Hark Tech is a one-person workshop in Basingstoke. I run it, I do the repairs, I bench-test the kit, and I post it back to you. No call-centre, no outsourced “fulfilment”, no being passed between technicians.
Many years of self-taught hands-on hardware work — consumer electronics, 3D printers, embedded Linux, low-level firmware, and component-level board repair. The kind of work most shops won’t touch because it doesn’t scale.
Recent and ongoing work — both customer jobs and the infrastructure that keeps this place running.
Built a custom slicer-aware parser for the print-order tool so customers get firm prices on Bambu Studio / OrcaSlicer sliced files in seconds — most UK competitors still bounce these to manual quote forms.

Applied five input-shaper math fixes and bed-level tuning to the workshop’s Creality K2. Patches documented as public help articles so other K2 owners can apply them.

Decommissioned a local business’s on-prem stack — switches, server hardware, IP phone system, multi-camera Blue Iris setup. Migrated active services to cloud and handed off the SonicWall firewall cleanly.

Hark Tech runs its own Proxmox cluster: Pi-hole HA pair, PBS backups, Cloudflare tunnels, fail2ban-defended nginx. Same architecture I deploy for SMB clients.

Currently working through PS5 HDMI ports, Xbox Series X disc drives, and Switch Joy-Con drifts alongside the print queue. Recent work has included board-level console repairs and small-batch 3D prints.

Need an engineer for a one-off project rather than a managed-services contract? Get in touch.
If it can’t be fixed, I’ll tell you. If it can, I’ll do it properly. Either way, the same person who quotes your repair is the person on the bench — and on the email replying to you.

The bench has seen a lot of different kit over the years. These are the areas where the experience runs deepest.
Klipper configuration, pressure advance and input shaping, mechanical rebuilds, multi-material systems, and rescuing printers stuck on poor or unsupported vendor firmware.
Bricked devices, bootloader recovery, reverse engineering proprietary firmware, binary patching, and porting open firmware onto hardware the manufacturer locked down.
Surface-mount rework, trace repair, micro-soldering, and fault-finding down to the individual component — not whole-board swaps at the customer’s expense.
Laptops, desktops, gaming consoles, monitors and audio gear — with honest advice when a repair genuinely isn’t worth doing. No padding the bill.
A mail-in service only works if customers genuinely trust the person on the other end of the post. Here's the promise we make to every one of them.
I work from a private residential workshop, so the full postal address is shared by email once your job is booked — you’ll always have it before you ship anything.
If it can't be fixed, or if the repair cost exceeds the value of the item, we'll tell you plainly. No-fix, no-fee — you don't pay for work we couldn't do.
You get a written quote before any work starts, and we never extend the scope without your approval. If we find something extra inside, we stop and ask.
We access only what's strictly needed to test the repair. Personal files are never opened, and data-sensitive devices can be worked on without booting the OS when you ask.
Every repair carries a 90-day warranty. If the same fault comes back in that window, we put it right at no further charge.
Most repairs are back in the post within 5–10 working days of arriving at the workshop. Complex jobs take longer — but we'll give you a realistic estimate up front and keep you updated.
Your item isn't passed between technicians. The same person answers your email, does the work, tests it and re-packs it for return — so the context is never lost.
Send us a few photos and a description — we'll reply within one business day with a no-obligation quote.
Buyer feedback from my eBay seller account (hark-tech31), where I refurbish and resell electronics. These comments are from buyers, not repair customers — but they are a public, third-party record of how I communicate, pack and ship. Repair-customer reviews are building up on Google — leave one here.
