content: You could try searching 'PCB fractal antenna calculator' in google, though you wont get PCB tools per say, you will need to paint an antenna in your PCB cad sw.The reason for 'fractal' is that they are considered more compact with good gain and frequency range depending on design and the unique shape means many of them are printed on PCBs.Also take a look here:http://www.dxzone.com/catalog/Antennas/Antenna_Calculators/As for etching, I used to do this in the late 80s and beginning of the 90s, I'm not sure of your budget, but, take a look at cheap DIY Chinese milling machines. Though they may be problematic to setup and get working the first time, no more exposures and chemicals with fine traces which never have hair-line fractures and no more hand drilling of holes!!! By the time your making your 4 or fifth PCB, it cost less to have the miller cutting bare copper clad PCBs.

author: Halcyon
author_rank: Unknown
timestamp: December 12, 2016, 10:04:25 am
content: The crooks are getting crafty. Thankfully the "relay" attack has been known about for quite a number of years. Vulnerable cars are the ones with "keyless entry" where you touch the handle or push a button, the car itself initiates challenge-response authentication sequence with the nearby paired key and unlocks the doors/starts the engine. You'll find a lot of the vulnerable vehicles are in the low-to-mid range market (Nissan, Subaru, Hyundai etc...) although a lot of the Audi's were also vulnerable.Cars like Volvo and Mercedes don't seem to be vulnerable. In a Volvo the key fob is inserted into a slot or kept very close to the receiver, such as in the drivers pocket. If the car can't detect the key, it's game over, but that's assuming you were even able to get into the car in the first place. Mercedes seem to use a infrared communications system between the car and key once it's inserted into the key barrel (to get into the car, it's RF).Those vehicles which use a simple encrypted or rolling code from the key fob to the car aren't vulnerable to this type of attack either.It also relies on the vehicle owner to keep their keys fairly close to the outside of the house (where a thief can get within a fairly close range, albeit a wall separating them). You'll find many people simply leave their keys at the front door, it's probably easier to break into the house and steal the keys.

content: I don't feel like clicking on things right now, so I'm going to guess that this the same thing they were doing a few years ago, namely using a radio repeater to increase the signal strength so that the car thinks the key is nearby and unlocks. IIRC, the automakers quickly remedied that vulnerability by switching from signal strength to time-of-flight, so that they key actually has to be near the vehicle (or the thieves have to make the signal travel faster than the laws of physics allow) for it to unlock. Cars made before the switch to ToF are presumably still vulnerable—I haven't heard of any recalls to upgrade the keyless entry systems.
Dust covers for 34-pin headers? - Page 1

content: Dust covers for BNC, N, SMA, D25, D9, etc connectors are common and cheap, and most gear in my lab has protectors on any connectors that are not commonly used.Logic Analyzers on the other hand... The Tek TLA series mostly use 34 pin headers for probe connectors. The pic is what happens to these ports when the machine is left running with open sockets, in a sea-side location. (An old TLA715 given to me a while ago by a friend, who lives in Manly.)Apart from trying to work out the best way to remove salt corrosion from *lots* of recessed pins, this reminds me that my other LA's have all the probe ports unprotected too. I'd like to fix that.When I search for 'dust cap 34-pin' in the usual places, I find nothing.Does anyone know where I could buy such things? Basically a silicone rubber or plastic cap that press-fits into the slot.If not, I guess that's another thing to add to my 3D printing todo list.

I have a sticker with "10.000,000 = 10" on it.In my culture, 10.000=10000 and 10,000=10There is a buffer/amplifier available for this model. It's useful, because the signal is easyly influenced by the load, and there is no warning/indication of that on the device.

content: Quote from: Lord of nothing on November 28, 2016, 01:23:32 amDon't buy from E-Bay, if you can, build one yourself. It's honestly not a complicated thing to do.You need to figure out what sort of power you need out of it (No clue what you want) and purchase the appropriately powered LED. You can use single use batteries, like A,AA,AAA,AAA,C,D (You get the idea) batteries, throw a resistor into the mix, and wire it up to a switch. Make sure the resistor is powerful enough for your LED, and you've just made a torch.I don't personally know who sells decent ones (I've never used one, nor seen one entirely tbh) but this isn't a bad idea.

The following morning I viewed the forum as a guest so not signed in and the signature rant was clearly displayed to all, I realised then that some settings are only activated when you are actually signed in otherwise what you will see is the default forum view such as displayed to guests.

content: I would also argue you don't need to purchase everything on day one. I used the scopes from college for quite some time, it was quite convenient because I also etched the boards there back in the day. Only when the need had arisen I bought stuff myself, like a scope when I moved out of college.However not everyone has maybe a friend or local hackerspace with proper gear nearby, and certain tools like multimeter and scope are an absolute essential thing to have. But I rather buy a Rigol DS1054Z or similar bench type after waiting a few months than a budget USB scope that eventually may not work on the latest and greatest Windows or Unix like operating system, and moreover may outgrow your needs quite quickly.Nevertheless; if others are going to compile a list, IMO a fifth rule is in order: no sale prices. I saw some stuff in the video that was supposedly on sale. You can't time sales. If you want to start the hobby tomorrow you press the order button right now and maybe pay 5$ more each on that multimeter.
