Re: View AutoCad Drawings

You could try looking at DraftSight by Dassault Systemes. Its an AC clone with a free-to-use basic version plus paid upgrade options.
Mainly windows, but mac and linux are availably unsupported.

Re: What day was 1st RPI sold?

If I remember correctly, the Foundation put a few Pis onto eBay before the official launch. I think they were pre-production examples and were auctioned for charitable reasons. Might they count as the first Pi sales?

Re: X-Y-Z Axis Rig

May I suggest you look at 3D printers for a start point? Most of the controller boards are built around Arduinos. There's plenty of documentation on t'web for open source hardware to scratch build a rig, or you could get a Prusa i3 clone kit and modify to suit. Keeping it Pi would require a bit more...

Re: How to remotely push a button?

Find yourself an old school chime door bell. The sort that goes "ding dong" by shooting a battery powered solenoid against a couple of metal bars. Replace the door bell switch with suitable control circuitry and let the solenoid push the button.

Re: Measuring frequency

sharix / Gert, If you're OK with a binary divider then a 4024B Binary counter might be another suitable choice. Feed the input frequency to pin 1 and tap the most suitable output pin (1/2 - 1/128) for a simple frequency division. For instance, 40kHz (ultrasound receiver) input, pin 5 is 1/32 divisio...

Re: shopping list

My twopenn'th, based on cold hard (and brief) experience: Don't scrimp on the power cable. Cheap cables lead to just enough voltage drop to make SD cards fall over during boot (error -110), which leads to inexperienced user (yours truly) suspecting branded SD card might be fake and shelling out good...

Hello MaDoGK I've found the Logitech K400 quite good. RPi found it no probs. It runs on two AA batteries and can be turned off when (or if) you need.

Re: Error -110

I agree completely, I took the voltage readings to confirm to myself that the cable was to blame originally. Its been relegated to the "old USB cables" bin now. I did find it strange that the Pi booted with it after the card had been "proved good" to it.

I had the -110 error with my first SD card (8gig C6 Toshiba) last weekend. I'd powered the RPi through a cheap micro USB lead from an old mains powered USB1 hub. Searching the forums for "110" resulted in a couple of posts commenting about voltage drop over cheap cables, so I tried a Nokia USB charg...

I'm normally risk-averse to betas, but I'll give that a go. I've also seen from other posts on the os/arch forum that my fun with that distro (no HDMI - which I forgot to mention in my post - but RCA quite happy) is for deffo a config.txt issue.
