Re: The 2014~2015 Operating System Thread
Main PC is 8.1 and has been since launch - wife's PC is the same.
I have a work laptop that has to run XP due to legacy software not working with anything newer (we tried XP mode on 7 and it failed to work).
Personal laptop runs 7, server-wise I have one with 2003 (Dell Poweredge 2600) and one with 2008R2 (home built Phenom-based box where all my ex-desktop bits go), a third one runs 2008 (Proliant DL380G4) and I'm in the process of deciding which one to decomission - most likely the Dell as it's the oldest and...

Re: UPS battery question
A decent UPS shouldn't deep-cycle it's batteries.
There *should* be monitoring circuitry in there to disconnect the batteries when the terminal voltage drops below a certain point.
I know that cheaper ones will deep-cycle though as I've had to replace them (complete unit - the batteries fried the charging circuit in some cases and in others it is just cheaper in labour cost/parts than swapping the batteries out for new ones).
As for upgrading the batteries to larger ones, I'd be inclined to agree with the caveats posted...Leave a comment:

Re: Nintendo DS (not DSi) not supporting WPA
I've been to a couple of "Nintendo Events" - they were for the Pokemon games...
I went with the wife so she could catch some super-rare (i.e. only available at events - e.g Mew) Pokemon - early ones used the wired connection but later ones utilised the wireless capabilities of the DS/DSi/DS Lite (IIRC more recent ones are "virtual events" over the internet via WiFi).
As far as I'm aware the Pokemon and Animal Crossing (Don't ask!) games are the...Leave a comment:

Re: Ridiculous lengths to install an OS...
It has a slot for a floppy drive but none installed - as for SATA... SAS is an option on these machines but no SATA (the CD drive is a laptop format one, I tried a couple of DVD drives in there but couldn't get it to boot from them)
This particular server is the U320 SCSI version (I plan to put the 146GB drives from the Dell in it when I have time).
It is a rack mount server, not a desktop machine

Re: How to modify the circuit to increase the range?
One thing to remember with radio transmitters is the inverse square law.
You're looking to increase the range by a factor of 7.5 so the output power (for the same received signal strength) would need to be increased by a factor of 56.25...
the BC109 can dissipate at most 300mW - so (assuming nothing else changes and there are no additional losses) your output transistor would need to be able to dissipate around 17W.
I built something similar to this as a college project many years ago (we...Leave a comment:

Re: Free wifi solution.
Easiest (though not necessarily most cost-effective) way to do this would be to have a second cable (cat-5 rather than DSL on the WAN side) router set up to serve the public side - with the right software on that router you could also throttle the bandwidth so the public users don't saturate your connection, NAT would take care of most of the security issues as long as you use a different subnet/appropriate routing rules for the two segments.
It's how I've set up connections in hotels in the past....Leave a comment:

Ridiculous lengths to install an OS...
So I finally picked up a replacement machine for the Dell Poweredge 2600 from ebay, a Gen 4 HP Proliant DL380...
It's not a massive improvement (it has a pair of 3.6GHz netburst Xeons where the Dell had 2.4's) - the big difference for me is it supports 64 bit CPU's and possibly dual-core ones.
Problem came with getting Win2k8 onto it - I have a VLK and disk but the machine only has a CD drive...
No problem you say, make a bootable USB stick - no go, I have none spare and want this machine running ASAP.
What I did do is copy the relevant... -
Re: Older OS Newer PC
I seem to recall a way around the upgrade thing on Vista... something along the lines of installing it in demo mode (without putting a key in) then reinstalling with the same media as an "upgrade" and using the upgrade key.

Re: internet
I've just remembered something about our connection...
When we originally had it moved the installer put a 6dB attenuator in the line, the original Motorola Surfboard we had didn't like it much and was unstable, once I pulled the attenuator out and connected the cable into the modem directly things settled down.
I installed the Superhub so there's still no attenuator in there.Leave a comment:

Re: internet
I've not had any problems with the wired side of the Virgin Superhub (wireless is another issue, I've taken to putting an old Belkin router in to provide WiFi here).
I'm assuming the router is in router mode and not modem mode?
Also assuming that the Cat5 wiring checks out ok?
And another assumption: you're disabling the WiFi on the laptop when connecting via Cat5? (this last one could be the source of the IP conflicts if both the WiFi card and the LAN port are somehow being assigned the same IP)Leave a comment:

Re: VHF/UHF preamp ckt doesn't work
I recall UHF being very picky about stray inductance and capacitance back when I was doing this sort of thing on a regular basis (most of my stuff was VHF/FM for audio only though I did build some UHF circuits for video/TV applications).
Are the two wires down the right-hand side of the board by design?
Also, losing the diodes was a good start, they'd have demodulated an AM signal (I've built AM receivers that consisted of just an L/C tuned circuit and a diode in the past)
Also, the cut-off frequency of the...Leave a comment:

The rubber one I have is basically a pencil but instead of a graphite core it has rubber that's impregnated with a mild abrasive.

Re: failing hdd, bad contacts?
does nobody else use PCB cleaners any more?
I have a couple still in one of my tool boxes someplace - a rubber tipped one and a fibreglass one from my prototyping days (I also have a block that's great for cleaning up the edge connectors on expansion cards and RAM modules)Leave a comment:

Re: The 2014 Operating System Thread
I'm "technically" using win2k but as I don't use it on a daily basis (I support around 50 non-internet connected machines that run it - we are in the process of migrating these to Linux or XP as they fail, the software doesn't work on anything later) I didn't select it.
As for Vista, that went the same way as "Me" on any system I find it on (immediate upgrade to next or previous version depending on hardware - with "Me" it was mostly 98se but I find 7 is usually a better option for vista boxes).Leave a comment:

Re: The 2014 Operating System Thread
Personally I consider the biggest innovation was the move from program manager to explorer - everything between win95 and win7 was just evolution...
Also, a lot of people disliked the new look that came with XP (I thought it looked childish and on machines I had to use it on switched to classic mode).
I still don't understand why we weren't given a choice with Windows 8 - how many other people hacked windows 95 to use progman.exe as the shell in place of explorer.exe? (was a simple hack of an ini...Leave a comment:
