Update, Saturday July 4th, 2009: All preorders are closed.
A probe cable makes it easy to connect the Bus Pirate to a circuit and get hacking. Good test clips make quick connections on cramped PCBs without causing short circuits. We made two cables for the Bus Pirate v2, keep reading for an overview of our designs and list of part suppliers.
Friday, July 3, 2009 is the last day to pre-order a Bus Pirate. There’s only two days left to get your own Bus Pirate, fully assembled and shipped worldwide, for only $30.
Stairs are one of the most commonly faced mobility challenges for a robot. This robot’s design eliminates the need for a complex drive train or computer, and instead uses a clever mechanical design to climb stairs. Version three of the robot uses five servos modified for continuous rotation, a Picaxe28, sharp IR sensors, and bump sensors.
The Great Internet Migratory Box of Electronics Junk, or T.G.I.M.B.O.E.J. has turned one. In the last year, they’ve learned a lot of things. They learned that lots of people are willing to contribute. Hundreds have signed up on the site to participate. Theyve also learned that laziness is the key road block on this project. The boxes that have stalled generally sitcollecting dust, simply because someone hasn’t bothered to ship it off. If you’re curious what kinds of stuff ends up in one of these, check our initial post. There aren’t any guarantees though, it all depends on what people toss in.
Using an IR thermometer, there are two ways to go about building a thermographic camera. The first uses a pan and tilt head. Scan lines are emulated, as a computer controls panning from left to right, taking a temperature sample from each step. Vertical resolution is accomplished by tilting. Another method uses a web cam attached to the thermometer. The thermometer’s laser pointer is captured with temperature annotations, as the computer records the field of view. We think the best outcome can be found with a combination of both methods. The video embedded below demonstrates the results. This would be a good addition to the Autonomous paintball sentry.
With the 4th of July around the corner, we thought it would be a good idea to give a controller wrap up and show you how to make some ignitors. Last year we covered a microcontroller based fireworks launcher. If you like the idea of a controller but don’t want to run all the wire, we have the wireless fireworks controller. Adding a little twist to the wireless scene are cell phone triggered fireworks. Maybe controllers are not your cup of tea, you could try to microwave your fireworks. After the break we show you how to make ignitors from a diode and a match.
DARPA has awarded an extension to AeroVironment for their work on the Nano Air Vehicle project. The prototype seen above, called Mercury, is an ornithopter which means it flaps it’s wings. It is the first to show controlled hovering. Look closely, there’s no rudder or tail. Mercury uses the two wings for both lift and control. Ornithopters themselves aren’t new, we’ve even covered them before. Usually they use the flapping wings for propulson and a tail to steer as they travel like an airplane. We would really love to see some detail shots of Mercury.
[Kyle McDonald] sent in his latest project, a software keylogger that twitters what you type. He wrote it using C++ and OpenFrameworks. It logs each keystroke, then it posts to twitter 140 characters at a time. To protect himself, he set up a whitelist of private strings like passwords and credit card numbers that would be stripped before posting. If the twypewriter followed him, his keystrokes could be recreated.
Most of the parts we use operate at 3.3volts, but we still run into a lot of old 5volt stuff, and an occasional 2.5volt or 1.8volt part. This post explains how to use the Bus Pirate’sopen collector pin mode to interface with parts at different voltages.
We’ve got more details and some example scenarios below the break. Yup, this is another Bus Pirate post. It’ll all be over soon though, because there’s a few days left to get your own Bus Pirate for $30, fully assembled and shipped worldwide.
Snow days are great, but generally you still have to wake up to find out if it is a snow day. [insingertech] decided to make a system to solve this problem. He made an alarm clock that would automatically de activate if school is cancelled. What a pleasant surprise it would be to just wake up and find that you had been allowed to sleep in. It is using an Arduino and a python script to control the state of the alarm based off of an online school closing announcement. You can download the software from the instructable.
[Michael] has a keypad in his previous car’s door and he missed it enough to hack one into his Dodge Caliber. He bought a Ford keypad and mounted it inside his door with some custom electronics. He started with an Arduino nano to receive and authenticate button presses. This then splices into wires in the door that control the door lock. The program has a 5-digit code to unlock the door, but simply pressing 1 twice will lock the doors. He also implemented a lockout feature to prevent people from brute-forcing the combination. Although it isn’t wireless, it’s significantly simpler.
The folks over at basicmicro.com are working on a massive LED display. They currently have one 32×32 RGB panel working. It displays 50 fps at 140 hz but the one above is only running at about 24 fps. The final display will be 40 of these panels. This thing is going to be massive. We have to wonder how this compares, financially and performance wise, to the commercial signage that displays videos.
Microchip’s 25AA/25LCEEPROMs are data storage chips with a simple 3-wire interface. The 25AA/LC is an SPI version of the common 24AA/LC I2C EEPROM. It comes in capacities of 128bytes to 128kilobytes. We looked at the smallest, the 128byte 25AA010A.
There are Bus Pirate demonstrations for most types of serial EEPROMs. Check out our previous 1-wire (DS2431) and I2C (24LC1025) EEPROM posts.
Continue below to see our test circuit and a demonstration of the 25AA010 EEPROM. We used the Bus Pirate to play with this chip from our PC. For a limited time you can get your own Bus Pirate, fully assembled and shipped worldwide, for only $30.
This quick little hack is beautiful in its simplicity. Need a macro lens to play with? Simply rip the lens out of a pair of binoculars and tape it to the end of your slr lens. The result is pretty good. If you need something a little higher quality, you could always hack an extra AF lens.
We’re only four days into the Bus Pirate pre-order, and we’ve exhausted the supply of PIC24FJ64GA002s available in Shenzhen. Thank you for supporting Hack a Day’s first official hardware pre-order. You helped make it a huge success, and we definitely want to do it again in the future.
We weren’t kidding about the PIC shortage. Seeed sourced all they could from Shenzhen, and then tried Hong Kong. It’ll take 4 to 6 weeks to get more.
If you already ordered a Bus Pirate then nothing changes, your Bus Pirate will ship ASAP. In fact, PCB production should start a few days early. The first pre-order item name starts with “[Preorder]“.
New orders are now forwarded to a second pre-order. The new pre-order will take 4 to 6 weeks longer. It should ship about 6 to 8 weeks after July 3, 2009, but we’ll try our best to get it out sooner. The new pre-order item name starts with “[Preorder 2]“.
