I know Scott knows this now, but the adaptor board is more than just that.....it has a TFT driver on it c/w integral uController/SDRam and all the software/hardware necessary to drive a TFT LCD. This means that just two SPI interfaces and a few discrete I/O lines are all that's necessary to drive the TFT, i.e. an Arduino could be used.......or in my case an STM32 BluePill.

What board you mean ? Didn't see any

[@IanScottJohnston]

@@jw200 @3:45 I think Scott was talking about an Arduino adaptor board that drives the large LCD.....I thought initially he was talking about the smaller adaptor board that drives the LCD......but perhaps not...........Anyways, a box from a far, far away place is on it's way to him that will reveal all...🙂

The last mailbag Monday/Sunday for 2024. See you next year 😎.

Can’t wait to see the review I think I’ve seen this on Dave Jones channel they’re awesome tweezers for the price if I did not have the JBC tweezers, I would probably purchase them

I consider any threaded device with a slotted or Philips head a screw but if it has a hex head, I call that a bolt. 🤠

[@IanScottJohnston]

Yup, if you search RS etc that's how it comes up.....including searching for "panhead bolt" which of course lists screws.

I got the Handskit solder tweezers, ( Claytons tweezers ) while they are ok for the occasional smd tweak they have a far bit of lateral slop . keen to see how these go .

[@GregM]

I saw NorthWestRepair review on those tweezers. He seemed to show a voltage leak on the tips when using a USB-C adapter to power them. Put a scope on them with the ground to ground plane of a circuit board and see if the positive probe from the oscilloscope shows any voltage off the legs of the tweezers when they are powered on and in contact with a component on the same motherboard.

I think that result will depend a lot on the USB-C power supply used with the unit, I checked my unit and I was only getting 1.9VAC to earth.

[@IanScottJohnston]

Got same tweezers, mine shows quite a high ACV to earth, and obviously drops instantly to 0 VAC when you earth one of the tips. Suspect it's just capacitive coupling which is common in devices with non-earth referenced heating elements. Could be an issue with sensitive components though despite fact it's a very, very low current. Depending on the DMM you use to measure it you may or may not see the issue, needs a high impedance meter. Yep, very nice tweezers but looks like they do have a wee flaw there......possibly needing a resistor to earth. My JBC iron doesn't though, it has a
