Have engineers stopped putting Easter eggs into technology lately? It’s always been a fun way to connect with your more advanced customer base (i.e. hackers) — anyway, here’s a great Easter egg you can find on the Hewlett Packard 54600B Oscilloscop — Tetris!
[RaffttaM] discovered this trick when a coworker let him know that one of the oscilloscopes in the lab had the hidden feature. A little fiddling later and a game of Tetris was revealed. If you press the Print/Utility button on the 54600B oscilloscope, followed by pressing the second and third button below the screen at the same time, you can launch the game!
Another cool embedded Easter egg is in the Game Boy Printer — If you hold the feed button during power up it spits out a Mario themed image! One of our readers even managed to hack the printer to show the Hack a Day Logo instead!
Do you know of any more modern tech with cool (and sneaky!) Easter eggs? Let us know by sending in a tip!
We had a blast with the Trinket Contest in October and November and can’t wait to see what you can come up with for this month’s competition. Microchip Technology is one of our advertisers and they offered us 20 Fubarino SD boards to give away as prizes. The challenge for you is to add our URL as an Easter Egg in your own microcontroller project. Rise to the top of our seemingly arbitrary system for picking winners and one will be delivered to your door for your future hacking pleasure.
Obviously we mean http://hackaday.com when we say URL, but what constitutes an Easter Egg? We figure it’s anything that is not apparently obvious in a piece of hardware. We built a quick example to get you thinking. Shown off in the clip after the break is a clock that displays our web address every day at 1:37pm. What did we pick that time? Because our clock displays in 24-hour time format and 13:37 is leet. See the code we used in our repo.
We thought of a few others, like making an embedded gaming that uses the Konami Code to reveal the Easter Egg, or a man-in-the-middle device that attaches to your keyboard and redirects your feeble attempts to load Facebook by closing the tab and opening Hackaday. The sky’s the limit with how creative these things can be!
Follow these rules to submit your qualifying entry:
- You must somehow hide http://hackaday.com in your microcontroller project (embedded Linux doesn’t count unless you do some type of bare-metal programming)
- Preference will be given to projects that are both clever and well documented. Notice we made a video, and posted code and an explanation of our project.
- Write an email that has “[Fubarino]” in the title, includes the information on your documented entry, and lists your name and mailing address. Your name and mailing address will be used for shipping only and NOT for anything else. Emails should be sent to: email@example.com
- Entries must be received before 12:00am Pacific time on 12/19/2013.
- Employees and their families of Hackaday, SupplyFrame, and Microchip Technology are not eligible to win.
What are you waiting for? Dust off those chips and get hacking!

The picture you see above is taken from the ROM of a Macintosh SE made in the late 1980s. This black and white image remained buried inside old Macs until [Adam] and [Trammell] at NYC Resistor reverse engineered these old Mac ROMs and found a few really cool Easter eggs.
[Adam] and [Trammell] have been dumping ROMs from old computers for a while now. Their modus operandi is finding old 27C-series EPROMs on old computers, prying the out of their comfortable home, slapping them in a breadboard, and wiring up an Arduino clone to dump the data to a computer.
Recently, the guys found an old Mac SE lying on the side of a road in Brooklyn and brought it over to NYC Resistor. They had known about images hidden in the SE ROM, but the guys wanted to know how and where these pictures were stored. After carefully inspecting the binary file generated from dumping the ROM, [Adam] was able to recover three images hidden in every Macintosh SE.
The folks at Apple – especially in the heady days of the Apple II and 68k Macs – hid quite a few Easter eggs in the ROMs of their computers. For instance, the Apple IIgs has audio data stored in the ROM, and the Macintosh Classic hid an entire operating system – System 6.0.3 – in the ROM of the machine.
