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!

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.

PID Controller Theory

at 11:07 pm. Filed under Educational


 
 

Dave 2 over at the EEVBlog explains how PID works. Wikipedia also has some great info.

 
 

“A proportional–integral–derivative controller (PID controller or three term controller) is a control loop feedback mechanism widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value {\displaystyle e(t)} e(t) as the difference between a desired setpoint and a measured process variable and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D respectively) which give their name to the controller.

In practical terms it automatically applies accurate and responsive correction to a control function. An everyday example is the cruise control on a road vehicle; where external influences such as gradients would cause speed changes, and the driver has the ability to alter the desired set speed. The PID algorithm restores the actual speed to the desired speed in the optimum way, without delay or overshoot, by controlling the power output of the vehicle’s engine.

The first theoretical analysis and practical application was in the field of automatic steering systems for ships, developed from the early 1920s onwards. It was then utilised for automatic process control in manufacturing industry, where it was widely implemented in pneumatic, and then electronic, controllers. Today there is universal use of the PID concept in applications requiring accurate and optimised automatic control.”

DIY LIPO Battery Spot Welding

at 11:19 pm. Filed under Crazy Hacks, DIY Hacks

 

WeAreTheWatt is building a DIY LIPO Battery Spot Welding project. The construction is very nice. The PCB is very well laid out but of course even with a very heavy copper clad board it would not be able to handle the amount of current he needs. Heavy bus bars are used to pass the current through the fuse and across the switching transistors. There is a foot pedal activation method or a neat self detection method which watches for the leads being pressed against the thing to be welded and then passes the desired amount of energy.

Laptop Hacked into a Cool Desktop PC

at 11:11 pm. Filed under Computer Hacks

 

 

DIY Perks hacked an old damaged laptop into a great looking desktop PC. The PC used has a damaged screen and was purchased for just $15. The guts were removed from the plastic laptop case but when exposed the tiny existing processor fan and heatsink was very loud. Replacing the fan and heatsink with a larger unit the system is now silent. The end result is a great looking veneered piece of art that also functions as a PC.
