Go forward and admit it: it has been years (possibly a long time) because you’ve been given a enterprise card that you just didn’t simply instantly throw away. If you wish to get in touch with that individual, you’ll go discover them on LinkedIn. However the flipside is that it may be actually troublesome to get potential shoppers to recollect you. The answer is to take it as much as a extra spectacular stage, as Sergey Antonovich did with this enterprise card that options a complete digital drum package.
When plugged into energy by means of its USB port, the enterprise card will boot up. As a substitute of paper, it’s a PCB with printed graphics exhibiting a drum package. Faucet a drum and the enterprise card will pump out the corresponding sound by means of a 3.5mm TRS audio jack. There are capacitive contact pads beneath the drum graphics, so drive isn’t mandatory and a light-weight faucet will do.
The time period “boot up” within the final paragraph was intentional, as a result of this enterprise card doesn’t include a microcontroller such as you would possibly count on. As a substitute, it has an Allwinner F1C100S SoC. That has a 533MHz Arm CPU and 32MB of embedded DDR RAM, making it able to operating a complete light-weight working system. On this case, that may be a Linux working system — although Antonovich doesn’t elaborate on the distro.
As soon as booted, the working system launches the software program to play the drum sounds. It isn’t clear if these are synthesized or in the event that they’re samples, however the latter appears probably. A TTP229 IC handles the capacitive contact sensing.
Lastly, some extra printed graphics on the reverse aspect present details about Antonovich, together with a QR code linking to his LinkedIn web page.
That is actually much more costly than a paper enterprise card. However when handed out thoughtfully, one in all these may improve the probabilities of being remembered and touchdown a contract.
