Need Some Shipping Relief

Id love to buy some jumpers from the online store here. I popped em in my cart and started the checkout. Shipping was over $21USD. For a $9 item that weighs nothing. So I cant buy them.

Date Calculation

If you move the joystick slightly in one direction, The arm moves continuously slowly in the direction. If you move the joystick strongly in one direction, The arm moves continuously rapidly in one direction. For my robot I would like...

Omnibot 5402 - Belts

Saw a few posts about Omnibots here, joined the site hoping for some help. Just put a battery in my old Omnibot... has been on a shelf since the late 80s. Turned it on, went to test the tape deck and the motor turns without a tape, but with a tape it doesnt. I suspect a slipping belt issue. Anyone know what belt I need for the deck on this? Thanks
