Wow, it’s been almost a year since we’ve made some Christmas DIYs. To bring them back to life, we are featuring it here again and well tell you to go make yourself one by following our directions here.

BTW, we are going to go buy a real Christmas tree this year. (Well it’s plastic but not LEDs…)

As you know, the team of moonlighters at Zedomax.Net has been working on new paid wikis. We belive this concept of paid wikis will blow up soon and we have just started diggin’.

We first made Five Dollar Wiki, One Buck Wiki, then EntreWiki.

Now, we introduce you to the new younger brother, The Quarter Wiki where you can buy a page for just a quarter!

That’s right, our motto for this new site is, “In Wiki We Trust”.

We are still working on some functionalities of the site, so don’t blame us if you find a page under construction. We just wanted to let you know heads up on the new website so you can go reserve your pages before all the good ones get taken.

The Quarter Wiki is a new paid online encyclopedia where you can buy your own page for just a quarter.

Unlike Wikipedia, you can add videos, RSS Feeds, advertisements, and GoogleMaps to a page on the QuarterWiki.

More simply, QuarterWiki filters spam by charging a small fee for each page so you don’t have to deal with it.

To get started with QuarterWiki, sign up for an account and search for your desired words you’d like to purchase.

Check out the Part 3 of “HOWTO make sounds with Ardunio” and learn to play melody.

Bit-Banging Sound
To bit-bang sound we toggle an output pin at the desired frequency. To play a musical note, we need to use specific frequencies and play the sound for a specific amount of time.

Generating the desired frequency big-bang style means figuring out what the period or cycle time of the desired frequency is. This is easy to calculate, it’s the reciprocal (1/F) of the frequency. As we found in part 2, 1KHz is 1000 cycles per second. So, one cycle takes 1 one-thousandth (1/1000) of a second or 0.001 seconds (1 millisecond). We need to toggle the pin at this rate so we want to keep it low for 1/2 the time then high for 1/2 the time. Therefore we want to set the I/O pin low for 500uS, then high for 500uS and do this over and over for as long as the duration requires.

Here’s a cool audio and video controller DIY using Arduino.

This is the future for all of those unwanted typewriters, yes that is right all those old typewriters that have been abandoned by their owners and left in cupboards and basements are evolving into terminators.

Or maybe it is just a piece of artwork which just happens to use all of the old components from a typewriter that was left lying around, it looks pretty cool and is an excellent use of an old piece of equipment.

I still prefer the first explanation!

This is kinda cool way to control an LCD hooked up to Ardunino with browsers including your mobile phone.

In conclusion, this code may be pretty ragged, but the concept is what is important and it should be enough to get you started. You obviously can’t do anything too intense with this. It could be used to do some simple but cool things though such as controlling your house from your cell phone, or feeding your dog or cat over the internet, etc. Once again, please e-mail me if you need help getting it working for your project.

These great little lamp kits come on a sort of circuit board type of material, which needs to be trimmed up and then fixed together without any glue or anything and then connected to a nine volt battery.

They look like they are a bit of fun, but you are going to have to ask the question, Why? There are four sets to choose from, just in case you feel like you may need to buy the whole collection or something.

They are all priced at $19.99, nine volt battery not provided.

Here’s the video if you can’t see it.  (some kinda YouTube bug…yes blame it on the big company)

Cool, check out this awesome 3-Axis servo motor drawing “HackADay”. You can get the board for really cheap from this guy.

The preprogrammed AVR microcontroller must be purchased directly from Uli Huber. We do not carry the chips.

Please include $5 shipping and handling for destinations within the continental United States. For all other areas, please include $7 for shipping charges.

For those only interested in purchasing a single bare pcb board, shipping and handling can be avoided by sending us the cost of the pcb and include a self addressed stamped envelope with your order. Please attach three first class stamps to the envelope with your legible return address. We suggest using cardboard floppy disks envelopes that can be purchased at office supply stores. US only.
