Alfa 159After the successful modification made to the gearbox cooling system https://jabawoki.com/2016/01/27/alfa-159-gearbox-cooler-modification/ I found that, while the cooling was perfect while the car was moving over 30mph, there was an issue at lower speed. On more than one occasion I found that if I sat in traffic, slowly edging forwards towards a busy roundabout, once I got to the roundabout and accelerated away, I would have a shift flair for the first gear change. This would disappear by the second change so was clearly a cooling issue where the lack of airflow meant that the gearbox temps would rise in traffic until you had airflow again. The fix is/was simple. I just needed a thermostatically controlled fan adding to the radiator so that I could generate airflow at low speeds. After doing some basic research I found a really nice 5″ fan from SPAL, available from Merlin Motorsport. This unit was very high power and perfect for the job but I needed a thermostatic control solution as well. Merlin had the ideal solution as well, a Davis Craig Thermostatic Adjustable Fan Controller. This fan controller was ideal as it had a separate external temp sensor that was fitted into the radiator itself which meant I did not have to cut into the oil lines to make the mod. Fitting required removal of the bumper as usual, but that gave me an opportunity to fix a crack that was temporarily repaired previously. Adding the fan was very easy as it came with its own mount kit that essentially used special plastic ties that passed through the fins of the radiator and clamped it securely to the rear of the unit. Fitting the fan controller was a little more tricky but only due to the very short wire run on the temperature sender which meant it had to be within two feet of the fan. Fortunately it nestled perfectly between the ECU and the headlight! The unit can control two fans but I am only using it in single mode. It has an adjustable temp trigger so mine is set to 75C which is a reasonable point to start testing from. The added digital temperature display is also quite useful for diagnostics! I will have to see how it pans out but I am pretty confident that this will sort the last pesky shift flairs for good! Related Images: [...]

InfoSecOk, its been ages since I actually had snort up and running, so long in fact that the last time I used it, ACID was still the best way to deal with the alerts! Well after a couple of days (well a couple of hours here and there at least) I have a fully functional set of snort sensors in place on public and private segments of my networks, all feeding to a centralised database with “BASE” handling the analysis! woohoo. small victories are the best! I can definatley say its come a long way. It was much easier to install, and only took a small amount of syntax debugging to figure out the configs. During my research / re-learning curve though it would seem that version 2.8 with the stream5 processor is not as good as version 2.4 with the flow processor at detecting portscans. This was certainley the concensus of the community, and after a bit of playing I can agree. However, I now have sfPortscan running with stream5 and its seems pretty accurate to me, so I am certainly happy with the results. BASE is also a welcome move onwards from what used to be a very clunky interface. It seems light and intuitive, with decent features. I think it could do with the addition of some basic graphs, rather than having to use the graph engine to define your graphs each time, but on the whole i think it is certainly a good alternative to spending a large amount of money on a commercial product. Certainly the ability to abstract the managemnet interface, data storage and sensors from each other gives you a highly scaleable model to use a basis for a large scale deployment. Of course, if you don’t fancy the pain of compiling code from scratch, or your just dam lazy, check out EasyIDS for a complete “IDS in a box” that gives you everything I just said with none of the hastle! ….You just can’t ingore the momentum that opensource has gained 😉 Related Images: [...]
Alfa 159 / ElectronicsWell, I continue to work on this and now have a beta unit in my car on a long term test. It is pretty rough around the edges and has one major(ish) issue that I am working to resolve, but its a good starting point to work from. So what I have now looks a bit like this: (click to enlarge) Its still a very simple design that uses as few components as I can, but as a result it has some issues: As the the LEDs are quite hungry (50Ma each) the ATMega328 & the voltage regulator has to work hard to feed them. The above point causes a small delay in start-up of the unit of around 200-300ms. This delay is a problem as the unit is powered by the feed to the brake light, when the brake is pressed, so in essence it adds a small delay between the stop/tail lights of the car illuminating and the high level brake light. Long term this is unacceptable, but for now its a work in progress so I can live with it. The first generation PCB was designed to fit into the dust cover of the brake light, but after I attached the ribbon cables for the LED’s it didn’t fit so is now wedged under the parcel shelf for now. This gives me easy access form the boot to change the unit as I progress the design to remove the delay and make it instant. Here is the mock-up of the PCB using matrix board (left to right we have the finished design, the component layer, the jumper cable layer on the front, and the soldered join layer on the back):        And the finished article looked like this: In the end I decided to opt to hot glue the LED’s into the reflector and wire them back via a ribbon cable to allow me more flexibility on changing the circuits easily: Long term I intend to make a unit that can replace the original light bar, so the LEDs will be mounted direct to a PCB that will be installed into the light bar in some way, or easily attached to the back of the reflector housing, not sure which yet. I am working on a number of new designs at the minute that remove the delay and am getting some help from a true expert in the field of automotive electronics who actually designed stuff  that is used in the Mclaren MP4-12C. The current V3 unit that is in the car looks like this when operated: You can download all of the project files (sketch, layout & schematic) from the downloads section. Watch this space for V4 of the unit. Related Images: [...]
General…..put simply, because you have to! Now, don’t get me wrong, there are a thousand reasons for the upgrade, but did you know about this one? There is actually a very serious and technical reason that you should upgrade. I’ll try and explain it to you in lay terms…. The current “2G” iphones operate on the GPRS/EDGE Networks (I won’t get into the technical stuff, use wikipedia for that). Now you will think that actually that’s a good thing, better data usage is good news surely? Well it would be if their was not one simple problem with the 2G network. That is that you cannot use voice and data to the same endpoint (i.e. iphone) at the same time!!! Yes, that’s right. You cannot surf and chat simultaneously! Now, this has never really been a problem before a device like the iphone, as most of use would use the data facilities on our nokia or sony so infrequently that we never noticed a problem, however the iphone, being a data hungry beast, is a regular user of data, without your permission! What this all equates to is simple. If you iphone decides it needs a data connection, say to update its email or something else useful, and at the same time, someone tries to call you, guess what, they don’t get through! This kind of defeats the object of the iphone qualifying for the use of the word “phone” IMO! So whats the answer? simple, upgrade to a 3G phone! this makes use of the new third generation network (HSPA/UTMS), which of course, being data centric, allows simultaneous use of voice and data from a single device. What more of an excuse do you need to go and get that upgrade? Related Images: [...]
InfoSec……can be reverse engineered by mankind. Its a simple mantra, but one that has served me well in security. Think of of this way, it doesn’t matter how intelligent you are, someone, somewhere is more intelligent! When it comes to security this is never more true. As we all know, security is asymmetric, in so much that the effort required to secure something is significantly more than that required to break into it. Given this point, it makes the mantra even more relevant! If security was symetrical, you would have a 1:1 effort relationship, however, as its not, (we will for the purposes of this article assume its 2:1, i.e. double the effort required to secure), it would theoretically take less brain power than it took to create the control to break it. Obviously I accept that this is a very simplistic representation of the point, but one I think is valid. Related Images: [...]
