Common Questions

How does the 10% service fee work?
We charge only 10% on top of the material + fitting cost. There are no hidden charges, no platform fees, no markup on components. You pay exactly what the parts cost, plus a small fee for our engineering work.
Do you deliver across India?
Yes! We deliver pan-India. Shipping charges are separate and depend on the weight and destination. For Bangalore-based clients, local pickup is also available.
What do I receive with the completed project?
You receive the fully assembled and tested hardware, complete source code with comments, circuit schematics, a project report (abstract, components list, circuit explanation, code documentation), and 7 days of post-delivery support.
Can you help with project ideas?
Absolutely! If you don't have a specific project in mind, just tell us your subject or semester and we'll suggest projects that match your syllabus and impress evaluators.
How long does delivery take?
Typical turnaround is 5–10 working days depending on component availability and project complexity. We'll give you an exact timeline when we send your quote.
