Description

buffer pedal Buffer PCBA tiny buffer circuit to use as part of another circuit or by itself. Simple layout and clean sound with unity gain. Use on boards with many true bypass pedals, or to buffer a longer cable run to prevent signal loss. Includes the circuit board only. The LED positive leg connects to the "LED" pad, and the negative lead connects to power supply ground. The 6k8 resistor may be adjusted to a higher value for a more dim LED, or lower value for a brighter

A tiny buffer circuit to use as part of another circuit or by itself. Simple layout and clean sound with unity gain. Use on boards with many true bypass pedals, or to buffer a longer cable run to prevent signal loss. Includes the circuit board only.

The LED positive leg connects to the "LED" pad, and the negative lead connects to power supply ground. The 6k8 resistor may be adjusted to a higher value for a more dim LED, or lower value for a brighter LED (330 Ohms minimum for 9V). If no LED is required, the 6k8 resistor may be omitted and the "LED" pad requires no connection.

The circuit may be run at 9V or up to 18V with the parts listed below.

Works and is engineered exactly as I expected it to be. Unlike SO MANY OTHERS.
Color: 2-Speed Rechargeable Set with Charging Base
I've ordered about 4 different automatic shakers from different brands. They all have different problems, motor not strong enough, charging cable on the front of the charging base (in the way on a counter), hard to open refil covers, small containers not holding enough salt/pepper. FINALLY this one checks all the marks I've been looking for. Its weighty too since its made of stainless. Large refil container, easy to remove just a twist. Grind selector is a twist at th e base with a clear arrow showing size. Large press button at top so you can hold it in any rotation in your hand and not have to look for the button/switch to turn it on. No cover that needs to be flipped open and then closed to put back into the base. Contacts for charge are on the back side and not at the bottom where salt can corrode the contacts. The list can go on but you get the idea. Just buy this one and be done with it!

Nice product
Color: 2-Speed Rechargeable Set with Charging Base
Edit: Customer service actually did offer to replace it. Received the new set and it works fine. Nice set. Only gripe is I think that the motor could be a little stronger. Sounds like it’s struggling at times. Received a defective item reached out to customer support for Circle joy and they’re basically saying that it’s user error and not a defect in their product, even though I explained to them that the other one works fine. When adjusting the coarseness on one of the grinders, the grinder ends up loosening up, which ends up with you spilling the pepper corns everywhere. It’s a nice set if it worked right but for $40 I expect her device to be a little more polished.

great for my bad hands, hygenic, easy to use.
Color: 2-Speed Rechargeable Set with Charging Base
so far so good. I cook a couple times a day. I also have bad RA in my joints. this product has really helped already. from the clean size adjustment to the ease of charging. Like i have owned it for years is how easy this product has entered my kitchen routine. strong product and hygenic because you adjust the grind from twisting the body, not messing inside the grinder.
