  1. Test..test..test The first image is with Copy/Past in Firefox 39/Windows7 Pro But didn't work. the second (Monostables) was with "Choose files"
  2. http://www.5bears.com/welder.htm is one. Mine: http://metalworking.com/Dropbox/_2001_retired_files Look down the list for five "Miller Time" files Ken
  3. One of the most amazing uses of electronics in farming to me is the real-time control of fertilizer delivery and planting based on variations of soil conditions and GPS location over a field. Ken
  4. Pandit, Simple resistance/conductance detector circuits for water do not work with hydrocarbon fuels. The these liquids are not conductive. Ken
  5. mbalegria, Your question has nothing to do with this thread. You should start your own thread with an appropriate title to get helpful responses. Ken
  6. Because you needed to ask, and because I have no idea of your service entrance box configuration, I strongly recommend that you have an electrician do the check and any repairs. Ken
  7. That is a symptom. What's the voltage at the two circuits in the circuit breaker box entrance. You need to have an electrician check all the connections at the service entrance and circuit breaker box. Ken
  8. Likely, you have less than good neutral connection at the service entrance box or the utilitie's transformer. In the US the service supply is from a 220vac center-tapped transformer. Half the circuits in a house are supplied 120VAC from neutral to one end of the transformer's secondary, and the other half are supplied 120VAC from neutral to the second end. If the house neutral to transformer's center tap is lifted, the devices on the two circuits appear in series and become a voltage divider. If both circuits are equally loaded, each will see 120V. But if not, the circuit with the lowest resistance devices (more heavily loaded) drops proportionally less of the 220V across its devices. The circuit with a higher resistance (less heavily loaded) drops more. So, when you short out one circuit, most or all of the 220V appears across the other circuit. The bulbs on the other circuit see a supply voltage much greater than 120V, get brighter, and then burn out. I saw this in my parents house. Ken
  9. How about showing us what you're doing...schematic?...voltages?...frequencies?...component ratings? ????? Ken
  10. Check these segment addressable recorder/playback chips: http://www.nuvoton.com/hq/enu/ProductAndSales/ProductLines/ConsumerElectronicsIC/ISDVoiceIC/ISDChipCorder/Pages/default.aspx Ken
  11. And even if you can assemble a circuit with a resolution of 0.001
  12. Not only would the sensors be expensive, but the electronics with enough resolution "and" stability will be incredibly pricey. :( Ken
  13. Schematic, free: http://www.nostalgickitscentral.com/eico/schematics/eico_schematic_1050.pdf Manual, on ebay: http://shop.ebay.com/items/EICO%201050%20manual Ken
  14. Have you Googled: e square u10 chip u10 sounds like a 'schematic drawing label' for an integrated circuit chip, not the chip manufacturer's number. From my Google-ing it looks like "e squared" may be a double-e prom...electrically erasable programmable read-only memory chip. Do you have access to the schematic or to the circuit board? The equipment manufacturer should be able to give you the chip manufacturer's standard number for the component. Ken.
