    I ordered a strip of 15 GRM033R60J225ME47D capacitors. It's a good thing too. I've never soldered 0201's before. 0/10, do not recommend.

    Removing the old component from the board was a tap of...

    FWIW, I bought some cheap (e.g. $7 for 5 signals) units on eBay. They were the signal head on a brass tube type signals. For the ones I put on the bridge I just carefully removed the head...

    Wired up unit #2 this morning. Noticed one of the diodes is missing! Eek. It still works though with it's 3/4 rectifier.

    Blinking rate is approximately the same. I recorded a 240 fps slow-mo...

    And, with the current conditions, much more random. I would say right now anywhere from 2-8 weeks, some things zoom right out, some things get stuck. I can't find any rhyme or reason to it. The...

    I've been exchanging e-mail with the guy who did my circuit review. He explained it somewhat similarly. For some reason though he didn't seem to think it should be this far off, but didn't really...

    Trying to see if I understood, I went back to my spreadsheet. If I plug in a capacitance value of .6uf (the device is a 1uF, but I think the chart shows it has lower capacitance at 3.3v) I get .498...

    No, I'm not sure I can with it both in the circuit and also being an 0201 part!

    The capacitor is a CL03A105KQ3CSNH, 1uf, 10%. The two resistors that control the timing are both 1% parts, 1M and...

    Seriously, if they don't have the screw, it probably doesn't exist.

    I did some research, both on videos and google. It appears most units flash between once a second, and once every second and a half. So mine is too fast.

    The circuit boards themselves have been fabricated and moved over to the part of the plant that does component assembly. It does not show that all the components are on site yet though. :(
