Google’s Project Wing Delivery Drone Prototype

at 11:29 am. Filed under Complex Hacks, Cool Gadgets, Insane Equipment


Can’t wait till this style of delivery method is available. Tested had a first hand look at the Google Project Wing Delivery Drone Prototype. Not that it will have a direct replacement for things such as pizza delivery since the payload needs to currently be quite small but the flight and delivery method is great. Scaling these up to handle larger packages would make it great for package delivery directly into your secure back yard in minutes. I guess the only concern people will have is what happens when something goes wrong and it falls from the sky and knocks someone in the head.

Nokia Phone Arduino Shield

Nokia Phone Arduino Shield


If you have one of these classic Nokia phones in your desk you might want to put it to use.

Via: EEVBlog Forum

“I am making an Arduino shield to interface with old Nokia phones. I’d like to keep the price around $20 for the shield, cables, and phone. If I can get some software help from the community, this will be great for interfacing projects with the internet.

For photos, code, and a detailed writeup please check out my post at http://paxinstruments.com/nokia-phone-arduino-shield/

  • Should the shield be for a specific Arduino board or be configurable? The AltSoftwareSerial library uses specific pins for different Arduino boards.
  • Is it fine to have the phone and serial-to-USB chip both connected to the Arduino RX/TX lines?
  • Do we need the level shifters?
  • Is there a better Nokia cable that also provides power?
  • The Nokia 3100 needs a battery to run even with the power cable inserted. Is there a way around this?
  • Is there a better target phone?

Meter Clock using a DS1307 RTC and Trinket Microcontroller

Meter Clock using a DS1307 RTC and Trinket Microcontroller_2


This Meter Clock uses a DS1307 RTC and Trinket Microcontroller to show the current time in style. The meters are PWMed into position directly from a few pins of the Trinket. The meters are ammeters that have had their scale replaced by Hour and Minute scales. You can see the scale adjustment calculated below, another alternative would be to do it in code as I did with the Multimeter Clock

“For a 5 volt Trinket and 50 microamp meters, for full scale deflection we need a series resistor on each meter to keep the current less than or equal to the maximum current the meter can handle. Using Ohm’s law, R = V / I = 5 / .00005 = 100,000 ohms (100 K). You will need two of these resistors, preferably 5% or better tolerance. These are commonly available from electronics suppliers. If you want precision in calibrating the meter, you may want to substitute each resistor with a 100K potentiometer with a series resistor, perhaps 10 to 47 K. This allows for tuning the resistance. When I designed the project, the 100K resistors gave accurate enough time without needing potentiometers.”

RC Airboat Rescue

at 11:55 am. Filed under Cool Gadgets


TraxxAlu has a nice RC Airboat and Truck.  Watch this cool video where the RC Airboat gets stranded and needs to be rescued. Best of all it is all done remotely using FPV. I can see this working full scale quite well also!

Robot Bug

at 4:55 pm. Filed under Cool Gadgets, Electronic Hacks



This Robot Bug is very elegant. It has an Arduino for a brain and PING sensors for the eyes. 

“Software is quite straight forward, a giant state machine, that takes input from the sensor, every now and then. halfbug has 5 different movements, one regular forward movement, one turn (left and right) and one turn hard (left and right). In addition to that halfbug has a head movement (left-right-straight) or looks left when turning left. Both, leg and head movement is controlled by separate sub-state machines.”

Bug Zapper Illuminated Bike

 Bug Zapper Illuminated Bike


Steve from Rimstar.org has build an illumination system for his bike. Most of us would use a battery and a light right? Well Steve is using the bike power to generate thousands of volts and spark gap to warn people that a bike is coming. It has the added benefit of keeping people from wandering too close to the front of the bike!

“Want to make your bike create sparks as you drive?

One way I found is to add on a Wimshurst machine, an electrostatic machine that produces sparks. The cool thing is that the Wimshurst machine works by rotating two disks, normally using a hand crank… but connect it up to your bike pedals and now you rotate the disks as you pedal! To make it cooler, this one even uses a 3D printed sprocket!”

Capacitive Touch LED Table

Capacitive Touch LED Table


This Capacitive Touch LED Table by uses an arduino to drive a neo pixel strip and uses the capacitive touch library to allow the aluminum trim to become a mode switch. The code is available to you can build your own if you like. She cut a hole in the top of an old table and mounted the electronics under glass. Looks great and the effects are nice.
