I recently added something new to my collection, a 50 inch flat screen DLP TV. The best part of this, is the fact that I got it for nearly free! I am not one to normally take things from the side of the road during garbage pick-up times, but a potentially working, free, 50 inch, flat screen, HD TV is worth it!
The TV barely fit in my trunk, I had to put down the two back seats, and somehow manage to lift it in there. It is around 50-70 pounds, not too heavy, but considering that it is this monstrous mammoth of a machine, it was a bit harder than I was thinking.
I was on my way to my girlfriends at the time, and once I got there, we took it in and tried to turn it on... nothing... just blinking lights. Darn, oh well though right, it was free after all. I proceeded to look around the TV, and found an easy hole in the back to open, I then found a bulb inside of it, it is a projection TV after all. I couldn't see if the bulb was damaged or anything, but I figured it was just too old.
I thought about it for awhile, and had heard that the usual cause of this is the bulb being busted. I found the manual on-line, and in the section with the error light codes, it said that if all three lights flash once it turns off, then that means that the bulb needs to be looked at. I then, after awhile of searching, found a bulb for it on Amazon that was going for $39.88. I was reasonably sure that this would solve the issue, so I bought it, and waited.
It came in about 4 days earlier than expected, so in a very excited state, I replaced the old bulb with the new one, and I then put it in the TV. I was very happy to find out that it worked! I now have a working 50 inch TV! the next step, is to clean the mirror on the inside, its quite dirty.
Earlier this year, in what my colleagues have called "the sketchiest eBay deal ever", I bought a 30+ year old Nikon microscope from a dude in Singapore. I paid $200, including international shipping. Back in the day, these were $15000 microscopes. Depending on the exact accessories included, they usually go from $600-$6000 on the US eBay. I was honestly expecting to sink about $300 in parts into the scope. The focus gears are all made of extra-brittle plastic. I've done that repair eight or nine times, so I knew what I was getting into. I really lucked out, though. The only "problem" it has is being wired for European/Asian mains.
Hardly surprising, and not too much of a concern. The lamp housing is prone to breaking, and the most common fix is to just rewire it for LEDs. I wanted to see what I could do with parts just laying around the house (and I was too drunk to be able to drive to the shop). So let's see what's inside:
A 30-something year old wire-wound transformer that's kicking out 9V DC. Well. That definitely explains the heat these suckers generate. *snip snip snip snip snip* And yeah, I don't think I need that voltage selector switch anymore.
I'm a total sucker for switching regulators. I think they're the greatest invention ever (well, maybe not THE greatest, but pretty awesome). I've also got one that outputs 9V DC laying on the floor in the living room from when my modem bit the dust. A bit more breaking and snipping, and I've got my voltage converter.
I actually liked how the original transformer had been mounted in the scope, so I re-used that method. Not to mention, I didn't have anything else laying around.
One ubiquitous black power cord later, I'm even able to reuse the old strain relief.
BAM. I've got a professional quality microscope. Easily upgradeable and accessorizable.
I broke my phone when I was on vacation last month like a big dummy. I guess I sat on it but don't remember doing so, and the glass digitizer wasn't even cracked, just the screen below it which I find strange to be honest. Anyway, I ordered a new replacement with the digitizer already adhered to the LCD screen itself so I wouldn't have to bother with LOCA (liquid optical clear adhesive, which cures clear via UV rays) and it was a pretty easy replacement.
I got this Game Gear from Mulder a few weeks ago and she was kind enough to send a bunch of replacement capacitors along with it. I figured it was time to actually get my hands dirty and fix it up.
The GG itself is in great shape, but when I got it the screen image was pretty terrible. You could only see the image if you tilt it away from yourself about 70 degrees. Yesterday when I went to work on this I tested again and this time it was worse. After powering it on, it shut itself off after 1 second. Definitely time to replace the caps.
Started off on the left side of the board and only did 3 caps initially. I know I was pressing my luck, but I reassembled the GG to see if there was any change.
Already it was staying on and the screen was looking like a brand new GG (actually, I can't say for certain because I've never seen a brand new GG). Replaced the rest of the caps on the main board since I'm sure it would need to be done eventually. I didn't touch the caps on the amp board because volume is working perfectly, but I'll revisit if/when it becomes an issue.
Also started following Mulder's LED mod, but I have neither a 33 Ohm resistor nor any large white LEDs. I tested the mod with slightly more resistance and a yellow LED and it ended up being orange. I still have all the parts I removed for this mod so I could put it back together, but I think I'll wait until I get the right parts and do it right.

Thanks Mulder! I don't have a spare DS screen lying around, but I do have the backlights from a couple of dead ebay screens. I'll see if I can get one of those to work.
Anyway, I wanted to share another afternoon project I did. Completed this about 2 weeks ago, but didn't around to getting a pic of it finished until last night. I was inspired by a small wheelbarrow planter that ModPurist made and posted on his website and thought that his idea would make a perfect gift for my wife on our anniversary.
Started with the wheel first to get a feel for the size, then built the box around that. I used a jigsaw for all the cutting because the bandsaw needs a new blade. Jigsaws aren't great for cutting circles, but this is meant to be stationary, so I wasn't concerned about perfection.
Going off of one of ModPurist's pictures, I freehanded the box.
With the box assembled, I built the frame around it. Drilled holes in the forward arms for the axel. As for the axel, I salvaged a wooden dowel from a 5th grade art project.
Finished! I added a little detail by cutting a shape into the handles then sanding their edges smooth. The rest I left as-is to keep it nice and rustic. Also sprayed the whole thing with clearcoat to help prevent wood rot, since this will be left out in the elements in the spring/summer.

ok, so. dt has been in the process of getting the capture card to work properly on her pc so she can stream hdmi and component games. one of the issues was that she had no way to hear the audio, as right now, the screen she is using is a pc monitor that takes hdmi. it has no built in speakers.
enter me and my simple yet brilliant idea. all of these systems have a plain a/v out OR a digital audio out line. we have the a/v cords for them all and a digital to analog audio converter (for those that ONLY have digital audio out - xbox one for example).
it is just a very simple rca L & R jack straight to standard headphone jack. this allows dt to hear the systems and games while playing. i made it this simple, because her headset has its own volume control.
i do plan to make a full mixamp at a later date for her. but this makes it possible for her to stream those systems now.
I have a "Quick" mod that I did to free up space on my desk at school. It was quick, but that is only because it went together well, and isn't 100% finished. What I did was turn my laptop into an all in one unit. It was sitting on my desk being used with an external keyboard and mouse for the longest time, and I have a tiny netbook to take to class anyway, so I decided to turn it into an all in one unit. I basically took the screen, and laid it flat on the keyboard section, it was more detailed than that, but like I said, it isn't 100% done, I want to co casework back home to make it permanent, and give it a stand/feet. so far its functional though, and I am pleased with it.
Here are some pictures of it. I forgot to take pictures while building it, but when I do the case work, I will more properly document it.
