Eastern Cape Rally Championship 2012 Round 2

Last weekend I took a drive out to the tiny town of Loerie, EC to go checkout the 2nd round of the EC Rally champs organised by the Algoa Rally Club. The event took place just two short weeks before the popular national VW Rally on 13-14 July 2012.

The Parc Ferme for the day was at JC’s Pub in Loerie, which hosted the service park as well. It was an early morning start of 8AM, with the intention of finishing off with plenty of time for everyone to make it back to PE for the rugby.

The rally had a smallish turnout of 10 vehicles, but some tough routes lead to the retirement of 4 of the vehicles by the end of the 10th stage.

The first 2 stages were tar stages run on the van Stadens pass. These were run twice each before moving onto the 3 dirt stages on the farm roads around Loerie, which were also run twice. I was fortunate enough to grab a ride with one of the organiser to different points on the stages to get some photos.

Once again I unfortunately don’t have the final results, but I’ve been told there are plans to get the club’s website back up to date. Although I didn’t get many great shots, it was still a nice day, and the lack of rain during the event was a nice change from the previous rallies I’ve attended. That being said there was still a fair amount of standing water from the previous weeks rains, which surely had an impact on the retirements.

I’m a bit sad that I’m not going to be around for the VW Rally in two weeks time, as this draws a far larger field, including some of the Polos and Runxs that compete on a national level. The rally will also be included as rounds 3 and 4 of the EC championship. More info on the VW Rally 2012 can be found here.

Velvet Sky Refund

At the beginning of February I booked two very cheap tickets home to Cape Town for the weekend of the Pick n Pay Cape Argus Cycle Tour which I was set to ride. I happened to book them with Velvet Sky. I hadn’t previously flown with them, but people I had spoken said they were as good as the other low-cost airlines, and the tickets were about half the cost of the next best offer.

At the end of February newspaper reports started coming out about Velvet Sky being in a bit of trouble. Some flights were being cancelled, but then they seemed to get going again, before halting flights once more. Apparently they’ve been having a bit of financial difficulties, but they kept on assuring passengers that they’d be up and running soon. So it wasn’t till the week preceding the Argus that I get an e-mail from Velvet Sky stating that my flights have been cancelled.

They attached forms where you could apply for refunds, and I immediately filled them in and sent them back to Velvet Sky. I got tickets with another carrier and enjoyed my weekend. A few weeks later I hadn’t heard anything from Velvet Sky. So I sent them an email as they had indicated that one could expect a refund within the next month. The response I got stated that all there bank accounts were frozen, and that as soon as the court proceedings they were busy with were completed, payouts would commence. Another month later still no news.

Some time in April, Computicket refunded several million Rands worth of tickets to passengers whose flights were cancelled and had booked their flights through Computicket. I had unfortunately bought my ticket direct from Velvet Sky. But there was hope.

I had read in a few newspaper articles where reporters suggested attempting a “Chargeback” process on the transaction. I’m not fully sure what it’s all about, but it boils down to that all transactions made with a credit card have the ability to be reversed if one can prove that you did not receive the product/service that you paid for. It has something to do with the new Consumer Protection Act.

I’m not going to bore you with all the details of my dealings with Absa trying to get this right, I’m just going to post the necessary data. This is the statement I got from Absa, and apparently all the banks are sticking with it.

We refer to the recent news broadcasts and speculation pertaining to Velvet Sky.

Local banks have raised their concerns regarding cardholder rights pertaining to chargebacks. Internal discussions were held and Nedbank have come to the following conclusion: Velvet sky is still in operation, as no liquidation proceedings have taken place at this stage. Should the issuers feel the need to raise chargebacks for services not rendered they will be required to supply all of the following documentation to validate the chargebacks raised.

The documentation must consist of the following:

•             A cardholder letter.

•             Proof that the cardholder attempted to obtain a refund from the merchant but failed (a reference number for the call or an email from Velvet Sky confirming a request for refund submitted).

•             Ticket or booking confirmation of the scheduled flight that supposedly did not take place.

Please take note of the following :

•             Chargebacks may only be raised after the expected date of service has lapsed.

•             Return flights: only a partial amount will be accepted for the leg of the flight which did not take place.

If all of the above conditions have not been met, Nedbank will re-present the chargeback as invalid supporting documentation supplied.  Each case will be reviewed to validate whether it meets all of the above requirements.

I was slightly worried because I didn’t have any proof that Velvet Sky actually received my specific forms. I assumed they did, because I e-mailed them, but they did not reply or give any reference numbers. So I decided to just give them everything I had.

I created a folder dedicated to this process. I wrote out a full letter explaining when I purchased the cards, when I received cancellation emails, when I applied for refunds, everything I had that involved communication with them I listed. I also attached pdfs of every e-mail I sent them and every form I had filled in. I also mentioned occasions when I had phoned Velvet Sky.

Last week Friday after several backwards and forwards emails, I had compiled all this data and sent it in to disputes@absa.coo.za (the official e-mail for card disputes). Today (4 working days later) I got an e-mail from Absa saying that I had been refunded the full amount.

They do note however that

the merchant bank has 60 days (local merchant) and 45 days (international merchant) to respond.

If the merchant bank presents the transaction and provides us with the necessary documents, your account will be debited with the amount concerned. In event of the above, we will let you know and provide you with the documents concerned.

Velvet Sky didn’t give me the service, and haven’t paid me a refund, so I don’t see how this will happen.

So in the end I got my money back :) I was adequately satisfied with the e-mail communication with Absa, and will admit that I was quite surprised that I got my chargeback so soon after applying for it. Note that you must apply for an Absa charge back within 120 days of the failed service. Other banks may have shorter or longer periods.

An Achieveing Weekend

Last year was the first time I really got some experience in embedded programming. I’ve subscribed to Hack a Day‘s RSS feeds for the past few years, so a source of ideas and motivation is never lacking. I bought an Arduino to play with a few years ago, but obviously I wanted to get to a point where I didn’t need an Arduino for each project I work on.

Last year I took an Electronic Design course (most frustrating and enjoyable subject I’ve ever taken) in which we were introduced to the Renesas family of microcontrollers. Specifically we used an R8C mounted on a breakout board for ease of use. Through the course we got to play with LCD screens, Serial and I2C communication, communicating with motor drivers and some other useful bits and pieces. We were also taught about registers, interrupts and some other important aspects of design.

The Renesas would then have been the obvious place to start on my own projects, but the chips need a Renesas specific programmer that costs upwards of R1000, so I never took it any further. However, back in 2010 of Hack a Day did a great 4 part tutorial in getting up and running with the Atmel AVR range of microprocessors which I had bookmarked with the intention of one day delving into. The benefit of these is that an ordinary Arduino can be used to program them.

Over the past year or two I’ve also ended up picking up a couple odds and ends which have just been lying around since their acquisition, one of which was a Sure Electronics 24×16 LCD grid. So end of last year I finally get round to ordering some proto board, a few sockets and microcontrollers.

Now several months later I’ve finally got round to putting some stuff together. Conway’s Game of Life has always interested me, with it’s simple rules, it’s fairly straightforward to program. A grid of LEDs seemed like the perfect place to give it a run.

I visited quite a few websites in my search to get some code for this display. The display runs on an HT1632C driver, and somewhere along the line I came across a library to make it work, and some accompanying Arduino code. The library has the comment

in it, and the Arduino code

By Joel Simon, Based off LED Pong Clock by Nick Hall

I’ll update with links as soon as I figure out where exactly I sourced them. After getting it running nicely on the Arduino I set about adapting the code to run from one of my Atmega168PA microcontrollers that I’d required.

This first required a bunch of work getting avrdude and winavr up and running, all thanks to scszy’s tutorial and references. But after that it was fairly straightforward. I started off by programming my Conway’s game of life, which after a while I got running quite nicely. At the moment there is an option to manually specify a starting grid in code, but I just let it run by randomly generating a field and running from there.

After that was going I hooked up a MCP9701T-E/LT thermistor to an analogue input. The specs aren’t great, and nor is the performance, but I was at least slightly chuffed with my soldering of this SMD component onto my proto-board. I was quite surprised to see how quickly and how varied the readings from this unit are. I still need to get a proper thermometer to do some type of calibrating, but readings change several times a second one and half degrees up and down. This might be due more to voltage supply, but I haven’t investigated much.

I then proceeded with a push button so I can have a bit of input. My intention is to eventually have this with four different screens to choose from. The first one with the time and temperature. I want to see how accurately I can work off one of the built in clocks, as the microcontroller doesn’t have an RTC. I’ve also got a GPS unit lying around which I want to try to connect so as to be able to update the time every now and then.

The second menu will display the day and date. I have a stationary bike and a Polar heart rate monitor unit that I want to give a try as well. I’ll grab a reed switch and a magnet to put on the back wheel of my bike as a second speedometer and try get my RMCM01 Polar OEM which is a SparkFun product (Sparkfun apparently no longer sell the RMCM01 individually, but it can be bought ready to go) I sourced from Netram. These will displayed when active on the third menu. And the fourth menu is my Conway’s Game of Life. And I want to build some kind of housing for it, even if it’s just a nice perspex front.

I’ve done a mockup so far which can be seen in the video below:

I’ll do a new post with source and schematics at a later stage once I have the rest of the thing setup and working nicely. I just posted this now because I haven’t written anything in a while and I felt like it.

I’ve also reaffirmed my knowledge that I get far more work done at night, as most of this was accomplished between 23:00 and 04:00 on Friday and Saturday. I think there’re just less distractions.

Merrell Tsitsikamma MTB Challenge 2012

EDIT: apparently lots of people are looking for results, you can find them here.

With the prospect of doing the Dr Evil Classic in September this year, I decided the best way to be ready for it would be to try maintain and improve on the fitness level I had for this year’s Argus. So a while ago I heard about the Tsitsikamma MTB Challenge. The race takes place just down the road and I managed to get a friend on board too.

We opted to give the 72km ‘marathon’ route a go and camp there the night before. So 6 o’clock on Friday evening, three of us headed off to the camping ground. The base for the event was at the Tsitsikamma Adventure Falls. When we got there we went to registration and were told we can just camp wherever we could find a spot.

at least there was a pretty view to start the day

This turned out trickier than expected, and none of us were quite sure where they were going to fit in the 300 campsites advertised. It seems like only 20 or so groups were camping so we found a spot and got the tent up. Then we were woken up at 4:30 the next morning with people packing for the water points. Not ideal, but besides that, the rest of the event was great.

The race started at 7:30 with the 72km riders and was followed shortly by the shorter 42 and 23km rides. First 10km were all jeep track that lead up to several short single track sections through dips and some water. This is where a few of the top 42km riders caught up to us. Some more jeep track and we were at the first water point where the 23km route turned off. The next water point was only at the 40km mark, after some decent ups and downs. The water point here even offered a welcome beer to those so inclined.

10km on was the next water point shortly after which we crossed under the N2 and headed off up the hills. This was one point where there were cyclists riding in both directions. The marshalls did well to separate everyone though. A bit of a stretch next to the N2 and the final ‘major’ hill lead us up to the last water point. Down the other side, a little bit of single track back under the N2 and we were on the home stretch.

‘low gear’? More like no gear :(

From here we did a bit of a loop back around to the start point where we finished shortly after 11:30. A shower and some food later lead to the prize giving. Quick packup and it was on the road back home.

Results aren’t out yet, but we reckon we did somewhere around 4hr15min (edit: 4hr12m22s was the official time). I was quite chuffed with this, but when compared to the winning time of 2hr31min, it may not seem like as much of an achievement.

Overall it was a really fun ride. There wasn’t as much technical or single track as I would have liked, although it can lead to frustration when getting stuck behind someone or holding other people up. The route was well marked, and there were only one or two points where we were slightly unsure whether we were on the right road. Not the toughest 72km I’ve done, but a really nice ride through a stunning area.

Thanks to Merrell and the other sponsors for a great event, look forward to doing it again next year with any other events they have planned.

Also, my bike was amazing. 15 year old Giant Iguana is still going strong. I need to do some work on it, but it got me through the day, even with the tyre delaminating slightly. The three of us were also very fortunate with a complete lack of punctures over the entire route.
