1. Will you guys who have been around forever please take pity on me and tell me how you used to use an old-fashioned, free-standing oscilloscope to examine the spark on an engine? What kind of attenuator would you use, and what sweep rate?
2. What do you think of those "paint-can" smoke machines that are sold on eBay for around $65 or $70, and which one is your favorite?
