Interfacing Buzzer to Arduino

-
Piezo buzzers are used for making beeps alarms and tones. They can be used in alarm systems, for keypad feedback, or some games. Light weight, simple construction and low price make it usable in various applications like car/truck reversing indicator, computers, call bells etc. Also they are fun to ...

With the rising trend of automated restaurants where people literally have to interact with no one , comes the need to have technology and design back that scenario. Enter the Bellder, a tablet that takes care of everything for you from ordering, to notifying, to acting as a payment gateway. Each patron entering the restaurant gets handed a Bellder. Its design is sleek enough to seem appealing but bulky enough to not get stolen, or break (with rough usage). The Bellder acts as a menu card, allowing users to order food visually, looking at the dishes rather than just reading names. Once the order is placed, use the Bellder itself to pay for your meal by swiping or inserting your card inside it. I assume future iterations will include NFC payments that are on a high rise. Post payment, the Bellder acts as a notification unit, alerting you when your food’s ready so you can collect it from the kiosk. You exchange the Bellder for your food, having completed the restaurant experience witho...

Testing RNGs with PractRand

-

PractRand  is a random number generator test suite, somewhat like the DIEHARDER and NIST tests I’ve written about before, but more demanding. Rather than running to completion, it runs until it a test fails with an infinitesimally small  p -value. It runs all tests at a given sample size, then doubles the sample and runs the tests again. 32-bit generators LCG A while back I wrote about looking for an RNG that would fail the NIST test suite and being surprised that a simple LCG (linear congruential generator) did fairly well. PractRand, however, dismisses this generator with extreme prejudice: RNG_test using PractRand version 0.93 RNG = RNG_stdin32, seed = 0x4a992b2c test set = normal, folding = standard (32 bit) rng=RNG_stdin32, seed=0x4a992b2c length= 64 megabytes (2^26 bytes), time= 2.9 seconds Test Name Raw Processed Evaluation BCFN(2+0,13-3,T) R=+115128 p = 0 FAIL !!!!!!!!

Audible Badges Decoded!

-
Image
If you’re an audible listener, you know the little surge of joy that happens when you’re listening to an audiobook and suddenly there’s a notification that you’ve unlocked a new badge. But they’re mysterious little buggers and it’s hard to find a description for each badge. Until now! Below, I have outlined each badge and what it takes to get it. I’ll admit, I didn’t even know about Audible badges until someone mentioned them during the Book Riot Insiders Audiobooks chat. But as soon as I knew they existed, I wanted them all (well done, Audible marketing, well done). If you have an Audible account, you can see which badges you have by going to the “me” tab under “more” on the bottom of your Audible app. (I don’t think you mean see which badges you have viewing your Audible account on a regular web browser, I’m pretty sure you have to use the app, but I am sure someone will correct me in the comments if I’m wrong).  There are 15 total badges; within each category, you can obtain ...
