Coin Cell Jump Starter Project

at 11:34 pm. Filed under Cool Gadgets, Crazy Hacks, Electronic Hacks


 

Ted Yapo is designing a crazy project idea, it is a Coin Cell Jump Starter! Just think next time you need to jump start your car you simply need to locate a coin cell and use this system to suck the power out in a usable way to start you car. Is it practical? Not really but it is cool is this theoretical idea would work. It is a total work in progress, I am looking forward to seeing a video of a car starting soon.

“So, if I can create a boost converter to charge the capacitors to 14V from the cell that’s at least 6527/10800 = 60% efficient, I should be able to start a car from a coin cell.

The first rough plan is to make a simple inductor-based boost converter to charge a similar (possibly identical) capacitor bank over perhaps 24 hours, then start the car with the capacitors in place of the usual battery.”

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.”

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.”
