Circuit Breaker Works in Slow Motion

at 7:51 pm. Filed under Electronic Hacks

 

 

We have done a teardown of a 100 amp breaker in the past but it is really interesting to see how they operate in slow motion. Warped Perception has taken a common 15 amp breaker and filmed the 2 states in slow motion. Breakers trip with a slow overload condition which takes a bit of time and a short circuit where the circuit breaker trips almost immediately.

Binary Clock Build

at 9:44 pm. Filed under Electronic Hacks

This Binary Clock Build project by JD is enclosed in a custom acrylic enclosure. 3 buttons are used to adjust the time, the binary clock is displayed for your leet friends. For the regular folk there is also a time display on the LCD. The System is powered by a Parallax Popeller. With 40 pins the Propeller has enough pins to drive each LED direct, the buttons are also all connected direct. The LCD is a serial LCD so that just required one data line but there are still available pins so chances are a standard LCD would also work.

SMS Message usage with GSM Modem and Arduino

at 10:35 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

iforce2d has a great demonstration of how to play with SMS Message usage with GSM Modem and Arduino. He goes through lots of interesting AT commands that do the actual transmission and read of the SMS messages. I can think of lots of useful uses of this type of device since an SMS message can be long enough to pack some interesting data chunks such as temperature issues (low temp high temp), door opening etc. The tutorial also goes through using the module to perform HTTP commands.

Water Meter Cloud Monitoring Interface

at 4:15 pm. Filed under DIY Hacks, Electronic Hacks

 

 

In some areas water meters have methods of connecting external monitoring equipment to determine water usage over time. This is normally done by a switch that pulses after a certain amount of water consumption. This was the case for . He has a water meter that has an internal reed switch which closes once per revolution of the last metering wheel of his water meter. He has created a Water Meter Cloud Monitoring Interface which uses atmega328p-pu microcontroller and an esp8266 controller. The system sends data over wifi to the Blynk cloud service to allow the data to easily be stored and monitored over time.

“The esp8266 controller is not very power efficient and cannot run on the batteries for long time. And we would like to use it as web server any time, so it must be powered by the external power supply. It is not good idea to connect the water meter directly to the esp8266 controller because usually the water meters are installed in the dark, tiny space without any access to the external power outlet and WiFi access.”

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.”
