embedded by Embedded Video YouTube Direkt Why build a DIY Segway? The main reason that I wanted to build a DIY Segway was simply because I wanted to see if it was possible. I also liked the idea of building something that strongly interacts with humans. I will now describe how I built it. Hardware
The Segway may not have set city trails ablaze, they have sparked plenty of DIY versions . A Segway is a costly transportation method since they cost as much as an entry level car. So, if you are tempted to build one of your own, follow this DIY Segway project and build one for a little over $400. The motors, wheels, chain, gears and batteries were sourced from cheap electronic scooters. The electronics behind the DIY Segway are all custom.
We’ve seen plenty of guitar hero projects and even a laser harp hero , but now we have a football hero (Soccer for us Americans).Â Made for the music industry, the director pulled together a team of DIYers and football players to make the game a reality.Â Using some piezo sensors to detect impact vibrations using the Arduino , he projected the game on a warehouse wall to play. More details on the project’s background can be found in this video .Â Not too much detail of the project such as source code is available, but setting up piezo’s with an Arduino is pretty straightforward .Â Check out some of our other Arduino projects below: <p style="text-align:right;color:#A8A8A8"></p>
Slide the battery holder into the PCB ( but do not solder it in ). Make sure that the battery is aligned correctly. Putting in the battery backwards shouldn't damage the circuit but its still not a good idea so try to get it right the first time. The back of the PCB has a silkscreen to help determine which way the battery goes in.
An Arduino Compatible Wearable Electronics Platform For the last few years Ladyada has been thinking about everything she wanted in a wearable electronics platform for Adafruit's community of makers, hackers, crafters, artists, designers and engineers. After numerous prototypes, we finally have what we think is the perfect platform.
Drawdio is an Interaction Design project by Jay Silver, which augments a conventional graphite pencil, and in turn creates a musical instrument which is controlled through the stroke and gesture of the performers hands. Drawdio makes use of a graphite pencil, a 555 Timer, a couple of capacitors and resistors, a speaker and battery.

Ciao a tutti ragazzi. Dopo l'algoritmo E.R.E.R. ci siamo dedicati principalmente a semplificare il sistema di funzionamento del nostro sensore per permettere anche agli utenti meno esperti di costruire il proprio senza troppi problemi. Come di certo ricorderete il sensore di prossimità LED che ho progettato tempo fa necessitava di due resistenze e quindi vari collegamenti. Per facilitare il montaggio e rendere veloce e semplice il test ho ripensato il circuito in modo da non necessitare di altro che di due LED infrarossi da 850nm. Incredibile il range raggiungibile con tempi di esposizione alti. Con una lettura di durata 115 millisecondi è possibile percepire un foglio A4 in cartoncino nero opaco a piu' di 150cm !
Olá pessoal. Hoje vou mostrar como criar uma rápida agenda em Python usando banco de dados MySQL. Ao final desse tutorial voce terá aprendido:
Aqui usamos um elemento Piezo elétrico para detectar som, o que nos permite usá-lo como um sensor de golpes. Usamos a vantagem da capacidade do processadores para ler sinais analógicos através dos conversores analógico-digitais (ADC). Estes conversores fazem a leitura da voltagem e a transformam em um valor digitalmente codificado. Neste caso as placas Arduino transformam a voltagem para um valor entre 0 e 1024. 0 representa 0 volt enquanto que 1024 representam 5 volts na entrada de um dos 6 pinos analógicos.
How about we just show each other our privates and call it a Skype? Seen here reaching previously unknown levels of sadness, a user demos Kajimoto Laboratory's Kiss Transmission Device. The devices were designed to simulate the kiss of a lover (or webcam stripper!) across the internet by connecting two people with a box of rotating electronics in their mouth. Mmmmmmmm . NOW CHOKE ME WITH YOUR TONGUE.
Holy shit, it's a PVC pipe bomb! No, not really. It's the Knock Lock, a homebrew door lock that will only release the deadbolt if you perform the secret knock. Cooooool -- I want one for my clubhouse! A microphone (okay, really a speaker) presses against the door and listens for knocks. If it hears the right number of knocks in the right cadence it triggers the motor to turn the deadbolt and unlock the door.
Cry Wall is a secret-keeper wall for people to express their feelings. In the society right now, people are competitive; it is hard to build a strong trust in between each person. You need to make sure who you are talking to and what you are talking about when you have conversation with others. There most be some time you want to talk to someone about how you feel deeply in your heart, but you don’t really have that person to talk to. Cry Wall is built to be the “Listener” and the “Royal Keeper.” If you have something want to say but cannot or don’t want to tell other people, you can come to cry wall and tell him.
