Octopart releases free API for developers

Some background - We think that hackers with hardware experience are the best people to build engineering design tools. Unfortunately, it's quite difficult to get startup capital for design tools so there hasn't been much innovation in the space. The end result is that only large well funded companies have had the resources to build design tools. We hope that by sharing revenue generated by the API, we can democratize design software by enabling hackers of all stripes to build new tools.

Do you have any specific ideas in mind that you guys just don't have time to tackle?

We'd love to step aside to let developers build on top of the API. I'd even like to see someone revamp the Octopart UI! Here are some other ideas:

  - a really good project manager (with collaborative features and publishing tools)
  - browser plugins/toolbars
  - ajax circuit simulator
  - an AdSense-type widget to help engineering forums monetize their sites

Finally, I think that each node in our category map needs a specialized UI. Since we have 1000's of categories there's endless room for improvement there. Top of the list are:

  - power supply picker
  - capacitor picker
  - opamp picker

Any other ideas???

A power supply designer would be super-useful. I've designed at least a dozen onto PCBs in the last several years, all pretty similar to a few reference designs. It's a constant pain in the butt to keep up with obsoleted capacitors. I'd love to see a fully general-purpose power supply designer, where I enter a voltage & power and it spits out a working schematic complete with intelligently selected minimum-cost part numbers.

Several of the big voltage-regulator manufacturers (National, Linear, ST come to mind) have software along these lines already, some of which is fairly good. A unified and less cumbersome application would be great, especially if it could pick out passives (caps, as you suggest, but also inductors and freewheel diodes for switchers). National's Webench already does this, but its library of passives is very limited compared to Octopart and many of the parts it suggests are either expensive or hard to find in low quantities.

TI and Linear seem to be pushing their power supply modules lately. They are pretty cool for projects where you don't care too much about mass production cost and space.

Just so you know, the "Cost" link on this page is broken:

Fixed. Thanks.

This looks great! I'm already imagining some quick Python scripts I want to write to help automate component selection

This looks fantastic. This could actually work well with a project I've had floating around in my head for a while.... I better get going on it!

Is there any guarantee on the accuracy of this information? I've run into wrong technical info numerous times, even on datasheets themselves.

Is this info scraped from datasheets or is it just entered into the database by hand?

We have 9M+ parts in our database so we use algorithmic methods to parse and normalize technical information. In general, the data comes from many different sources including increasingly from the manufacturers themselves. We're not parsing pdf datasheets though so datasheet errors won't affect the accuracy of our database.

As you can imagine, it's impossible to guarantee 100% accuracy on 9M+ parts since we can't verify each part by hand. If you spot an error, please send us an email and we'll fix it.

I wasn't really worried about datasheet errors making into the database. I was more worried about OCR problems and human error. It is nice to know that the manufacturers are starting to give you this stuff.

your search engine is very quick and thinking that you're doing faceted search it's incredible. do you use sphinx, lucene or custom search engine implementation?

haha! Thanks! We recently switched from a hacked-version of sphinx to solr. We're using some custom solr features (including some that we're contributing back) but most of the speed comes from solr faceting. It wasn't trivial to setup though - Harish did a lot of work performance tuning solr.
