Details

Perfectly sized for your wallet, this printed circuit board has a beautifully silkscreened resistor color chart on one side, and a comprehensive SMT reference on the other.

"Apparently they used eight colors during the screen printing process–impressive for a PCB!"

The Amp Hour

"Octopart has a handheld tool for referencing footprint sizes and reading resistors. It’s made out of FR4 and has some serious silkscreening!"

"Never leave home without it!"

Othermill Backer Update

"[Star Simpson] works on all manner of circuitry from taco-delivering drones to wearables to plush toys for teaching electronics to children. She cares a lot about making circuit design easier for people, as evidenced by her latest project."

No circuit tinkerer should be far from a resistor color chart. We've engineered the perfect chart. It's easy to use, and makes intuitive sense even to beginners. Reading the chart is super fast, just read the colors from left to right, and add in a decimal point when indicated by the final color's tail.

You thought you could only use one silkscreen color at a time on a PCB, didn't you? You thought wrong. This chart has brilliant, attractive colors. We think we've set a record for the number of silkscreened colors on a PCB: eight!

For those hackers who have said their goodbyes to through-hole parts, the backside of the card features a visual to-scale reference of footprints for common surface mount packages.

The PCBs will be the same size and thickness of a credit card, 3.38" x 2.13" x 0.03" (86mm x 54mm x 0.76mm). Most PCB's are thicker, this one will slide right into your wallet, no problem. The photos shown with the color silkscreening are mockups, but we have already done a prototype run of the PCBs.

This reference board is brought to you by Octopart, the electronics part search site and API for electronic part data.

Risks & Challenges

Since we are pushing the limit of the number of silkscreened colors on a PCB, there is a chance that we'll run into problems with the printing. However, we've been in close contact with a top tier silkscreen shop and we're confident that we'll be able to deliver a quality print.
