[Dinkum]Complete strategy guide for Franklin's inventions | Thorough explanation of all recipes, material list, early priority rankings, and durability management techniques[Latest Switch/PC version in 2025]

Dinkum is an open world survival craft game set in the Australian outback. The slow life of building a town from a deserted island is appealing, but the downside is that the early stages of moving and leveling the land are tedious and time-consuming. That's where the inventor, Franklin, appears. The inventions he creates in his lab dramatically improve the experience of gaming. In particular, tools such as motorcycles and compressors can dramatically improve the quality of life on the island.

In this article, we will comprehensively explain everything from Franklin's migration conditions, recipes for all inventions, priority rankings for early, middle, and late stages, techniques to improve the efficiency of collecting materials, and tips for managing durability. We will accelerate your island development as quickly as possible, including player experiences.

1. Conditions for inviting Franklin to the island and the process of building the research institute

Franklin randomly appears on visitor sites after John settles in. To encourage migration, the following conditions must be met:

• Friendship level: 0.75 or higher (raised through daily conversations and gifts. Favorite food is Cooked Giant Drumstick)
• Transaction amount: 190,000 dinks or more (counted by shopping at the research institute and selling glowing discs)
• Timing: The frequency of visits will increase from autumn after John settles in.

If you clear the conditions, you will receive a “Crafting Lab Deed” (building permit for the laboratory). Ask Fletch to build it (4×4 size, construction cost added to debt). It will take 2 days to complete. Business hours are from 8 a.m. to 4 p.m., closed on Saturdays and Sundays.

Tips for efficiency:

• Collect glowing discs with priority and sell them to Franklin (1 disc increases transaction amount + opens recipes)
• Pay off the debt before building the lab (sold at John's store). Required for new Deed application

This will unlock Franklin's invention.

2. Complete list of Franklin inventions & recipe/material list

Materials are brought in to the research institute, produced on commission, and delivered by post the next morning. Recipes will be released sequentially depending on the number of glowing discs sold and Belconium ore delivered. All recipes are summarized in a table below (Dink is a creation fee).

Basics of obtaining materials:

• Glowing Disc: Dig the Deep Mine with a metal detector. More than 10 pieces per day possible
• Old Gears/Springs/Device: Obtained from trash bins and deep mine boxes.
• Hot Cylinder: Obtained from an enemy drop or blast furnace on the 2nd floor of Deep Mine.
• Opal: Obtain in large quantities through cave mining and night events.

3. Ranking of first priority inventions (top 5 lifestyle revolutions)

In the early stages, give top priority to movement, ground leveling, and durability management. This ranking is based on the ease of obtaining ingredients and immediate effectiveness.

1st place: Charging station (essential infrastructure)

This is a power recovery device for electric tools. If you're going to use a chainsaw or compressor, you'll definitely want to make it first. To use it, just place your tools down and it will fully charge in 600 seconds (even faster if you place it near a solar panel).

Creation flow:

1. Unlocked by selling 10 glowing discs
2. Collect copper/iron bars and wire
3. I ordered it and received it the next morning.

Player's voice: “I would cry if the power went out and it broke. This is a must-have at home.”

2nd place: Motorcycle (ground transportation revolution)

You can move at more than 3 times your walking speed. It has a small turning radius and can jump over steps. It is also safe to travel at night. The trick is to climb the hill with the accelerator fully open and use the brakes to prevent sharp turns.

3rd place: Compressor (earth leveling sacred treasure)

It crushes the ground and flattens it instantly. Terraform large areas in minutes. Continuous jetting can even collapse cliffs.

Player comments: “Leveling the land without a compactor is torture. Level the area around the house first.”

4th place: Jet ski (water high speed)

Travel at high speed through oceans and rivers. Access to fishing points will be dramatically improved. Be careful of shallow water, and if you ride a wave it will accelerate even more.

5th place: Dirt printer (soil mounding)

You can freely generate soil. Indispensable for hill construction and bridge construction. The bottleneck is 5 opals, but they are easy to collect in the cave.

Recommended for mid-game and beyond: Chainsaw (wood cutting), Jackhammer (ore mining), Ute (carrying luggage)

Recommended second half: Helicopter (excellent hovering performance), airplane (mass transportation)

4. Detailed usage of each invention & troubleshooting

Compactor & dirt printer grading combo

It is flattened with a compressor and then raised with a dirt printer. A large city block will be completed in one day. The durability is 600 seconds, so be careful not to forget to charge it.

Complete manual for power tool durability management

• You can also use a repair stand to restore normal durability (1 repair kit per day).

Estimated charging time:

tool	time
chainsaw	600 seconds
compressor	600 seconds
jackhammer	600 seconds

• Measures to prevent breakage: Install solar panels, use food buffs

5. Material resurgence point & efficiency loop

• Iron/Copper/Stone: Go around the east side of Deep Mine 1st floor at high speed with a jackhammer.
• Old parts: Obtained from townspeople's trash cans and deep mine boxes.
• Glowing Disc: Dig mines at night with Metal Detector Lv2. More than 20 photos per hour is possible.

Efficiency loop: Sell disks → Create inventions → Increase mining efficiency → Further increase disks

6. Tips to learn from player commentary

• “Franklin never came…I kept praying until fall.”
• “It's confusing to operate a motorcycle at first, but once you get used to it, you won't be able to put it down.”
• “I was traumatized by the experience of my chainsaw exploding when it ran out of power. Charging stations are a lifeline.”

7. Summary: Island goes serious with Franklin Investment

Franklin's invention fundamentally changes the way Dinkum is played. Early on, equipping yourself with charging stations, motorcycles, compressors, jet skis, and dirt printers will cut your time by a third. Collect 20 glowing discs to unlock the dirt printer and manage its durability thoroughly. With all the recipes, your island will definitely become the best city in the world.
