A little help with identifying Ceramic Capacitors?

A friend asked me to fix his tv's power supply, and i accepted the challenge. Upon closer inspection of the circuit board of the power supply, i saw that a resistor bridge, a rectifier, a diode, a capacitor and 2 power transistors were blown. I purchased the appropriate replacements, and as i was about to install them earlier today I saw that two ceramic capacitors are blown. One of them has '684J' printed on it, the other has "SCK 206 or 296" printed on it I need a little bit of advice on what replacement capacitors to buy, or if i should take them out of the circuit. I could leave them out, because they seem to hook up to a rectifier and then to a transistor, but i would rather buy the appropriate replacement capacitors. Thanks!

Computer Power Supple to Power 2 Computer Fans

I have a wine fridge with two fans (computer fans)  that cool a massive heat sink, but the temperature gauge is faulty so they constantly power on and power off. I was hoping to remove the existing controller and power the existing computer fans (that are already mounted) with an old Computer Power Supply to have them constantly on. Any ideas?

What would you do with five 5 v 75 amp power supplies?

I have these lying around and I know they are useful, but I'm just not sure how.

Solar power for a laptop

Hello everyone I have an idea to build a solar power suppl for a laptop using a 12"x12" solar cell. M question is this, if I solder the leads from a power inverter to the solar cell, it should be able to power or charge a laptop correct? Is there something else I would have to do?

FIMO clay, how to re-constitute it ?

I have a lot of FIMO,and I just opened a pack of it. It started to crumble when I tried to shape it on the ends. I tried some water, no help, I tried to warm it a little, no good. Anyone know how to make it supple and workable again. Maybe some type of oil ? Not sure what is in it. No ingredients on the package. Thanks.

Can I wire an LED directly to an AC DC power supply?

Hi everyone,  This is my first time posting on Instructables.com so please forgive my noobness! Here is my issue: I have an idea of a really nice lamp to make for my girlfriend using a single 8W High-powered LED (http://shop.rabtron.co.za/catalog/high-power-white-p-7492.html) powered with a 12V 500mA AC DC Adapter (http://shop.rabtron.co.za/catalog/adaptor-500ma-fixed-p-6289.html) First off, is this possible? If not, why not and what is the correct way to go about it? Secondly, will this LED be bright enough for a desk lamp?  Thanks all! Happy instructing!

How to Upholster a Box

In my quest for weeding out my less than professional looking projects, I am in need to learning a new skill.Does anyone have recommendations for a resource on how to upholster a box? Key points including the box material is a thin plywood which probably won't hold up to staples (thicker woods are heavier and I have a weight restriction for this project: lighter = better). My material will be a marine vinyl (for weather protection) which does have some stretch to it - I'm also going to put a thin foam backer for that extra supple feeling.Recommendations for obscure compound curves would be nice too.I'm armed with a sewing machine, limited sewing skills, bandages and some scrap material. <-- that on top of the typical measuring instruments.

[Help question] Funai W4D-D4180DB of "ATX Power Supply" convert

Now I can be understand about a DVD Players (+12V) anyway -> youtube.com/watch?v=dtRIzy2j2xs (Not my Clip,Just I watched this.) ----- But I had a problem about a Addition (or maybe not) but I will be had of a Motherboard detail question about a Volts: +44V +16V When how are be possible to start without a "+44V" problems of a ATX's pins...? ----- When I do be had a Good think that will be (maybe,but I doesn't be had a sure) possible of a 34-to-20pin convert because that's can be work. (Stock power supply of Combo Recorder are be a 35W of 230V) - but maybe Connects are be questionable anyway... ---- In Photos: 1. "PSU" write signet detail of Motherboard for Help respond' 2. Motherboard (If you want of a Volts Detail, then I will be can a upload addition photos)

Giant Robot Architecture Talk by Greg Lynn in Berkeley

Here is an interesting talk from the Art, Technology, and Culture Colloquium of the Berkeley Center for New Media...Giant Robot ArchitectureGreg Lynn, UCLA & Angewandte, ViennaMonday, Feb 4, 7:30-9:00pm- Note Special Location: Berkeley Art Museum Theater- Enter on Dwight Ave: http://bampfa.berkeley.edu/visit/visitor- Lecture is free and open to the publicAbstractRobots. In my office, my staff keeps asking for more new machines, and every time I get a new machine, I fire two or three people. By extrapolation, in the next few years I will be sitting in an office by myself with a bunch of robots. We have is a very large CNC (computer numerically controlled) cutting machine, a laser cutter, a 3d printer, and soon we will have a robotic articulated arm. All of these things let us do studies of models, which are very important to architects, but what they also let us do is learn machine language. We spend more and more time talking to machines; speaking their language. It is very easy for us to go to any country that has an automobile industry or an aircraft industry and give their machines instructions and do things with these large machines at an architectural scale that is very perfunctory and affordable. The spread of machine language and programming is more significant than the Anglicization of the world. Learning to talk to robots is very important to my field of design.Speaker BioGreg Lynn is a leading pioneer at the intersection of computing, design, and architecture. His architectural designs have been exhibited in both architecture and art museums including the 2000 Venice Biennale of Architecture where he represented the United States in the American Pavilion. His work is in the permanent collections of CCA, SFMoMA, and MoMA and has been exhibited at the Pompidou, Beyeler, Cooper Hewitt, MAK, MoCA, NAI,Carnegie, ICA and Secession museums among others. In addition to his architectural work, his Alessi "Supple"Mocha Cups and his Vitra "Ravioli" Chair are in production and have been inducted into the Museum of Modern Art's Permanent Collection. He received the American Academy of Arts & Letters Architecture Award in 2003. In 2002, he left his position as the Professor of Spatial Conception and Exploration at the ETHZ (Swiss Federal Institute of Technology Zurich) and became an Ordentlicher University Professor at the University of Applied Arts in Vienna.He is studio professor of Architecture at UCLA and the Davenport Visiting Professor at Yale University. Greg Lynn holds degrees in architecture and philosophy and received an Honorary Doctorate degree from the Academy of Fine Arts &Design; in Bratislava. In 2001, Time Magazine named him one of 100 of the most innovative people in the world for the 21st century. In 2005, Forbes Magazine named him one of the ten most influential living architects.http://www.glform.comMore info on the colloquium here.
