Hello,
I am in the process of repairing some legacy equipment that uses the V850/SB1 series of mpu from NEC (now Renesas)
The device is the UPD70F3033B - and in the situation the on chip flash has become corrupted and needs to be reflashed (self program will not function). I have an...
Hello,
I'm working on a piece of furniture, and according to an FEA study one of the parts (the lower frame) needs a yield strength of roughly 65,000 PSI to pass certain certification tests.
There are two versions of the chair, one made from mild steel and the other from stainless steel...
Hello,
I'm working on a lounge chair design, and the client wants to use stainless steel for the frame elements, as they like the appearance. However, they also want the elements very thin (again for appearance).
My question relates to spring tempering 301 or 304 stainless barstock. The...
Hello,

A 6 pin mini DIN is too large (about twice the size that we want.)

I'm working on a project where there's an ID person using Alias, a surface modeler. As the design has grown in complexity, I don't seem to be able to use her surfaces to crate a solid body. She is giving me IGES files.
She could give me STEP instead, though I don't know if this would help.
My...
I've read some concerns here over Unfrag or ecosqueeze, and thought I'd mention an alternative.
In addition, this alternative can fix corruption problems. For instance, I had some corruption that prevented the circular pattern feature from working correctly, but using this procedure fixed that...
Here's a question that came up recently. I'm an independent consultant/designer. Recently one of clients asked if he could have the actual part files from my CAD program, in addition to the IGES and STL files I planned on giving him.
My general instinct is no not deliver the part files, as this...
