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.”

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.

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.

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.”
