We are looking for a practical freelance Electrical Engineer, Electrical Technician, Electronics Technician, or experienced low-voltage technician for one day of hands-on bench testing support.
Date: Tuesday 16th June
Location: Tamworth, Staffordshire
Duration: 1 day
Type: Freelance / short-term contract
The project involves interfacing with a Japanese gacha / capsule toy mechanism and confirming the safest and most reliable way to trigger or simulate its coin input/output behaviour using low-voltage control hardware.
This is a hands-on role suited to someone comfortable with basic electrical diagnostics, low-voltage DC circuits, relay modules, Arduino / Phidgets-style control hardware, and safe bench testing.
Experience with vending machines, arcade machines, amusement machines, kiosks, photo booths, interactive exhibits, or similar mechanisms would be especially useful.
What we need help with
We need someone to attend our workshop in Tamworth and help us:
- Inspect and understand the wiring of a gacha / capsule toy mechanism
- Identify the coin acceptor output / signal line
- Confirm whether the coin signal can be safely simulated
- Bench test whether we can pulse the signal line directly or need to wire a relay in parallel with the coin acceptor output
- Help test relay-based triggering using either Phidgets hardware or an Arduino-based fallback
- Use a multimeter to confirm voltages, continuity, polarity and signal behaviour
- Advise on safe wiring, fusing, connectors and strain relief
- Help document the final working connection method clearly enough for our team to reproduce on-site
- Flag any risks before we commit to a final control approach
This is not a full electrical installation role. It is primarily a low-voltage bench testing, control interface and fault-finding task.
Useful experience
The ideal person will have practical experience with some or all of the following:
- Low-voltage DC circuits
- Relay modules / solid-state relays
- Opto-isolated relay boards
- Arduino, Phidgets, Raspberry Pi, PLCs or similar control hardware
- Coin acceptors, vending mechanisms, arcade machines, amusement machines or kiosks
- Bench testing and electrical fault finding
- Reading basic wiring and connector layouts
- Safe temporary test wiring
- Multimeter use, including continuity and voltage checks
- Simple input/output triggering and pulse signals
What we have available
We either have or are ordering the following test equipment and parts:
- Phidgets VINT Hub and relay modules
- Arduino boards as fallback control hardware
- 5V opto-isolated Arduino relay modules
- 12V DC power supply
- Inline fuse holder and low-current fuses
- WAGO connectors
- Crocodile clip test leads
- Stranded hook-up wire
- Ferrules and crimp tool
- Heatshrink
- Digital multimeter
- Basic hand tools
You do not necessarily need to supply parts, but please mention if you have additional test equipment or preferred tools.
Please apply with
- A short summary of relevant experience
- Examples of similar low-voltage control, vending, arcade, kiosk, or machine-interface work
- Confirmation that you are available on Tuesday 16th June
- Your day rate
- Your location and whether you can attend in person in Tamworth, Staffordshire
Important
We are looking for someone practical, methodical and safety-conscious.
The outcome we need is a clear, tested, reliable wiring/control method that our team can use confidently without wasting time on trial and error.
Pay: £350.00-£500.00 per day
Work Location: In person
