User questions & answers

Question:	Can i buy extra grit without the rocks. we have many rocks from "mining" gemstones that i would love to polish. what do you recommend
Answer:	Hello, currently, our GUI app can only run on Linux and Windows platforms. We are developing an Android app, it will be released in two months. THX!
Question:	What pound tumbler is this product
Answer:	Hello, RaspTank does not include the Raspberry Pi board, you need to buy the Raspberry Pi yourself. You can connect the keyboard and mouse directly to the Raspberry Pi to program. You can also use the PC to connect to the Raspberry Pi to program via ssh.
Question:	What the difference between this and the starter kit
Answer:	YES.
Question:	What is the power consumption of this unit over a week of continuous use? (in usa on 110v). thank you
Answer:	Yes, it can turn left and right. The calibration wasn't exactly straight forward but after a few tries was able to find and acceptable 'straight' setting and it drives okay. Speed is normal RC car speed, slightly faster than human walking so maybe 5-10 mph tops. The lag between the app and the car is a bit of a problem and at higher speeds you end up running into stuff a lot.

User questions & answers

Question:	Can't open
Answer:	Don't put more than a pound of rocks in it or the motor won't be able to turn. Does it turn without the tumbler? Then that is likely the problem. Otherwise contact the manufacturer. That may not be easy as it's Chinese I think.
Question:	How many pounds/ounces of rocks can you put into the barrel with grit for tumbling
Answer:	I don’t think there is a warranty for it. However, if it’s defective call the company. They seem to be really good at doing the right thing
Question:	Where can I buy more grit
Answer:	The power supply will work with 100-240v. It has a US plug.
Question:	Can this be used to tumble glass to make sea glass
Answer:	grit is available on the Amazon site....I bought extra when I bought the tumbler :)

User questions & answers

Question:	Mine didn't come with an instruction booklet. Where can i find one online or request one
Answer:	Hello, The Hobby Rock Tumbler can hold 1lb of rocks. Comparably, the Professional Series Tumbler can hold 2lbs. Thank you for your inquiry, National Geographic Toys Customer Support
Question:	I get an error code everytime I try and run it doesn't anyone know why? I hardly have anything in it
Answer:	There are two main differences:The Hobby Rock Tumbler has a rubber tumbling barrel with a stainless steel cap, which reduces noise and is more durable. The Starter Kit Rock Tumbler has a plastic barrel. The Hobby Rock Tumbler also has a keypad for setting the number of days you would like it to tumble, where as the Starter Kit Rock Tumbler's setting options are on/off. Thank you for your inquiry.
Question:	what is the warranty for and how long is it
Answer:	This takes .3 Amps, so (watts = amps x volts) OR watts = .3 x 110 which equals33 watts. Now for one week would equal 33 watts x 7 days x 24 hours =5544 watts or 5.54 kilowatts for one week.At $.16 per kilowatt it comes to $.89 per week.
Question:	Can you confirm the voltage rating of the power cord? only 110v or up to 240v? thank you
Answer:	Hello, you should run code/server/sever.py on the Raspberry Pi and code/Client/RaspTank.py on the PC(Windows or Ubuntu Linux). Please refer to these two videos: https://www.adeept.com/video/detail-70.html https://www.adeept.com/video/detail-53.html If you have other questions, please contact Adeept support Team by Email.
