^ Soldering iron stand for the v-shaped piece was what I had in mind first as well (or perhaps a hot air wand "stand". But the other piece, I really couldn't think of anything. My first guess was some kind of special mobile phone and/or tablet test jig / holder. But a hot glue holder?? - no way. I just put my hot glue gun on the bench and hope that it doesn't leak (seems as some of my hot glue guns get older, the start to leak glue a lot more). That's one reason I don't keep them nozzle facing down anymore.

Default Re: The ghetto mod thread - summer house P3 PC

I did a few upgrades to the summer house Pentium 3 PC, posted here:
https://www.badcaps.net/forum/showpo...&postcount=603

Basically, one of the upgrades was that I changed the video card to a Sapphire Radeon 9600. Being a passively-cooled video card, I decided to put a fan to blow some air across its heatsink, as it would get pretty hot when running games. This is the ghetto-mod:


The fan is held by a piece of steel sheet bent into an “L” shape (so that the fan wouldn’t flap around, as the steel sheet I used is rather thin). The steel sheet piece is held with a screw to the case and the fan is held with another screw. I cut it to a length that puts the fan right over the heatsink. As for the fan, it came out of a gutless broken L&C PSU I got from a repair shop (this one, actually). It’s a Foxconn 80 mm fan rated for 0.14A or thereabout. I connected it directly to a floppy drive connector to run @ 7V (‘+’ lead connected to 12V rail and ‘-‘ lead connected to 5V rail), so that way it is both quiet and still pushes enough air to keep the card cool.

Other ghetto mods in that PC…
You’ve probably noticed one of the cut IDE cables with red electrical tape.
Also not visible in that picture but there: CPU fan is also connected to run @ 7V, because otherwise it is very loud. For this, I took out the black wire from the fan connector and shoved it in the back of a spare molex connector, hooked to the 5V rail. And because of doing this, the motherboard no longer shows the fan tacho/RPM… but that’s not an issue. The fan is still audible even @ 7V, so I will hear it if it stops. The 933 MHz Pentium 3 CPU still cools absolutely fine that way.

All my hot glue guns "leak" because they're cheap and all the trigger does is feed the glue, and depend on the viscosity of the glue from letting it drip.

In fact are there any hot glue guns that actually block off the nozzle? I end up putting them on their side if I *really* didn't want them to drip, else... I just let them drip.

^ I hate drippy glue guns - it's a waste of glue.

The one I have is from Michael's (arts and crafts store in the US). Probably the best and cheapest glue guns I've bought ($2 or $3 I think). It doesn't drip when new. But if you leave it overheat for too long, it will start getting drippy over time. Mine's fairly old (about 13 years) so it's gotten a bit drippy. Only way to stop it is to lay it on the side... and also not plug it in until ready to use. Once it starts "self-feeding", that's when I use it. When done, I unplug it.

The other same one I have, it's still very tight and does not drip at all.

I haven't seen any that fancy.

Mine would possibly drip if I used it sufficiently, but I don't do much with it.

I did have an awfully cheap ($1) one before, which fell apart. I pulled the trigger, and the glue stick pushed the heater and nozzle out the end of the gun. The plastic around the screws had softened... Then again, it was only rated for 220v and I get 237v at home.

yeah, mine drip. I'm so cheap I reuse the drops by remelting on the tip and reuse as much as possible, true ghetto style

^ Ha, me too!

Actually, doing that is not too bad. Now try doing the same with old pealed and yellowed hot glue. It will re-melt, but don't expect it to hold too long. I do that on my cheap multimeter leads when their hot glue starts to degrade and brake off. Each time this happens, the glue holds less and less (typically around 1/2-1 year, though, so that's not bad).

Default Re: The ghetto mod thread

I have so many computers and junk in my room that EMI/RFI runs rampant. Not to mention the fact that there's an A/C condenser unit with 2 VFDs next to my bathroom. I also like listening to the radio. Obviously, there's a problem: 99% of the stations on the dial are swamped.

Here's my fix. I have some shielded wire from an industrial thermocouple attached to the stereo receiver's 75 ohm input. The shield is connected to ground. This goes to a set of jumper clips which goes to some bell wire. The white wire is connected back to the stereo receiver's ground, but is also connected to a ground stake driven into the ground. The red wire (signal) is connected to a homemade all-direction antenna, which was held from falling by a pair of old wire strippers. All the wire is held in place with staples.

This takes me from getting a couple staticy stations to 19 or 20 stations in crystal-clear stereo.

Suck it, RFI.
And bite me, FCC.

^ Man, all of that long unshielded wire... just pray a lightning doesn't strike near your house, as that can easily fry your stereo (or at the very least, the receiver portion inside). Otherwise, everything else is proper
