Hi Primarygun, First, what type of multi-purpose printer is it? e.g. HP deskjet 355X. Second, what is your computers OS; Windows98, Me, XP, NT? Third, what type of cartridge is it? single color black, or tricolor? Fourth, how is your printer connected to your computer? USB, Parallel Port (LPT), or network print server? Meanwhile, until I receive a response to the questions above, you can try the following for possible quick fix: If you are using Windows 98, Me, XP, or NT goto control panel, select printers: 1) Verify your printer is the default printer (the printer icon with the check mark). Fix: If not the default, right-click on your printer icon, select default from drop-down list, and left-click on 'default'. Your printer icon should now have the 'check mark' designation. If not, repeat until it does, refresh the screen and/or browser if necessary. 2) Now verify your printer settings: once again from the control panel, select printers: select your printer icon (the default printer with check mark), right-click and select properties. Once in properties, verify all settings: printer port (select appropriate USB or LPT), paper-type, paper tray, etc. Then check your ink settings: if possible, check 'new ink cartridge' installed settings, or Reset ink level option, etc.. 3) Last option, RE-BOOT PC. Shut-down all open windows. Then shut-off the Printer power. Next, shut-down windows normally (click-on Start, Shut-off Computer, Shut-down). Wait at least 30 seconds, then FIRST turn-on your printer. Does your printer give an error? (e.g. out of ink, paper jam, etc.) If so, follow the printers procedure for replacing ink cartridge -- remove your old inked cartridge and then replace it again. Once the printer error is cleared, shut-off printer, wait 30 seconds and power-on the printer again. This time you should not get an error. If so, repeat until error cleared. If and ONLY if, you do not have a printer error, then power-on the Computer. Once boot-up is complete, launch Notepad (but not Word or Wordpad). Then type in a sentence or two, and try printing. If your Notepad text file prints normal than the problem is probably fixed. If the Notepad text prints correct but type is thin, light, or jaggered, then run the printer 'clean head' procedure from: control panel - printer, properties - clean head setting. If it is a network printer, then let me know because this is more complicated and requires knowing your print server IP address, your printers Ip address and all other network computer devices IP addresses. You can get this info from your network admin.. Then resovle any and all IP address conflicts -- e.g. never use an address with all O's or all 255 (F's), this is broadcasting and you will most definitely jam the network. Hope this helps, it is a long drawn out process but this should cure the problem. If not, buy a new cartridge, install and check print. If the problem goes away, then most likely you trashed the old cartidge by touching the cartridge circuit boad (static zapped). In which case, the old cartridge will never work again, no matter how much ink you force into it. So, toss it out. Also, if you scotch-taped over the bottom opening of the ink cartridge while filling from the top, then you might have clogged the sponge with glue -- again, this is taboo and it is probably trashed. Good Luck, let me know if this helped.

Hi Labview1958, Regarding your #12 posting, Faraday disk generator using hollow copper ring ... Q. Is there a metal ball inside the copper ring which is allowed to move upon rotation? Q. Is the rotatig hollow copper ring's radius parallel (preferred) or perpendicular to the external magnet? From the diagram, it appears to be perpendicular. Q. Where are your two termination contact points located? Q. What is your reasoning behind using a 'hollow' copper ring? How do you believe this will improve the eddy current effect, as ooposed to using Faradys flat copper disk? Q. Are you familiar with electric-magnetic breaks? Q. In what way do you believe the hollow copper ring will show drag? This is an interesting design.

Hi Labview1958, I am not a skeptic, nor a critic but an alternative energy advocate, research engineer and scientist seeking answers to these most difficult questions. I hope to find like minded individuals, perhaps together we may find the soultions. In regards to your posting #10, to re-create Faraday's homopolar disk generator using HTS SC's instead of a copper disk: replacing the copper disk with a HTS SC is not a novel idea, this has been suggested and explored before. But, there are many complications with this idea, such as: First, Faraday's copper disk produces its current output as a result of an external magnetic field causing eddy currents within the copper disk which is rotating in fixed orientation such that the magnetic field is perpendicular to the radius of the disk. Current flows from center axial pivot point (termination contact 'A'), through the copper disk to its outer edge along its circumfrance (termination contact 'B'). This differs from using a HTS SC disk: since it does NOT rely on eddy currents, but instead current flow increases with decrease in temperature thus producing the Meisner effect (which requires an LN2 catalyst to invoke). As a result of achieving the meisner effect, the HTS SC provides many useful benefits; e.g. magnetic levitation, low resitivity and high current capability. Difficulty arises from cost, size, quality of material composition, and ease of use (LN2 is tricky to handle), etc. Secondly, if given a "perfect" machanically built apparatus, the HTS SC would most surely out perform the copper disk. Unfortunately, creating such a perfect device is easier said than done! Perfection is not always obtainable, and even when possible it is very costly (e.g. Hubble Telescope). Inherent to the functionality of the homopolar generator (copper disk, or otherwise) is the ability to tap the current from the high-speed rotating disk. The two most widely used methods for the copper disk are: (a) solid carbon contact, which suffers from wear and surface contact irregularities, and (b) liquid mercury bath contact, which is difficult to contain not to mention the difficulty to maintain liquid level and surface contact. Third, if either of the two termination/contact methods mentioned above are to be used, would not their excessive contact resistance and wasted frictional heat defeat the sole purpose and benefit of using the 'low resistive' HTS SC? So, copper -vs- SC disk? I'd say, go for the SC disk. The end result of increased current flow appears to be the same, but for entirely different reasons, methods and practices. Aside from the difficulties in building a functional HTS SC aparatus, the homopolar generator ulitimately suffers from one key design difficulty: "termination contact". That said, what do you suggest would be more appropriate in providing an alternative termination contact material and/or method for the suggested HTS SC disk? Lastly, how do you maintain constant LN2 contact and temperature to maintain a steady current flow? This is the most difficult question.

Hi cessna7686, Cornell, excellent academic program. Are you a team member of the (N C M R S ) Non-Contacting Modular Reconfigurable Spacecraft Project? If so, then you are actively involved in the actual design of the HTS device itself -- to further exploit the flux pinning effect, or at least are having it made to your exact specification to do so. That being the case, then I do not want to mis-guide your efforts in suggesting the sole use of non-SC diamagnetic devices, or even room temp SC (RTS) devices for your application, as I'm not sure if the alternate would provide a beneficial increase in the flux pinning effect. Your project sounds intriguing. If possible, I'd like to hear some more about the potential 'applicational uses' of N C M R S.

If I understand you correctly, what you are attempting to do is disprove Earnshaw's Law by creating a diamagnetic field in which you can vertically trap/suspend (a.k.a. levitate) a superconducting (SC) magnet (although horiz. positioning will be intrinsicly unstable). In fact, it is possible to disprove Earnshaw's Law by using "diamagnetics" (e.g. bismuth, carbon, pyrolytics) by replacing your SC magent and LN2 tube with a simple non-superconducting NIB magnet. In doing so, the geometry of your experiment is greatly reduced as follows (note: adjustment is very tricky and tedious): wooden vertical & upper overhead support (non-metal) 6 or 8 Donut-shaped Rare Earth Magnets (suspended from above support by bolt/nut) adjustable air-space (approx. 4-8 inches) diamagnetic material (bismuth, carbon, pyrolytic) (nylon spacer) -- NIB magnet levitates here -- (nylon spacer) diamagnetic material (bismuth, carbon, pyrolytic) wooden base (non-metal) Levitation of non-SC magnets is that simple, and total cost should not exceed more than $25 USD! Goto: http://www.forcefield.com , and check-out their experiments section, under "diamagentics". They supply all types of magnets, and also have small kits for building a diamagnetic (pyrolytic) levitating train!!! Problems with using SC to duplicate the above levitation experiment: First, type-2 SC magnets can be very costly (depending on specifications) and LN2 maybe low cost but is very dangerous to handle (special equipment req'd; Dewars Flask, low-temp gloves, etc.) even if LN2 is safely contained. Secondly, Type-2 SC require near zero temp. and the flux pinning effect may cause both unstable vert. and horiz. levitation -- unless SC is made to rotate about its axis and/or an electromagnetic control circuitry is used to stablize (see similar device used on non-SC toy called Levitron Anti-Gravity Top; available from Edmund Scientific's Spring 2005 catalog, p.89, or goto http://www.scientificsonline.com). Does your application absolutely require using SC with LN2? Are you opposed to using non-SC diamagnetics at room temp. for levitation?, or are you just unfamiliar with these non-SC materials (bismuth, carbon, etc), and diamagnetic levitation procedures? What is the nature of your work? Is it antigravity craft?, transportation levitation?, or alternative energy prime mover related? Perhaps, I can be of some help to you. D-Noonian :)'

Have you considered Room-Temp Semiconductors and/or diamagnetics as an alternate means of creating the 'flux pinning' effect?

Hello Bio-Hazard, First, you must maintain at least a 3.0 GPA in college and pass ALL math (algebra, pre-calac, calc-I, calc-II, differential eq, probabilty & statistics, etc.) with a minimum of 'C' -- some colleges required no less than 'B'. You will need to also take courses in psychology (i.e. Pavlov on Behavorism), anataomy and neurophysiology such as Biofeedback certification: brian;EEG, heart;EKG, muscles; EMG, eyes; EOG, skin temp.; GSR, etc. (check-out these organizations: BCIA , BIOF, http://www.mindfitness.com, http://www.wilddivine.com, and http://www.behavmedfoundation.org for industry certs and tools). The field of Cybernetics was pioneered by Norbert Wiener -- his books on 'feedback systems' are difficult and dated, but a good reference none-the-less. Today, the field has many pioneers split into two methodology camps -- software and hardware (the connectionists). New VHDL Field Programmable Gate Arrays (FPGA) chips has allowed the connectionist to surpass the softeware barrior of 100-1000 neurons -- producing 40,000 neurons on a single chip!!! (de Garis is approaching 100,000 neurons in real-time!!!) So, if you are serious about the 'Johnny Mnemonic' brain booster, then check-out: Proffessor, Dr. Hugo de Garis' work on "Brain Building" using VHDL-FPGA's called the CAM Brain Machine (link: http://www.cs.usu.edu/~degaris/). You could study here in the USA, at Utah State University, Logan, Utah, directly under the professor, check-out the many 'on-line' study guides he provides --they are sure to jump start your brain! In addition to Cam Brain architectures, you'll need to have familiarity with electronics hardware; firmware programming, transistor and op-amp feedback circuitry for mimicing the neuron, Boolean digital logic, and fundamental Robotics. As for software, you must know Basic, VB, and C/C++ at a minimum, plus an understanding of: "Evolutionary Computing", "Genetic Algorithms", and Chaos Theory (mimicing the patterns of life; neurons, tree-branching, phi spirals, etc.). This can seem overwhelming at times, and it can be, but it is doable -- it has been my life for the past 25 yrs. Its never too late to get started. Let me know what you think of Prof. de Garis and the Cam Brain. Hope this info can be of help, or at least motivating. Hey, are you familiar with the biofeedback device by Wild Divine? If so, please let me know. Thanks.
