Free laundry redux

[Koala] was worried his pseudo smart card trick wouldn’t be considered a HackaDay worthy. We’re more worried the internet police will find this article and have us all tarred and feathered.

Jokes aside, it seems Laundromat owners sure aren’t learning. Long story short, using a Bus Pirate and a few techniques we’ve seen before for smart card hacking [Koala] is able to write whatever amount he needs onto his pseudo smart card; thus giving him a free load of laundry.

Laser cut and printable cases

If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut it with a laser or print it out of plastic. We’ve got examples of both.

[Stewart Allen] set to work designing laser cut cases for the AVR Dragon and the Bus Pirate V2go after seeing our post about on-the-go prototyping. We think this is especially important if you have an AVR Dragon as it’s been known to bite the dust if the bottom is shorted out. If you have access to a laser cutter you can download is DXF files and the models and cut your own.

If you don’t have a laser cutter but can get some time with a 3D printer check out the Bus Pirate V2go printed case and the Arduino printed case.

Storage for your hacking needs

Sometimes your project needs a lot of non-volatile ROM, right on cue [Matthew] let us know how to not only connect, interface, read, and write to SD cards with a PIC over serial, but also how to do the above mentioned with an old PATA HDD. For those without a PIC/serial connection don’t fret, [nada] let us know about his Bus Pirate SD card hack, of which our personal favorite part is the creative use of an old 5.25″ floppy connector as the SD card socket.

Bus Pirate preorder 2 update

bp-unbox-0

A few weeks ago we held a preorder for the Bus Pirate universal serial interface tool. We split the preorder into two parts due to a shortage of PIC 24FJ64GA002-I/SO chips. The first preorder is arriving worldwide now, the second preorder has a longer lead time. Here’s everything we currently know about preorder 2, it’s subject to change, but we wanted to keep you up to date.

Preorder 2 contains orders for 563 Bus Pirates. Seeed Studio noticed an error in our quality control testing routine that misclassified about 50 preorder 1 Bus Pirates as defective. We updated the test and passing units will ship immediately to preorder 2 participants on a first come, first serve basis. Another 500 PICs are scheduled to arrive after August 1, which should take care of most remaining orders.

Parts: Unboxing the Bus Pirate

bp-unbox-3

For months we’ve used our Bus Pirate universal serial interface tool to demonstrate electronics parts, so it’s only appropriate that the Bus Pirate get it’s own parts post. We recently had a Bus Pirate preorder, and today we received the pre-production Bus Pirate prototype from Seeed Studio. This prototype was mailed just a few days before preorder 1 started to ship, so those packages should start arriving any day.

Follow along as we unbox the prototype Bus Pirate, and connect it to a debugger to determine the PIC24FJ64GA002-I/SO revision that shipped with this board. Use this post to share your own Bus Pirate unboxing experience. Pictures and discussion after the break.

Bus Pirate preorder 1 ships

panelized-470.iijpg

A few weeks ago we held a pre-order for the Bus Pirate V2go, the first official Hack a Day hardware. We had initially hoped for a group purchase of 20 or 40 Bus Pirates, maybe 200 if it was extremely popular. In total, nearly a thousand Bus Pirates will be made.

The first 350 Bus Pirates (pre-order 1) have already been manufactured and tested. Seeed Studio has done a great job handling the orders, pre-order 1 should start shipping more than a week early. How long will it take to get to your mail box? It will vary for everyone, but our packages usually arrive from Seeed in 7 days.

Seeed sent us pictures of the Bus Pirate depaneling, programming, and quality control process. Check them out after the break.

Parts: 4×20 VFD character display (NA204SD02)

futuba-serial

Futaba makes vacuum florescent character displays that can be used as a drop-in replacement for common character LCDs. VFDs have a wider viewing angle, and generally look cooler.

Futaba’s character displays can be interfaced using the standard 8-bit or 4-bit parallel LCD interface, or a simple two-wire protocol. The protocol type is set by resistors on the back of the display, so it’s not particularly easy to change without a hot-air rework station. Today we’ll demonstrate a serially-interfaced VFD using the Bus Pirate.
