Bob the Robotic Head #hackfriday

Mike writes:

Hack Friday started a couple months ago buying a robotic head.  It comes with two servo motors and two electric motors.  About the same time I bought an Adafruit motor shield to control the head via an Arduino.  I have not had time to wire it up with other projects like the Cylon Pumpkin.  With Halloween over, I wanted to focus on the robot. Helping was receipt today of another Adafruit order from this past Sunday when they had a 10% off sale for Hack Friday.  Just in time!

The head is driven with the motor shield’s two servo outputs and two of the four motor controllers.  For now, a potentiometer is read to control the motor and a rotary encoder, interrupt driven, selects which motor to control (could be done with 4 potentiometers possibly better).  The motor shield leaves enough Arduino pins free (all analog pins and digital pin 2 which is interrupt controllable).  Eventually the head will respond to sensors and possibly talk via an Emic speech board coming from a sale at Make.

Making the hookup much more enjoyable is my new Hakko soldering iron – near instant controlled heat, making the old Radio Shack model seem so 1976.

I’m looking forward to seeing this project up and running (and talking) — it looks great so far!

It’s Hack Friday! (finally!)

All day today we’ll be featuring projects from around the web — tag your project posts #hackfriday on Twitter and G+ and we’ll post them up on the Adafruit blog!

You’re welcome to post your own #hackfriday projects, ideas, and aspirations in the comments here too.

What is Hack Friday?
Hack Friday is an alternative to Black Friday that celebrates personal initiative and creativity. Instead of mobbing the local box store at 4am, you sleep in, stay home, and work on your own projects with the people you love. A Hack Friday project can be anything you like, from gardening to programming to woodwork and beyond — the point is to encourage active making instead of passive consuming. It’s an unofficial, nationwide 24-hour hackathon.

Hack Friday — “There Are No Lines at the Work Bench!

BUT WAIT, THERE’S MORE!

In celebration of HACKFRIDAY we’re doing a 10% off sale today only!

Use code HACKFRIDAY on checkout to get 10% off everything in stock in the Adafruit store!

Arduino-based Handheld Bluetooth Game Controller #hackfriday

In the comments to our #hackfriday post, Chris told us about this project he’s been working on. It’s an Arduino-based Bluetooth game controller. He writes:

I’ve been on mission lately to design a handheld bluetooth game controller. I’ve made a prototype in the past but, it never was really usable as a gaming device. Although the concept worked well the form factor was not quite there.

Well after a few months of tinkering and several designs I finally have one!

The design is based around the Atmega 328 running the Arduino bootloader. There is a RN42-HID bluetooth module that allows serial communication between it and the microprocessor.

I wanted the device to be fully hackable so I designed it with headers for both the bluetooth module and the Atmega 328 chip. I can reprogram the bluetooth module to run HID keyboard or mouse (or combined), it can iterate as a gamepad, or it can reconfigured to run serial protocol and iterate as a virtual com port.

It works great for both Android devices and iPhone devices. I have it iterate as a HID keyboard and then run code to simulate the iCade, since there are already a lot of games that support this protocol. I also have code that just runs simple keyboard presses and this works great in games that support keyboard input. The nice thing about it is that it can be reprogrammed easily to accommodate any protocol that I need. I have also combined the regular keyboard and the iCade protocol into one code base and switch by holding a button down at boot – multiple protocols!!

Way to go, Chris! Awesome layout and design!

If you’ve got a Hack Friday project you’re working on, you can post it on Twitter or G+ with the tag #hackfriday or leave a comment on our #hackfriday post, and we’ll share it on the blog. Hack on!

Star Trek Game Controller #hackfriday

Inspired by the interface from the Star Trek: TNG episode “Peak Performance“, created this project using aluminum foil and an Arduino to play a simple ‘Snake’ type game. Good thing to have around if you need to take an arrogant Zakdorn down a peg or two.

jRover: a Mars Rover-style Robot #hackfriday

Jason writes:

jRover project. Running a VexPro robot controller. With 12 motors 6 for drive and 6 for steering. It has 3 ultrasonic sensors. It is built in the mars rover style using a rocker bogie based suspension. It higher level controlling software is ROS from Willow Garage. It uses opencv to detect the blobs of color we want to follow or drive through. I will post more actions videos as we get further along. I will also post its run at the +DPRG  outdoor robotics contest which is to be run on Dec 16th.

Great work, Jason! Thanks for sharing your project — hack on!

#hackfriday Gardening — Plant Some Garlic!

My project for #hackfriday was to plant some garlic. Now, conventional wisdom would say that late November is too late in the year to put garlic in the ground, but I’ve been planting garlic on the day after Thanksgiving for the past few years. Each time I’ve been rewarded with a great harvest in the late spring, maybe conventional wisdom is wrong.

This morning, I documented my standard routine so that I could share it with you.

The first thing to do is to break up the garlic into individual cloves (as in the photo above). You’ll notice that these cloves have green sprouts. While it’s not critical to have these sprouts (in my experience, some varieties of garlic don’t develop sprouts until they’re in the ground), they can be helpful to the plant in getting nutrients from the soil immediately after planting. While you can’t make the garlic sprout green on short notice, you can help it to acclimate more quickly by soaking it in a mixture of water and baking soda (1 qt water + 1 tbsp soda) for a couple of hours.

The next step is a clear a bit of land in your garden. Garlic is, for the most part, a hardy plant that will take care of itself. However, because it is a bulb, it requires well-drained soil to prevent rotting. An 8-12″ raised bed of topsoil works quite well. Clear any weeds out of your little plot and till the soil a bit to aerate it.

Next, you’ll want to dig some holes. Garlic should be planted 6-10″ apart. Use a shovel handle or large dowel to make the holes.

Lay out your cloves of garlic and then drop them in! The green sprouts (if any) should point upwards and the flat root section should point down.

Rake over the whole bed to fill in the holes and aerate the soil some more. If the soil is particularly dry, water the ground a little bit. If you expect a cold winter, cover the ground with straw or gardening paper. In the case of paper, you should remove it in early March when the weather gets warmer.

And that’s it!

Depending on the local climate, and the weather for the next 6-7 months, your garlic should be ready to pick by mid-June!

Happy hacking!

#hackfriday Holiday Make-A-Thon 2012 at Milwaukee Hackerspace

The folks at Milwaukee Hackerspace are having a #hackfriday Holiday Make-A-Thon at Bucketworks today!

Pete writes:

It’s no secret that we love making, but did you also know we love helping others make things as well? It’s true… and one of the ways we like to help others is by taking part in the Holiday Make-A-Thon that happens at Bucketworks the day after Thanksgiving.

Why bother putting up with the malls and the traffic and the crowds so you can try to get some great deal on the latest gadget that will be out of date in six months. You’d be much better off joining us at the Make-A-Thon where we’ll help you make something that will serve as a great gift this holiday season.

We’ve got a few things planned, including ornaments you can decorate yourself (new designs for 2012!) You can also learn how to solder, and walk away with an awesome electronic blinky Milwaukee Makerspace logo. We’re also hoping to let people design their own cookie cutters that we will then 3D print for them. Exciting! Who doesn’t love whimsically shaped cookies!?

There will be other activities and things to make, but you’ll have to join us to find out what they are. So head down to Bucketworks on Friday, November 23rd, 2012 from 12pm to 5pm and make with us. (More details? See the Facebooks.)

This is a family-friendly event with lots of awesome people — if you’re in the area you should check it out!
