Dreaming of having a MIDI controller but you cannot afford to buy it? Why bother buying it as you can DIY? It’s easy to set up a MIDI controller. Before you start the project, you need to have these components: Scavenged Cirque Glidepoint resistive touchpad (must PS/2 compatible) 2X8 LCD must in 4-bit mode Two buttons (Assorted colors) A serial of Arduino board. Ok, there we go. You need to make sure all of the components in a fine condition; any broken parts will failed this project for sure.
Try to imagine, you’re having a good time, crunching a bucket of popcorn on your cozy couch with your favorite Saturday night show… I bet you didn’t even try to get off from your couch, no matter who is calling you. However, you’re still need to check who is on the Skype/MSN. Is there any good solution for this matter?
You love to play remote control toys? If you did, then this mikrokopter is what you’re been searching all the time… This mikrokopter is simply a cool and fun to play gadget. That of the awesome features includes: Audio Voltage Output to track the batteries availability. Multiple graphs drawers to check the sensor always working in a proper condition. Built-in MotorTest and watch the DebugValues with MK-Tools. Measure connection times and read the settings. Initial the proxy function View the RC-Data and much more. Currently, those cell phones that compatible with mikrokopter are: Nokia: 5XXX series, 6XXX series, 7XXX series, 9XXX series, EXX series and N series. Sony-Ericsson: K series and W series (also with M, P, S and T series as well) By the way, you need to make sure that your cell phone is support with Bluetooth API and MIDP 2.0, as this Microkopter only well functioned in the Bluetooth modul. Bon voyage.
If you are just starting in electronics this nice tutorial may save you tons of time. Yourtronics prepared a nice tutorial on how to make good quality PCB by using Photo Etching Method where board image is transferred during UV exposure. For this you will need an Ink-Jet printer for printing mask on transparent film, UV exposure box which can be made at home, several chemicals (Developer, Ferric Chloride, and Acetone).
Ultraviolet PCB exposure has to be performed very exactly. Quality may differ even if you under expose or over expose lets say 5 or 10 seconds. So it is better to rely counting to hardware timer that human. This dark room timer has all features needed to control any PCB exposure box or other devices if needed. Practically it is universal timer which can control lamps, heaters etc. because it uses a switching relay.
