When you need a Waveform Generator but just have a Record Player the obvious solution is to create a Waveform Generator Record Player.  This creation uses a 3D printed head for the record player arm and has some simple optics mounted. Similar optics that would be used in a line following car feedback the pattern. Swapping the disk changes the pattern.

“The light sensor is a 3 mm Everlight ALS-PT204-6C/L177. It was chosen because it responds to standard visible light, rather than infrared. I want it to see what I see.

The light sensor connects to +5VDC and to the middle pin of trimpot R3 (100 kΩ). My trimpot was dialed to about 20 kΩ, but you’ll need to adjust it based on the light conditions and distance to the target. The goal is to create as large of a signal as possible, with a compromise between flattening the top of the wave and the bottom of the wave.”

DIY Flexible Circuit Board

 

DIY PCBs are quite simple to make these days but DIY Flexible Circuit Boards are still something that is not easy and also not common in most PCB production houses. With this technique you can now dabble with flexible boards in your next project.

Thanks to Wheedal for the tip

 

“A fairly new elastomeric rubber filament is now available that sticks quite well to copper. It is called Ninjaflex. In fact, it sticks quite well to almost anything including acrylic, blue painters tape, and glass.

A circuit board pattern can be drawn in a free program like 123D Design and then extruded to a thin thickness and saved as an STL file. It can then be printed on top of a thin copper clad board or plated conductive fabric: step 1 pic. It can then be etched in the standard way with a Ferric Chloride solution.”

The Tesla Gigafactory is still being built. It is huge but the building will be much larger when completed. Tesla and Panasonic are in a joint venture in this building. Full production is slated for 2018. Full production will be 500,000 to 1,500,000 packs per year! Automated battery construction for the win.

Keep your fingers clear of these machines! If you are looking for a job that is bound to eventually take off one of your fingers some of these machines are sure to help with that. Fantastic machines but most are very dangerous.

DIY Circular StepperMotor Clock 

 
Looking for a clock build? This DIY Circular Stepper Motor Clock looks like fun and the parts would be very inexpensive.
 
“The idea behind the clock is a circle with a circumference of 72cm (28.3465 inch’s) that ticks at 1cm every ten minutes which means every 72 ticks will equal 12 hours making it a 12 hour clock. ”

SwagBot is Herding Australian Cattle

SwagBot is Herding Australian Cattle

 

Automating crop harvesting is one farming duty that robotics is good at but dealing with animals that are lose in a field is another story. The SwagBot is a robot that will soon be tending to the animals in the field.

Via: IEEE Spectrum

“SwagBot is designed to “work in highly undulating terrain, for the purposes of supporting farmers in grazing livestock operations,” Dr. Sukkarieh told us. The robot is electric, with a rugged waterproof chassis that can deal with almost anything Australia can throw at it. It’s not autonomous yet; it just uses vision right now to see the animals, but the researchers are working on figuring out what kinds of sensing systems they’ll need to do a variety of different activities.”

Monoprice MP Mini 3D Printer

 

This might be the time to jump onto the 3D printer bandwagon. The place that provides cheap good quality cables looks to now be the place to pick up a cheap and reliable 3D printer. At $200 it has some features that you wouldn’t expect to see such as a nice full color display to view settings such as platform temperature so you can easily keep your eye on the status. Looking for a review, Hackaday did a good one.

 

“Features

  • Heated aluminum build plate nozzle cooling fan for printing all filament types
  • Fully assembled and factory calibrated so you can start printing right away
  • Complete kit with sample PLA filament, bed scraper, and MicroSD™ card with preloaded model files
  • Micro USB and MicroSD card connectivity
  • PC and Mac® compatible
  • Compatible with Cura, Repetier, and other software”
