Hey guys Im moving over to blogger for my maker blog. You can go ahead and visit it at make.peterfoxflick.com, which if that dose not work (and I have not clue why it doesn't ) go to foxmakerspace.blogspot.com.
Check out my new tutorial on how to build a ATtiny Dark Detector.
This week I'm in back in the mother country (Canada). So after unpacking I got my paper circuits out. I first stumbled across these circuits from MIT's high low lab while trying to program an attiny85. Now I get to try it out myself. The first circuit does not have a resistor and was mainly to test that the led and battery worked. After that I tested to see which resistor worked best, 47 or 330. 47 is mathematically better, but I always have used 330 in other projects. All of the components are SMD and I'm using copper tape to make the circuit.
The CNC mill is assembled, and the electronics and program is in place. Just one problem. POWER :( It turns out that the power adapter that I'm using is not strong enough to power three stepper motors and an Arduino. Which means that sometime this or next week I'm going to have to pick up another power supply. Fingers crossed that this one works.
I've recently started to build a cnc mill from this instructable. So far it's been going smoothly, I'm going to use rubber tubes for the couplings because they're impossible to find. So far everything I've used to build it is from Lowes or Sparkfun.com. I should be finished with it in two weeks. Fingers crossed.
This year for our High Schools last football game we made and deployed UFOs. To do this we connected a Attiny85 to an LED and coin battery. The Attiny85 would start the LED after a few seconds. After that the LED pulses. The LED-Attiny-Battery combo were put in a balloon. We filled the balloon with helium and we had ourselves some UFOs.
The UFO launching failed in the fact that no one in the stands could see them past the stadium lights but the people in the parking lot saw them all glowing in my car.
My parts arrived. I got the Micro SD Shield from Sparkfun. After following the Quickstarter Guide I was on my way to logging data. I started by loging the amount of sunlight that hit my desk. After finding a batter for my arduino I was able ti log the sunlight on my porch. Although most sd cards use pin 10 thris shield uses pin 8 for card select. It does mean that you have to convert thr code over, but most of the time the chip select worked as pin 10. Still a mistery for me,
A few years ago (2006?) my Dad bought a robot. It was really cool and was controlled by a computer. The robot used treads to move and an Xbee to receive commands. After a while it was put in a box and we moved to a new house. This past year I found it again and tried to get it working. The problem is the company that made the computer software that runs it it gone. My solution, an Arduino.
After a few months I was able to send programs to the Arduino that then made the Robot move. I also learned about drivers (chips that turn control signals into motor movements) and how to program with functions. (lines of code that refer to other code, ie if i say do X, then it finds the line of code that says what X is). They save a ton of room.
Now that I have the code for serial communication an Arduino Esplora remote controler isnt far away.
This weekend while picking up some parts at RadioShack I stumbled upon a 3D Led Cube Shield for Arduino. The instructions are very detailed at first then as you go on you have to start problem solving. My favorite part is that the layout for the leds is drilled into the shield. You actually use the shield as a layout for the leds! How smart is that.
To get the sketch for Arduino to run the Led you have download the Support Files. The included sketch has a lot of examples and does a good job of describing each part. Although it will still be awhile until I'm able to write my own from scratch.
