[Today’s run: 7 miles\u00a0 (Oktoc Road)]<\/p>\n
Today I finally finished putting my LC meter in a metal box.\u00a0 Also, I removed the\u00a0 9 volt battery so it will now need to be powered by an external DC supply between 9 and 15 volts.<\/p>\n
I also made a little fixture which I am hoping will help me measure surface mount (SMD) chip capacitors and inductors.\u00a0 I made it from double sided PCB material.\u00a0 It remains to be seen if the fixture has too much capacitance to do the job.<\/p>\n
I also worked with my HP 400E AC Volt Meter a bit today.\u00a0 I sprayed some lube on the big ganged range switch and I was trying to compare it with the W7zoi watt meter which I built a year or two ago.\u00a0 Reading the 400E is much more challenging.\u00a0 It kind-of\/sort-of agreed with the digital watt meter.<\/p>\n
I got a shipment of parts last week and tried my most recent swap on the old year-long broken O-scope.\u00a0 I really miss that thing.\u00a0 I now have a half-baked scope which sort-of works.\u00a0 My problem with the broken one is in the power supply and I’ve been throwing parts at it to try it make it happy.\u00a0 That isn’t working.\u00a0 I may have to actually try to figure out how it works.\u00a0 I do not have a good repair history with broken oscilloscopes.<\/p>\n
A week ago I spent a whole day trying to get the SI5351 signal generator to have two outputs on one frequency with one of them inverted.\u00a0 The status bits say that it is inverted, but it doesn’t show up on my half-baked scope as inverted.\u00a0 I’m not sure how to prove that the generator is wrong and not the scope.<\/p>\n
