High voltage ignitor/igniter unit
Added 2022-10-13 04:27:32 +0000 UTCI appear to be making a video almost every day at the moment. I'll have to tame things down to avoid having a huge delay between videos being made and released on YouTube at the usual schedule of one every two days.
This was a pretty cool unit. Very sparky and poppy, but with very simple circuitry.

2022-10-22 15:50:59 +0000 UTCThe resistors will limit the current and it will reset when the capacitor has discharged and the mains waveform passes the zero crossing point.

2022-10-18 20:26:59 +0000 UTCWon't the sidac shunting also cause a huge current on the AC side (through the shunt)?

2022-10-15 03:19:28 +0000 UTCOnly 1/2 fill the bottles, I use the same bottle for sewing machine oil, providing it is not nose down it will not leak. (time slot 4.27)

2022-10-14 18:38:43 +0000 UTCYes, but rated for much higher current and with selectable trigger voltage.

2022-10-13 17:48:28 +0000 UTCIt probably does. I should really stop grinding and dremeling stuff at the bench. I managed to cover everything in the vicinity with Tesla-dust from the headlight video.

2022-10-13 17:47:56 +0000 UTCUnless the sausage were in an explosive atmosphere. Sounds like fun. How many joules to cook a sausage to perfection I wonder?

2022-10-13 17:27:05 +0000 UTCIs a SIDAC the same as / similar to a DIAC, as typically used in TRIAC trigger circuits ?

2022-10-13 16:54:07 +0000 UTCThe power output is miniscule. Nothing would happen to the sausage.

2022-10-13 16:12:57 +0000 UTCThe neon was probably being used as a charge threshold detector to trigger a thyristor.

2022-10-13 16:12:17 +0000 UTCThere's no real way to opt out, but you can ignore the live stream posts and not view the streams.
Big Clive
2022-10-13 16:11:47 +0000 UTCI enjoy the devices and teardowns - they're very informative. But I would like to opt out of the live streams - not really interested. Is there a way to opt out? Thanks!

2022-10-13 15:08:29 +0000 UTCThe ancient gas boiler in my old house used a neon in some kind of relaxation oscillator circuit to produce the sparks.

2022-10-13 12:58:48 +0000 UTCPlease repeat the spark test but lay a sausage along the wires first.

2022-10-13 10:59:32 +0000 UTCKeep making the vids as you find natural; if there are too many, you can keep some back for releasing at times when you want a bit of 'me' time.

2022-10-13 10:54:23 +0000 UTCI have wondered how the cooker managed to spark everything at the same time- very interesting bit of kit.
