I’m a big fan of XBMC, and have an Ouya running XBMC set up in my lounge, streaming from my NAS. I normally use XBMC remote on my phone for controlling it, but this gets annoying when the phone is on charge, or I’m using it for something else. I noticed that the majority of […]
Over the weekend I ordered the mainboard for the new robot. It contains an arduino, battery voltage monitoring, battery regulation and a pair of motor driver chips.
It is designed to sit on top of a hardcase 5Ah LIPO, with short leads going into the b…
Last night I retrieved the first chassis printout and did a test assembly with the parts that have arrived. It looks good! The axle distance is perfect, the chunks I carved out for the pi are all the right sizes, and it looks bitchin. The only negative was that the mount for the raspberry pi […]
Before leaving the hackspace on saturday, I set the wheels and motor mounts for my robot printing, as I figured these parts probably wont change while I finish the rest of the design. Tonight, I cleaned up the printed parts, and did a test assembly of the track sets: They looked about right, so I […]
Here is a teaser shot for my new rover robot, based around a raspberry pi and a massive lithium battery. Fairly heavily inspired by Wlll’s ball collecting robot.
Last night we did more work on our CNC machine, and got the z axis hooked up and working. Just need to add an endstop , fix the y endstops in correctly, extend some wires, and we’ll be ready for our first cut!
Tonight we had our 4th CNC night. We rebuilt the Y axis of the proxxon mf70 mini mill we’ve been converting using a 3d printed bubblegumcnc kit. After building the axis, We hooked up our GRBL shield and managed to get the machine moving the X and Y axes properly under its own power. We […]
Its taken many months, and millions of pounds of r&d, but we have finally completed the design for our mendel90 heated chamber. Heated chamber kits will be available soon, for a bargain price of £99.99 plus shipping.
I added a prototype lifter arm to my robot yesterday. It needs re-doing (it’s unreliable and heavy) but it works for now. I’m using a new motor driver circuit for it as I burned out the SN754410 motor driver I was using, the lifter motor seems to peak briefly at about 1.5 amps when starting to […]
