If trying to use a satnav to find Darley Moor please note the circuit itself doesn't have an actual postcode. The nearest postcode to the circuit entrance is DE6 2GT; the nearest postcode on the A515 is DE6 2ET. As neither of these will get you to the actual circuit entrance you may be better off using a grid reference:

Camping is available at Darley Moor on the Sat eve. For anyone wanting to camp, the gates will be closed (but not locked). Just let yourself in (but please close the gates behind you) and park in the comeptitors car park (up near the toilets). Price is £5 per pitch per night. I'll collect camping fees off people either tentside or at race sign-on on the Sunday. Its very basic facilities (grass, toilets drinking water and fresh air) |

Shawn can't make it. If anyone of similar stature would like to ride Notso, can still bring it. ------------- jdub... Got the T-shirt http://protobikes.org.uk/ https://www.flickr.com/photos/150386999@N02/ |

Hi Jonathan - Just had a call from somebody from Global Cycling Network - They want to come along and film at Darley Moor and are looking for a recumbent to ride to show a comparison with upwrong bikes... The chap is 5ft 9!! :D ------------- |

I can loan the Nocom (perfect for 5'9") if someone can pick it up from Manchester and look after it for a week - unfortunately I'm in St Ives for the Leicester/Darley Moor weekend. Might be a bit tricky for a first timer mind... I suspect it'll be one of the new chaps: https://www.youtube.com/watch?v=AV8mAKZFA8E" rel="nofollow - https://www.youtube.com/watch?v=AV8mAKZFA8E Russ

| I think the timing system or my tag had a meltdown on my lap 2. I know I was going slow but to take 17:27 to complete a lap is taking the Michael. I was probably behind James/Jeff/Graham. |

Ah, didn't spot that one. We had several people with spates of missed reads for some reason, and have had to do some extrapolation. Give me a few minutes to fix it... ETA: Fixed (or at least bodged), hopefully. |

On a hunch that the timing problems at Darley Moor were due to only reading tags properly on one of the aerials (backed up by Andrew S informing me that he'd tended to pass on the right of the track - and got almost no reads - while I was passing on the left and was picked up without problems), Natalya and I have done some testing this evening... We've reproduced the problem, which turns out to be one of extremely reduced sensitivity rather than complete non-functionality (making it difficult to spot trackside), and traced it to the long coaxial cable. This clearly better than a fault with the RFID reader or the aerials, and IMHO preferable to failing to find a fault. (I've just noticed that this topic has the wrong year in it.) |

Thank you Kim and Natalya for the investigation! It is great to know that the issue is understood :) And thank you also for the guesswork to get the results out despite the fault :) |

Well done Kim & Natalya. Impressive detective skills there. Could try and find a better quality coaxial cable I guess. Does it get ridden over? Roy

Just standard troubleshooting. First try to reproduce the problem, then swap things around to see where it goes. The interesting thing is that there appears to be a compatible tag lurking somewhere in (or within a few metres of) the front half of our house. I know the EPC, but not where it is or what it might be attached to (no, not my helmet). Didn't quite get bored enough to turn the gain down and wander around with an aerial to try to locate it... :) And yes, the cable is the long one that gets ridden over. Which rules out most of the ready-made cables with suitable connectors on them, which tend to be the diameter of a thumb. Not sure if that's what's caused the problem or not - the cable seems fine when tested at DC with a multimeter, so my guess would be water wicking up the dielectric and wrecking its RF properties. Andrew and I will do some digging... |

I once cut our internet off when I moved a chair in the hall and did not notice I'd put the leg on the cable. (it is one people sat on when they were making land line phone calls) Yes water can cause a lot of weird problems for electronics. When we first moved into the farm the house electrics kept tripping for no obvious reason. Turned out to be the wire to the electric pond pump had water in it. The pump worked fine though. Just kept tripping the circuit breaker at random intervals! I'll be back on the track probably in October. (I'm going to Scotland in September unfortunately) Not sure if I'll be on a bike in my latest Strava photos though. All the best. Roy

I'm just wondering if the cable can be suspended above the riders? It wouldn't have to be raised very high, even the upwrongs don't need that much clearance. It's a thought. Roy

It turns out the cable that failed was one of the old ones that came with the timing kit, not one of the slightly beefier ones bought since. Hence it is of unknown age and provenance and probably well due for retirement. I'm not sure I would have relished riding under a dangling cable in last Saturday's gale, even if anyone had remembered to bring the necessary gantries and guy ropes required to suspend the thing. The cables are pretty robust and if one or two need replacing every few years then it's a reasonable price to pay.

The BPCC were taking this approach for the Shenington 24 hour race, with a gantry above the track with traffic lights mounted on it, as well as various cables. Seems to me that while that's perhaps the ideal solution, it has the fundamental problem that to do it safely requires a structure that takes time to build and strike, and is going to be awkward to transport (even if you're just stringing a caternary wire between two poles, you need poles and weighted bases). You also need even longer cables, to account for the extra vertical distance. A simpler (FCVO simpler) approach would be to have a second RFID reader on the far side of the track, and either use a dirt-cheap cat5 cable to connect to it, or use WiFi and a suitably beefy battery. The system supports this, though I'm not sure I'd want to... I'd suggest that the current approach and considering the across-track cable to be a wear item is probably more sensible. It might even be worth keeping a spare in reserve? Incidentally, I found this nick in the insulation:  Wasn't easy to photograph, but I can see copper inside. That'll do it for water ingress.

Is there a rental car near as they use them to log when they come and go into a depot?

Entirely possible, the system certainly has enough range to reach the road outside. Actually, my Co-Wheels membership card is RFID, maybe it's that? I'll have to try it next time the system's set up. Another likely suspect is the proliferation of miscellaneous previously-loved computer equipment. |

Random thoughts on this: 1) While it would have been interesting to see his performance on his DF bike, it would have muddied the issue they were trying to demonstrate by introducing familiarity and training variables. I'm sure he'd have sailed round the hairpin on it compared to any of the other machines. 2) Pleased that my time was faster than he managed on the Raptobike :) 3) It was a shame that they didn't show more of the BHPC racing in general, but it wasn't a particularly exciting race, and the size of the Darley Moor track means it's hard to get good footage with a single camera. I expect the weather was an additional constraint. 4) While I'd have liked to have seen more of the variety of machines (the tandem barely featured, for example), I suppose the emphasis fits the aerodynamics narrative. (And means we didn't come across as too correx-beards-and-gaffer-tape for their core audience: Well done David for looking the part.) 5) Spot-the-technical-inaccuracy... 6) Comedy subtitles. Someone who doesn't know what a fairing is has obviously gone to the effort to time them properly. My Streetmachine weighs 24kg, does that make it a fully-fed recumbent bicycle? :) One of the Youtube comments suggests that they follow up with an item about riding recumbents on-road. That sounds like an excellent idea - could segue past the usual safety and climbing ability discussions into the comfort, accessibility and fun reasons that most of us actually ride recumbents for in the real world. Anyway, thanks to Barney and co for making this possible. |

Don't want to sound naggy, but it looks like the championship tables have not been updated yet, I keep checking on an almost daily basis and just wondered if it may have been overlooked, thanks, lee. ------------- Current fleet: Milan SL MK2 #027, Fujin SL II, Beany! |

The GCN recumbent video was excellent. Well done to Barney who I thought spoke clearly, and gave good instructions. A bit of a TV talent coming out there. The program left plenty of room for a part 2. Well done to GCN and all the BHPC folks involved in making this happen. |

Cracking GCN video, well done Barney and all involved, sorry I couldn’t have be there. It came across very well, well shot in difficult conditions and well edited and mostly a positive spin on what could have been edited in a very different way. It’ll be interesting to see if it results in a higher attendance at the next races. Andrew has there been any increase in website traffic? Russ |

Has anyone seen the latest video from GCN Tech in which two of their presenters spend several minutes discussing the pros and cons of recumbents, although neither of them have riden one? Perhaps we should invite them along to one of our meetings to "put their pedals where their mouths are" ! Stuart ------------- Laid Back in Spirit |

Having tested the shiny new 15m recumbent-resistant coax cable obtained by Andrew S (unsurprisingly, it works fine), I had a go at this: It turns out that Decathlon products use Impinj-compatible tags, and I was detecting a) a tub of electrolyte tablets and b) an unopened packet of insoles, depending on which way the antenna was pointing. (And the tags are locked so you can't re-write them to spell rude words in hexadecimal and/or sneak an RFID reader into the shop and put lots of shiny things through the till as pot noodles.) |
