  1. How many of you Hak5 supporters are only running Windows OS? How many of you Hak5 supporters are only running a GNU/Linux OS? How many of you Hak5 supporters are wannabe hackers? How many of you Hak5 supporters are hackers? Gerard
  2. Probably on the attic i will still have laying around a Vic-20, and a hole lot of other stuf from the days way back then. Gerard
  3. Hello its me. (Way back when,) (Also some time a go) (made when placeing the sign) (most resent) Gerard (iam born on 29-06-1959 , first computer: Vic-20, played back in the days with arpanet, so yes i'am around 4 a long time now )
  4. May i ask how many people turned op ad the first Euro meeting ? Gerard
  5. Finally got the electric part done. And all so got my hands on a brand new PMR (basestation) radio so maybe if all is going along to day with out any problems, i can work to get the PMR internet Gateway (FRN) back online. :roll: Gerard
  6. Wel the concrete is bin made and poured add the base and is dry out so i layed back the pavement stones. http://www.w-p-k.org/picture_library/straat-weer-dicht.png[/img] Next up is finnising the electrics. Gerard
  7. http://www.w-p-k.org/picture_library/april_desktop.png[/img] Gerard
  8. With just only laptops and PDAs connections from just over 1,5 KM has bin made with (out any extra antenna connection to the laptop or pda) on the Fon router (thats connected to the 2x16 sloted waveguide omni) add the top of the mast/tower. The small prime focus dish connects to a downlink point just over 8KM away (non L.O.S) With de big prime focus (homemade)dish connections from more than 15 KM has bin made but is now connecting to a realy hard to connect to (non L.O.S) downlink point just over 8KM away. +/- 1/3 of the downstream (and thats 20mbit per (7)ADSL and (1)Cable line(s))
  9. The hand winch is mounted. http://www.w-p-k.org/picture_library/lier.png[/img] All thats left to do is some electrics and making and pouring some extra concrete for de base. Gerard
  10. Yes and nope we are in a small (Dutch)village (in the north of the Netherlands ) very close to the German border. For load balance we make use of a Coyote Point Equalizer E550si Load Balancer By the Way finest all the welding of the neck to day http://www.w-p-k.org/picture_library/kraag-klaar.jpg[/img] Next op is the building and mounting of the hand (non electrical) stealcable winch (pulling power of 2000 kilograms) Gerard
  11. Iam the one that designed this antenne mast/tower setup, but it is the Wireless-(WiFi) -Community members that made it a (still on going) community project. Gerard
  12. Iam the founder of this Wireless (WiFi) community, And i share all my 8 (20mbit) internet connection (1 cable and 7 ADSL) lines with anyone that can acces this WiFi network. Add this moment all the 53 membrs/users of the Wireless (WiFi) community got a free internet acces. And we/i make use of all the WiFi hardware AP's and Routers that we/i can lay our hands on so we /i can ceep this wireless community up and running. Gerard

  14. part-4 The next rebuilding step is reinforcing the antenna pole foot setting for exsta strengthening of the antenna pole. (this will take the better have off to day) http://www.wireless-emmercompascuum.nl/picture_library/mastvoet.png[/img] But the Fon-router (at the top of the antenna pole connected to a 2x16 sloted waveguide omni) and all the uplinks and downlinks are back online and in working order http://www.w-p-k.org/picture_library/hij_staat-2.png[/img] Gerard
  15. Part-3 http://www.w-p-k.org/picture_library/bijna_recht.png[/img] http://www.w-p-k.org/picture_library/recht_op.png[/img] Tomorrow still the rotor controls need to be connected to the rotors and the next step is getting all the uplinks back on/inline (replacemend of the PMR-radio has still to be ordered for the PMR gateway). Gerard
  16. Part-2 http://www.w-p-k.org/picture_library/voorwerk-2.png[/img] The beginning is there. And if gods willing to continue to keep this fine weather (no rain and wind) work will be going on 2. Gerard
  17. Part-1 As the users of the social W-Ecc WiFi iternet (free)acces network already knew, very resent the antenna pole got a considerable lighting and wind damage. The damage to the roof and the WiFi antenna's is where very small to nothing Almost all in and electronica present to the antenna pole has survives (AP's still in working order only the PMR Internet gateway radio is dead). So the lighting protection grounding of the antenna pole turnt out to be not voor nothing. http://www.wireless-emmercompascuum.nl/picture_library/mast-inslag.jpg[/img] The lighting took a away a 3 cm piece of metal ad one side of the antenna pole. What resulted in bending the antenna pole. My neighbours told me that it went boem, fire work and next the antenna pole slowly but steadily went down untill it reached the roof. Fortunately for the users of the social W-ECC network we possessed the backup Wifi network hardware at the support points, with the result a lot of users of social network still achieved a Internet connection. One of the users (and sponsor) of the social W-Ecc network offered a replacing antenna pole and provided it directly to my doorstep. http://www.wireless-emmercompascuum.nl/picture_library/mast.png[/img] In the comming period a number of W-ECC social network members will be very active with rebuilding/replaceing the antenna pole. Will keep you all informed of this progress Gerard
  18. With out any word's! Gerard
  19. And finally for allthatis some intrest in the radiation pattern of this antenna, it looks like this: Gerard
  20. The Build of the 3 (AMOS) Sector antenna's for the WirelessPowerKamp Here some picture's of the build. What brings it too this. Next is fitting the "radome" protection on the antenna' (the iron parts is for mounting the antanna's) And the final mounting of the antenna's must be something like this: (Again with a big thanks to Pe2eR) Next up is building a butget all weater caseing for mounting in the La Fonera's with out to have to take the La Fonera's apart, but still with a external antenna mouning point and a P.O.E (Power Over Ethernet) feeding. Will follow up with this project some time soon. In the mean time just have fun in your live. Gerard
  21. On this page you will find information on how Pe2eR builds a sector antenna for de Wifi 2,4GHz ISM band. The design was published by Dragoslav Dobri?i?, YU1AW. Most of his work is in Serbian, but Dragoslav and Pe2eR have corresponded in English. they differ a little about the dimensions of Dragoslav AMOS antenna. When Pe2eR build the antenna as Dragoslav describes, it usually has best VSWR below the Wifi band, so Pe2eR shortened it a little. So now this antenna is suitable for use in Computer Radio LANs conforming to the IEEE 802.11b/g standard – better known as Wifi. It can be used on an a La fonera Router or Wifi client with equal benefits. The properties Frequency: 2,4 to 2,5GHz Impedance: 50 Ohm @ 2,45GHz VSWR: < 1:1,5 Polarisatie: Verticaal Gain: 11dBi Vertical beamwidth: (-3dB) 15º Horizontal beamwidth: (-3dB) 125º Connector: Female-N type (50 Ohm) Principe The antenna is a centre-fed broadside array antenna, based on the Franklin Antenna as published in Rothammels Antennebuch (shown below) This is the complete design in Serbian as published by YU1AW: Amos.zip (3,7MB) This is my version of his design. Overall, the dimensions are a little shorter: Construction drawing in Windows Metafile format (best viewed with Win XP fax and image viewer) Construction drawing in Autocad format Building the antenna step-by-step. Make a hardcopy of the Autocad drawing (the antenna is drawn to scale 1:1). Use 292.2mm of approximately 1.8mm diameter copper wire for each radiator. Stretch wire (to straighten it). This wire is commonly used in Dutch house wiring. Put the wire along the linear scale on the drawing and mark it as shown (I use a permanent CD-ROM marker) Next, prepare 4 pieces of PE studs. Use the insulator from RG-213 – like cable. Each stud is 15mm long. Drill a 2mm hole 10mm from the end. For the reflector, use 495x62mm of Copper-clad circuit board. Copper side must be on the same side as the radiator (Pe2eR used double-sided PCB). Drill a hole in the center to accept your N-Type connector. Pe2eR used one that comes with rigid coax attached. The shield of the coax should extend to 28mm above the surface of the PCB. The centre conductor must extend 5mm more. Drill 4 holes to attach the studs to the reflector. Bend the two radiators. Do not forget to slide on the PE studs before bending. Remember: It is the amount of wire you use that is important, not the final dimensions after bending! Fabricate the 1:4 BALUN from ½ wavelength of coax (measured by the shielding). RG-316 (v=0,697): 43mm (This is the coax cable I use here) RG-58 (v=0,66): 40,7mm CFD200 (v=0,83): 51mm “Verbindingen KORT houden” means “keep connections SHORT as possible”. Solder the radiator to the coax feed/ BALUN. Pe2eR used S-Lon 65mm mini PVC rain gutter to house the sector antenna. Pe2eR is sure that this is not available all over the world, so you need to find something similar. Pe2eR has also used this antenna without a radome. It is however very susceptible to mechanical damage. Note On the up an comming WirelessPowerKamp-2008 event, the FON WPK-network will be connected to the sector antenna's Gerard (with thanks to Pe2eR)
  22. Wel i feel nice and frendly today so if you sent me a email or PM with your email adress, name, country I will sent you a invite so you can get the La fonera router for $20,00 Yep they sending there La Fonera routers all over this eurth Yep. Gerard
