content: I will be at the dunstable downs radio rally again this year with a load of crap to sell / give away, is anyone else going from here?http://www.ddrcbootsale.org/index.htmIt's on Sunday May 21st, but it's most active in the morning. There's parking, refreshments, plenty to see and buy so it can make a fun day out if your interested.previous threads:https://www.eevblog.com/forum/buysellwanted/dunstable-downs-car-boot-sale-discussion-thread/https://www.eevblog.com/forum/buysellwanted/(uk)-dunstable-downs-car-boot-2016/

content: Quote from: SingedFingers on March 24, 2017, 10:59:23 amI didn't know that was still going - not been for a while - is it any good?Problem with most rallies that are/were at "proper" venues is that the stall fees tend to be too high to attract people clearing out stuff, so it's just traders. That's certainly what killled Pickett's Lock.Most decent rallies died out years ago - Dunstable Downs is the only one I bother with these days- being held in a field means it's still cheap enough to attract people clearing stuff out, which is where the bargains are.

content: To be honest I haven't been to a rally since the 1990s and that was the one at Pickett's Lock just as it descended into traders. There was another one out in the sticks near Harlow as well. Long gone is the "electronic jumble sale" which I loved. This is a somewhat new resurgence in activity in this space from me really after a gap between 2002 and 2015. I'm only 10 mins away from it in the car so it's no wasted effort really.However, in context, I'm older, considerably less poor and more objective than before so I'm not really after bargains and boxes of junk now.

content: Quote from: mikeselectricstuff on March 24, 2017, 11:06:56 amI think Kempton is worth going to occasionally, particularly since Dunstable is further away. Last two times there were sufficient fleas stalls to make it interesting.An advantage of Kempton is that there is power, so you can see equipment working before buying it. (And it isn't weather dependent, of course!)

I've picked up some nice stuff at each, e.g.Kempton: Solartron 7075 DVM for £40 (didn't bother with a broken HP1740A for £5, since I hadn't yet succumbed to TEA and allied syndromes)Dunstable: new DC-18GHz 0-70dB in 1dB steps attenuator for £30I wonder if we will recognise each other. The only identifiable picture of me that I have posted on social media is with a new-fangled Harrier in the background (or was it a P1127?)

content: The last few Pickett's Lock events were certainly less interesting than earlier years. But I think what actually killed it off was the redevelopment of the sports hall into some part of the olympic stadium.BATC rally used to be good - previously near Grantham, then Coventry. Not sure where now.I still go to St Neots rally (just off the A1) - it seems to grow and shrink but can still be worthwhile if the weather's good enough to go outside.RATS rally (Rugby) was a good one too, but haven't been for a while and not sure where it's held these days.

The testgear has included Racal counters, Marconi Sig-gens and lots of smaller bits like connectors.But I am starting to realise the depth of my testgear addiction and have recently had a table at Kempton to sell stuff for a change and reduce the "heap". It has worked well and I'll be there in a couple of weeks. The mains power means I can demo stuff which is best for both parties. I'm the chap with a green message fan on the stall!

content: Scored an Anritsu 8810B radio comms test set for £60, and it all seems to work (Not too shabby for a 300K - 3GHz SA plus power meter and sig gen).It has the usual problem with poor contrast on the screen that most of these seem to suffer from, and I have the eternal problem of finding that the set of inter series adapters I own is not quite as comprehensive as I thought it was (I am missing some TNC to sma or BNC).....First job however, disk image of the PCMCIA ATA flash card.... They seem to be a little flaky by reputation.Annoying when the adaptors are likely to cost more then the instrument did, but I cannot bring myself to use the unbranded specials on measuring instruments because so many of them are horrible once you get above nearly DC.Lots of bench power supplies there, and a surprisingly good general selection of test gear.Also, does anyone have the pinout for a Marconi 6960 sensor cable, I managed to get the meter and a power head that allegedly works, but no cable and the information is surprisingly hard to find. I am pretty sure the connector is a Binder M16, 12 pin job, but what is the wiring?Regards, Dan.

content: I did rather well on that Anritsu, but that was Kempton, not DD (And was a very good deal), and those attenuators (If they are the blue ones with the two brass wheels) were indeed rather tasty (I snagged two at DD last year, a guy can never have too many variable attenuators in the lab).I did not go out looking for a rad com test set, and expected it to be silly money but asked anyway, but the guy who had it had just had a hernia op and wanted rid, Anritsu not being the lightest of gear (Actually my older and physically smaller MS2621B SA is very much heavier, CRT Vs LCD, where do they get the neutronium for the chassis?).See you guys Sunday, I am the fat guy with glasses and the beard probably wearing a Chaos Computer Club teeshirt.Regards, Dan.

content: I should set up a stall to sell thermal cameras....... a concentration of different thermal cameras never seen before, or likely againSadly from what I have been told, I would have to tolerate people offering me £20 for a high spec working thermal camera ! My brother used to sell a lot of militaria at car boot sales but he says the world has changed. Punters appear to want everything for nothing rather than paying a price fair to both buyer and seller.Sure there are bargains to be had as some sellers just want rid of bulky and heavy kit. It is the buyers who want to really screw the seller down that concern me. I have always happily negotiated with sellers and always ensured that we were both happy with the final price. I just do not think selling at a car boot sale or rally would suit me.My 'junk' tends to get given away to worthy recipients that I know. I am currently fully equipping a good neighbour's spare room as a fully fledged electronics workshop and lab. lots of excess quality test kit of mine going into that. All at no charge to him. I hope I am a generous person but I object to people expecting me to sell good kit for a song just because they do not want to pay more for it.Fraser

Some big old Farnell power supplies in need of repair that I'll be happy to take very little money for just to move them on.I'm slowly creating enough room in the house to play with some serious mechanical stuff.

content: I have just got home from a busy day that thankfully included visiting the Dunstable Rally.It was a brief 'fly-by' to rendezvous with Mike so I did not get to walk around all the stalls but they still looked well stocked at 11:00 when I arrived. There were also plenty of punters, but whether they were spending or not, I do not know.It was a good day for my thermal camera collection....three more cameras added..... another Military type, an AUTOLIV FLIR Audi night-vision and the FIRE FLIR that Mike did a video about. I was so chuffed to see his FIRE FLIR for sale and it took about 5 seconds to decide to buy it .... that was how long it took for me to register the price label on it !They are quite rare, so for a collector it is a bit of a 'find'. Not the most ergonomic to hand hold thoughI got lucky on that camera as someone was haggling with Mike on price when I saw it and they decided to wait to see if Mike would lower his price at 12:00. 'He who hesitates is lost' and all thatBy the same token, I missed out on buying some nice looking stereo close up binoculars that Mike had. I just did not see them soon enough.

content: Yes, it was a good morning although I resisted the urge to buy more junk - possibly too well in the case of one item. Decent number of stalls as wellIt was also good to put some faces to names.Annoyed, however, to have only spotted the second average speed camera on the way in on the A1081, plus thought it was a 60MPH limit along there but realised on the way home that it's 50MPH. Hmmph, it might turn out to have been an expensive trip even though I didn't buy much.

content: Hiya,No urgent plans for it. I have a good knowledge of the camera on which the Autoliv is based, so may have a poke around to see where the common design points start and finish. I have the original controller as well, but to be honest, I know that this part is not essential for camera operationThe lens and microbolometer related stages are what I am interested in at the moment. There will likely be no magic fix for the Autoliv cameras as they were designed to be a pig to transplantI now have one to experiment with and it has not cost me the big money that is being asked on ebay, so I am happyFraser

content: Just finished unloading the few bits that didn't sell. Was good to meet a few of you, even if only briefly. I had a decent day, got rid of loads of stuff, though did curse when I realized I'd left my big box of RF attenuators at home.Thanks to those that kept an eye on my stall for a bit whilst I took a comfort break.

content: Quote from: Fraser on May 21, 2017, 04:45:15 pmLet me know if you need any help with the experiments or a cross-check. I've only dumped the SPI flash so far, it contains the FPGA bitstream obviously, some unknown soft-core MCU firmware that listens to CAN and I guess NUC tables have to be there as well.I was planning to do more reverse engineering, but as I remember you've mentioned in other threads that ROIC can brick itself if it detects tampering. So I was thinking that making various interposer boards (between Autoliv boards, between the main board and ROIC etc) with the Tek logic analyzer probe landing pads would be a good way to go first - just listen to all the signals and poke CAN only with ROIC disconnected.In the end it is a lot of work and in the meantime I bought Thermal Expert Q1 Plus that satisfies all my thermal camera needs (mostly electronics repair) so the Autoliv camera will have to wait.

content: Hiya LukierROIC is safe, it is dumb. The security surrounds the FPGA I understand. As you know, if the FPGA is disabled by a defensive measure, the unit becomes scrap. I understand the camera operates in a challenge and response manner where the FPGA asks for some unique data, when it receives it, the FPGA effectively 'unlocks'. If the expected data response is not received, i.e. no data response, the FPGA will not 'unlock' but neither will it brick. If the challenge is met with 'illegal' data as a response the camera records a 'strike'. IIRC after a certain number of 'strikes' occur the FPGA permanently locks , never to 'unlock' again. In truth the FPGA just needs its configuration firmware to be replaced. If a strike is recorded but then a valid data set, the strike count goes to zero again. This is done because data errors can occur due to an issue elsewhere on the CAN bus.This information is correct for another 'secured' camera that I have worked on. I believe it is also the most likely MO for the Autoliv camera, but that is not confirmed by me.The good news, and reason I wanted the camera, is the microbolometer and thermal lens are standard parts that I can make use of even if the FPGA is locked. There is also the possibility of putting a new firmware into the camera if one that I have in a similar camera is compatible.Fraser

content: Good to meet a few of the locals, and spend more then I should have...Best score of the day for me was a Korg MS-20 for £70, it needs some minor fettling (A replacement key, and from the sound there is a dry electrolytic in the power supply somewhere, no biggie), also wants a bit of a stripdown and clean but is clearly working, not my usual sort of rally gleaning but too good to pass up.The old synth market is **INSANE**, no way should these be worth what they are selling for, still, whatever folks want to pay I guess.I shall have fun tarting it up, then move it on, should easily pay for the rally (and Kempton too).Regards, Dan,.

content: I too missed KJDS.Of my stuff I didn't really expect to sell the "decent stuff" because I wasn't prepared to drop prices too much. OTOH I did sell more than I expected of my "tat" (e.g. not very nice and/or and partially functioning DMMs, CATV amp), because it was in the "pocket money" price range. That seems to be the flavour: pocket-money car boot sale.My attitude of paying £7 (£10 - £3) for a pitch worked out: I sold more than that and didn't have to walk.Unfortunately I also "blew" the profits on another of those "rather tasty" 0-69dB attenuators that I picked up last year; I suspect the vendor has more as well.

As a rally venue it is OK, nothing more. The rally (the last time I went) was also only a shade above OK.

content: Quote from: CJay on May 23, 2017, 05:29:53 amRed Rose used to be OK but the last time I went to the winter one it was carp so haven't bothered since.I last went to the Norbreck rally in 2012, I think. Judging by the recent tripadvisor comments the hotel has just continued to decay since then - and it was already at a low ebb 5 years ago. I didn't go back which was about 40% down to the rally which was a bit "meh" and 60% down to the venue.Rugby was good the last time I went but they have a habit of holding it when I'm on holiday so haven't been in a few years and will miss this year as well.Telford was "small but interesting" when I visited a couple of years ago and I plan to go this year if possible. Hack Green even smaller but also interesting (more ex military stuff). South Gloucestershire was OK but I don't think that it has run recently, Newbury is usually good, McMichael - only went once & wasn't impressed but I think it was just a bad year and I always meant to try it again. Milton Keynes utter carp the one time that I visited & I haven't been back. Wythall was OKish but I have missed the last 2 years.The daddy of the Midlands rallies was, of course, Elvaston Castle, which very sadly closed its doors in 2008 -http://www.nharg.org.uk/files/The%20Elvaston%20Castle%20Radio%20Rally%20-%20all%20good%20things.pdf

content: I used to go to Longleat, Pickets Lock and somewhere in Wales, I forget where. They were huge events with masses of sellers stalls and a really good day out for a techie. I had not been to a Radio Rally for more than a decade before visiting Dunstable. In comparison to the previously mentioned, Dunstable appeared very 'compact'. As a student I worked in an electronics emporium and we went to such events to sell discrete components, Hameg scopes, C-Scope metal detectors etc. Those were the daysFraser

content: All on the list, thanks guys.I managed to get to Hack Green and Telford last year, both tiny but interesting, Telford will be, I think, larger this year as it's got the GQRP convention as well. I'll be at Telford again this year so if you fancy a delicious cup of indeterminate brown hot liquid feel free to say hi...The other local ones, Red Rose being the nearest, are all up for visits now.Newark sounds really interesting, that's 'in range'.The rallies I've been to were a shadow of the ones I remember (Bolton, Southport, Norbreck, Manchester) but to be fair to them, I hadn't visited those ones before last year though we did make an abortive attempt to get to Telford ( turned out the navigator had no idea where Telford was and it was *long* before SatNav was a thing).

content: had a pretty successful day at Dunstable on Sunday, didn't get a chance to do much wandering around to see anyone though. It was a busy time all day, we left just before 3pm as i hat to get back to see Brian Cox at the Manchester Arena, yes just 24 hours before last nights appalling attack.We did see Mike fly past at some point in some kind of 'high speed scanning for bargains' modeThe good news though, is i didn't buy a thing!i think next time we should all arrange to meet at a particular time?
