  1. Someone over there uses Tyll's avatar as well... isn't that a picture of him and his test box?
  2. My brother sent me one of those stands last year. Works well. Wish I had their workstand. Glad I don't have to use a workstand that much though.
  3. You can hear hum with the headphones on your head, but them not being plugged into anything? And this hum is coming thru the headphones?

    Happy Birthday Al! Hope it's a great one!
  5. Cool Vicki! ShimaNO... sorry, couldn't help myself Can't wait to see it!
  6. My brother and his wife stayed at the Hyatt Regency a few years ago down on Michigan Ave. on Wacker... easy walk to the Mag mile. Another friend stayed at the James hotel on Ontario, 1 block from Michigan Ave. and said it was good. Not sure what pricing is like.
  7. You may find some overlap in hFE when you test them between grades. Or not. If matching, I you can see what matches up and use those. No difference in the parts, just graded during testing by the manufacturer.
  8. ^ Just eat one less biscuit to compensate...
  9. Frogs have a huge amount of float (20 degrees to release outward, 6 degrees inward) which would make them a no go for me (I hate float). I have a hard time releasing outward on my right leg, which is the one I unclip, so I normally go inwards to unclip. I know, you're supposed to go outwards... You would need to try some pedals to see what you prefer as far as float, release, etc. EDIT: and true dat what aerius just said... ride it.
  10. Justin, Maybe just start out with some Powergrips on the stock pedals (not sure what those are). Either that, or put some toe clips on, though I don't know how well those will work with non-smooth soled shoes. Might be hard to get into.
  11. JAE makes some pretty decent connectors. These were used for the HV umbilical on a Counterpoint preamp I used to own. Check the voltage rating though if you need above 300V or so (though mine was running at 425V... good designer ) http://se.mouser.com/ProductDetail/JAE-Electronics/SRCN6A21-16S/?qs=sGAEpiMZZMvwyOPDUMfDH5gn%2fEwOZw6DcRDCXriNW8o%3d http://se.mouser.com/JAE-Electronics/Standard-Circular-Connector/SRCN-Series/_/N-1z0zl5cZav49jZ1yzvw9y
  12. Cool! Also, forgot, nice bike for Peter!
  13. Re: servo There was an amusing thread on HF where Rudi (rudistor) got into it with Kevin claiming that the servo was feedback and bad... the servo operates under 1Hz, so I guess it is somewhat
  14. Jim, Is Peter also using the Bridgestone you and he refurbed? Or was that for you
  15. The DC servo really isn't a feedback circuit. However, thinking about it, you do have the negative feedback in place, correct? Don't have the resistor numbers offhand, and I think the 2pf cap is compensation for the feedback circuit. You might just pull an active of each type, or if you have spares, test them. EDIT: R52/53 and 56/57 are the feedback circuit, with C1 and C3 as compensation caps (schematic shows 1pf).
  16. Happy Birthday!
  17. Happy Birthday!
  18. Agreed. The bouncing around part and the amount that it is moving seems to indicate a problem. For something like an I/V stage with no feedback, I see this. For a dynalo/dynahi, they normally seem pretty stable for offset if things are correct in the build, pretty stable meaning it should be easy to get it to +/- 2mV drift without the servo in place..
  19. How is your heatsinking? The output devices need to be thermally stable, although even with that I don't know that you would see 5V output DC offset. I'm not sure if there is an operating points diagram floating around, but it sounds like you may have a wrong part somewhere. Also, the LEDs should be matched pretty closely for V drop.
  20. It took them 4 times to ship me the correct resistor value on an order a couple of months ago. They must have had the wrong values in their location. I had ordered 2.2K RN55s. They sent me 3.1xK the first 2 times. I changed to a 2.21K, they shipped me something else. Finally got it right, but yeah, they seem to be having some problems. I don't think before this that they had ever made a mistake on any of my orders. The other 20 some line items were correct on the latest order.
  21. Road 6 miles after work on the Trek (Raleigh is still in pieces ), 33 degrees, not bad. Still need to make some adjustments to the Trek, like wider bars than the stock ones. Also need to get something else on this for pedals as the platform ones on it suck. It has been so long since I have ridden without some type of foot retention that it feels really awkward. Feet slip all over these things.

    ^ build a dynalo/mid
  23. Pigmode, hope your back mends quickly. Vicki, take it easy as Chris said. Give it some time before you work up to steeper climbing. Me: Bought a Campy Racing T crankset and Centaur BB (not pictured). Will use these on the Raleigh late summer for something I don't know that I can climb in a 43-24.
  24. Happy Birthday Fitz!
