DIY Soldering Kits · Beginner to Intermediate · All Components Included · Ships Across Europe
You bought the soldering iron. Maybe you've done a bit of YouTube watching. Now you want a project that actually goes somewhere, something that works when you're done, looks good on a shelf, and teaches you something real along the way.
These five kits from Slotman Customs are exactly that. Each one ships with every component you need. No ordering extras, no chasing datasheets. Just solder, build, and end up with something genuinely cool.
Whether you're just starting out or already comfortable with a hot iron, there's a kit here for you.

1. Roulette Kit
The one everyone wants to spin.
Build a fully working electronic roulette wheel from scratch. Real LEDs, realistic spinning action, and a finished build you'll actually want to show off. This is the kit that gets people asking questions at parties — and it's the most accessible build in the range.
Everything is in the box. Detailed step-by-step instructions mean you spend time building, not troubleshooting.
€16.75
2. HE056 Ceramic LED Clock Kit
A clock you built yourself. That actually sits on your desk.
Solder together a premium ceramic LED clock that looks as good as it works. Bright, clear LED display. Modern design that fits anywhere — a desk, a shelf, a workbench. Assembly takes 1 to 2 hours, making it an ideal first project with a clear finish line.
CE certified, 182×28×82mm, powered via USB-A (not included). All assembly components and instructions are in the box.
€19.99
3. LED Matrix Display Soldering Kit
88 components. 202 solder joints. One serious skill upgrade.
This is the kit you reach for when you want to level up. The 8×8 LED matrix teaches SMD (surface-mount) soldering — the technique used in real consumer electronics production. Once assembled, it cycles through light patterns automatically: full flash, horizontal scan, countdown display, and more.
The JP1 interface lets you hook it up to your own microcontroller and display custom content. The most affordable kit in the range, and arguably the most educational.
€4.75
4. Photo-Electric Piano Kit
Play music with light beams. No strings. No keys. Just your hand.
This photo-electric piano uses seven light beams instead of traditional strings. Block a beam with your hand, and the microcontroller triggers a musical note while the matching LED lights up. All seven beams play different pitches — enough to play simple melodies.
It uses photo-resistors, a pre-programmed STC microcontroller, and a passive buzzer covering the full 20Hz–20kHz range. This is the kit that makes people stop and ask "how does that work?" — and you'll actually be able to answer.
€23.25
5. Digital Scale Soldering Kit
Build it. Weigh things with it. Actually use it.
Not every kit sits in a drawer after you build it. This one earns a spot on your workbench. The finished scale handles up to 1kg using an HX711 24-bit load cell amplifier — professional-grade precision in a DIY package. A 51-series microcontroller drives a clear digital segment display that shows your readings in real time.
This kit is ideal if you want to understand how commercial scales actually work, not just from the outside.
€22.53
Choosing by skill level
If you've never soldered before, start with the Roulette Kit. It uses through-hole components only, the instructions are clear, and the payoff — a working light-up roulette wheel — is immediate and satisfying.
The Ceramic LED Clock is a natural second step. Still through-hole, slightly more precise work around the display and power circuit, and the result is something you'll use daily.
The LED Matrix Display kit is technically labelled beginner to intermediate, but it's worth a section of its own: this is where you learn SMD soldering. Surface-mount components are smaller and require a steadier hand, but the kit is designed with training in mind. At €4.75, it's also a low-risk way to try a new technique.
The Piano Kit and Scale Kit are both solid intermediate builds. The Piano is more theatrical — it's the one you demonstrate. The Scale is more practical — it's the one you keep on the bench. Both use microcontrollers and sensors that give you a real feel for how embedded electronics work.
Choosing by what you want to end up with
- Conversation piece for parties → Roulette Kit
- Object you'll use every day → Ceramic Clock Kit or Scale Kit
- Skill you want to develop → LED Matrix Kit (SMD) or Piano Kit (microcontrollers + sensors)
- Gift for a teenager or student → Piano Kit or Roulette Kit
