Here are some of our most Frequently Asked Questions (FAQs)

Tell me about the battery

The book takes a coincell (CR2032) battery that is secured with a screw. The battery should last 5-10 years. To remove it, you can undo the flap in the back, remove the safety screw, and then slide the battery out with a plastic tool or if you have really grippy fingers.


My book never showed up.

Send me an email, and I'll look up the order status, and will send a replacement if necessary.


What currency are the prices I see on the site?

Prices are in USD, unless you change them at the bottom of the page to be a different currency.


I received my book, but it's not working as expected.

If you can't get the AND page to light up. Try pressing both buttons at the same time.

If two of the internal pages are acting the same, then the most likely cause is that one of the holes didn't get punched out all the way. In which case you should be able to just punch it out with a pencil or something.

Otherwise, reach out to me via email or through the contact-us page and I'll get you squared away with a replacement.


Why can I only buy 1, 3, or 5 copies?

It's all a marketing gimmick to try to get people to buy more. I tested this, and if I just have a regular quantity selector, then the Average Order Value (AOV) is about $5 less than if I have 1, 3, 5 options. If you really just want two copies (or four), then you can checkout with one (or three), and after checkout there is an option to add another copy to your order with a discount.


Do you ship to <my country>? How long does it take?

I am partnered with a fulfillment company in the US, UK, Netherlands, and China.

Orders in the US take a couple days to ship and go out via Media Mail, which is about 6-8 business days. If need expedited shipping, let me know and we can try to figure something out.

Orders in the UK and Europe take a few days to fulfill, and then can take anywhere from 5-20 days to arrive.

Orders anywhere else in the world ship from China, and can take up to a week to fulfill, and another 10-50 days to arrive (usually it's close to 2 weeks, but it's not terribly rare that it takes two months). Also, if you're not in the US or Europe, please put a phone number on your order, or else I'm going to have to email you to get it before the order can ship out.

Tracking numbers will be updated when your order has shipped. If you don't have a tracking number after 7 business please email me, chase at hackyengineering or chase at computerengineeringforbabies.


I am not in love with my order, can it be returned? What if there is an issue?

Yeah, just send me an email and we can arrange a return.


Can I cancel my order?

Of course, just send me an email and I will cancel the order.


I have entered an incorrect address what do I do now?

If you're fast, then you can edit the shipping address by clicking the Edit Shipping Address button on the order confirmation. If you're slow, then you have to email me, and hopefully we can catch it before it gets shipped out.


I want to put this in my store. Do you wholesale?

That would be incredible. Yes. Please reach out to me, and I can give you wholesale pricing.


I have a question that wasn't answered, how do I reach you?

Please send me an email through the contact-us page, or to chase at hackyengineering or chase at computerengineeringforbabies, and I'll take care of you.

I get quite a few emails every day, so please be patient with me. It sometimes takes me a day to respond, and often I ignore emails over the weekend.
