Xenon Timing Light
That explains why it’s a bit iffy when I measure it. My local has 2, but they don’t tell you much. 1 - Pri-500Ω 3 wire and Sec-8Ω 2 wire...

Old_Grey: So that’s how you work out transformers. This is 1-ish ohm to 14-ish ohms - my DMM doesn’t seam that accurate - but my cheap Ebay transistor checker shows 3.2mH to 32.8mH which is close to...

Even at 55V it makes a pretty big zap, so 300V is a lot. I might not release this one to the Speeduino forum if I get it working because parts aren’t easy to find, but I still have to make a compact...

Micro sdCard Part
In another link, I posted info on the sdCard Adapter I use (senmod sdhc adapter). I’ve used them enough now that I decided to make a ‘Part’ for it. Info: • I like big pads so, the pads are for my...

Old_Grey: EDIT - I just realise it might not work because the energy released from the flash interferes with cameras. A metal box (grounded) around the flash may help with that if the energy is being...

Looks good other than the pins in schematic aren’t on the .1 grid which most of the other parts are. It will work fine as is but the connecting lines to other parts will be bent a bit in schematic....

Thanks. That’s weird!! I figured out what happened… Inkscape changed the units from inch to px when I re-opened the file and the dim’s shifted… I reset them to be 0.1". It looks correct in the...

Yep that looks to have gotten it. I’ve been bitten by that more than once. When you save the file (and sometimes when you change between drawing elements I think) Inkscape changes back to px as the...

Should be able to do a metal plate. I just realised I need an rpm display in the vid, ouch! Looks like the 240V to 5V wall wart trans isn’t any good. It’s ferrite core and has 3 separate windings :- 1...

When I was young and built hot rods the only timing light we had was one that ran the Xenon bulb directly off of the coil voltage and went inline with the plug wire (no induction coil). I tried to...

Actually an in-line timing light was my first too, and yes it’s not as bright as my next cheapest clamped TL. I reversed my el-cheapo, but it’s too expensive to build compared to an Ebay one. From...

I may have a source of cheap circuits you could use for powering a timing light. Electroluminescent wire inverters. They run around 100vac so would require a rectifier. www.banggood.com Controller...

In this instructable about a diy mains powered timing light he uses a voltage doubler followed by the circuit you last posted. It looks like you wouldn’t even have to rectify the output from an EL...

If you want another option for really cheap HV power supply you could look at CCFL inverters. You can get ones designed for CCFL headlight rings designed to work off 12v. That say 5-8ma output at 900v...

The CCFL for $4 looks promising if you can turn it down internally without a transformer. The other LED circuit didn’t seam to have lag when compared to my Xenon light - the leading mark looked...
