Learn to Solder with Prof. Potter - Bluetooth Speaker Kit for Beginners!

See https://steveMpotter.tech for my maker courses in Ireland and Northern Ireland. Here, I demonstrate and explain every step in the assembly of a very inexpensive Bluetooth Speaker soldering kit from the All Modules store on Aliexpress. This tutorial is aimed at those who have never soldered before, but anyone with a similar kit will benefit from the details I convey. Just use the timestamps to go to the part you are interested in, or are having trouble with. The soldering (Das Blinkenlights circuit) is all "through-hole" soldering, so it is pretty easy. The Bluetooth module (preassembled) that does all of the sound can also play MP3s from a USB memory stick, and the kit comes with an IR remote that you can use to adjust volume and EQ. It has about 7 different sound options. I think the best one was from pushing the EQ button twice. Here is a link to the kits I got, but you can find a similar or identical Bluetooth Speaker DIY Kit from many vendors on Aliexpress, so you may wish to shop around. Hint for searching: many of the Chinese-English descriptions of soldering call it "welding". https://www.aliexpress.com/item/10050... 0:00 Intro 0:21 Unbagging 7:53 LED pointing advice 9:30 Order of assembly 10:14 Parts sorted in egg cartons 10:54 Peeling paper off the acrylic enclosure 12:45 Altman's "Soldering is EASY" booklet https://mightyohm.com/soldercomic 13:34 Heat up the leads and pads, not the solder directly 14:05 Tools; Soldering iron, solder, tinning, smoke, 3rd hand, magnifiers 15:17 Resistors 15:42 Resistor colour code guide https://docs.google.com/spreadsheets/... 17:28 Bend leads and insert 19:11 Good solder connection closeup 19:21 Trimming wire leads with flush cutters 21:56 Keep iron tip wet with solder for good heat transfer 23:29 Start small 23:43 Transistor soldering 24:43 Electrolytic capacitors are polarised! 26:44 microphone soldering 27:10 Trim potentiometer soldering 29:17 Counter IC chip, bending leads 30:48 Blu-Tack to hold things to PCB 32:19 LEDs soldering 36:08 Jumpers soldering 37:10 Power wiring - 2A 5VDC power supply is best 38:53 Split, strip, twist, and TIN! 42:59 Connecting the switch 45:43 Heat shrink insulation 47:39 LED PCB power wires connections 50:47 Speakers soldering - intro 51:09 Speakers are polarised! 51:50 470uF capacitors on speakers 56:47 How the parts go together 59:02 Post-soldering assembly 59:41 Bolting speakers to side panels 1:03:00 Final assembly begins 1:03:49 PCB mounting 1:04:41 Hot glue for nuts 1:05:38 Final final assembly 1:08:15 Don't overtighten standoff screws! 1:09:05 Testing finished Bluetooth Speaker 1:09:40 Bluetooth pairing - use YM069 1:10:07 Use EQ button for better sound quality 1:10:35 Adjusting the trim pot to get good LED action at desired volume Music: Taurus (Instrumental) by Dylan Charbeneau
