SUMMARY

This discussion focuses on safely charging a 3300 microFarad capacitor with a 35V breakdown voltage for use in a simple igniter. The user intends to charge the capacitor using a 24V DC source and seeks advice on safe charging and discharging methods to create a spark for igniting flammable materials, specifically for barbeque purposes. The TFC561D component is recommended for generating sparks, along with a hand-wound coil to achieve a spark length of 1/2 inch.

PREREQUISITES
  • Understanding of capacitor specifications, including capacitance and breakdown voltage
  • Knowledge of DC power sources and their safe usage
  • Familiarity with basic electrical components, such as igniters and coils
  • Awareness of safety precautions when working with flammable materials
NEXT STEPS
  • Research safe charging techniques for high-capacitance capacitors
  • Learn about the TFC561D component and its applications in spark generation
  • Explore hand-wound coil designs for effective spark length
  • Investigate safety measures for igniting flammable substances in outdoor settings
USEFUL FOR

This discussion is beneficial for hobbyists, electrical engineers, and DIY enthusiasts interested in creating igniters for barbeques or similar applications, as well as those looking to understand capacitor usage in ignition systems.

Hello,

I have an intention of making a simple igniter. I have a capacitor with large capacitance.
3300 microFarads.
35 V breakdown voltage( i think that is what that voltage means)

I have plans on charging this capacitor with 24V dc source. My question here is, how can I charge this capacitor safely, and how can I discharge it so that it makes a spark on the little electrodes that i plan connecting it to?

Is there a better way to make a simple igniter, but with electricity ? (by electricity only I drop piezoelectric igniters. I do not fully understand their concept)

What are you planning to ignite?
 
Well I plan to ignite something flammable, like few drops of gasoline so that it catches fire and make rest of the stuff burn. What for? Barbeque. I want to push a switch and ignite my fire on the barbeque.

Please don't judge me XD I am just bored
 
Get the datasheet for the TFC561D. You can use this and a hand-wound coil to make 1/2 inch long sparks.
