Thanks.This answered a few q's I had and brought me up to speed with soldering techniques. Have to agree with JRD that the chisel tip is a better option.
Just a little tip (excuse the pun): use a chisel tip on your soldering iron. It will transfer the heat much better, those conical tips supplied with the iron are pretty useless.
If used properly, little tips go a far way! Nice point - it would be more effective to use the chisel in this case because of the wider surface area & better heat transfer! I have seen these used and will have to pick a few up. I know that most soldering irons (including mine) have a way to replace various different kinds. But, if you only got the conical it is good enough to get the job done!
WaveShapePlay Finally, somebody who can have a constructive conversation on UA-cam. If you search eBay for chisel tips, you will probably find a load of cheap tips. They usually come in assorted sets. Plus they are almost always below £10.
Hey there! I appreciate your detailed tute here! I have a question for you, since you seem quite knowledgeable...I have piezos that I am using to solder to female ¼" trs jacks, solely because I purchase an Alessis DM Dock for my e-drums. However, the piezos are pre-wired - 1 black and 1 red wire. The trs jack has 3 posts on it so I am not sure which wire to solder to which post! I would be most grateful to you if you could advise me on this! And thank you ahead of time for your time! I Hope All Is Well In Your World : ) Nyna
Hello boss.... I have headphone 4 step pin and a mono jack cable now I want to connect to mono jack cable to headphone pin......... 😀but in mono jack it's have only two wire and in headphone pin it's has 4 wire.... How to connect it...... 😁😁
I have a question about the xr2209 I have build the example circuit from the datasheet but my circuit starts heating up after some time and it starts to smell like toaster and the frequency decreases as well. I am new to the world of electronics so I am completely clueless what causes this heat. Do you know what might cause this?
No worries. The heat is caused from drawing too much current (power). The chip is designed to handle a certain amount of current - when too much is current is drawn the excess power is dissipated as heat - i.e exceeding the current range specified in the datasheet. power = voltage * current A few general tips for when your ICs heat up. 1) Check power supply range (or battery) versus the datasheet's limits 2) Double check that you hooked the single or double supply topology (circuit layout) 3) Check output load - most things have a hard time driving a speaker ~4-8 ohms. If you hooked the XR up a speaker directly you need to buffer or add additional amplifier circuits that can drive the speaker. If you are measuring with an oscilloscope no worries here - only if you are driving a small load. 4) If you use a variable resistor as the timing resistor make sure not to exceed the range in that datasheet (see below). I would stay within the 4k to 200k range to be safe: Add a ~4k resistor in series with the variable resistor to make sure you do not go under the minimum threshold. From the datasheet: Page 5: Pulling excessive current from the timing terminals will adversely affect the temperature stability of the circuit. To minimize this disturbance, it is recommended that the total current drawn from pin 4 be limited to 6mA. In addition, permanent damage to the device may occur if the total timing current exceeds 10mA. Page 6: The timing resistor determines the total timing current, IT, available to charge the timing capacitor. Values for the timing resistor can range from 2k to 2M; however, for optimum temperature and power supply stability, recommended values are 4k to 200k (see Figure 8, Figure 9, Figure 10 and Figure 11.)
Sorry, you are teaching a bad technique of soldering, bro. It can make your socket pins are less conductive anymore. Or the isolator between tip and sleeve becomes melting.
Literally the only good video of this on the internet. Thanks!
I solder about once a year. Thanks for the reminder.

I appreciate the advice, there is always more to learn! Will do - thank you Joshua

Btw wrote this on my mobile phone so I am sorry for the grammar mistakes
No worries. The heat is caused from drawing too much current (power). The chip is designed to handle a certain amount of current - when too much is current is drawn the excess power is dissipated as heat - i.e exceeding the current range specified in the datasheet.
power = voltage * current
A few general tips for when your ICs heat up.

From the datasheet:

To minimize this disturbance, it is recommended that the total current drawn from pin 4 be limited to 6mA.
