Software updates that deliver new “performance optimizations”, “stability enhancements”, etc … they’re nice and all, but you know what I like – new features! Version 1.1 of Adafruit’s Circuit Playground packs in quite a few of those nice new things. Let’s have look, shall we?
• 555 Timer Calculator
Designed to assist in the construction of 555-based oscillators and one-shot delay circuits, the 555 Timer Calc allows you to specify component values and find the resulting frequency/delay, or vise-versa. Those component values are also plugged right into the relevant schematic displayed for your referencing enjoyment.
• RC Cutoff Filter Calculator
Similar to the 555 Calc (though a bit simpler), the RC Filter Calc expedites the design of basic cutoff filters. Did you know that both high & low pass RC filters are calculated using the same equation? You did … ah, very good then. In case you’d like to reference said equation, you can find it shown at the bottom of this calc’s display.
• Microcontroller Reference
Need a pinout for the ATTiny2313? Then the Microcontroller Reference module is your friend, providing zoomable vector diagrams for popular Atmel chips – courtesy of our friends at Akafugu. More pinouts to come – any in particular you’d care to see added?
• Additional Additions
Several other elements have been spruced up as well, including a revamped index menu for iPhone/iPod as well as relevant equations displayed at the bottom of each calculator module. Users of the
iPad 3 New iPad will also notice Playground’s graphics have been thoroughly retinatized (sp?), utilizing 200% more luxurious pixels than prior incarnations. Aah yes, pixel luxury … Oh and v1.1 does include quite a few of those slightly less glamorous enhancement & optimization type changes under the hood.
