It was from self study during a previous work term, we definitely don’t learn about digital logic and semiconductors till upper year.

This guy has the idea!

Source: It’s the same as my idea ; )

I would like to add that any Electrical Engineer that understands how a 555 timer works believes they are extremely neat!

555 timers *are* neat. They’ve got limited capabilities and the trick is to see how complex an output you can get. It’s relatively easy to think about doing blinkenlights with a microcontroller, if you have the infrastructure to program one, but even the simplest microcontroller is overkill for this. With the 555 timer, an electrical engineer ought to be able to look at the card and see exactly how the circuit works, rather than seeing a black box.

Also, this is a business card, not a resume. The whole point is to convey your contact info in something that won’t get thrown away immediately. I think this succeeds well.

Funny that the word generally comes from a calligraphed Xerox!

Sheldon called to say: He’d be embarrassed to be enrolled on a degree course whilst still carrying on like 555 timers are a neat idea. I mean does this dude actually want to get hired using this card, or is it more about inviting speculation as to whether he managed to pass the first year vs. “I bought some sh*t from Adafruit”…?

My pixelated heart lights up whenever I see the word ‘blinkenlights’. Thank you, Cory!

and yet, that’s quite a font fail.

A good friend of mine is working on a similar product that, he says, is slightly more advanced and aesthetically pleasing.

I wonder if he actually learned how to do this in school…

Look at the subtle coloring of those blinking LEDs, the tasteful thickness of the PCB. Oh my god, it even has a capacitor!

Dang, this would have been a perfect use of conductive inks!

3) Enjoy the light shoul

(It is pretty cool!)
