3D Printed Car

3D Printed Car

 

Printing this car took just 44 hours our out of 44 parts. Just bolt on some electronics and wheels are you are ready to drive! Love the design but up close it doesn’t look polished like a metal vehicle but you can see that it goes together in thick levels. What will we see in the future? Instead of customizing your new car by picking a color, interior trim option and accessories are we going to be able to push and pull some of the body features? It sure does open things up for some interesting thoughts.

DIY Clothespin Piano for the iPad

DIY Clothespin Piano for the iPad

 

 This DIY Clothespin Piano is a fun project by from fiddlewax that will give you small physical piano keys to let you play songs on your iPad without tapping the screen with your fingers.

“Touchscreens are great, but when it comes to playing music on them, the lack of physical keys can be a drag. So I decided to round up some household stuff and make a piano keyboard that tricks the iPad into thinking it’s being played by your fingers (with the help of some clothespins and aluminum foil)! It’s quite easy to make a capacitive piano interface, and all told it cost me less than $5. All you need is some wooden clothespins, foil, markers, tape, rubber bands, stiff cardboard, and some patience to cut and piece it all together.”

Smart Mailbox Project

Smart Mailbox Project

 

If you have a mailbox outside your house you might have to look at it many times to check to see if your mail flag is up. Of course this isn’t a very efficient use of your time. Wouldn’t it be great if there was some type of visual indicator in your house that would alert you when the mail has arrived? Wait no longer, Bob from Galactic Studios has built a Smart Mailbox Project that will come to your rescue. He provides all of the build details so you can also build your own. It uses a 16F1825 PIC microcontroller and a reed switches and an IR beam to monitor when the door is open, when there is mail in the box and when the flag is up. Bob shares some of the learning events that he had along the way that lead to some modifications.

I think the next version needs to add more sensors! What about a weight sensor so Bob can know how much mail he has, it could even guess that a weight over a certain preset is a package. I am also thinking with our connected life you need to get some kind of notification on your smart phone that a mail event has occurred. :)

Thanks for the tip Jim.

“When the mailman comes and delivers my mail, a toy mailbox inside the house raises its flag. When I go out to retrieve my mail the toy mailbox lowers its flag. If I go out again to put outgoing mail in the mailbox, the toy mailbox is smart enough to know not to raise its flag. If anything goes wrong, like the mailbox door is left open or the battery is low, the toy mailbox waves its flag as a distress signal.”

EWaste 3DPrinter

 

If you think the price of 3D printers is hitting the floor check out what built for $60. About 80% of this EWaste 3DPrinter is recycled computer parts which is abundant and readily available.

“First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small plastic extruder and give an overview on plastic extrusion calibration, driver power tuning and other few operations that will bring the printer to life. Following this instructions you will get a small footprint 3D Printer that is built with about an 80% of recycled components, which gives it a great potential and helps to reduce the cost significantly.”

How Vacuum Tubes Work and How they are Made

at 1:51 pm. Filed under Educational

 

With the reliability of modern electronics vacuum tube making is a dying art. Here are some great videos demonstrating the laborious steps that go into creating them.

“Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all electron tubes contain vacuum: gas-filled tubes are devices that rely on the properties of a discharge through an ionized gas.”

DIY Small Bench Power Supply

DIY Small Bench Power Supply

 

This project by is a nice DIY Small Bench Power Supply. I like the case design which is lettered with the toner transfer method. Great looking results.

“The heart of the unit is basically the same as on the other power supply. It is based on the LM2596S. This IC can handle up to 3A with a good heat sink. I would use it only for 2A to be on the safe side.”
