Best, cheapest, DIY hacks for standing desk for laptop, tablet, etc

I’d highly recommend a tablet (most ppl likely have sitting around the house) and a simple ipad/music stand. I grabbed a stand a month ago and LOVE it. It was about $25. I set it a bit lower than my handle bars and have my Bluetooth earbuds on watching a movie on a tv. This is great as the tablet isn’t in the way of tv.
