New feature – Stores

New feature - Stores

We have a great new feature to announce, Stores.

We know that our site owners make some amazing things and sometimes people would love to purchase one of your hacks from you. Well now you have an easy way to sell your stuff. Why make one when you can make 5 or 10 for so little extra work, and offer them …..

Freedom555bot: Don’t we all Deserve a little Freedom?

Freedom555bot: Don't we all Deserve a little Freedom?

Here is my entry for the 555 contest, a robot that can be set free on any ferrous metal structure. It has rare earth magnets for wheels (covered in hot glue for traction) attached to micro servos modified for continuous rotation. The bot closely resembles the Beetlebot by Jerome Demers, as it uses limit switches to change the direction of …..

556 USAT

556 USAT

Blurb:

This is an entry targeted towards the “gratuitous use of 555s” category with a specific emphasis on horribly misapplying analog circuits.   Behold, the Universal Serial Asynchronous Transmitter!!!

The design is based on a chain of 9 (1 start bit + 8 data bits) monostable-configured timers set to trigger each off one-by-one.  The falling-edge triggering is done via a series capacitor …..

We are accustomed to objects behaving the same way not matter what our mood or how we treat an object. A book behaves the same to someone who loves it and treats it as gentle as possible as it would to another person who hates the book, almost tearing out the pages while reading it. What if that where to …..

556 Obligatory multi-vibrator entry

556 Obligatory multi-vibrator entry

Short Blurb:

For this entry I (apparently) wanted to see how much frustration my nerves could take as I took on the challenge of freehand soldering an interesting light blinking thing.  To make things even harder, I used bare 22AWG solid copper wire to provide some structural support.  This meant if you lingered to long soldering anywhere on the wire, its other …..

556 High-Current Driver

556 High-Current Driver

Quick Blurb:

I needed some sort of driver with variable frequency & duty cycle to drive motors/solenoids I was playing with.  Not content to buy one off the shelf and wait for shipping, I went ahead and threw this together.  The design was CAD’d in EAGLE and etched using the toner-transfer / cupric chloride process.  The heavy-lifter is an IRL540N N-Channel …..
