But yeah, defo keen to look at the app side, you familiar with the API? Would you want the raw captures then do the processing of the data on the receiving device, or would you want to receive the processed data already? The pro to the former is not needing a powerful microcontroller... Would bring price down more and battery life up!


I'd say raw captures, much more processing power on the phone (or alternate device), plus can also send it somewhere else in case you want to process it again in the future. I haven't found an API I can't work with yet Happy

I knocked up a phone app that tracked a workout (I think I sent you a copy ages ago). Should be easy to knock up a similar prototype linked to your data to test it out.

AMH_Power said:I've started to make my own velocity sensor which uses LIDAR (basically like RADAR, but Lasers instead of radio waves).
It's already fully functional, and rivals the accuracy of my Flex sensor (1000hz polling vs. the flexes 50hz). They are always within 0.01m of each other (I dare say this discrepancy is from the lockout height of left vs right side of the bar!).

It's accurate to 2mm within 4m.

It's currently only on a breadboard and using an Arduino Uno for processing. The final product is going on an Arduino Nano V3 (lower power consumption), will have a li-po battery (will take 10 hours to charge, but will only need charging every 1000 hours!).

I've had a quote for making a milled aluminium case with thick gorilla glass to make the thing bullet proof. It has no buttons beyond on/off, I want it simple as s**t (and cheap!)

I'm keen to get a laser accurate (literally) to lifters for under 120 quid.

Here's the prototype showing behaviour/code:

https://drive.google.com/file/d/1uGIvJAQ9iIWkHXAk0bsFgGVOE59BcMGt/view?usp=sharing

The last few days of learning has been STEEP. But it will be worth it in the end!

Keen for suggestions...

ps. If anyone is wondering, it sits on the floor, builds up a 3D image of everything above it, and then uses the lowest point of the image as the reference (will always be the bottom of the disc or the bar in absence of the disc). The sensor has a 25 degree field of view; so its very accurate even in the presence of lateral(x/y) movement of the bar despite tracking z.


Very nice Aaron.

I bought a Texas Instruments BLE sensortag (20) a while ago that contained an accelerometer and gyroscope amongst other sensors - my aim was to attach it to the bar and transmit the movement data to a phone app for immediate analysis (velocity, bar path etc).

I guess as you have a 3D image you can do bar path too.

Are you intending transmitting the data to an app?

I'd personally go for ply with stable mats on top, though I'd have ply for the foot areas rather than matting as I prefer to squat/dead off something solid. I had all mats previously but much prefer my new setup with ply in the centre.

One downside is obviously that you have to know where your racks will be and they're a pain to move, but who moves them anyway.

Having different density mats in different areas would do my head in too, whatever anyone says you can feel the difference (and for only a few quid savings).

Check the level too, and fix that it it's out before putting anything on top. Don't underestimate the sound transfer with deads, I looked at acoustic matting but that's expensive - more ply rather than more mats for me.

Martin1956 said:Competition Report

At first glance, the result makes grim reading. Those following my progress will know that, before I went to Pilsen at the end of April, I managed a 147.5 bench, my comeback pb. Post Pilsen, I struggled to manage 140.

At Sunday's competition, I managed at 130 opener before failing 135 twice. On the face of it, awful, I've lost 17.5 kilos in bench power in the last month. So for the last 48 hours I've been trying to make sense of things, and here are my conclusions.

My touch and go bench has always been 5 kilos below my paused bench, so on a perfect day, I could have expected 142.5. In reality my best before I left was 140, so on the perfect day I could have expected 135. The reality was I got 130, and probably had 132.5 in me.

That was after getting up at 5.00 am on Saturday, getting to the ferry by 6.00, sailing at 7.00, getting the bus to Inverness, driving down to Glasgow, staying in a B&B and eating takeaway food before getting up early again on Sunday, driving to the venue, weighing in at 9 before lifting at 3. And all that robbed me of another 2.5, which is hardly a great surprise.

So my message to myself is don't be too despondent. I qualified for the British Equipped Bench with my opening classic lift, I have to accept that all the commentary work and travel during what should have been my peaking period has an adverse effect, but it's part of the price to pay for having the privilege of being an EPF commentator.

Also, I 'got away with' opening within 2.5 kilos of my best on the day, I won the Bench title M3, and managed a return to the platform after two years away when it might have been easier just to give up. I also renewed many old acquaintances and made new friends.

Another also - just as lifting affects my golf, so golf affects my lifting. But giving up golf to aid my lifting would diminish me, and so I'll do both as well as I can without sacrificing one for improvement in the other.

And last, but by no means least, I managed my warm up and all three lifts without any wrapping, something I couldn't have dreamed about a month or two ago. So there is definite improvement in the trapped nerve.

I know I have lots of work to do to get back to where I want to be, and Sunday was a stark reminder that the platform and the home gym are two very different beasts. But after a couple of days rest, the next phase of my recovery begins.

My overriding emotion is one of disappointment to be honest, but let's take the positives and move on. I'm back...


I'll go with the positives - well done!
