Development of a 3-Phases motor speed control via PWM controlling IGBTs. + Technology watch and R&D. + Electronics Hardware (schematics, BOM, PCB layout including SMPS) . + Embedded software in bare metal C on Microchip PIC p18f4431. + 1KW 3-phases motor. + Current sensing. + H-bridge regenerative breaking. + Flyback DCDC power supply. (2006 – 2008)
A little break in Firmware development to help my client, an IoT start-up, diagnosing The Popcorn Effect. Something I’ve never seen with my own eyes before. The Popcorn Effect is a direct consequence of Moisture entering the IC before the reflow process. A common problem in Electronics Manufacturing. Production and Testing It all started onContinue Reading The Popcorn Effect on MSL 1
This is my first experience with CC2640R2F and also with TI more generally so I thought I’ll write down my feelings after a week as it might be of interest to someone else. Background I should mention that this was my very first time developing with TI, which means most of the comments concern TIContinue Reading Hands on TI CC2640R2F
As for many new starters with Cypress Semi, I didn’t really know the major differences between PRoC and PSoC 4 BLE. In fact I didn’t even realise there was a difference. Yes there is. Luckily enough it is very simple! Cypress PRoC vs PSoC 4 BLE Cypress’ PRoC (Programable Radio On Chip) can be seenContinue Reading Cypress PRoC vs PSoC 4 BLE
After validating the feasibility of my IoT idea, I wanted to start drawing the schematic. There are plenty of PCB layout CAD software. Target3001 was in the list. Why Target3001? I did not own a licence and prices are high, you better choose the right tool. Fortunately most of them have a free trial, perfectContinue Reading PCB layout with Target3001!
Altium Circuit Studio sold by Element14 (Farnell) is a stripped down and cheaper version of the famous Altium Designer. I thought I’ll give it a try as they just reduced the price to about 1000$. This makes it competitive with others in the same feature and price range. I installed the 30 days trial and startedContinue Reading PCB design with Altium Circuit Studio. FAIL.
Chiang Mai is a great place for Digital Nomad makers. There is one issue; If you are asking yourself “where can I buy electronic parts in Chiang Mai?”, this post might help you. Thailand is nothing like Shenzhen in China. So, where to find parts, raw components for makers and repairs? Through holes traditional electronics and breadboardsContinue Reading Finding Electronic parts in Chiang Mai, Thailand
Five months have gone since I first started with Cypress, I have now had the chance to try different aspects of their tools on a personal IoT project. Time do do a Cypress PSoC review. Was Cypress a good choice for the IoT project? Cypress’s PSoC 4 family is great I believe, the devices areContinue Reading Cypress PSoC Review
To choose the right controller for my IoT idea I start by listing the requirements. Some are essential others just nice to have. The controller is the brain of the system. All performances will depend on it so choosing the right device is essential. It is best to make this choice early to avoid a PCB redesign,Continue Reading Choosing the right IoT Controller
For the purposes of my IoT project, I was looking for a makerspace that would allow me to make my IoT prototype. Also called hackerspace, fablad, fabcafé,… some only have basic equipment like a 3D printer and a soldering iron. When it comes to more advanced electronics such as an oscilloscope or SMT reflow facilitiesContinue Reading Working at Makerspace Thailand in Chiang Mai
