Squink – PCB Printer

 Squink - PCB Printer

 

When you are making a new PCB design don’t you wish you could just print out the design instead of sending your Gerbers out for manufacture? BotFactory has created a PCB Printer called Squink, it prints using conductive ink and places dots of conductive adhesive where each SMD part will be placed. Best of all the machine then does a pick and place of all the parts onto the design. The entire process takes about 15 to 30 minutes depending if you want the optional heat curing to be performed. Just think of the ability to spin your board design a few times in a day. Of course this might not be right for everyone. I am not sure what the work around is to incorporate some through hole parts and vias for double sided designs. These days a double sided board is about the same cost as a single sided board but gives you much more flexible trace options without using jumpers.

If you are interesting in playing with this technology you can jump on the KickStarter for $2,999 (only a handful left at this price)

Mini FM Transmitter

If you are looking to get into the spy game have a look at your first gadget you need here, it is a Mini FM Transmitter.

“It transmits FM waves so you could easily receive the signals on your mobile phone, radios, etc. As the name and the picture indicates it is very small and is approximately the size of a 9v battery clip. With this FM transmitter you could start your own mini FM station. The circuit uses BC547 transistor to amplify the signal and then frequency modulate it. It uses “frequency modulation” most commonly known as FM, the same principal to transmit audio signals captured by the microphone.

Components

BC547 Transistor
An microphone
A variable capacitor 47pf
An Inductor (see steps for description)
4.7k Resistor
330ohm resistor
1n capacitor (102)
10p capacitor
9V battery
LED(optional) “

Richard Turere Invents Livestock Protection Device

 Richard Turere Invents Livestock Protection Device_2

 13 year old Richard Turere lives in Kenya. Livestock is very important in their community, however lion are very smart and often kill their animals. The lions wait till everyone goes to bed before attacking. The first attempt at outsmarting the lions was to build scarecrows but the lions soon realized that since they were not moving around that there were not real people and didn’t pose and danger. Using a solar panel to gather electricity, a battery to store it and a car turn signal flasher to blink some lights he was able to place some lights at random locations around the pasture. This makes the lions think that there is someone walking around watching over the livestock at night. What a ingenious idea from such a young inventor.

Blackstar Hexcopter

at 7:45 am. Filed under Cool Gadgets

 

If you are getting into quad and hexcopters have a look at this one that Atarix777 demonstrates. He has built it in a way to keep the cost down without sacrificing performance. It has a total weight of 2.3KG so it sure isn’t a compact unit! It is an FPV system which allows the user to view the image of the on-board GoPro. Check out the 11 minute mark for a nice flight around.

Fletcher Destroyer Transmitter

at 11:20 pm. Filed under Cool Gadgets

 

JLTSoft demonstrates how his Fletcher Destroyer Custom Transmitter works. Instead of just making a remote that would directly command the servos and motors as fast as they can be the transmitter is designed to reproduce the actual delays that would be present in the real ship. There is an Arduino that controls the transmitter and the audio clips are stored on an SD card.

 Maker Camp Season 2014

 

 Check out Maker Camp 2014, a great way for kids to have some fun building projects. Check out the guest Buzz Aldrin who was a guest in the video below. There are some audio issues that make the video a bit hard to watch but if you can get over that it is worth it.

About Maker Camp

Maker Camp is a free summer camp for building, tinkering and exploring available online and in local neighborhoods. Through Google+, YouTube and local “campsites” young inventors and artists around the world can make awesome projects, participate in epic virtual field trips and meet the world’s coolest makers.

 On Mondays through Thursdays, new projects are introduced every morning by an expert “Guest Maker” who walks campers through the steps to making the project, offering tips and advice. In the afternoon, the mentor hosts a Google+ Hangout on Air to offer campers a chance to ask questions, and share their projects with photos and videos. On Fridays, the Camp Director hosts a virtual field trip to epic destinations via a Google+ Hangout-on-Air, broadcasting a live experience to anyone who wants to tune in on Google+ or YouTube. This year, campers will get to visit Google’s self-driving car group, NASA, Disney, LEGO and more.”
