Making of a New Nixie Tube

at 8:46 pm. Filed under Complex Hacks, DIY Hacks


A Nixie Tube is an old piece of technology, Dalibor Farný has resurrected the old technology by working through the techniques to build new tubes by hand. The video shows the tedious process of the low volume creation of them. Lots of complex mechanical steps are needed from spot welding to glass blowing is needed.

“The nixie tube is a vintage display device which had been used until 70s when it was replaced with LED displays. The complex knowledge of manufacture of nixie tubes literally died with tube factory’s engineers, glassblowers and machine operators.
I discovered nixie tubes in 2011 and since then, I’ve devoted all my time to studies of nixie tubes and its manufacturing processes. After years of intensive work, with help of many people, I eventually succeeded and have revived the knowledge and equipment for production of nixie tubes.”

Food Robots

at 7:16 pm. Filed under Complex Hacks

 

We have seen some food robots before. Looks like we might be on the verge where the robots are going to be used for what they are good for such as show in the video where the robot spreads pizza sauce perfectly or can finally pick apples as good as a human. Just as in any industry when simple tasks such as flipping a burger is automated some of these jobs will be replaced. However fewer high tech jobs will replace the simple jobs since the robotic systems will now need to be installed, repaired and monitored. How long will it be before gas stations and fast food restaurant have no onsite employees. I think it could be soon!

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.”

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.
