However, they will only be able to tell the time in five-minute increments. Mathematical geeks will however be able to tell the time as they work it out by knowing the numeric values of different colours and adding up the correct squares. Fibonacci ClockĬost: $135 Only true geeks could appreciate this dynamic, Mondrian-style sculpture present, which hasn’t really been created with the intention of telling the time for us ordinary folk. This little guy can be controlled from your smartphone, and you’ll have hours of fun maneuvering him around your house, as long as you can fork out the required $200 to buy him. Sphero “Star Wars” BB-8 App-Controlled RobotĬost: $199 Star Wars devotees will be particularly excited about this product: it’s a BB-8 droid that proved to be so popular in the latest movie, Star Wars: The Force Awakens. However, they can only charge, and can’t handle data transfer for syncing. These devices are available in gold, silver, black and rose, and are equipped with standard USB-A connector on one end and MicroUSB, Lightning, and USB-C connectors on the other end. You’ll also be able to ensure that your guests can always charge their device, no matter what device they have. Rather than getting frustrated with a tangle of cables, try out this singular, multi-USB cable that will offer so much more convenience and simplicity. Green is minutes, red is hours, and purple counts as both minutes AND hours. Chafon multi-USB CableĬost: $8.99 .uk With all the high-tech devices that we carry around these days, it seems that we can never HAVE enough USB cables on hand. Adafruit explain a little more about how the clock actually tells you the time. Just imagine being able to create an outdoor cinema while camping! This device supports both the Miracast and AirPlay protocols for wireless transmission and is compatible with Mac and iOS devices and many Windows and Android devices. 17 inches and 3.8 ounces, but it will allow you to project images and videos from your mobile device or computer screen onto any surface. If you know anyone that’s perhaps a bit geeky and really into awesome gadgets (including yourself), then these awesome gifts should sort them out in no time at all: iCodis CB-100W Mobile ProjectorĬost: $199 The handicap of being on the road is no longer a barrier to your tech entertainment thanks to this small and lightweight pico mobile projector. While you scratch your head and scour online and in the shops for the perfect festive gift, we thought we’d help you out a bit. The recursive approach involves defining a function which calls itself to calculate the next number in the So the festive season is in full swing and you’re already starting to scramble for presents that will satisfy the particularities of your loved ones and friends. The iterative approach depends on a while loop to calculate the next numbers in the sequence. The Fibonacci Sequence can be generated using either an iterative or recursive approach. This clock comes with a 10 year guarantee and a leaflet with Fibonacci and the Golden Ratio explained in the leaflet. What’s more, we only have to initialize one variable for this program to work our iterative example required us to initialize four variables. ![]() This code uses substantially fewer lines than our iterative example. The recursive approach is usually preferred over the iterative approach because it is easier to understand. We have defined a recursive function which calls itself to calculate the next number in the sequence. The difference is in the approach we have used. The output from this code is the same as our earlier example. ![]() ![]() This loop calls the calculate_number() method to calculate the next number in the sequence. In other words, our loop will execute 9 times. This loop will execute a number of times equal to the value of terms_to_calculate. Let’s begin by setting a few initial values: This is why the approach is called iterative. Each time the while loop runs, our code iterates. This approach uses a “ while” loop which calculates the next number in the list until a particular condition is met. Let’s start by talking about the iterative approach to implementing the Fibonacci series. Python Fibonacci Sequence: Iterative Approach ![]() The rule for calculating the next number in the sequence is: It keeps going forever until you stop calculating new numbers. Each number is the product of the previous two numbers in the sequence. The Fibonacci Sequence is a series of numbers. We’ll look at two approaches you can use to implement the Fibonacci Sequence: iterative and recursive. In this guide, we’re going to talk about how to code the Fibonacci Sequence in Python.
