Where everything I build gets designed, soldered, measured and broken. A home electronics lab built up piece by piece since I started — and still growing.
| Instrument | Model | What I use it for |
|---|---|---|
| Oscilloscope | Hantek DSO2D15 | General debugging, though limited by 8-bit resolution (12 mV noise floor) and 2 channels for multi-axis measurements on power electronics and motor control |
| Bench multimeter | OWON XDM1041 (55,000 counts) | Precise measurements without another handheld cluttering the desk |
| Bench power supply | ZUZIZAO SPPS3010-2KD | High Power, 2CHA, SER/PAR, OVP and OCP, just perfect |
| Bench power supply | Jesverty 30 V / 10 A | Low ripple, precise, and it runs anything I need to test |
| LCR meter | FNIRSI LC1020E | High-precision component characterisation |
| Logic analyser | Alientek DL16 — 250 MHz, 16 ch | Serious digital debugging (I²C, UART, SPI) |
| Logic analyser | 24 MHz, 8 ch | The cheap one that started it all — still handy for quick captures |
The logic analysers earned their place during the I²C stress test on my robotic arm — hunting for NACKs on a 1.3 m bus wrapped around a running stepper.
| Tool | Model | Notes |
|---|---|---|
| Soldering iron | Geeboon TC22 | Hits temperature in ~2 s, dead accurate, cheap tips, hundreds of tip profiles available |
| Hot air station | Toolcraft ZD8908 | SMD rework and desoldering |
| Fume extractor | YIHUA 948 Q I | Because breathing flux fumes all evening is a bad plan |
Creality K1 SE — heavily modified
Fitted with a custom plexiglass enclosure and a temperature control system I designed and built myself:
- ESP32 + LCD + NTC thermistor + MOSFET, powered by a 24 V → 5 V buck converter
- A web interface to monitor chamber temperature and set a target
- Simple hysteresis logic: above target + 1 °C the extraction fan runs at 100 %, down to target − 1 °C
Custom-built printer — based on a Geeetech A10M dual extruder
Rebuilt from the ground up into a large ventilated enclosure (plexiglass + 2020 aluminium extrusion), running Klipper on a Raspberry Pi 3.
Filament dryer — Sunlu
| CPU | Intel i7-4770 |
| RAM | 32 GB DDR3 |
| GPU | RTX 3060 12 GB |
| Storage | 10 TB HDD + 256 GB SSD (OS) |
Runs local LLMs and AI agents on the GPU, alongside Nextcloud, a NAS, Paperless and Pi-hole.
This didn't appear overnight. It started with a couple of red bins, one bench supply and a single monitor — everything else was added one piece at a time, usually because a project needed it.
