You don't need to do any soldering if you get the right parts. Get these leads to connect to the header on the rpi board. Then get these connectors and you’ll need a 4.7k ohm resistor. I’d suggest buying a combo pack of resistors and save the other resistors for future projects.

Pull two of the F/F leads off from the rest and cut them in half; you’ll use 3 of the 4 resulting pieces. Connect one of the leads to the Vcc lead on the thermometer probe (usually red) and one end of a 4.7k ohm resistor. The connector/splice is a T so you’ll use all 3 connections. Then connect another of the half leads to the Data lead from the probe (could be yellow or white or almost any other color) and the other end of the resistor. You’ll have something that looks like an H with the two leads with the resistor across the middle. The third lead from the probe will be the ground lead which will probably be black. This lead will be straight through just joining the resistor probe lead to the lead with the gpio header female to connect to the rpi board. The end result should be 3 wires terminated with the female header connector and the resistor between Vcc/Power and Data lines. Now you are ready to connect to the rpi board. Make sure it’s powered down and locate pins 1, 7, and 9. Look here for a diagram. Pin 1 is the pin closest to the SD card. Pins 1,7, and 9 will be the first, fourth, and fifth pins respectively on the inside row counting from the “back” (side where the sd card is) of the board. Pin 1 (first inside pin) will go to the Power/Vcc lead, Pin 7 (fourth inside pin) goes to the Data lead, and Pin 9 (fifth inside pin) goes to the GND/ground pin.

That’s it for the physical connection. Now boot it up and see if it’s already working:

cat /sys/bus/w1/devices/28-*/w1_slave

If you see something like the following, it’s working:

XX XX XX XX XX XX XX : crc=51 YES
XX XX XX XX XX XX XX t=23500

The second line t=NNNNN is the temperature in Celsius out to three decimal places so 23500 is 23.500 C.

If you get a “No such file or directory” error then do the following and reboot:

sudo sed -i.bak '$adtoverlay=w1-gpio' /boot/config.txt

EDIT: found a mistake in the ground lead connection instructions

BTW. You can buy some prototyping board (like this) and some through-hole resistor (like this) to practice your soldering, as soldering diodes and switches are pretty much the same technique, and they are super cheap. ;)

I can't speak to if it would work but amazon has them

It depends on the component. Resistors and caps usually either work or not, and even really cheap sets tend to be within rated tolerances. I just buy the cheapest sets of those that have the values I want.

Transistors and ICs will depend on what you're getting. Common and still produced values are cheap and easy to get. Again, just buy whatever's cheap and gets you what you need. Watch out for fakes or seconds when buying out-of-production parts like 308s or 3007s. Best to get those from reputable places (smallbear, Mammoth, etc), because they're expensive and it's easy to get burned. I'd really look at the values you're getting when ordering ICs and possibly transistors in bulk. Those parts are usually really specific to a build and buying a lot of values might leave you with a bunch of unused parts.

The Joe Knows sets are good, if a little expensive. They tend to be well sorted, which is nice, but not something I'm willing to pay more for. Like this set of resistors is going to be just as good and is significantly cheaper than the equivalent Joe Knows set. There's certainly nothing wrong with the Joe Knows stuff though - if it has the values you need at the right price, go for it.

You can also score some great bulk deals on ebay and alibaba, but you'll be stuck waiting for overseas shipping a lot of the time. I'd go Amazon for an initial order and then shop around when you refill.

100-200 Ohms seems about right. But I recommend buying a resistor kit like this instead of the individual values, makes you more flexible for future projects. And it's even cheaper than the 2 single value stips you listed.
