In the case of humans that might make sense if hairiness was universal. It isn't. Some adults have little or nothing in the way of pubic hair or body hair. My own preference is hair on the head and eyebrows, only. The second I see hair anywhere else, it's a huge turnoff. I've actually known...

Thanks guys for the birthday wishes! And thanks CityK for the birthday gift! The #7 train in the beginning, and the shot of Queensboro Plaza 50 seconds in, is definitely on my list of NYC experiences-I've ridden that line literally hundreds of times, if not more. Really, anything subway is...

Ouch. :-o I'm going to hazard a guess that you either had an accident doing stuff around the house, or riding your bike. I'll let you know either way as soon as I make an attempt at it. A nice custom-machined enclosure would be nice. Heck, if we end up going that route, might as well...

I was pretty sick for much of the last few weeks, so things haven't progressed as rapidly as I thought they would. Don't forget also I'm basically designing this from scratch. If I was just copying an already built and proven design, it might have been done already. Just to update you, I've...

I was (maybe still am) seriously considering either Llano or the next generation APU for my next system. The reason is I anticipate eventually needing more graphics capability than either most onboard, or Intel's integrated graphics, provide but I don't want to buy a discrete graphics card. I...

I'm planning on 16 GB for my next upgrade. Even that I consider gross overkill but RAM now is stupidly cheap. I can't imagine what anyone would do with 192 GB.

They most definitely did. One of my grandfathers had an AMD VTCPU-01 1-bit vacuum tube processor running at 3 KHz with 12 bits of relay-based RAM. This was considered state of the art for the time. :rofl:

The goal of this project seems to be to recover the heat from machines which will be running regardless. Obviously if heating is your only goal it's easiest to just use a conventional heating set up. Incidentally, the one PC I have on in my bedroom 24/7 seems to make that room about 5°F warmer...

These are about as simple as you can get. I'm actually using something similar on the water block of my thermoelectric temperature chamber as a failsafe in case water flow is cut off. Mine came with some surplus TEC assemblies I bought.

Norelco 7345XL for me. I shave every day because I find stubble annoying. When I used to use a blade my face was always irritated, especially my neck. When I was in college I started using electrics. Big difference. Maybe they don't shave quite as close as a blade, but the advantages make...

This isn't a bad idea and I'm wondering if it could be taken a few steps further. I'm thinking along the lines of a hot water heating system for the entire house where the water is preheated first by low-level waste heat from various appliances ( computers, refrigerators, LED lighting ) before...

From my reading, one of the strengths of Llano is the integrated graphics are good enough to tolerably play many games, 2-3 times better than iCore, and better than just about all integrated motherboard graphics. Downsides are the regular computing performance and to some extent the price...

Unique data for me is what's on my hard drive. I have a combination of pictures I've taken, documents (Excel, MSWord), PC board CAD files, downloaded files of all sorts (images, news articles, data sheets, trainsim stuff, etc.), and my OS/apps. It still fits on my 200 GB boot drive, barely...

I'm putting the battery box and light engine together for my light because I don't want to run extra wires. Do you prefer that option for yourself also, or would you prefer the battery box to be separate (in which case you could put it in one of your water bottle cages)? The battery box needs...

That is a nice idea. My handlebars always get crowded with all the junk I mount on them. The stem seems a natural place to put stuff. I've yet to see anything exactly like you suggest. Seriously, I think the idea might be patentable. It's certainly marketable. The closest thing I've seen...

Yeah, they're all in series so if one goes open the string won't light. That's not really a concern though because LEDs almost never fail open circuit, and these aren't being overdriven. XP-Gs are speced for 1.5 amps. I'm only driving them at 1 amp tops. Most of the time it will be way less...

I would just put enough LEDs in series to come fairly close to the minimum operating voltage of the battery back (in this case about 10 volts so I would use 4 red LEDs in series), and then have a linear current regulator to absorb the remainder of the voltage difference. Another option is to...

Not hard at all. I've actually been running a similar setup on the Raleigh where I have a plug/wire to draw power from the headlight batteries for the taillight. It saves me the bother of messing with batteries for the taillight.

Yeah, that's kind of like the difference between my Raleigh and the Airborne. Unfortunately, I've yet to take the Airborne on a decent ride because it lacks a headlight. I ordered the batteries today, and this made my life worlds easier. I don't have to spend time designing a protection...

I've been designing and repairing electronics for over 25 years. To me my PC was just another broken piece of electronic equipment which could potentially be repaired. I hate discarding things which still have some useful life in them. That made attempting repair second nature. Now if this...

That's exactly the reason. In the scheme of things, spending an extra $50 on my next upgrade won't break the bank. I'm also interested in future-proofing any upgrade as much as possible since I tend to use systems for a long time in between upgrades. 16GB may seem outlandish now, but I might...

I'm strictly cash in brick-and-mortar stores except for large purchases (and I put those on credit card). The big problem for me with debit cards is keeping track of how much you have left in the account. My debit card draws on my checking account. Generally, I only put enough in there to...

For what it's worth, the time value of my money at this point is under 2%. Assuming I went with 16GB and spent $100 now, if it's selling for over $102 in 6 months I'm ahead. And there's a very good chance I might be upgrading in less than 6 months anyway. The graph looks like it bottomed out...

I've had the PC running now for 24 hours straight. I swapped in the supply from my mom's PC because the 5V rail was marginally better (21A instead of 20A) and my MB converts the CPU power from the 5V rail. Even though it's fixed, I'm probably going to upgrade sometime in the next 6 months...

I placed the order with Cutter. It usually takes 2 weeks give or take a few days. It'll probably take close to that long to finish up everything else anyhow. This place also had XP-Es, but mounted on a 20mm board. I would have had to dismount them from the 20mm board, and remount them on the...

Regarding not choosing the tint bins, it shouldn't be that big a deal. Cree (actually all the LED manufacturers) are getting pretty good in that you don't get horribly green or purplish tints any more. As for flux bins, Mouser appears to be selling by flux. The downside is they only have the...

Yeah, it would be something like that. I'm working out whether I can safely charge several of those cells in series at low current (i.e. overnight charge) without adding circuitry for cell balancing. I need to order emitters/optics from Cutter, which is probably 2 weeks to get to me. If...

Getting to some specifics, the setup I have uses 6 XP-Gs with 10mm optics. In retrospect it would have made more sense to use XP-Es, even though the raw lumen numbers are less, because the smaller die would be focused into a tighter beam by the optics. Right now I have about 7300 candela and...

Here's some pictures of the headlight I'm building. I still need to make the battery box and mounting bracket. Regulator board (ZXLD1370-can be configured as boost, buck-boost, or buck):

I think the 21 speeds probably includes super low gears which would make sense for the type of rider this bike is designed for. Obviously they're not going to climb 4% or 5% grades in a 42-26 gear at 12-14 mph like I do. ;) Since you wife hasn't ridden in 25 years, this is probably a good...

Is there any reason for getting a bike with a step-through frame? Those used to be used a lot back when women wore long, bulky dresses which would have made mounting a bike with traditional tubing difficult. The majority of women nowadays ride the same types of bikes men do. As for...

Actually, I think the MB is closer to 8 years old. I considered the work worthwhile because this was considered a high-end MB back in the day, at least judging from the reviews on the Newegg product page. Now whenever I upgrade the system can do limited duty as a second/backup machine.

I did it more to see if I could than anything else. I figure if I saved $300 in the short term it was probably worth the 5 or 6 hours spent on actual repair time. As a bonus, I also did some advance research for my next upgrade. ;) Here's a picture with the caps I replaced maked in red. One...

I think I got it fixed. It ran for 48 hours with the side cover off before I shut it down today to replace the 3300 uF caps. Not enough room to replace all the caps because the ones I had were larger diameter. I put in 4 out of 8. System booted into XP with the cover on just fine. So far it...

I tacked the caps onto a parts order for another project 25 pcs 1000 uF caps at 0.21 each = $5.25 15 pcs 3300 uF caps at 0.68 each = $10.20 sales tax = $1.37 TOTAL = $16.82 (actually less because I'll have nine 1000 uF caps and seven 3300 uF caps left over for other projects) I'm not counting...

I put in the 1000 uF caps. Still the same thing-stable with the cover off, shuts down randomly with it on. Last thing to do is change out the 3300 uF caps around the CPU. The caps I bought were too big. I need to order 10mm Sanyos on eBay. Even though the caps on my MB weren't the...

I haven't yet replaced the 13 1000 uF caps but the system has been running all night without shutting down. I noticed a funny thing-the system seems stable so long as I have the case open. And it doesn't appear to be a thermal issue. The system was unstable with the case closed even from a...

Everything in the first post sounds reasonable. Give me some time to get back on specifics. I'm posting now from my A78NX which is marginally stable. I'll post in more detail when I'm on a machine which isn't in danger of randomly shutting down.

I replaced the 2 820 uF caps which were bulging. The eight 3300 uf caps near the microprocessor seem OK. They're Rubicons, not the problematic Nichicons. The system is better, but still not 100% stable. In fact, I'm writing this post from it right now. I suspect I may need to replace the 13...

More updates. I removed the extra caps on the graphics card but the system is doing the same thing. Now it won't even boot to XP. Since the graphics card caps were indeed bad, and I replaced them, we can pretty much assume now the graphics card wasn't the problem, although it may have made...

They used neutral white to mean like halogen track lighting, so it's really warm white. And there's a huge market for neutral white (3500K to 5000K). 3500K and 5000K CFLs at the local Home Depot are always nearly sold out. Despite the fixation of trying to imitate incandescent with both CFLs and...

The extra caps made it worse. I'm not wasting any more time playing around with this video card. Since it seems the card may be causing some or all of my problems, I'll get a new one. Truth is even when this card was brand new it would sometimes crash when playing 3D games for a few hours. Any...

Well, looks like you may be right. I just took out the graphics card and noticed 3 bulging caps (6.3V, 1000uF). I didn't have this value handy, so I replaced them each with a pair of 16V, 470 uF solid caps. System posted fine, did a memory test, and attemped to boot into XP. No luck. I booted...

For what it's worth, a few weeks before I noticed that sometimes I would get jumbled screen displays when doing things like photo editing. When I jumped to other apps and back to the photo editing software, all was well. I do have another graphics cards in my mom's machine to test, but I'm...

Well, the machine wouldn't even post today. I guess it's definitive that it's not an HDD issue. On the potential replacement machine, I do in fact want something with some graphics grunt because there are several new train simulators out which I'm planning to purchase eventually. MSTS, like my...

I removed and reseated the graphics card just in case there might have been a contact issue. No, I didn't disconnect the HDDs in Ubuntu, but there shouldn't have been HDD access given that I booted from CD. Like I said, I'm nearly certain this is a bad cap issue. I'll know for sure when the caps...

I checked all the obvious stuff like the CMOS backup battery. I'm nearly 100% certain this is a bad capacitor problem. I've read that failing hard disks can give similar symptoms (and my boot disk is a vintage 2005 200GB Maxtor) but I don't think that's the case here. I managed to boot to Ubuntu...

My A7N8X-E may finally have given up the ghost. It was periodicly experiencing total freezes, and they were getting more and more frequent. Last night I figured I would open the computer up, dust it off inside, reseat the RAM, and replace the thermal compound on the processor heat sink. That...

Not really. There is a payback period for electrification for sure, but in the long haul it's cheaper to run an electrified RR than a diesel one, except in cases of low traffic volume. This is why most of the world has electrified their main lines other than the US. Here is a special case...

Those prices are why I'm going the DIY route (and just for the joy of making it myself). Also, I have total flexibility programming the number of light levels via a microcontroller. Runtime on full should be around 90 minutes but I plan to have multiple levels spaced 20% apart, down to maybe...
