line up at her door. One of the first concepts she stresses is that you should design your products around the mantra, “Once it leaves your shop IT SHOULD NEVER COME BACK.” If you design for user-serviceability from the beginning, you can eliminate most warranty returns and probably make it easier to manufacture your widget to boot.

Scratching Out Business Intelligence

August 9, 2022 by Matthew Carlson 9 Comments

At Hackaday, we love things both from scratch and in Scratch, Scratch being the blocks building helpful language for teaching kids and the like how to program. However, when you have a large amount of data that needs to be processed, queried, and collated to get meaningful insights, it is a pain to rewrite a SQL query every time a new question arises that needs an answer. So perhaps a more elegant approach would be to give the people asking the questions the tools to answer them, but rather than teach them SQL, Mongo, GraphQL, or any other database, give them the tools to scratch out the answers themselves.

That’s enough scratch puns for one article. [Tommy] ran into this situation in 2011 and recently wrote about it. Scratch came out in 2003 and has inspired several projects, such as Google’s Blockly. [Tommy] used Blockly to create a web app where users could drag and drop different blocks to form queries. These layouts were passed to a PHP-backed (though later HVVM for performance reasons) and executed as SQL.

Eventually, big data came around, and the company hired proper data scientists. Though [Tommy] notes that some of those who used his tool went on to learn proper SQL and do it themselves. Applying concepts from programs designed to teach children programming might sound a little odd in a business sense, but we love seeing projects that help someone become curious enough to peer inside the machine.

Hardware Project Becomes Successful Product For Solo Developer

November 2, 2021 by Donald Papp 26 Comments

[Michael Lynch] has been a solo developer for over three years now, and has been carefully cataloguing his attempts at generating revenue for himself ever since making the jump to being self-employed. Success is not just hard work; it is partly knowing when the pull the plug on an idea, and [Micheal] has been very open about his adventures in this area. He shares the good news about a DIY project of his that ended up becoming a successful product, complete with dollar amounts and frank observations.

About a year ago, we covered a project he shared called TinyPilot, which is an effective KVM-over-IP device, accessible over the web, that could be built with about $100 worth of parts. [Micheal] found it to be a fun and useful project, and decided to see if he could sell kits. However, he admits he didn’t have high expectations, and his thoughts are probably pretty familiar to most hardware types:

I questioned whether there was a market for this. Why would anyone buy this device from me? It was just a collection of widely available hardware components.

Well, it turns out that he was onto something, and the demand for his device became immediately clear. He’s since given TinyPilot more features, an attractive case, and even provides a support plan for commercial customers. This is an excellent reminder that sometimes, what is being sold isn’t the collection of parts itself. Sometimes, what’s being sold is a solution to a problem people have, and those people are time-poor and willing to pay for something that just works.

It’s great to see [Michael] find some success as a solo developer, but his yearly wrap-up covers much more than just the success of TinyPilot as a product, so be sure to check it out if you’re at all interested in the journey of working for yourself.

Putting Lasers To Work Hack Chat

March 1, 2021 by Dan Maloney 6 Comments

Join us on Wednesday, March 3 at noon Pacific for the Putting Lasers to Work Hack Chat with Jonathan Schwartz!

Laser cutting equipment runs the gamut in terms of cost, with low-end, almost disposable units that can be had for a song to high-power fiber lasers that only big businesses can afford. But the market has changed dramatically over the years, and there’s now a sweet-spot of affordable laser cutters that can really do some work. And while plenty of hobbyists have taken the plunge and added such a laser cutter to their shops, still others have looked at these versatile tools and realized that a business can be built around them.

For the next Hack Chat, we’ll be sitting down with Jonathan Schwartz. He started with laser cutters at his maker space, and quickly became the “laser guy” everyone turned to for answers. With about 10 years of experience, Jon set up American Laser Cutter in Los Angeles, to provide bespoke laser engraving and cutting services. He has built a business around mid-range laser cutters, and he’s ready to share what he’s learned. Join us as we talk about the machines, the materials, and the services that are part of a laser cutting business, and find out some of the tricks of the laser-jockey’s trade.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, March 3 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

The Art Of Nixies Hack Chat

October 26, 2020 by Dan Maloney 4 Comments

Join us on Wednesday, October 28th at noon Pacific for The Art of Nixies Hack Chat with Dalibor Farný!

When they were invented in the 1950s, Nixie tubes were a huge leap forward in display technology. In the days before affordable LEDs made seven-segment displays a commodity, there were few alternatives to the charming glow of the clear and legible characters inside Nixies. Sturdy and reliable, the cold-cathode displays found their way into everything from scientific instruments to test equipment, and even some of the earliest computers and the equipment that formed the foundation of the Space Race sported the venerable tubes.

But time marches on, and a display that requires high voltage and special driver circuits isn’t long for a world where LEDs are cheap and easy to design with. Nixies fell from favor through the late 1960s and 1970s, to the point where new tubes were only being made by the Russians, until that supply dried up as well. Rediscovered by hobbyists for use in quirky clocks and other displays, any stock left over from the Nixie’s heyday are quickly being snapped up, putting the tubes on the fast track to unobtainium status.

That’s not to say that you can’t get brand new Nixie tubes, of course. Artisanal manufacturers like Dalibor Farný have taken the Nixie to a whole new level, with big, beautiful tubes that are handcrafted from the best materials. Reviving the somewhat lost art of Nixie manufacturing wasn’t easy, but the tubes that Dalibor makes in a castle in the Czech Republic now find their way into cool clocks and other builds around the world. He’ll join us on the Hack Chat to dive into the art and science of Nixies, and what’s going on with his mysterious “Project H”.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, October 28 at 12:00 PM Pacific time. If time zones baffle you as much as us, we have a handy time zone converter.

Ask Hackaday: Wink Hubs, Extortion As A Service?

May 7, 2020 by Elliot Williams 142 Comments

Wink Labs just announced that their home automation hub, the Wink Hub, is “transitioning to a $4.99 monthly subscription, starting on May 13, 2020.” Should you fail to pay the fiver every month, you will lose access to their app, voice control, and automations, which is everything it does as far as we can tell.

This is an especially bitter pill to swallow for Hub users, because the device was just that — a hub. It speaks Bluetooth, Z-Wave, ZigBee, WiFi, Kidde, and a couple other specific device protocols, interfaces with Amazon’s Alexa, has a handy Android master panel app, and had a nice “robot” system that made the automation side of “home automation” simple for normal people. In short, with its low one-time purchase price, compatibility with many devices, nice phone app, and multiple radios, it was a great centerpiece for a home-automation setup.

“Nice home automation system you’ve got there. Would be a shame if anything happened to it.”

Tales (and Advice) From Setting Up A Product Line

January 2, 2020 by Donald Papp 5 Comments

Making something that has to get into others’ hands involves solving a lot of different problems, many of which have nothing at all to do with actually building the dang things. [Conor Patrick] encountered them when he ran a successful Kickstarter campaign for an open-source USB security key that was not only shipped to backers, but also made available as an ongoing product for sale. There was a lot of manual and tedious work that could have been avoided, and so [Conor] laid out all the things he wishes he had done when first setting up a product line.

Turning these unprogrammed boards into finished products then shipping them is a big job.

If the whole process is a river, then the more “upstream” an issue is, the bigger its potential impact on everything that comes afterwards. One example is the product itself: the simplest and most easily managed product line is one that has only one product with no variations. That not only minimizes errors but makes supply, production, and shipping more straightforward. Striving for a minimum number of products and variations is also an example of something [Conor] didn’t do. In their crowdfunding campaign they offered the SoloKeys USB device — an implementation of the FIDO2 authentication token — as either USB-A or USB-C. There were also two types of key: NFC-capable (for tapping to a smartphone) and USB only. That is four products so far.

Offering keys in an unlocked state for those who want to tamper makes it eight different products. On top of that, they offered color choices which not only adds complexity to production, but also makes it harder to keep track of what everyone ordered. [Conor] also observed that the Kickstarter platform and back end are really not set up like a store, and it is clunky at best to try to offer (and manage) different products and variations from within it.

Another major point is fulfillment and in [Conor]’s opinion, unless the quantities are small, an order fulfillment company is worth partnering with. He says there are a lot of such companies out there, and it can be very time consuming to find the right one, but it will be nothing compared to the time and effort needed to handle, package, address, and ship several hundreds (or thousands!) of orders personally. His team did their own fulfillment for a total of over 2000 units, and found it a long and tedious process filled with hidden costs and challenges.

There’s good advice and background in [Conor]’s writeup, and this isn’t his first rodeo. He also shared his thoughts on taking electronics from design to production and the more general advice remains the same for it all: be honest and be open. Under-promise and over-deliver, especially when it comes to time estimates.
