Pan / tilt base

As some of you alredy saw im trying to make a Wired pan and tilt base....but im a bit a novice in all this.... MayB someone have plan or can make an instructables (or mayB there already an instructable on it and i didnt see it) on how to make a Wired pan / tilt base that would support the weight of a standart mini Dv Camcorder( not because im using a camcorder is just the same weight :P) and that would turn slowly thxKoax

How to tilt a bed / linear actuators?

I'm thinking about making an alarm clock that literally gets me out of bed! The alarm clock would start tilting the bed to one side, untill i either get out of bed, or fall out of bed :) I was thinking of using linear actuators on one side of the bed to do the tilting. Does anyone here have any experience with linear actuators? How strong are they, and where can I buy them cheaply? Any other ideas on how to tilt a bed? Cheers - Chr

tilt sensor controlled by wireless remote

Hi: I would love to make a tilt sensor that can be placed inside something of value (since I'm a musician this happens to be a guitar case:), so that if someone picks up the guitar case, it would activate a loud alarm. It's easy enough to come up with a design for a tilt switch (maybe a ball bearing inside a tube), but it would be really nice if I could arm the circuit with a wireless remote. Any suggestions? thanks

Some help with camera tilt/rotating?

I am trying to make my own Pan and tilt timelapse device, to use with my camera (such as an Emotimo TB3). I want the design to be pretty feasible, but I want this to be fairly professional (in case I can market the idea.... idk about that but maybe I might be able to at some point). The problem with my design is that I want it to be pretty small and lightweight, so having the camera mount above the head seems like a good idea - (like this) However-that takes the camera away from the axis of rotation, increasing the strain on the motor (not a huge problem), but my main concern is that having the camera rotate off-center from the axis would cause issues, say, if the rig was used for gigapixel photography.  The other option is to mount the camera in line with the axis of rotation, but that causes a much larger design (which would look somewhat like this) So from someone who knows more about cameras than I, If I took a camera and used it in gigapixel photography (which would be the rigs second use), would having the camera rotate out of axis create problems in stitching, etc??

attiny85 tilt switch dc motor

Hello my project consists of an attiny85 with an led a dc motor a tilt switch and  a button. the button changes the pwm values and the led goes to the same values to know the strength of pwm.  the tilt switch will activate the dc motor at the corresponding pwm speed based on how many times the button is pressed. here is my code const int inPin = 3;         // tilt switch or button to trigger dc motor const int outPin = 1;       // dc motor const int buttonPin = 2; //button to change pwm const int ledPin = 0; // led to know the state of pwm int pwmvalue = 255; int buttonPushCounter = 0; int buttonState = 0; int lastButtonState =0; int LEDstate = HIGH;      // the current state of the output pin int reading;           // the current reading from the input pin int previous = LOW;    // the previous reading from the input pin // the follow variables are long's because the time, measured in miliseconds, // will quickly become a bigger number than can be stored in an int. long time = 0;         // the last time the output pin was toggled long debounce = 50;   // the debounce time, increase if the output flickers void setup() {   pinMode(buttonPin, INPUT);   pinMode(ledPin, OUTPUT);   pinMode(inPin, INPUT);   digitalWrite(inPin, HIGH);   // turn on the built in pull-up resistor   pinMode(outPin, OUTPUT); } void loop() { buttonState = digitalRead(buttonPin); if (buttonPushCounter == 1) {   (pwmvalue == 255);}   if (buttonPushCounter == 2) {   (pwmvalue == 180);}   if (buttonPushCounter == 3) {   (pwmvalue == 110);}   if (buttonPushCounter == 4) {   (pwmvalue == 70);}   // compare the buttonState to its previous state   if (buttonState != lastButtonState) {     // if the state has changed, increment the counter     if (buttonState == HIGH) {       // if the current state is HIGH then the button       // wend from off to on:       buttonPushCounter++;           } else {       // if the current state is LOW then the button       // wend from on to off:           }     // Delay a little bit to avoid bouncing     delay(50);   }   // save the current state as the last state,   //for next time through the loop   lastButtonState = buttonState;   // turns on the LED every four button pushes by   // checking the modulo of the button push counter.   // the modulo function gives you the remainder of   // the division of two numbers:   if (buttonPushCounter % 0 == 0) {     analogWrite(ledPin,pwmvalue);   }   if (buttonPushCounter % 1 == 0) {       analogWrite(ledPin,pwmvalue);   }   if (buttonPushCounter % 2 == 0) {       analogWrite(ledPin,pwmvalue);   }   if (buttonPushCounter % 3 == 0) {       analogWrite(ledPin,pwmvalue);   }       int switchstate;   reading = digitalRead(inPin);   // If the switch changed, due to bounce or pressing...   if (reading != previous) {     // reset the debouncing timer     time = millis();   }   if ((millis() - time) > debounce) {      // whatever the switch is at, its been there for a long time      // so lets settle on it!      switchstate = reading;      // Now invert the output on the pin13 LED     if (switchstate == HIGH)       LEDstate = LOW;     else       LEDstate = HIGH;   } LEDstate = HIGH == pwmvalue;     digitalWrite(outPin, pwmvalue);   // Save the last reading so we keep a running tally   previous = reading;   } is my code written correctly for my purpose is there anything i could have written better? its compiling without any problems andni havn't been able to upload because i ust back into arduino and im waiting for my attinys to come in. thank you guys for reading.

Advice for a simple bluetooth and tilt sensor device.

Hi! I'm new to electronics and want to create my own simple Bluetooth device. Basically I want to create a device with a screen that I can control using an app on a phone.  I'm planning on using a 3-axis accelerometer too, just to learn more about how those work and play around with some tilt options.  I'm working with a friend that is an EE student, but we still need some advice to get started. Basically I want to use a phone app to update photos or videos displayed on the device.  Also, I'd like to create a small program where I can tilt the device and move a ball on the screen.  Right now I know I need a Bluetooth module, a screen, and a 3-axis accelerometer but I have no clue which kind (there are so many choices! especially for the Bluetooth modules!).  We have somebody that will do the programming for us, so we just need some direction as far as the electronics go. Also, should I use something like adruino, or should we look for more experienced engineers to design it for us.  We'd rather learn how to do it ourselves though, and we don't have enough money to pay for a professional. Any advice would be greatly appreciated!  I'm starting to get very interested in electronics as a hobby, and would love to learn how to start doing these things! Regards, Patrick

accelerometer based mouse, what happens when tilted

I got a free dual axis low g accelerometer from freescale, the output voltage is proportional to the g forces, I also have a ton of free PICmicro chips with I2C and A/D converters. I want to make a mouse just basically for proof of concept. I was thinking about how to program it, since I want to tell the computer the "movement since last request", I would need to calculate the speed using the g force reading (9.8m/s2 = 1g)if the mouse is moving at a constant speed, the g force would be 0, and the speed would be the same as the last reading, also, gravity affects the reading if the mouse is tilted slightly, increasing the speed even if it is not moving at all, so I was thinking, if the mouse was tilted, and then balanced again, the speed would remain the same, causing annoyance to the user. this is the problem i would like to solve.Is there a space efficient way to make a accelerometer not affected by tilt? if not, is there any tricks I can use (such as detecting unusually uniform g force and automatically go into "joystick mode")? I have been thinking about using a thumb button to zero the speed (while held down, the mouse can also do "super precise mode" which means one pixel per half second no mater how fast), is the thumb button the way to go? how about sensor to see if there is contact with a surface? or four IR rangers to detect tilt while above a surface?side note: does anybody have a datasheet for ata1060xa? its a optical mouse sensor with built in 27mhz RF transmitter made by @lab, and they don't share datasheets.oh and head on over to cypress for free wireless usb modules (2.4ghz i think, multiple channels) if you are interested in cheap RF, i have two with 50 meter rangeinfo on mouses and keyboard serial interface found here

Brushed DC motor HP requirements for Longboard? Answered

So I have 2 brand new tilt/trim pump motors and thought about making a set of matching electric longboards since products like Boosted Boards seem to have become fairly popular.  I am not too sure whether the tilt/trim motor would be strong enough though, they are a decent size motor though.  But it got me thinking what size is required for an electric longboard? The main problem with the tilt/trim pump motors is that I can't find specs on them anywhere, just specs for tilt/trim pump assemblies they are off of, but nothing about the motor itself other then SAE J1171 Marine rating.  Because of this I thought of buying another DC motor to do the job.  (Picture of tilt/trim motor) The constraints for me is that I have a couple 12 - 24v 100A motor controllers already, for brushed motors only.  As well, I want to just pick up a couple cheap $40 12v, 24AH Sealed led-acid (SLA) batteries from the local Ace Hardware and run either a 12v or 24v motor.   Options on eBay for affordability purposes range from 12v, 24v, 90v and 180v dc, obviously 90v and 180v are out of the question.  Looking through the 12vdc and 24vdc motors, there are many fractional HP motors available.  I was looking at something like this;;=STRK%3AMEBIDX%3AIT Running 1/4 HP at 24v, would 1/4HP be enough though?  I know electric motors HP ratings are lower then petrol engines, a 6.5HP petrol go kart runs about the same as an identical kart with a 1HP electric motor. If that isn't enough I am thinking a 2/3HP motor from Holley might be better?;=STRK%3AMEBIDX%3AIT Wondering if someone has an idea for sizing.  I know lots of eBikes and Chinese electric mini bikes and things have 500W motors, so roughly 2/3HP, so I can't imagine I need more then that.  As well I don't want it to go too fast (fear of speed wobbles) but if anyone would have an idea of sizing that would be super helpful!

A souvenir vendor took two digital pictures of me and my husband, merged them on a computer, printed the interleaved (?) image, then adhered a piece of acrylic with vertical lines (scratches?) to it.  The result is like a hologram in that you see the two different images as you tilt the (acrylic overlaid) photo. How can I make those?
