RSC- The safety car can now automatically come out on-track, and has a timing adjustment to come out just in front of the procession leader. When a restart to Green is initiated, the RSC heads to the ...

Ok we have a PCB design for the opto tacho  already. As Nitrous dongles are due to be ordered, the opto sensor tacho board was added to the left hand side as a snap off to save set up and tooling cost...

I must admit it is rewarding. Turning ideas into reality is fun.    Even with some hiccups. :thumbup:

I’m trying to imagine a brushless driver, Scorpius car decoder, Carrera car decoder, comprehensive light board all in one board 24.8x19.2 instead of 3 seperate boards, complete with opto tacho, OLED, ...

Exact percentages of sensored versus sensorless (unsensored) brushless slot car motors are not readily available in current data or industry reports, as this specific niche lacks comprehensive market ...

Couldn’t help myself. I ordered one of these today for John on his recommendation. A Texas Instruments BLDC development board. Off their website:  The MCF8316D evaluation module (EVM) enables users to...

Plan C Tacho. Ok so BEMF is out and the hall will possibly use all the CPU capacity. But is there another way? What about this?  A tiny 1.6x1x0.5 SMD reflective optical sensor mounted on a PCB that i...

Hall sensors arrived yesterday. We found analogue sensors better for the task but still fuzzy on the scope. So a Fourier Analysis is first required, then lots of algorithmic work and firmware, with a ...

So the factory in Taiwan sent the OLED screen plug in in wrong wiring config and wire gauge. I’ve also decided I want to keep the wires more discreet so good old red and black will be used not yellow,...

I was just thinking about the MPD, could it be used as a controller PCB? Let’s check it out. First of all we need micro, tick, Next we need a throttle mechanism,  could we use a hall sensor and $2...

Hi Kevan,   What we discovered today was quite interesting.  Because the PWM frequency is fixed and RPM varies depending on PWM duty cycle and motor load BEMF cannot be measured reliability. So ok for...

Vapour research. Both Back-EMF (BEMF) and Hall effect sensors can be used for motor tachometry, but they have different characteristics and applications. BEMF is an indirect method, relying on measuri...

Some more imaginary vapour work analysing BEMF waveforms this morning  :wavegreen: :rofl:

Ok, so where are we up to? Well hardware development is 100% complete. V5.4 was the 10th iteration (hardware) so ten versions in 24 months. Not bad. So now it’s a new stage for the team, purely firmw...

So conclusion: I’ve decided the only professional solution is actually a dedicated MPD car decoder for brushless. One neat tidy chip that does brushless motors. And one for non brushed. I’d imagine th...

A bit more fun……I asked AI (Grok) who manufactures the world’s most advanced wireless digital slot car system. Answer: Determining the manufacturer of the “world’s most advanced wireless digital slo...

Just a bit of fun. Thought I’d check out some AI. AI knows Scorpius is cutting edge. Cool. :cool: [attachment=41362]

So to power the Texas Instruments ESC should the team source power off the rails or power from MPD? As PSUs vary, some are PWM, some are not. And as the frequency of the PWM of the power supply is gen...

Oh no another mistake!  Just when you think you have it licked. The MPD specification stipulates 2 seperate photo transistor circuits. This is required for anti collision on the proposed Carrera Lane...
