Terms and Conditions


We do not provide any information to anyone for any reason.

Processing and Shipping Times

All of our kits are custom built per order.  In most cases, all kits with the exception of large kits are shipped with 3-5 business days.  Components and kits in stock typically ship the same or next day.  If there is an additional lead time, as is the case for large custom kits and component packages, we will let you know when you place your order.  This shipping time excludes weekends and holidarys.  Regulator ground service is handled via USPS, UPS, or FEDEX.

Eastern Voltage Research does not guarantee shipping or processing times.  All lead times are estimates only.

Shipping / Handling Charges

Domestic shipping will be shipped via USPS priority, USPS first class, UPS ground, or FEDEX ground.  Eastern Voltage Research reserves the right to choose the appropriate shipping service for the product and destination.  If a customer requires a specific shipping service, they must contact the sales department at the time of order.  Depending on shipping service selected, additional shipping charges may be required.  Shipping and handling charges reflect both actual shipping charges as well as handling, packaging, and transportation time for package drop-off.

Large components or kits may require additional shipping charges.  If you're order requires additional shipping charges, you will be invoiced separately for the balance in shipping.


All partial shipment backorders will be shipped via regular ground service at our expense. 

International Orders and Shipping

All foreign orders are shipping via USPS international priority or international first class unless otherwise noted.  The custom is wholly responsible for all custom duties, brokerage fees, import taxes, VAT, and GST charges that are imposed after the sale.  Also, note that shipping charges estimated for international shipping during the checkout process are estimates only.  If additional shipping charges are required for your particular order, you will be invoiced separately for the balance in shipping costs.  Eastern Voltage Research does not guarantee shipping or processing times.  All lead times are estimates only.

Electronic Kit Limit of Liability

Our range of electronics kits are intended for educational and amateur / hobbyist use only.  They are  not intended for use in commercial or public display applications.  If they are used in such applications, the purchaser assumes all responsibility for ensuring compliance with local laws.  When a product is supplied in kit form and assembly or construction has commenced or the inner component packages have been opened, we are unable to offer any form of refund, replacement, exchange, or free repair.  This is because we cannot guarantee or control the method in which the kit was assembled.  Component packages should be checked against the components list supplied and any shortages or damaged components must be advised to us within 7 days of delivery date to ensure free component replacement.

Kit Reliability

Our range of electronics kits are intended for educational and amateur/hobbyist use only.  The operational reliability of these kits is dependent solely on how the kits are built and how they are operated - both aspects which we at Eastern Voltage Research, have no control over, therefore, we cannot guarantee the reliability or proper operation of these kits in any way, for both short term and long term operation.  Therefore, we do not recommend the use of our kits for long term demonstration purposes, such as exhibits in both commercial, private, and public venues including museums.

Mains Powered Projects

To ensure your safety, please observe these safety measures.  In no way are these complete.  As safety requirements vary, please check with your local authorities in order to comply with local requirements.  If in doubt, seek the help of a qualified person.

Due to their nature and function, some electronics kits and devices require mains power (115VAC or 230VAC) to be connected directly to the kit or assembly.  Extreme care should be taken when assembling and testing these kits.  Mains power must be treated very carefully.  It is strongly recommended that you have previous experience of working with mains powered equipment and/or circuits prior to attempting assembly or operation of these kits or devices.  Mains power can cause serious injury including death and must therefore be treated with extremely caution.  Construction, testing, and use of these kits should only be attempted by competent individuals and/or under the supervision of someone fully experience in this area.

To ensure electrical safety, and also protection from fire or personal injury, make sure your mains powered equipment complies with the safety recommendations below:

  • Use a suitable non-conductive enclosure.  If a metal enclosure is used, be sure that the enclosure is properly grounded to earth ground.
  • Use a power switch for any device that consumes more than 10 watts of power.  A double throw switch should be utilizes for mains operated, transformer-less connections.
  • A fuse or circuit breaker should be utilized in series with the mains switch. 
  • Use a suitable mains power connector and/or a UL compliant three-conductor power cord which is clamped to your enclosure.
  • Use properly insulated and sized wire when making any mains powered connections inside an enclosure.

Eastern Voltage Research accepts no responsibility for injury, loss, or damage of any kind as a result of the purchase, assembly, or use of any of our products.
