I don’t normally support things on Kickstarter as I’m scared that the project will fail and I’ll loose my money ( I have seen it happen,) however I friend on mine told me about the project and for the first time I jumped on board.

The project in question is the Robotics Construction Kit by Geeekclub https://www.kickstarter.com/projects/geeekclub/geeek-club-diy-robotics-kit?ref=user_menu

The project was successfully funded, but there was an issue with the email (i had the wrong email in my kickstarter account.) With the help of my friend acting as middleman we managed to get the email sorted out and now I am 1220th inline to get my kit.

I didn’t really need all the tools but, for once I had some spare pennies and decided to invest in the kit.

Feeling good about my investment (and board because this is written in the middle of the 2020 Covid19 Global Pandemic) I started to explore kickstarter to see what else is there.

Currently I have invested in the M5Stack range of products which includes 1515 aluminium extrusion https://m5stack.com/collections/m5-aluminium and the Totem Makers system of plastic extrusion https://totemmaker.net which are interesting and cross compatible due to the use of M3 Fittings used by both.

Going back onto the Kickstarter site I went looking for other project of interest. While searching I came across another successfully funded project called NanoBeam. https://www.nanobeam.us NanoBeam is a system of tiny aluminium extrusion items with a profile of only 5mm X 5mm

Unlike Totemmaker and M5Stack, the parts are too small to use M3 fittings and instead use M1 size fittings. I can’t wait until I have some money to invest in a kit to see what I can do with the kit.

What else can I find?

Next is the Makeblock Platform

https://www.kickstarter.com/projects/1397854503/makeblock-next-generation-of-construct-platform/description It is another construction system but I cant tell if the kickstarter was successful or not.

Anything Else?

Next up is MOSS https://www.modrobotics.com/moss/
MOSS is a magnetic screw less construction kit but looking at the prices’ is out of my budget range.

Multiplo https://www.modrobotics.com/moss/ Another Robot construction system

I am sure there are loads of others worth mentioning but this post has already taken me nearly an hour to write and my own products that need finishing.

If you found this post useful, please drop me a message to say thanks.

In an attempt to get my new venture and my books in order, I ordered a new shed to use as an office. Getting electricity out to it is a nightmare, to get over this issue I chose to fit a solar panel and use Nicds as the storage medium (something I can get for nothing!). On my workbench, I have enough 3V6 1500mah batteries to make a 12v (actually around 15v fully charged) 10.5ah pack but I came to an issue after building my first 12v 1500mah pack, How do I balance charge this and how do I get a 3V6 tap that won’t cause issues.

To this end, I came up with designs for the following sub-packs.

As you can see, the above pack designs are of a different supply voltage.

Why 2 different voltages?

My lighting is supplied from 3V6 recycled Led lighting (ignoring the 240V side) but I also need 12V for the charge controller and inverter required for none 12V equipment!

One of my dilemmas comes from the 12V side. Do I build the packs as 12v packs which are easier to upgrade by adding more packs or, do I build the packs as 3V6 which require me to add cells to all the packs at the same time. The second dilemma comes from keeping them balanced charged.

If anyone knows the answer to this, please tell me which is the best construction method!

ESP8266 -12 NOT beginner friendly

I brought this model because I wanted more GPIO’s and couldn’t find the 12a or 13 version. Man I wish I had ordered the -1 model first as this model is a pain in the ass to get working.
Using the provided wiring diagram and the arduino ide, I get the sync warnings and then the ide freezes during the upload stage (uploading stays in the progress bar!)

Have ordered a -1 model and will try playing with that before going back to the -12.

After 2 years of searching I finally found my battery charger for my 7.2V RC battery’s. They have not been used for nearly 3 years and I am surprised that one of them still works.

it’s a Shame I can not use the same referb system that I used on my Lion’s but I shall find out if the last battery still works tomorrow and run my 1/12 scale scoobie.

The only issue with it currently is the mechanical speed controller. 
The contacts have far to much play on it (and as evident from the sparks it lets off) its not very energy efficient.
