First up , I wanted to mention this luminous flowerpot clock with LED pistils and modeling-clay petals , by Flickr user Spyderella , aka Sharon Cichelli . It flip-flops two of seven LEDs to mark the hours , and gradually illuminates the remaining five at 10, 20, 30, 40, and 50 minutes past . It's controlled by an external Arduino for prototyping purposes , but eventually will be entirely self-contained .

He has a nice gallery of photos detailing the build I'm almost finished painting it , and I just string it all up for the first time since the project exposition to test out the new pickup magnets . It works GREAT So amazing to play something I've built from the ground up . Just have to finish the fingerboard and bridge and then wait for the paint to finish curing so I can buff and polish . it Most of the parts were designed in Open Office and cut on the lasercutter or Shopbot . To make his pickups , he created a magnet wire winder from lego parts and bench power supply .

    : : RepRap : Blog Blog for the RepRap project at www.reprap.org a project to create an open-source self-copying 3D . printer Wednesday , October 14, 2009 Copper Plating Wire Glue I suggested previously that it might be possible to create PCB's by copper plating wire glue to create a low resistance section of track . Also , parts of the glue may be buried beneath plastic to maintain a high resistance , by preventing the plating process in order to make resistors . Anyway , I made a small PCB on our commercial machine , which consisted of a 3mm diameter channel that was later filled manually with the glue . Anyhow , after connecting the PCB to the positive terminal of a power supply and a small copper pipe to the negative , I left it overnight in some copper sulphate solution , with the power supply left at 0.1A higher currents do speed things up , but the results aren't as tidy Anyway , it seemed to work , and after a few attempts there were some important : findings The resistor shown was roughly 10mm l ong and its resistance came to 2kΩ so it looks like wire glue has a sufficiently high resistance to make useful resistors . Unsurprisingly the copper plated sections had a

What Can I Do this is probably one of the most common cries of anguish heard from new RepRap owners . The picture on the right shows two common modes of extruder failure . In each case , the symptom is that the filament cannot be pushed through the extruder , or requires enough force to damage the filament even when the nozzle has been removed and the barrel is hot enough for molten plastic to dribble out of . it To find out what is going on , take the cooled extruder apart and look at the filament inside . If you can't get the filament out of the PTFE or PEEK spacer , the chances are that your spacer has got hot and the filament has bulged inside it . Use hose clamps or a metal sheath to stop the spacer from deforming . You will probably need a new . one If you see a blob of plastic sitting directly on top of the heater barrel , you have a gap . Any space between the top of the barrel and the end of the hole that it fits into will accumulate plastic . This plastic will not all be molten , and will
