Testing a Cheap Multimeter

It's been years since I had an expensive meter. These days, I have meters in the $5 to $20 range. Usually they're accurate enough for my purposes, but what if I want to be really certain? Is there a way without a pricey meter to test em?  Perhaps calibrate the meter by checking v  coming out of a v regultor. Would that be accurate? Perhaps the 7805 regulator which is supposed to output 5v.  y?n? M?

Rolson hand tool sale?

Not sure if this is a local thing or whether it's also going on elsewhere, but Tesco in Cambridge is having a sale on Rolson tools: I got a pair of safety goggles, four pack of clamps and a junior hacksaw for a pound each, and there's more (mostly hand tools) to be had.  I know all the adages about buying cheap tools, but at that price I'd happily use them as raw materials for a one-off make.   UKinese members, check out the hardware aisle in your local big Tesco, thar be (potentially) bargains.  Now I'll have to work out something to do with them all...

Looking for any and all ideas/advice for building my own eco home on the cheap

Hi, I am looking for any and all info related to building my own low cost eco house. Off grid if possible. I moved to France last year and purchased a 1 Ha piece of land. I had a good job and the world was our oyster. Then, on Friday the 13th, 2013 I lost my job. I also lost everything we owned in the world when it burned to the ground along with the storage facility it was in - and almost no insurance. This all happened within 90 minutes. I am not looking for sympathy or charity, just good advice. My wife and I are not going to give up on the dream, we just need to chase it on a much reduced budget!   Currently I am clearing the 2 acres (1 Hectare) which is overgrown with about 3000 pine trees, and, thorn bushes that are 3-4 yards tall in some places. I hope there are some fellow dreamers here willing to share their ideas, designs, experience and knowledge. Thanks so much.

Looking for inexpensive source of RGB (Star) Luxeon LEDs.

I have an upcoming project that requires lighting a 10' x 10' matrix of 12" square LED driven lightboxes. The only requirement is the capability to display a broad range of color - hence the need for RGB LEDs. I'd like to go with more of a high-output Luxeon star mounted LED (1 or 3 watt) versus using several standard RGB dome LEDs. I figure that I can get away with using 1 Luxeon instead of 6-8 standard LEDs. My question is... does anyone have a reliable source for purchasing these LEDs inexpensively? I've seen several projects where people are getting 1W white units for around $3, but the Tri-color are selling online for around $14-$16 each. Any ideas?

How to Make a Cheap Data Acquisition System

Hello. I am new to this forum. I am a Physics  (Optics) student and i do not have access to a good data acquisition system. I tried data acquisition with Arduino Due (in under 40$) but it can only sample frequencies up to 1KHz. Is there any other cheap way to make a better DAQ system with higher speeds? By cheap i mean under 50$. P.S. My electronics knowledge is not very good so please discuss in detail.

Budget Bowl Lathe

I salvaged an AC motor from an old water pump I found on the side of the road and want to use it to make a simple lathe for turning green wood bowls and cups.  I was thinking about using a floor flange as the face plate, a nipple for the shaft and pillow bearing blocks to support it.  This assembly would be driven by a v belt and controlled by the speed controller from a jig saw.  I attached pictures of the components and a simple cad drawing of the assembly. Do you think this would be functional? Any recommendations?

Using a USB Bluetooth bundle into a home brewed device

Hey everyone, I am a student in software engineering and I am leading a project with other folks in software and electric engineering as some artists which consist of developing a computer game that use a home brewed device. That device is essentially a wii-mote ripoff: we will use some gyroscopes and accelerometer to get user input. However, some of the parts we are looking for are very expensive, we need to do 3 of theses devices and we don't have a big budget :) Since the most expensive part is the bluetooth transmitter (our device needs to be wireless), I was looking for a workaround. First, why bluetooth? Well we thought using some FM or RF stuff, however that implies some rare stuff that is not embedded in our student computers and even more expensive... So that's why we thought using bluetooth... And my question is... Is that possible and not so complicated to use those cheap USB bluetooth bundle such as these ones: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords;=bluetooth+adapter ? When I say not so complicated, I mean that we won't have a big controller... we will have just what we need to get the data from analogical sensors turn it into digital data and send it over USB. Looking over the web I found that some RS232 to bluetooth bundles exists, however they are very expensive... It might be an utopia, electrical stuff is really not my field of study. Thanks for your help!

So...what would YOU do with a broken Win98 computer?

Well...I'm sure you have seen this forum post about me trying to find out what was wrong with my computer. It is WAS a Windows 98 computer.We took it to the guy to fix it, and he said that the fan cooling the CPU stopped (!). Then it fried itself (*sigh*) and somehow messed up the memory as well. THEN he said he replaced those components, and it STILL didn't work! So he basically (but not really) said, "Well, I guess you're screwed...want to buy one of our ridiculously high priced computers to replace it?"*sigh*Well, I was gonna tear it down...I know I can get hard drive magnets and stuff from it, a (?) power supply, various lasers from the CD drive, and other stuff.I KNOW you guys have some good ideas. What would YOU make if you had the entire computer to tear apart?

Building a Computer

So, in continuing my series of stupid newbie computer questions, I present: Building Your Own Computer!-The Computer-As you've heard, I first had a computer that messed up, then I took it to the computer dudes, and they said it was completely FUBAR, then I asked how I should salvage it. Now, after laying my eyes on the beautiful Linux-running $72 Computer, I said to myself that I should make one...-What I Have-I stripped my computer tonight, and I came up with a CD drive (doesn't burn, just reads), Floppy drive, hard drive, power supply (how the heck do I understand all those wires?), nice looking heatsink with matching fan, and various other parts from the Windows 98 computer. -The Problems--I checked the links provided at the link above, and the prices had either raised, the item is out of stock, or the item had vanished completely...-I would like to buy a minimum of parts because I am in debt with my parents, and being 13, I don't have a job to pay them off.-I would like to run Linux, as it is one of the coolest things I've found recently. -I do know that the link above is thumb-drive booted, and I would like to avoid that, but no biggie if I can't.-I also don't know that much about computers, so I want to keep the computer sweet and simple. -The components that I salvaged might not work with the new components (I.E. Motherboard)-Maybe more.-Pluses--It will be cheap.-Case mods should be easy.-Mistakes dont cost much.-Linux is free.-Linux looks very nice.-It shouldn't need much RAM to run (Am I correct here?), so I can run more complex programs without it costing me.-I have extra parts from the old Win98 computer that died.-Probably more, but this is all I got right now...First postSecond postI am saying this right now- I suck at understanding computers, and if possible, comment to me like you would your 93 year old grandpa.

Searching for a cheap Quadcopter(Used, kit, or anything)

Hello. Im a young filmmaker and DIY guy with no money because of my college. I Have a project in mind that involves my GoPro and a quadcopter. Only problem is that i don't have a quadcopter, neither money to buy one. I searched on ebay for a cheap one, but I find only small ones and at a pretty expensive price for what you get($40). Does someone have any quadcopter or a KIT quadcopter, or a wrecked quadcopter thats easy to repair, or maybe a good soul that would give one away for cheap to a dreamer student?  I would pay the shipping too, but I would need it to be shipped to croatia... Anyone like that? Please help me..
