So my question is : -How to now from the spec if the led will look nice or will look like the one I already have ? -Where to buy 25-50 nive rgb leds for a fair price ? Regards, tReg.

howto make 3d shutter glasses?

I cannot find any instructable on making something like shutter glasses. my idea is: the left-eye image gets a white 10x10px rectangle in the top-left corner of the computer screen, the right-eye image gets a black rectangle. the shutter glasses would have a photoresistor glued (or somehow placed) onto that 10x10px-area for timing. but i don't know how to use that (binary) signal to control the transparency of the 2 LCDs. i don't even know which LCDs to use or where to buy it.

Howto wire an AVR programmer to a microcontroller-socket? Answered

Hi, i'm bloody new into electronics and i want to make these "animatronic cat ears". I bought an avr-programmer with a usb-jack on the one hand and a 10pin-jack on the other hand, a chip and sort of a exchange-socket (dunno how it's called). Now i'd have to solder the socket (2x8 pins) onto a piece of breadboard and connect it to the 10pin-jack of the programmer  (otherwise i'd have to buy new programmer with socket for expensive 20 bucks). I can't really find the info howto wire things and i'm a lil bit afraid of frying things.

Raspberry Pi PC temp checker

Hello forum, I'm planning on buying a raspberry Pi this week. I know a couple programming languages, but only the basics. I've had this idea for quite a while: Connect multiple thermal sensors to the Pi, and then connect the Pi to my old Android cellphone (Nexus 2), and mount the phone to my PC case, so I get read outs for the PC components (CPU, VGA, PSU, HDD, and so on). Can someone help me, and explain how I can do this? I see it as a fun hobby to get into programming, and also reuse a cell phone, so I don't throw it away.

One year old dog will not accept my new three month old puppy?

I have a one year old female husky mix (Nova). I rescued her from the pound when she was six months old. Nova loves women and children but has been afraid of men since I have had her. Nova is usually dog aggressive.. but not always. I thought that she would do well with a puppy. Clearly, I was wrong! I picked up a three month old female husky mix (Luna) two days ago. I allowed Nova to sniff Luna's scent on a jacket. Nova seemed extremely curious and even wagged her tail. I was impressed. I held Nova by her harness while we brought Luna into our house. Nova became extremely excited! Once Nova was calm I allowed her to sniff Luna out. As soon as Luna moved her head, Nova snapped at her face? Nova will follow her around the house standing stiffly and walking tall. I am unsure if this is to show she is dominant? Probably. If Luna tries to go anywhere as in near the fire place(where Nova lays every now and then), near my children or myself, Nova steps in front of Luna being territorial. Nova has snapped at Luna multiple times and has made Luna yelp. A few times Nova attempted to play with Luna by pawing at her, but she accidently hurt Luna. All of this is still going on along with now Nova is growling at Luna. I am afraid to let them "sort it out". What can I do to help Nova accept Luna?

3d Scanning Howto? best recommended? DYI vs purchased

Hey gang! So, I am in need of some help.   The end goal is to make some  1x1x1 or 2x2x2 inch figurines of my kids. (  Think DnD wizard with my sons face") as the end goal. Right now, I am wondering if anyone has any success with the Scanning side of things.  Can you recommend a DIY 3d scanning solution? On Friday, I took my Nikon DSRL and put a 2"x2"x2" clay figuring on a rotating table and took some pictures, and uploaded it to 123d Catch.  I took about 30 pictures and uploaded them.  some where ignored because of lighting maybe. I have search for 3d scanning on instructables, and found quite a few, but it would be too costly to try them all, so I though I would ask in public chat if anyone has good success.   (I know I can spend 1500 on the maker scanner, but thats crazy expensive for a toy) So putting this out there for anyone to help me out

Building a capacitor charging unit

I was looking for a HowTo on building a capacitor charging unit. I saw a thread on a forum a while back that said you could create a large EM Pulse by sending a huge current down a coil of wire. I was looking about wiring up a bunch of these 220uF caps from Maplin;=12777&doy;=28m9#specThey are the last ones on the list.Would a few of these be sufficient to produce a large EM field, one that could fry sensitive electronic equipment. And how would i go about charging them all to the full capacity.Also while on this topic, would this be an efficient way of generating an EM pulse, or could you suggest any other ways of doing so.
