Aligni Wants To Let You Use Their BOM Software For Free

As Bunnie pointed out on his blog, managing the Bill Of Materials (BOM) for a project can become quite complicated. Even a simple project, if it needs to be manufactured by someone else, would benefit from a BOM-specific tool

One such tool is Aligni, a web-based tool that can be used to construct the entire BOM, coordinate with manufacturers and manage inventory. Oh, and Aligni wants to let open source projects use the site for free.

I interviewed Jake Janovetz on what Aligni can do for open source hardware.

Can you give me some background on where Aligni came from and what it’s been used for?

Aligni was created out of a need to manage parts for a small electronics company.  Everything on the market was either too big (SAP, Oracle, Agile, Arena PLM), dead (Parts & Vendors), or would not handle inventory (Agile, Arena, etc).  We wanted a one-stop shop to handle things from design, part management, BOMs, cost info, inventory, assembly management, quoting, and purchasing. Interestingly, some products out there solved some of these.  QuoteFX is a widely used platform for doing quoting via database.  I think it runs in the $100′s per month per user.  Which is absolutely ludicrous.  It’s just a piece of what Aligni does and we do it much better!

What open projects have used Aligni successfully?

Unfortunately, none, really.  Some small projects have started and left over the years.  We haven’t really pushed hard on Open Aligni.  The commercial version of Aligni has lots of successful companies using it.

What do you, or the Aligni team, think about open hardware in general? How do you think it compares to the proprietary approach? Strengths and weaknesses?

We love open hardware.  As it has become better defined over the years, it is easier to talk about it.  Early on, it was confusing what it really meant.  Both open and proprietary are very valid.  In particular, a corporate entity will often get a lot of value from using proprietary hardware.  It’s simply a matter of motivation and accountability.  But Open Hardware is profoundly useful and disruptive (that’s a good thing). We originally introduced Open Aligni because we felt Open Hardware lacked a venue and a proper presentation.  The Open Hardware projects out there tend to cobble together some Google Docs or spreadsheets or other things in an inconsistent and hard-to-maintain manner.  Aligni is a more structured, disciplined approach to presenting hardware designs and managing them.

Bunnie’s Factory Tour Part 1: How To Make A BOM

Bunnie Huang posted an extensive explanation of how you’re doing your Bill Of Materials (BOM) all wrong. Here’s a taste. For the whole 5-course meal head over to his blog.

Most Makers trying to scale up quickly realize the only practical path forward is to outsource production.

Every single assumption, down to the color of the soldermask, has to be spelled out unambiguously for a third party to faithfully reproduce a design. Missing or incomplete documentation is the lead cause of production delays, defects, and cost overruns.

Here’s some of the things missing from the [typical] BOM:

  • Approved manufacturer for each component
  • Tolerance, material composition, and voltage spec for passive components
  • Package type information for all parts
  • Extended part numbers specific to each manufacturer

A complete BOM for an LED flasher also needs to include the PCB, battery, plastic case pieces, lens, screws, any labeling (for example, a serial number), a manual, and packaging (plastic bag plus cardboard box, for example). There may also need to be a master carton as a single boxed LED flasher is too small to ship on its own.

Bunnie’s Totally Open Source Laptop

Andrew (bunnie) Huang, who won the Electronic Frontier Foundation’s 2012 Pioneer Award (for something different), is currently testing the first version of his open source laptop hardware.

It’s about 120mm by 150mm by 14mm nad it has a small battery board so it should be able to fit into an average sized laptop frame (yet to be designed). Nearly the entire motherboard is open source; only a couple things required closed source firmware and the board is bootable without them.

One of the things I love about open source is that people don’t tend to worry about anything other than the best possible solution. They don’t try to design in some sort of crippling restriction that will lock in customers. Like, for example, Apple arbitrarily redesigning their docking port and then telling developers they can’t use it in their device if it includes ports compatible with anything else. Bunnie not only used a standard SATA-style port to connect the battery and mother boards but he also make the connection for the battery itself a standard molex so you can use cheap, commonly available RC vehicle batteries.

At the moment he’s apparently running through the tedious process of validating all the board’s functions, but that highlights another thing I love about open source. Down in the lengthy comments beneath his post it was suggested that he include a physical kill switch for the microphone and camera. Bunnie hadn’t thought of that, but recognized it as a good idea, and is planning to add the feature. It would take a year to get something like that changed anywhere else and that’s assuming the developers ever heard about a good user-submitted idea.
