By popular request we’re going to start the weekly review/preview posts again.
Last week was a big week for the Bus Blaster, but there was a lot of other stuff too:
- Bus Blaster v2 is going to production mid February, the prototype has already been validated
- robots, Tornado, and Jamz got urJTAG to program the CPLD on Bus Blaster v2. A patch has been submitted to the project for review
- There’s new Logic Sniffer utilities to support hardware v1.04 with the new Winbond ROM chip
- A new SOIC Dangerous Protoboard was released. There’s only a couple left, but we’ll have more ASAP
- Work continues on a small Linux development board. This week SQKYbeaver updated the schematic with a new voltage regulator. See also the wiki, and the AT91SAM9260 quick start guide
- rasmus has a bitstream for the Logic Sniffer with RLE compression working on 16 and 8 channels. Please help test, scroll down for the newest release
- A case for Bus Pirate v4. Developer prototypes are on sale now, contribute code and get a refund
- Honken’s open source USB stack was ported to more microcontrollers. Free Bus Pirate v4 if you port it to a PIC24F
- We’re on Twitter and Facebook
- New workspace. More on that later
- In the last few months you may have noticed the machinegeek bringing some class to the blog. We think he had the best 27C3 conference coverage on the web, his posts were credited by Make and others. Join me in welcoming the machinegeek to Dangerous Prototypes. We’re got some other new bloggers testing the water, and you can join us too
This week will be busy too:
- Bus Blaster v1 is being tested and will be available soon
- The MCP2200 breakout board should be listed at Seeed this week too. Sjaak cut this one apart and put it back together, it’ll be fun
- We’re into CPLDs, so look for a couple logic-replacement CPLD breakout designs and simple device tutorials. A CoolRunner-II board is nearly complete, we’ll also do a XC9500XL board. Look for a comparison of these Xilinx CPLDs later today
- USB POV Toy, oh so hard to solder and program. Maybe someone will give you life this week
- More Dangerous Protoboards from Sjaak
- Will the Bus Pirate get an open source USB stack and move one step closer to production?
- We made a USB backpack for the SparkFun color Nokia LCD knock-off. We tried to use it with the LCDs Seeed could find, but the driver is different. Now it’s kind of an orphan project. We’ll probably write up the design this week anyways
- Less hacky stuff like advertising, site upgrades, and more are also in the works
What are you hacking this week? Our favorite project gets an SOIC protoboard.

I would say it will be a very busy week :D
Hi,
I am using the your MMA7455L breakout board to control a 3D cube displayed on a (SPI-modified Seeedstudio) OLED display:

My MMA7455L library is available in the forum:

Have fun,
Markus
We have a post about your lib queued, but I hadn’t seen the 3d cube, that is smashing! Does the lib provide the averaging code you used? I’m having problems getting the USB POV Toy to work the way I want, it uses the same sensor to reset the POV drawing (or it wants to:)
Cool! I love those vintage wireframes!
As far as your wonderful project with the color OLED and Accelerometer, can you mail me the code for it. I’d love to make this project. I believe I have all parts (hopefully)

Yeah, the values jitter around quite a bit without averaging them :) I used the dumb static average function first, but this reduced the refresh rate quite a bit, since it takes a long time to take for example 32 measurements.
I added a moving average filter, which works quite well now. The updated library code can be found in the forum thread.
I don’t know how much of this will get done this week, but here are a few projects that I have in the works. Classes start this week so I am not sure if that will make these more or less likely.
1. Pure 4000 series logic chip clock. I think this is a cool idea and I want something to show off. I need to actually get some chips and start prototyping.
2. Galvanometer based laser projector thing. I have a pair of galvanometers with mirrors attached and I want to build something to do a line drawing for fun.
3. Modify the #twach to only read a few twitter feeds. My friend wants a woot checker and woot has twitter feeds.
4. Finish updating my google site so that I feel comfortable with submitting it to this site and hackaday.
These are just some things that I need to get around to doing. Hopefully I can find the free time.
Good luck with the 4000 series clock. I did something similar on breaboard, first with 4 digits, then with 6, but it was mainly counter. With one or two more chips it could be transformed to simple clock. I used a lot of dumber chips, I remember 4060, 4518, and 4513 but there are others which integrate counter and decoder. 4513 was driving 7-seg directly (it outputs just few mA@5V) so it had almost no discrete components which looked cool (or at least I thought so).
Regarding the machinegeek postings: some are original and interesting, but reading all the repeated posts from Hack-a-Day make being subscribed to dangerousprototypes a bit tiresome :) Maybe the reposts can be reduced a bit?
I must say that this is my new favorite site on hardware projects! btw my buspirate looks smashing in the red acrylic case :)
Will the new projects be avaliable in the seedstudio webshop also?
Sure!
Seeedstudio is our main distributor (and manufacturor). We however get more and more webshops that carry our products.
– This Sunday I’ll be teaching a homemade sensor’s class, I’m trying to write the codes needed for testing them out. At the same time I’m learning the usage of the MSP430 Launchpad.
Not for this week but sometime after my finals:
– Blog post about sensor’s class
– Trying out STM32 Discovery board (on Linux of course)
– PiratePICprog contributions
