Adafruit PCB Manufacturing Line

at 6:22 pm. Filed under Educational, Electronic Hacks

 

The Adafruit PCB Manufacturing Line is quite impressive. Ladyada (Limore Fried) goes through the entire process start to finish describing what each piece in the line does. Questions from the MIT students at the end are interesting also.

“Ladyada is the hacker @ Adafruit, founded in 2005 by MIT hacker & engineer Limor “Ladyada” Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Adafruit has grown to over 100+ employees in the heart of NYC with a 50,000+ sq ft. factory. Adafruit has expanded offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store.”

iPhone Headphone Jack Hacked back into an iPhone 7

at 6:04 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

Scotty from Strange Parts known for building his own iPhone has been busy with another iPhone project. As most people know the Apple iPhone got rid of the headphone jack and even though many people hate that decision it looks like Apple will not be bringing it back. After 4 months of designing and Scotty was finally able to replicate the functionality of the normal headphone jack functionality. Of course this would be possible to be done anywhere but being in the heart of the electronic marketplace in China sure helps. For example he was able to get things like flex PCBs made by walking over to the local PCB sales booth. See the video below for an interview Serpentza did with Scotty.

Safe Cracking Robot

at 10:34 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

We have seen safe cracking robots before but they never get old. The guys at Spark Fun made a great one. It would be funny to  see a CCTV video of a vault heist that uses some technology like this. The safe cracker could setup his rig and read a magazine while the technology did the hard work.

“Nathan Seidle’s wife gave him this already locked safe as a gift with no combination. Weird present, but he loves a good challenge. So he built a safecracking robot.”

Infrared Transmitter Arduino Home Automation

at 7:37 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Upgrdman shows us how to make an Infrared Transmitter Arduino Home Automation system. This system uses a very high power wide range IR LED so that it would be great to be placed in the general area of the equipment you would like to control. If you are interested in making your own the example code is provided.

“In this video I show an easy and low-cost way to do some home automation. I setup an Arduino with an infrared receiver and transmitter, then use it to control my television and a tower fan. This setup can be used to control pretty much anything that has an infrared remote, even air conditioners.”

ClearWalker – Polycarbonate Walking Robot

at 9:52 am. Filed under DIY Hacks, Electronic Hacks

 

Jeremy Cook built this walking robot  using a bunch of custom cut Polycarbonate for legs and gears. The brain is Arduino based and GoPro camera in the head. The motors are controlled via a few off the shelf H-Bridge modules. Controlling the robot is done via bluetooth.  Lots of time and thought went into this robot creation and it shows. It looks great walking around the beach .

Talking Multimeter Project

at 8:53 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

Rachel Dipirro and Jonathan Lo made an interesting Talking Multimeter Project for their Cornell University ECE 4760 Final Project. The multimeter is built around a PIC32MX250F128B. This is not a robust product that will be replacing your desktop multimeter since the range is not that great. For example it can just read resistance between 0 and 50K and voltage up to 10 volts. This range is fine for lots of work and the measurement front end could easily be swapped out with a high resolution ADC to greatly enhance this.

The multicolor LCD display is a great way to display the output and the number pad is perfect to control the system but of course the heart of this project is the voice output. The speech synthesis is performed by transmitting data to an external Microchip MCP4822 SPI DAC, the samples that are played are 16kHz samples that were compressed and stored onto system flash.

3D POV Display

at 10:45 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

There are lots of POV displays out there, lots have multi color LEDs that can display some impressive images. has built this  3D POV Display that has lots of tech going on. The addressable LEDs are setup in strips of varying heights. When spun this allows the display to create 3D images in color. A Parallax Propeller microcontroller powers the main display while an Arduino Pro Mini works with the ESC to keep things turning properly. To get power to the spinning portion of the board a wireless power module is used, this module can get about 10 watts of power through the air gap which is plenty for the LEDs.
