I haven't done much this week except looking for a workshop (been to 3 mechanical workshops and all were busy) where I can remove the corrugation of my rebars. I applied for a trial version of MatLab but mathworks haven't replied about the result. Ma...
Sorry for not posting anything as summer holidays have started and I was away for a couple of weeks. I broke off the PCB coil and instead soldered a connector to the evaluation module. This is how my setup with the custom coil looks like:&...
This week I worked on my moulds; 160 pcs. It is made of chipboard and coated it with a wood glue so that water won't be absorbed. I also prepared cement, sand, and gravel for next week's task. I used my friend's abandoned house as my workshop . ...
I redesigned my mould. The cylindrical type of mould can be easily made but the steel would be placed vertically and I have to make it stable. Therefore it is prone to error when the steel is not centered. I have redesigned it to be a rectangular blo...
I am still working on this project, but again it has been very difficult to find the time to finish things up. It has been a very hectic period at work and I've also just signed a contract for a new job next year. I've also had a ton of practical pro...
This week I studied the best coil diameter/ratio for my project. Also contacted some people who'll let me borrow their oscilloscope.Experiment will start on week 8.
I interviewed a few civil engineers about the curing process in construction. I decided to cure the cement for 14 days and take the inductance reading after. I still haven't started the experiment coz I’m waiting for the approval of my needed materia...
Since my last blog post I have created a custom coil. It is a 14cm coil with 7 turns of 0.4mm enamelled copper wire.For the purpose of finding the correct value of the filter capacitor, I ordered capacitors in the range from 20pF to 100nF as specifie...
The past weeks I've been quite busy, so I do not have alot of updates so far. Therefore I decided to make a combined blog for weeks 6 and 7 as I did for weeks 2 and 3. Thoughts on the frequency counter in the LDC1000I had another look at the...
This week, while waiting for the budget (for construction materials) to be approved, I talked with a MathWorks account manager for my application to get a free license of MatLab. I'm not sure it it'll be granted but it's worth the shot. I also starte...
This week I got to check with construction material suppliers and ask for a quotation. I've also negotiated a place where I can do my concrete mix, water curing, and conduct inductance test. Here’s the list of materials needed:Rebars10 mm dia. Grade ...
This week I focused mostly on the software for the LDC1000EVM. There are many questions on the ask TI forum about the protocol which is used on the LDC1000EVM, but there is no real single answer. What is known is that the LDC1000EVM uses a USB CDC (C...
hello, i am back, sorry for the bit late response, i was kind of busy with my exams.so cant focus on the current project much i received my shipment from element14 Bangalore,it was a bit huge box,and i found a small glass box with the evm kit, a...
I already started with some tests using the evaluation board and software, looks very promising for all ideas but has to be refined the 'Mythbusters'-way! So it's all about coil design and I already ordered some PCBs. Time is running fast and I have ...
Did NOT use the 'F'-word here but, in case you are not involved in making films or movies, is a 'follow focus' Here's a short explaination ... Let's take a look at the two pictures above derived from a short scene I...
Anyone a clue about this circuit ? What is it used for ? Make an educated guess! Lots of coils, capacitors and analog stuff inside, YES, it's a Theremin, a musical instrumet that was popular in the late 70th. Basically there are two antenna...
Playing some electric guitar I never liked that good pickups can be extremly expensive. From the engineer's point of view, I did never understand why there are only few active pickups and why not imtegrate the Amp and ADC into the guitar (also th...
First of all, I lost some time when the road test started but let's try to catch up and introduce my ideas ... I'm very proud of my cooking skills and ad do like doinb BBQ. Actually the kitchen is my Domain in my Family. So, for examampl...
