Every "Soldering Kit" from the Evil Mad Scientist includes all parts and components necessary to assemble the product, along with clear and detailed instructions. (Most kits include printed instructions, but we are slowly moving towards electronic documentation.)

Basic electronic soldering skill is presumed, but no further knowledge of electronics is required or expected. Our goal is that you can have fun building our kits whether or not you happen to know Ohm's law, the resistor color code, or how to read a schematic diagram.

Tools
You will need three basic items to build our kits: A soldering iron, solder, and small flush clippers--more about these below. For some of our kits (like Meggy Jr RGB) it is also necessary to have a set of small pliers (e.g., needlenose).

Iron 1. Soldering iron. You need a basic soldering iron that was designed for electronics assembly, with a reasonably fine point tip. We recommend one of this design-- a "pencil shape" soldering iron (not gun!) with a base that holds the iron and a wet sponge. This particular iron is a medium-high end workhorse from Weller; you do not need quite one this fancy.

On the other hand, the iron that you use does make a big difference in how long it will take you to build a kit. (Seriously. If you use one that is old and broken, or if you go with an ultra-low-end $10 iron, please expect our kits to take you at least twice as long to assemble.) Our recommendation for a low-cost iron: WLC100 by Weller, about $40.


Solder 2. Solder. Fine solder meant for use with electronics. We recommend rosin-core solder, 0.020" in diameter (or within a factor of two of that). Either lead-based or newer lead-free solder will work well with our kits.


Clippers 3. Small flush clippers. Also known as angle clippers. Small, hand-held type that can easily cut the leads of wires and LEDs. You'll use these a lot, so comfort counts. Shown here, one of our favorites-- Sears Craftsman brand.


Some other tools that could be helpful if you happen have them and you know how (and when) to use them: resistor lead bending tool, wire strippers, desoldering braid or pump, multimeter, oscilloscope.

If you're learning to solder, or want to brush up your skills, this classic video is clear and excellent. Another useful resource is the Soldering is easy comic book, which is available in many translations.

Shipping and International Orders 

Shipping
We offer a choice of shipping by USPS First Class mail, USPS Priority Mail, USPS Priority Mail Express as well as UPS options depending on destination. (We do not have Saturday service for UPS as an option.) We charge actual postage rates for shipment, domestic or international, with no added handling fees. For orders to US addresses, we also offer free shipping when your order total is $75 or more. Orders with free shipping selected may be delivered via UPS, USPS, or other carriers at our discretion.

To find shipping options and actual costs for your order, please add the items to your shopping cart. Then, in the cart, enter the destination Country, Postal Code and City, State or Province as needed. You do not need to enter any personal or payment information to view actual postage costs. Particularly heavy orders-- above 60 pounds-- may not be suitable for USPS shipping in a single box; please contact us if our cart is unable to automatically provide pricing for you.

If you would like us to ship an order via FedEX, UPS, or DHL on your own account, please select "Pick up at our shop..." as your shipping option at checkout time. Then, contact us with your order number and shipping account information.

We make every effort to keep products in stock and to ship products quickly; most orders for in-stock items ship by the next business day. While many orders do ship on the day ordered, we do not guarantee same day shipment.

We ship all orders complete: if there are one or more backordered items in your order, your order will not normally ship until everything is ready. If you need some items sooner, please place a separate order.

We may not be able to ship to hotels, some mail forwarders and/or PO Boxes depending on location or if there are known issues with the location.

International Orders 
We ship to most countries. USPS First Class mail delivery time varies depending on destination. USPS International Priority Mail takes 6-10 days to most destinations worldwide. Shipping by USPS Priority Mail Express or UPS is strongly recommended for all international orders. It is faster, more reliable, and provides tracking information that First Class and Priority Mail do not. For all orders with a total value of $2500 or more, shipping via UPS is required (USPS will not ship parcels valued at more than $2500).

USPS First Class mail packages and USPS Priority mail flat rate envelopes do not have an invoice affixed to the outside of the package. USPS Priority Mail Express and UPS packages are shipped with a copy of the invoice enclosed with all required shipping documents. If an electronic copy of an invoice is required, please contact us.

USPS First Class mail and Priority mail do not provide tracking services for international orders and are not insured. If a First Class international or Priority mail international package is lost or damaged in transit, that loss or damage is the responsibility of the buyer. (And for that reason, we do again strongly recommend Priority Mail Express international or UPS.)

Please note: Actual value and contents will be declared on customs forms. We can not and will not mark an order as "gift," "sample," or falsify the value. You may have duties, taxes and/or custom fees charged upon delivery. These fees vary from country to country. You are responsible for paying these fees. So, if your country charges import taxes or fees, please be prepared to pay them. There is no way for us (Evil Mad Science LLC) to calculate fees like these for you; please contact your local authorities if you have concerns about taxes and fees associated with importing products. If you refuse to pay them upon delivery, your package will be returned to us. Upon receipt, we will refund your product (minus shipping fees for both ways).

Customs processing frequently requires an invoice, and we include a copy of the invoice in each international shipment. However, please keep a printed copy of your e-mailed order confirmation in case you need to send it to your customs office or shipping carrier for processing.

Also note that unexpected delays can sometimes occur in customs processing, and that this is also not within our control.

Local Pickup 
Our normal hours for will-call pickup are Noon to 6 pm Monday through Friday. We are occasionally available outside of those hours by appointment; please use our contact form to inquire.

If you'd like to pick up your order at our store in Sunnyvale, California, please select "Pick up at our shop in Sunnyvale, CA" as your shipping method. We'll e-mail you when your order is ready for pickup, usually by the next business day. There's no shipping or handling fee, but we do collect sales tax on orders for local pickup. Our location is 1285 Forgewood Ave, Sunnyvale CA 94089, and we are closed on most mail holidays.


Customer Service 

Making Changes to Existing Orders 
If you need to add additional items to your order, the easiest way to do so is to (1) let us know that you would like to do so-- so that we catch your order before it ships --and (2) place a separate order for the additional items. We can then combine shipping costs and issue a refund for any excess postage paid.
If you would prefer it, we can instead send a PayPal invoice for just the additional items and any incremental shipping cost incurred.

Canceling Orders 
Any order for stock items can be canceled for a full refund, right up until it ships. Please contact customer service with your order number if you would like to do so.

Returns 
Provided that they are still in original condition, we can accept returns on most stock items. If you decide that a product is simply "not for you," please contact us for a return authorization and address. When we receive your shipment, we will issue a full refund less shipping costs. Returned orders need to be received within 45 days of the original purchase or a restocking fee may apply. A restocking fee may apply for items returned not in original condition. We do not accept returns of soldering kits which have been partially or fully assembled.

Please do not return products to us without contacting us and receiving a return authorization first. Return shipping cost is paid for by the customer except for authorized returns of damaged or defective products.

Warranty 
Please contact us right away if you have any problems with your order. We will do everything in our power to correct the situation and make it right, as quickly as possible.

Undeliverable packages 
We do our best to make sure that our products really get to you. However, if all else fails and your package is returned to us as "undeliverable," it is our policy to refund your order less shipping costs.


Payment and sales taxes 

Payments
You can place your order directly from our secure payment form using PayPal, BitCoin, your Amazon.com account, or Visa, MasterCard, American Express, or Discover cards.

By special arrangement we can also accept payments through domestic or international wire transfers, purchase orders, or a paper check or money order. Please contact us if you would like to set up an order using one of these alternate means.

There is no minimum order amount; if you're willing to pay for freight, we'll be happy to send you any size order.

We also accept payments in cash and by credit card in person at our Sunnyvale store. You are welcome to stop by if you would like to place an order, but please note that not all of our products are out on display for immediate purchase, and we do encourage you to take advantage of the "local pickup" option at our web store.

Cardholder Data Security Policies:?
In order to minimize the risk of security incidents, we fully outsource all payment processing to FoxyCart.com. FoxyCart is PCI DSS (Payment Card Industry Data Security Standard) Compliant as a Level 1 Service Provider, and is listed on both Visa and MasterCard's global registries. Anytime you submit payment information via our website, you are submitting through FoxyCart's secure infrastructure. If you opt to save your payment information during checkout, that information is stored at FoxyCart. Neither or staff nor our computers have access to your payment details except for the last 4 digits, the card type, and the expiration date.

Sales Tax and California Orders 
Sales tax will be collected on orders shipped to California addresses unless prior arrangements are made. Sales tax is not collected to orders shipping outside of California.
