Gene, Never ever wrap static sensitive semiconductors in foil. The point of the pink or black antistatic materials is to 'slowly' conduct the energy from the device or your fingers. Foil is a great conductor and you are more likely to damage them wrapping them in foil than just handling them

Hi Jon, I can buy 100 pieces at $8.622 each in Cdn. which is about $6.15US or $862.20 Cdn total ($615.00 US). http://www.digikey.ca/product-detail/en/DSPIC30F5011-20I%2FPT/DSPIC30F5011-2 0I%2FPT-ND/691581 The US site lists 100 pieces at $5.67 US or $567; a difference of $48.

I second that love for Digikey. It's easier for me to buy from them 9.000 km away from them, than going to a local store here in my country. I usually have the parts in 4 or 5 days and everything is well packed. Also the search engine and order placement is great. A question about pricing on

Re: [Emc-users] Creating G-code?

I was thinking about using "m4". It is a macro processor that is already on every Linux/Unix system and I think all Macs too. m4 will copy its input to its output except when it sees a macro which it will expend. while expanding a macro it can run any shell program or use it's own features. So

In Canada we pay in Canadian dollars and the prices of the parts are suitably inflated past just the exchange rate. There is no minimum and shipping is a flat $8. I'm on Vancouver Island and FedEx delivers the Digikey stuff overnight unless there's been some sort of weather delay. There is no

Re: [Emc-users] collets for this motor?

I can very well understand Gene's feelings :-) This method of fastening chucks was used before self-centering chucks were introduced, chucks weren't supposed to be changed a lot at all. It has been used on dividing heads longer than on lathes and has long been replaced by the camlock system.

Greetings; I had asked about them prior to ordering some hexfet transistors from their site. The cro-magnun filling the order has no clue about the care and feeding of mosfet transistors, so the 10 pack I ordered were arranged as 2 rows of 5, with the legs interdigitated, bound in scotch tape
