Nice trick. You can use a wider wooden block and attach 2 magnets to it. With 2 attachment points, it will completely remove any wobble at all...

This looks very realistic. Looks just like the one in the movies.

Thanks a lot for this instructable, using the IR_Reading.ino sketch provided and some others info form other website, I succesfully decode my Panasonic AC (without heater, for Indonesia market).I have to increase the number of pules pair in the sketch to 240, because it turns out my Panasonic AC use 216-bit protocol, for total around 220 pulse pairs, to be able to record the complete signal.
That is a great find. Using those ready-made boards certainly saves a lot of time and trouble in putting together the circuit, especially for beginners.
I thought the same thing! But diving in, it turned out to be so much cooler...

That's great insight. I agree with you that it's important to make profit to keep it self-sustainined.

The best ir tutorial i have found. Thank you so much! i only tested the raspberry part. But this is very great.P.S. there exists ir transmitter and ir receiver which already contain the transistors and resistors. For beginners i can recommend this ones.https://www.amazon.de/gp/product/B01FSY62UE/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

Pretty cool!You mention that fabric is better. The downside is you can't be sure what print you will be able to find. There is a way around it:Take a plain non-printed fabric, print any comic of your choosing on an iron-on sheet, iron it onto the fabric. Tada! You get the benefits of fabric with comic of your choice :)
Read up on RC circuits. They just use a capacitor and resistors. You won't get fade to on, but you can get a slow fade out with the simplest RC circuits.
These could give you some ideas:http://www.instructables.com/id/Things-to-do-with-...http://www.instructables.com/id/The-Makin-of-a-Cas...Search around and I'm sure you'll find tons more uses of old CPU cases.
The only inbuilt wireless technologies in your typical smartphones are Bluetooth and Wi-Fi. A wireless doorbell will probably use RF(Radio Frequency). So there cannot be a direct control. You can use an Arduino to control the wireless switch and connect your phone to the Arduino using Bluetooth or Wi-Fi to send commands.So you phone controls the arduino which in turn controls the wireless switch which in turn controls the wireless dorrbell...
Check if the connections are proper. Could be a fluctuating voltage level due to a loose connection. Also try covering the receiver to see if the random values stop(could be another source in the room).
Hey guys. I have some weird situation. Everything seems to be working fine but when I do mode2 -d /dev/lirc0 I get lots of vaues even though I'm not pressing any buttons on any remote. Do you have any idea why that happens?Thanks!
As you mentioned, you need 7W to light up a meter. So assuming you are using 30 LEDs per meter strip, each LED is consuming about 20mA(which is perfect!). This is important as you will need to know how many LEDs you can light up safely.To pull power for it, you mention you are considering soldering to USB's power terminals. You will be unable to use that USB port as a majority of the current will be going to the strip instead of the peripheral connected to USB. You'll be able to pull 500mA from it, but might be limited to only 100mA depending on your laptop(http://electronics.stackexchange.com/questions/549...) Also, you'll need a buck-booster as Yonatan24 mentionedConnecting to the laptop charger port, is a better option if it provides 12V. Light will only glow when charger is connected, but chances of anything going wrong with motherboard are greatly reduced.
It will be very difficult to remove a black background and make it white. The edges will have a slight gradient from black to the object color(off-white in your case) and removing the gradient will create very sharp edges and keeping it over a white background will cause blackness at the edges.You can use a black background by itself and it looks very good. A very good instructable on using black backgrounds: http://www.instructables.com/id/Photograph-a-Black...Whitish or transparent objects are always a bit tough to make visible, but it is certainly possible. You just need to play with the masking a bit. Shadows also play a very important role in bringing out the shape of a whitish object as you can see in this image, the breadboard is the same color as background but is visible due to the shadows: https://cdn.instructables.com/FUP/MNJI/HTEUJO6Y/FU...You can even have the shadow fall towards the camera to make it even more apparent, even though I warned not to bring shadow to front in step-4...
In the video, he does mention the handle broke into 3 pieces while sanding. So the fragility of the handle is quite apparent.
Hard does it hit? I'm tempted to just stand in front with a gaping mouth(and some eye protection). Very cool build!
Cool robot! Any inspiration from August Kekulé who discovered the Benzene structure in a dream of a snake eating its own tail and then whirling round and round?
Sounds and great, white background for image creat more value to it's user then other images before before backgrund removal, any photo replaced on white background catching eye greatfully, and when some one need to use their photos for e-commerce or web stor then it esential for making background white, I have attached some white background photos, to see more white background photo please visit my photo cutout onto white background portfolio: http://www.portfolio.clippingcrowd.com/
