Hello LPF - it's been a while. I've been away working on other projects: http://reprap.org/wiki/RepRap - Prusa Mendel Things involving LiPo batteries - Quadrotor Blade Test - Clamped - YouTube Things involving even bigger motors: imgur: the simple image sharer Things involving lots of code...

HI all, I was just wondering what the "symptoms" of hitting the FlexDrive V5's thermal limiter are. I built a 445nm earlier, set at 1.3A in a custom host. (Build thread will probably appear at some point...) When the laser's been running for a minute or so, the output will blink at about 2hz...

Hi guys, I realise this may not be the best place to ask but I'm guessing a few of you will have contacts and places in the electronics industry, or have the knowledge to be able to point me in the right direction. I'm looking for a replacement camera LCD, model "AM311AKAA" from Sony, or a pin...

FavUpD_IjVY Erm, moo? What do you think? Must be the oddest thing I've seen in a month...

Just thought I'd publish this in here as well to make sure that as many people see it as possible. The basic idea is that we can, as a community, rent a PC game server. http://laserpointerforums.com/f58/lpf-game-server-source-games-52958.html It's easier if we keep the discussion to one thread...

Hi all, I know that there are a fair few PC gamers on here, and DJNY and I were discussing if it would be viable to set up a LPF gaming server. The poll is self-explanatory. Ideally we would rent a small server for Source-based games (maybe one evening of L4D, one for CS:S, another for HL...

My supplier recently emailed saying that they have a limited stock of BDR-203BK 8x sleds - with the recent 445nm craze I would have thought interest would have gone down somewhat, but is there still enough interest in these? I could match Glenn's GB price of under $100 shipped with about 5...

I'm ordering some bits and pieces from China and I was wondering if anyone else wanted to jump in with me. Pricing would be: about $7 for PHR or LPC about $18 for SF-AW210 I'll ask about higher diodes, but GGWs will be in the range of comfortably under $45 + your share of shipping to me from...

I have a set of laptop power supplies, both cheaply designed, both Chinese, and both failed or likely to fail (majorly overheating to the point of charred SMT remains in the one I opened up). I'm a cheapskate however, and I don't want to buy a pair of legit Dell chargers. I need a 19.5V...

Post 1000! I remember the day I first signed up,thinking that even 500 was an insane number of posts, but a year and a half on, and here I am, still typing away... It's been amazing to be a member of such a vibrant and wide-reaching community so far, and I certainly have no intention of...

I'm not sure what people think of this idea, but here goes: I know that on the forum we have a huge range of people, with access to different useful machinery and tools, through work, school or home, and I was wondering if people would find it useful to have a searchable list of people who are...

I have a collection of unprotected li-ion cells from a laptop battery, with voltages ranging from 2.8v to 1.9v. However, I've heard that these batteries can go open-circuit with copper build-up on the electrodes below a certain voltage, and are at risk of causing fire, but is there any limit...

I'm looking for a pair of LCD shutters, capable of running around 60hz. Anything 1in^2 or better is fine. Anyone got something similar to what I need?

Hi everyone, I've been working on my DT coursework, and I was wondering if anyone could share their experiences with anodisation of Aluminium. My design is a torch, following a simiilar design to the Kryton barrel (but less pretty :whistle:). The reflector and lens were stuck in using...

Hi all, I have a £15 iTunes card for my birthday, but I don't use the iTunes store much, so I'm looking to sell this. Code will be sent to any reputable members before I ask for payment, however if you're new or unknown I'd ask that you pay before I send the code. If you're going to buy...

I'm posting this here so it gets a bit more attention than it would in off-topic. I'd hope this isn't a problem, but it does relate closely to violet, since anyone who took apart a PS3 for the sled might still have one. The basic story is that my PS3 drive has died, and I'm pretty sure it is due...

Hey everyone: My two-year-and-a-half-ish old PS3's drive just died. I'm pretty sure it's out of warranty, so I think it's going to be cheapest to replace the drive myself. The drive doesn't sound like it's spinning up with any type of disc, so I believe it's to do with the part that spins the...

Hi all, I was wondering if anyone here has a low-power, pin-compatible version of the 555 timer spare. Ideally it should operate down to 1.5v or even as low as 1v if possible. If anyone has these to hand, it would save me the time and per-order costs of buying from one of the standard suppliers...

In 2 words: Pump failure. I've been running a water-cooling setup for quite some time now, about a year or so. Recently however, my pump had been tripping the "cpu fan speed" warning on my motherboard, but if I checked in the hardware monitor, it all appeared to be fine and the CPU temperature...

Hi all, I'm looking to design a current source (probably) based around an operational amplifier and transistor(s), which can source 0-500mA at 0-12v. This output current should be "set" by an input voltage of between 0 and 5v and remain constant. I presumed that you would have the load connected...
