Transforming Halloween

Ever since seeing the Transformers movie I just couldn't stop thinking about transformers. So I decided a Transformer costume was it this year. It started out as just a box and later became more elaborate and more of a car. IT IS FINALLY DONE. Took three months but it's done. Pictures of the final product is here. Today I took it to school for a contest. I probably transformed at least twenty times. At one point the tape wasn't working on the spoiler because the "haters" would tear it off. So we used a bolt instead. In the contest people were chanting my name and I won ... a cheapy blue necklace. But now whenever I was going around the block all I would hear is "Are you the Transformer kid? Transform for us". Of course I would. So if anyone has questions or wants me to post instructions let me know. The instructions will be hard because of the variety of height and weight.

Knex transformers poll

 I am considering posting my knex transformers 09 Bumblebee revision or Jazz. I am very busy and have only this month to post this poll. To enter just post a cleaver comment and I will judge if I will post my knex transformer by how many I get. If I don't get enough I wont post. The poll begins today and will end on September 20. I will make my decision on the 21st. There is one rule, I will not post both. So, happy posting.  So just as an update, seeing that no one cares for Jazz, I am deporting him from this poll. The poll is just about over and seeing that I have about eight posts, I am very close to making my decision.   If anyone wants to know if glitched is still posting, it is doubtful in my opinion. He told me personally that he is very busy and I believe it too.  Keep up the commenting and happy birthday jandeboer25!

Knex Transformer Contest

Ok so i had Another idea which needed its own posting I want peopel to show me there own transforming creating out of knex and whichever i think is the best and most clever will get instruction to any of my transformers of their choosing and only the winner will get the instructions and they are not to be posted these are for you only. The rules: -It can be an size as long as it is a complete transforming w/o taking it apart. -Being an actual transformer is preffered to make it easier to judge. -being creative is a must Ill probably let this go for about 1 month to make my decision so lets see what you got. Update: well obviously its been more than a month but only because not many were on board for the initial idea of this. So I will honor the deal for an awesome submission.

"What's that awful smell?"

Right at the end of our daily meeting this foul stench began to swirl around us. We couldn't quite figure out what or where it was coming from, but it was nasty. At first we checked the laser cutter since some people in the building like to occasionally burn Stuff That Shouldn't Be Burned and oh man does it reek. But that wasn't it. We check the fridge, but it was fine. We even discovered that it was just inside the building, but we had no luck figuring it out. Then Mike from Potenco walked down the hall and said, "Oh, hey, sorry about the smell. I blew up the transformer." He grinned and walked off to find all the fans in the building to air the place out. Just another day at the tower and another experiment gone awry. But if you don't blow anything up, then you're not going to make any real progress, right?

Transform a conventional ink-jet printer into a 8000$ laser etcher?

I believe everything is possible, with a little bit of help and that's what I need now. I can't build out those fancy CNC machine found here, since it's beyond my knowledge and skills. However, I thought about modifying a cheap ink-jet printer to make it into a DIY laser etcher this way: -Replace the ink part with a custom laser - instead of giving a current in order to flow ink, the laser will be powered. Laser requires different power level depending on the material, perhaps a potentiometer knob on the laser power supply could do it? -Remove any rolls and paper-only specification: instead, make THINGS able to go inside by simply destroying the printer, rising it up, and use the bottom paper rolls as the Y axis motorization. (The ink-jet head will be the X axis). Why would I do this? I have no idea how to programm small electronic chips, even less how to hook them up to computer or software. I, however, am able to print black and white images, and believe the black can simply be a signal to "laser on". I strongly believe this is possible. Since I can't, as stated above, mess with microcontrollers, I suggest adding potentiometers to the motors and laser and calibrate it myself, and adding physical marks (e.g: sharpie marks) to mark my settings. My question is: Do you think it is? What else could be required? Did I miss some obvious point that would render the previous idea totally worthless, and is this point solvable? Please comment :)

Help! My low voltage, outdoor lighting wont light up - transformer error codes?

I bought a Portfolio 300watt transformer for low voltage outdoor lighting and hooked up a 100' 12 gauge cable (outdoor rated lighting cable) to it. Then I hooked up 4 low voltage lights (12volt 20 watts each). I plugged the transformer in to a gfi outlet that I ran out from the house. And turned it on. The little display flashes "E" and then "1" . The instructions say that the E means that there is a fire hazard so check the circut. So I unhooked every light except one. Same error. I hooked on a different light and unhooked the first one. Same error. Instructions say the cable needs to be under 250'. And the load less than 300w. I am there, except it won't run. Do I have a bad transformer or is there something that I am missing? Oh, and this is to light my haunt in my front yard, so I am running out of time! Thanks for any advice! Matt

Undercabinet LED lights from 110v source

Hello, Ever since i moved into my current home I have wanted to put in under-cabinet lights in the kitchen. Its a small kitchen but the current fluorescent lights are just not giving me the light I'd like.  Powering the LEDs is my only concern. There are two under-cabinet areas each with one type of florescent light fixture with a normal 110v power line running into each light directly from a small hole in the wall (all hidden of course under the cabinets). There is no power outlet associated with these two lights. There is one outlet along the wall but I would not like to use this if possible as it powers the kitchen appliances, and it would show the power cord from the lights (Id love for these new LEDs to remain hidden.) I understand to use a 110v source I would need a LED transformer of some kind, I have seen these for sale, but I do not have an outlet that this transformer can plug into. Like this: Is there a way to connect a type of transformer to this direct 110v line? Would I splice the plug off the end of the transformer and just crimp it to the 110v source from the wall?  Like the end of this transformer: Im currently at work but if pictures help I can upload them later. Thanks!

Sturdy folding table? (life edited)

I recently found this thing called Life Edited. It's partly about making the most out of your space with multi purpose spaces and having most you furniture either being able to stack/fold away or being transformed. So for example by having your bed folding into the wall and dining table folding into the other wall, you could have a room that doubles as dining/bedroom. Anyway I started drawing up solutions for my home, it's all going well except for one problem. It is that my desk takes up a lot of space in the room. I have two requirements for my desk: 1. it has to be ergonomic 2. it has to be very sturdy, no what so ever wobble or play. I have a such desk, but I really can not figure out how to make it fold/stack/transformable without affecting the sturdiness. any ideas or suggestions would be much appreciated!

Okay everyone, I have been trying to remember what these toys were called for the last couple of years.  They were in the 80's or 90's and could change from a vehicle into a base/battle station. I know I had a few of them.  The two that I remember are a tank that changed into a large base and a three-wheeled vehicle that changed into a gun turret thing (if memory serves me correctly). There was normally a switch or button to press and you would hear a loud gear/spring noise when they changed.  I know it was not a Transformer or GI Joe toy. They had small scaled human figures that were tan in color and a little larger than the figures that came with Technozoids (if anyone remembers those).  The figures were in the same "seated position" (for lack of a better way to describe it) as the Technozoid ones. As I said in the title, there will be a 1 year pro membership to whoever figures this out first!

Microwave stopped heating and I fixed it.

Our microwave is about two years old and it stopped heating. The fan ran and the carousel went around, but food did not warm. I took it out of the upper cabinet mount and opened the case. I know about the big capacitor and discharged it with a screwdriver after disconnecting the power. For extra safety I clipped a jumper wire on both terminals. I watched numerous videos at YouTube on troubleshooting a microwave and on testing the various major components at home, but no component showed any signs of failure. Then it began to work again as suddenly as it had stopped working. About ten days later, it stopped heating again. After more testing, still no components showed signs of failure. But, I did squeeze the female spade crimp connectors a little with a pair of pliers before connecting them again so they fit more tightly when reconnected. The microwave has continued to work as it should. My wife remembers a time a few months ago when she ran it and ran it to get something to cook as she wanted it and the microwave stopped because it was overheated. I suspect a connection was weak and heated the metal in the connector enough that it became weak. Later it failed intermittently. We could have called warranty service, but we did not want to wait. Knowing what I know now, I doubt a serviceman would have patiently checked for weak connections, but would probably have simply replaced some parts. When those did not really solve the problem, the microwave would have been condemned and replaced. A replacement oven may not have matched our other appliances as well as our present microwave does. Test procedures for components in a microwave are different than they are for similar components used in (for example) a sound amplifier. This applies especially to the high voltsge diode. Do not connect a voltmeter to the high voltage side of the transformer. When running the microwave, be certain to have a dummy load in the cavity, like a cup of water. A very useful test that checks for power to the transormer primary is to disconnect the primary side transformer connectors and attach aligator clips from a voltmeter to the transformer leads. Then run the microwave for a few seconds and check for a full line voltage reading each time. A clamping ammeter to measure line current helps because the sound with the magnetron working is not too much differnt from the fan and carousel running without the magnetron working, but, it is easy to see the extra needle deflection when the magnetron is also drawing current.What seemed to be an expensive problem had an easy inexpensive solution.

If i put too much input signal into my little amp will it burn?

 I'm building a 5 speaker boom box out of a heineken beer keg. For the input interface and amplifying, i'm using an old pc speaker amplifier circuit, and i want to do the following changes to it: Put 3 input jacks, altogether (plugged into the same spot of the circuit): 1x   3.5 mm jack for mp3 player input. Kind of Aux input.                                                      2X  1/4" jack for two guitars or another combination of instruments. Put another output jack, 1/4", additional to the 3.5mm already there. Questions: If i plug too much things in will the amplifier burn or explode?                      Will it be able to drive 5 speakers (1x 1.5", 2x 2" and 2x 4" approx.) Other info: it runs with a little transformer of 220v/60hz to 9V DC. The speakers were rated to 110V/60hz. Does this means it acctualy runs on 4.5V DC?
