Nick Sayer: Making 10ⁿ Isn’t The Same As Building One

December 24, 2015 by Brian Benchoff 27 Comments

Building one of something is tremendously easy. If you’re making one of something, you can cover the insides with hot glue, keep everything held together with duct tape, and mess around with it enough that it mostly works most of the time. Building more than one of something is another matter entirely. This is the thought behind DFM, or Design For Manufacturing. [Nick Sayer] is an experienced seller on Tindie and he’s put together enough kits to learn the ins and outs, rights and wrongs of building not one, but an inventory of things. Check out this last talk of the 2015 Hackaday SuperConference, then join us below for a bit more on the subject.

[Bunnie Huang’s] Hardware Talks Top Your Watch List

October 7, 2015 by Mike Szczys 14 Comments

When [Bunnie] talks, we listen. He is a fount of product engineering knowledge, having seen many of his own products through from concept to market, and frequently helping others do the same. Of course having the knowledge is one thing, but he is also an accomplished speaker who knows what is important and how to share it in a way which is meaningful to others. The latest example of this is a pair of Engineering Talks he gave at Highway 1.

It’ll take you less than twenty minutes to get through the two videos. The first focuses on documentation for manufacturing. What do you need to include on a bill of materials sent to the factory? [Bunnie] has a set of gotchas which illustrate how vital this is. He also discusses how to handle design changes once the manufacturing wheels are already in motion. The second clip covers how Design for Manufacture relates to the actual cost of a production run. We hope there are more of these clips in the publishing pipeline so we’re keeping our eye on this channel.

The two videos are embedded below and at the time of writing had just a couple dozen views each and only one comment between the two of them. It seems sacrilege to say this, but we agree with that YouTube comment; these videos are gold.

Want to check out one of [Bunnie’s] latest projects? It’s a radio-based interactive badge.

Oomlout’s Guide To Kitting

January 14, 2009 by Eliot 14 Comments

The team at oomlout has continued to post all the methods they use in their manufacturing process. This time around it’s the kitting process: how they actually packaged 30 identical SERB kits in an efficient fashion. We covered their wire cutting bot before, but they’ve got other dedicated machines like a sticker cutter. The stickers are used to remove all the cut acrylic pieces from the laser cutter as one unit. They’ve got some other tricks like using a scale to count bolt quantities, and an egg timer to keep track of the laser cutting. All of their envelopes are printed using a parallel port inkjet that has been modified to work with any thickness paper.

We love when hackers bother to post this much detail about their process. One of our favorites is [ladyada]’s full rundown of how the Minty Boost was created.

A History Of SparkFun Prototypes

If you haven’t checked out SparkFun Electronics’ prototype collection yet, you’re missing out. They unearthed many of their old prototypes and published them to show what kind of mistakes could be made. You’ll see plenty of errors and get hints on what to look for while developing your own hardware. This pairs well with their Design for Manufacture post. Along with the pile of broken board iterations, they also walk through how the company developed. Finally, they specifically cover the individual iterations of the BlueSMiRF.

One of the interesting modules in the gallery that never saw full release was the SparkFun Toys line pictured above. The individual units used the standoffs as the power and data bus. The four posts were arranged so they could only be connected in one orientation: power, ground, TX, and RX. It’s an interesting idea that seems like it might be worth exploring further. SparkFun says that it worked fine, but didn’t feel they had the resources to market it to the intended audience.
