Glue and solder, fixing some techie bits

Kate's glasses, fix with teeny torx screw taken from old mobile phone.

Rubber handle on knife glued with gorilla glue.

Brush handle gorilla glue fix. 2 shards from handle turned up. One in fruit bowl. One in bike tyre that has been hanging around kitchen.

Bike phone holder, glued rubber onto broken plastic interior threaded tension arm, hopefully will make it hold better.

Usb chargable bike light. Plastic snapped apart using sharp knife, potato peeler. The led array part, one leg was snapped, broken connection. Charged it up. Holding broken leg down allowed light to operate. When soldering other leg broke! So soldered both legs, plastic snapback together .. use vaseline ? Waterproof? Not sure. Protect with duct tape.

Bikemate rear light 3.7V 800mAh, micro usb charging port pins inside are mashed, cannot charge. Very difficult to disassemble. Heat middle metal sheath then lever off top red light stiff plastic & bottom softer black plastic. TODO. going to be quite difficult to fix, unsoldering and replacing port, myeh, maybe, just add 2/3 wires and expose them charge with croc clips maybe.


MTB front derailleur removed. It stays in gear, pretty much. 


Hybrid bike rear derailleur realigned using pliers wrench holding sprockets, technique a bit cave man ish, it's not skipping some gears any more so phew, relief, happy days.

Learning to wheelie MTB

KEY breakthrough point for me: Come to complete stop(just about almost), use brakes before you pop for wheelie.

I practiced a good bit before, but failed to get pedal push to pop front wheel up. I think due to ... saddle height, timing, posture.

Watched this again today. Essentials:

5 steps to wheelie by daily MTB rider
* bike setup, saddle, which gear
* preload and pop
* shoulders back(and arms straight), eyes forward
* pedal brake hips
* practice practice practice

Proper setup saddle height(quite high but not very high), 
Gear not too small/big.
Slight uphill helps.
Head up look forward. (Sometimes catch self looking at wheel or pulling front wheel to side)
Dip doesn't have to be too much, not down to handlebars, just bunch dip a maybe 8"or so then arms straight, look up/forward.



Sandyford ind est, 16:20ish getting initial pop front wheel high sometimes. Whee. Straight down though almost every time. Stop, hup drill. 




Try to get left leg pedal stroke.
.... myeh. Left leg really bad at that.

Phooopf. Feel it in shoulders a bit now.


You don't have to preload.
I wasn't preloading earlier.

But I discovered preloading . . .

You can have a little bit more speed at start with preload. Preload pop(arms and pedal) are very fast. Down up. Preload is a hard push down. Bang-pop.

I managed to get almost one two three pedals a couple of times.


Practicing pops just before up kerb and down also.
