Fixed!

I did actually watch all of the YouTube tutorials and found them useful.

You beat me to it eclectic! However, if it makes a difference, my calipers say 61 x 41 mm bare board (plus 2mm if you need to account for the sticking out bit of the download socket). And, by the way, yes these measurements were taken from one of the boards that you kindly gave me some years ago...

I don't think that there was ever a proper datasheet for the AXE201.

Ah, totally different type of SmartBoard from the one you originally linked to. I think it is this one. Those cameras just need to identify if something is in their path and so probably wouldn't be useful for anything apart from sensing. Like the other SmartBoards, they use a USB connection and...

The board you have linked to (SmartBoard 680) has a resistive touch matrix to detect where the screen has been pressed. I don't know about cameras in each corner; I thought it had optical sensors in each of the pen trays to detect which pen has been taken out of its tray. I have a similar...

If you have an electric toothbrush charger and the coil from the base of an old electric toothbrush, that might be enough to start some experimentation. Couple that with a small charge controller board and you might get there. For solar charging, Adafruit make a kit but you can buy the bits...

If you are intending to use a Picaxe, you are best advised to use the Picaxe backpack, either as a complete module or, as Flenser suggests, as an add-on (the AXE132 serial backpack board). However, be aware that the pins on that board are on the opposite side from most budget LCDs so adding the...

SBrick+ not detected OK, back from holiday and I've tried the SBrick+ with S2Bot v8.0 Chrome App and can't get it to detect the SBrick+. For what it's worth, I couldn't get S2Bot 0.7.4 Chrome App to work either. When I run S2Bot (with the BLED dongle inserted), I click "Scan for devices" and...

Adafruit sell some nice 4x14-segment displays with an I2C backpack based on the Holtek HT16K33 driver chip. This thread discussed using the same backpack with a 4x7-segment display and I posted another code snippet for controlling an 8x8 LED matrix. The code snippet below shows how to control...

I was just wondering if/when S2Bot will support the new Sbrick Plus? I know it already supports the SBrick output devices, but Vengit's own software is, to say the least, flaky and S2Bot support for the WeDo 1.0 input devices would be much nicer.

I couldn't find any Picaxe Basic code examples for controlling this display, but this thread described how to control a 4-digit, 7-segment display that uses the same backpack. Building on the information in that thread, I have produced the following code that demonstrates how to turn on/off...

I bought a couple of 8x8 LED matrices that use the same i2c Adafruit backpack with the HT16K33 chip. It took me a while to figure out how to turn on the correct pixels in the matrix as there are a couple of "gotchas" due to the way the LED matrix is wired. 1. After initialising, the starting...

Looking at the data sheet for this sensor, I can't make out from the diagram on p4 of the data sheet which way round are the +ve and -ve connections. I don't want to fry this expensive component so can anybody tell me how to identify the +ve from the -ve? Looking at the photo below, is +ve on...

I was wondering when the new Sbrick Plus will be supported in S2Bot (i.e. sensors). Any news?
