Last year, I bought a Glowing House Set for my Middle daughter. I wanted something that coupled her curiosity in science and her artistic nature. It was both a craft and engineering project.
Over the Christmas holiday, she sat down and made the houses. Putting the houses together, decorating them and creating the electronic circuit. All by herself.
The electronics in the roof are the clever part of the kit. She used electric paint, (the black lines in the photo above) to make the circuit which linked the LEDs to the battery and the light sensor. It’s called cold soldering. A great way for a child to make a circuit without risking burnt fingers.
It worked. The houses lit up when the light sensor was triggered in the evening. Very cool for an eleven year old. Only slight problem was that the blue LED was not lighting up. The rest were working. By then the electric paint was dry and would become brittle if broken. Not great for problem solving, as it would destroy the working part of the circuit, so she carefully removed the blue LED.
She took the problem to her father and he had a solution. (Aren’t Dads great?) He found a breadboard (the white board above, not for slicing loaves) to test the blue LED. It didn’t take long for all the children to join in. Pushing in the jumpers, resistors, transistors and lights. Making LEDs light up and the noise component to vibrate noisily.

They made mistakes. Some components died. I cannot lie, but they had even more successes and they learnt so much. Oh, those curious minds. The hands on experience, of putting the circuits together, was perfect. They were captivated.
Oh, and what of the blue LED?
The original problem?
It was dead. It happens. Do you know what, I’m glad it didn’t work? I would not have thought of buying her a breadboard to experiment with. If all the components had worked in the original kit, she would never have experienced the process of isolating the fault.
She loves both kits and has learnt so much. More importantly, she wants to do more.
Steps on to soap box: This is NOT a sponsored post, in any shape or form. I am fortunate to have an engineering father who saw no reason why his youngest daughter shouldn’t become an engineer too, and provided encouragement. That was me, and I did. I’d like my children to see no barriers to pursuing careers in science or engineering, if they want to, especially my daughters. This kit is perfect for stretching her experience. I also love that it does not patronize her or seem to overtly attract her by being obviously for a “girl”. No stereotypes.
(steps off soap box)
Just before Christmas, I was leafing through my copy of More Last-Minute Knitted Gifts for ……well last minute inspiration. I kept going back to the Soft as Clouds Cowl. I loved the idea of knitting with cashmere. I couldn’t justify the time or expense in the run up to the festive season, so I put it on my “will-do-one-day,-but-probably-not” list.
Can you imagine the squeal when I opened my sister’s present? A ball of Brora cashmere 2ply yarn. All 50g of it. Perfect for the cowl. I couldn’t wait to cast on. I anticipated that if I knitted a few rows a day, I might have it ready for Spring and hopefully there would be enough to do it.
Oh how wrong was I on both counts! It knits up remarkably quick. I think I had knitted almost 3 of the 12 inches, in the first evening.
Next error. I had totally underestimated that 50g of 2ply cashmere provides many more metres of yarn than I imagined. I’m going to have some left over. There is more than enough. (Ravelry notes here)
As it’s Wednesday, I’m sharing my latest read. I bought What If?: Serious Scientific Answers to Absurd Hypothetical Questions for my husband. He thoroughly enjoyed it and passed it on to me to read. (I do like giving gifts that I’d like to receive….but I really did buy this one with him in mind!!)
I’m about half way through and enjoying it. It appeals to my nerdy side, and is written with humour. Like one of those strange conversations that you get pulled into when other subjects run dry. Each person adding/disagreeing/building on what has been said. Until you end up with a solution that involves a new planet made entirely of furry moles.
I know I’m not alone.
So what have you been knitting and reading? Any interesting hypothetical questions discussed over the festive break? I’d love to hear.
