c programmer, embedded dabbler, power supply tinkerer. (also loser of three consecutive moderator elections on EE.SE.)

[formerly known as 'madmanguruman' but shed that identity after a nice conversation with Olin Lathrop at Microchip MASTERS 2014.]

almost 15 years experience with switching power supplies at two different companies in the greater toronto area. worked my way from production technician to sustaining engineering, then product development (electrical and embedded). also fluent in vba and labview. currently studying project management theory while working as a power supply designer.

comment Translating SIMetrix/SIMPLIS help into other language
I know what Simplis is - I use it from time to time. It doesn't change my opinion on the suitability of the question for this particular SE site.

comment Translating SIMetrix/SIMPLIS help into other language
I'm voting to close this question as off-topic because documentation translation questions are not under the context of electronics design or repair.

comment should AC ground (earth) and DC ground be connected?
Are you sure the AC/DC power supply doesn't already reference the DC output return to protective earth? Is it a wall-wart or one with a PE connection? (You didn't specify...)

comment Using a “quick connect” terminal for IEC inlet or just soldering the wires?
@gcv It's not recommended to accept an answer immediately, as there is now little incentive for further discussion on the topic now that the acceptance bounty has been paid. I suggest to wait at least 24 hours before accepting an answer.

comment Read the instrument data from printer port directly with computer
Modern Windows boxes don't allow unfettered access to the parallel port without some sort of driver in place. INP and OUTP won't cut it on XP or newer machines. See retired.beyondlogic.org/porttalk/porttalk.htm

comment Antenna Gain definition and uses
This question is going to be closed unless you can clarify what you mean by "delimitation the antenna job" - what do you mean by "delimitation" and what "antenna job" are you referring to?

comment Minimum burden resistor for current transformer
Any additional information should be added to your original question, not in comments. Edit your original question and put the details there - people aren't keen to comb pages of comments to get the details they need to help you out.

comment First PIC Program using PIC16F877A and its configuration bits for Internal clock?
I see that MPLABX v2.26 has 'beta' support for PICkit2 when I set up a dummy project for the PIC16F877A. Try programming it directly from MPLABX instead of with the standalone programming tool. Also, consider investing in a PICkit3 programmer - PICkit2 is largely obsolete these days.

comment PIC UART CODE need help in debugging
MPLAB SIM supports the UART and will allow the output to be redirected either to a file or to a MPLABX window.
