... You can use a Op amp circuit to make one that will display on a scope. Matching devices is tricker than just using a curve tracer since there is...
Is anybody interested in this robot arm? Dear a member of TCRobots, I am a PhD student in University of Minnesota. My advisor likes to donate a an Intelidex...
Bill, I have a batch of new transistors, all same part number. I need to match them for Beta only. Multiple devices are used in parallel in the output section...
I have access to a Tektronix 575 transistor curve tracer if you'd like to use it. I have not used it myself but its operation should be straightforward....
Thanks Tom! I will get in touch soon. ... From: tcrobots@yahoogroups.com [mailto:tcrobots@yahoogroups.com] On Behalf Of Tom Baraniak Sent: Monday, December 11,...
Hi gang, I keep running into the same need: coupling this sized shaft to that sized hole. Again and again, I wish I had a small lathe. Well, 'tis the...
Bruce, If you want easy to set up and use, you probably shouldn't go with any of the Sieg lathes (sold by Harbor-Freight, Grizzley, and many others). They are...
... I've had my eye on one at Ambles, but I don't have the money :( Then again it's 12 feet long and probably weighs several tons. I always liked "old and...
Bruce, I have pondered the same thing, so the conversation has been good. My father suggested that I look into used tools. In the Detroit area there are lots...
Thanks for the helpful responses, all. Someday, I believe I will own a respectably large metal lathe-- but right now, I'm in the middle of a move and if my...
... First off, it's safe to plan on spending as much on tooling (chucks, cutting bits, measuring devices, boring tools, tapping tools, etc) as on the machine...
HI Bruce, ... I have a Sherline, which is very nice, but I've often wanted something just a bit bigger. For the Asian lathes, the only one I would consider is...
Bruce, One thing you might consider depending on your needs is using a mill as a lathe. A few years ago there was a series of articles in Home Shop Machinist...
Well, I guess I'll chime in. I've been lurking on this group for almost two years now, learning a lot by watching you all talk, so it's probably time I give...
I am trying to decide which is easier to implement. I need to sustain 500K bytes/sec with a maximum latency of .5 seconds. Options 1. High speed USB (480) 2....
Bill, To me, it looks like 3) should get you what you want with the least pain. With one requirement - that this device is the only thing on the bus. (if there...
Dear group, My family says I need help, and after some soul searching, I've decided they're right. We just started the process of getting our suburban home ...
SWEET! I will be making this meet for sure then! Dave ... From: tcrobots@yahoogroups.com [mailto:tcrobots@yahoogroups.com] On Behalf Of Bruce Shapiro Sent:...
... Welcome to junkaholic's autonomous. I'll bring a cart to bring home what's left. I'll take anything with aluminum or steel as I am building a forge. My...
... Hooray. :) I found a way to reduce the data size so I only have to sustain 250K bytes/sec forward and 512 bytes/sec reverse. Next. I can ensure that the...
Wow, what an odd 2 years here. I moved from Eau Claire to South Milwaukee/Franklin area. MAKE Magazine had me on the front cover with 2 other Illinois droiding...
... We are going to be using (literally) thousands of MCF52223 processors in an upcoming machine. We have much more strict USB speeds and latencies than you...
... Perfect! ... Yes, but I have a few too many. Plus, now that I've converted to servo-worship, I'm not feeling so stepper-bound. ... Have you priced metals...
I'm interested in some aluminum for use on my mill, if any of it is suitable for that type of application. As for steppers, I wanted to modify my mill for CNC....
Bruce, Do you still have those mills for making orthodontic crowns? I would love to have one of those. I can even drive over to your house to get it :) Did...
