    Just ordered the track set for my four wheel rover, https://shop.pimoroni.com/products/p...t=933151014922 These will fit the shafts on the motors I already have. This rover is the one that's been fighting me almost all the way. I'm going to use 4 motors instead of two motors and two idlers. I'm going to try anyway. If that doesn't work I'll just pull two motors out, one on each side, and put the idler shafts in. Added a few other odds and ends to the order. Another Pi Zero W, and official case. I want to have another go at the bird camera setup and need a Zero with no header.
    • 1x Pico HAT Hacker for £1.67 each
    • 1x LED SHIM for £6.25 each
    • 1x Raspberry Pi Zero W for £7.63 each
    • 1x Pirate-brand Plastic Loot Box for £2.08 each
    • 1x DC Barrel Power Jack/Connector for £1.25 each
    • 2x Official Raspberry Pi Universal Power Supply for £6.67 each
    • 4x Male 40-pin 2x20 HAT Header - Male 40-pin Header for £0.83 each
    • 2x Male 40-pin 2x20 HAT Header - Male Right-Angle 40-pin Header for £0.83 each
    • 1x Mini Black HAT Hack3r - PCB only for £3.33 each
    • 2x M2.5 Standoffs for Pi HATs - Black Plated - Pack of 2 for £1.67 each
    • 2x Premium Pi standoff selection for £3.75 each
    • 1x Pololu Track Set - 30T for £10.00 each

    The electronics for this rover is going inside that loot box. I'm ditching the modified aluminum chassis I have now and will mount the motors to the bottom of the loot box. I need to adjust the wheel base for the track set anyway. I'm going to do up a new mini black hac3r board too. The original has those Pimoroni stacking headers on it that I don't like. The male pins are a bit thin and bend too easy for my liking. And I don't need the female header on the bottom. Seemed like a good idea at the time. I'll just use normal Male headers. That will let me get it nice a low in the loot box. I have a bunch of those white Adafruit Proto Boards, been getting one free with each order. I'll put those in the loot box and bolt the motors to them. That will get me some strength and rigidity. I think I'll wire the motor power terminals to them too. I'll post pictures as I go.

    I also bought one of those LED Shims, https://shop.pimoroni.com/products/led-shim
    My plan is to replace the four 10mm (Red, Yellow, Green, Blue) LEDs in my portable weather clock with it. I'll mount it vertically to show temperature or pressure. Probably temperature. A colored scale with a white marker. Just a quick glance indicator. It's 28 RGB LED's. I'll solder it to the Pico Hat Hacker, and mount that to the back of my diffuser. The shim has no mounting holes, but the Pico hat has. It will get the shim nice and close to the diffuser too. It used i2c so I'll use female to female jumpers to connect it to one of the Proto Hats. Same way I connected all the other i2c sensor breakout boards. I'll just put a small 4 or 5 pin right angle header on the Pico hat. The coding in python is (again) going to be the hard part.

    I had the x86 ISO download stall at 94%. I finally just canceled it and started it over again. It just picked up where it had stalled instead of starting over. It must have saved the partial download even though I canceled it. Their download servers must be getting hammered. I would have went with the bit torrent option but I don't have a client installed at the moment. Anyway, I have all 3 now. Haven't done anything with them yet. Still mulling over if I want to do any reinstalls / reimage or not. If I do it will be the x86 one on my spare desktop. Just to have a look see at the new menu's etc. Most of my other setups are working fine, or are a work in progress I'd rather not start over. Might also do my bread board rig, its my only 3B+. Would just have to redo my RTC setup again. That one I can just take out on my deck to play with. I see blue skies so it looks like it might be a nice day after all.

    Im going to try the ,update, upgrade on the pizero-w i had running in my latop setup i was making last week when i get home tomorrow evening ..to check the browser speed The Chromium browser is now at version 65

    and also do the following.
    install the new PDF viewer (and remove the old one):
    sudo apt-get install qpdfview
    sudo apt-get purge xpdf

    To install the new Recommended Software program:
    sudo apt-get install rp-prefapps

    then i'll try this , install the setup wizard (which really isn’t necessary on an existing image, but just in case you are curious…):
    sudo apt-get install piwiz

    Just doing the above on my Pi 3B+. Just turned it on out on my deck. Decided not to start over from scratch.
